Problems to be solved by the invention

However, in a component mounting machine, a plurality of feeders are generally used for component supply, and if component feeding is performed individually for these feeders, the work efficiency is not necessarily good, and the above-described technique cannot sufficiently cope with this.

The present invention has been made in view of the above problems, and an object thereof is to provide a technique capable of efficiently replenishing components to a feeder.

Means for solving the problems

The component replenishment support device according to the present invention includes: a storage unit that stores a production plan for producing a substrate on which components are mounted by a component mounting machine in which a plurality of feeders each having a mounting location are arranged in a component supply unit, the plurality of feeders supply components stored in component storage parts mounted to the respective mounting locations, and a mounting head mounts the components supplied by the feeders onto the substrate; and a calculation unit that calculates a preparation plan indicating component housing members to be held by holding units of the supply cart for preparation for a collective supply of the component housing members held by the holding units corresponding to the plurality of feeders, respectively, by attaching the supply cart having the plurality of holding units corresponding to the plurality of feeders, respectively, to the component supply unit, based on the production plan, and collectively mounts the component housing members held by the holding units corresponding to the plurality of supply-target feeders, respectively, of the plurality of feeders, to the mounting positions of the plurality of supply-target feeders, respectively.

The component replenishment support method according to the present invention includes: a step of obtaining a production plan for producing a substrate on which components are mounted by a component mounting machine in which a plurality of feeders each having a mounting location are arranged in a component supply section, the plurality of feeders supply components stored in component storage parts mounted to the respective mounting locations, and a mounting head mounts the components supplied by the feeders on the substrate; and a step of calculating a preparation plan indicating component accommodation components to be held by holding units of the supply cart for preparation of a collective supply by attaching the supply cart having a plurality of holding units corresponding to the plurality of feeders to the component supply unit, based on the production plan, wherein the collective supply is performed by attaching the component accommodation components held by the holding units corresponding to the plurality of feeders to the mounting locations of the plurality of feeders.

The present invention (component replenishment support apparatus, component replenishment support method) thus configured can efficiently replenish components in a component mounting machine in which a plurality of feeders each having a mounting location are arranged in a component supply section, and a plurality of feeders supply components accommodated in component accommodating members mounted to the respective mounting locations. Specifically, the supply carriage is used when supplying components to a feeder of the component mounting apparatus. The supply cart includes a plurality of holding portions corresponding to the plurality of feeders, respectively. Further, by mounting the supply carriage on the component supply section of the component mounting machine, it is possible to collectively mount the component accommodating parts held by the holding sections corresponding to the plurality of supply target feeders out of the plurality of feeders, on the mounting positions of the plurality of supply target feeders. In particular, a preparation plan indicating the component housing members to be held in the holding section of the supply cart for preparation for batch supply is calculated based on a production plan for producing substrates on which components are mounted. Therefore, the component storage parts can be supplied to the plurality of supply-target feeders by preparing the component storage parts on the supply carriage based on the production plan in parallel with the component mounting by the component mounting machine and performing the collective supply at the timing when the supply is necessary. Thus, in the present invention, the component can be efficiently replenished to the feeder.

Further, the component replenishment support device may be configured to: the system further includes a preparation plan display unit that displays a preparation plan for the operator. In this configuration, the operator can prepare the component housing member on the supply cart while checking the preparation plan displayed on the preparation plan display unit.

Further, the component replenishment support device may be configured to: the component housing member is provided with component information indicating information on the component housed in the component housing member, and the control unit issues a warning to an operator when a result of obtaining a correspondence relationship between the holding unit and the component information of the component housing member held by the holding unit does not comply with the preparation plan. In this configuration, when an error occurs in the preparation operation of the component storage member to the supply cart, a warning can be given to the operator.

Further, the component replenishment support device may be configured to: the component housing unit is provided with component information indicating information on components housed in the component housing unit, the feeder is provided with feeder information indicating information on the feeder, the control unit obtains a correspondence between the holding unit and the component information of the component housing unit held in the holding unit and a correspondence between the holding unit and the feeder information of the feeder corresponding to the holding unit, and when the supply carriage is mounted to the component supply unit, component feeder information indicating that the component information of the component housing unit held in the holding unit is associated with the feeder information of the feeder is generated for the holding unit and the feeder corresponding to each other. In this configuration, component feeder information is generated in which component information of the component accommodating member held by the holding unit is associated with feeder information of the feeder in association with mounting of the supply cart to the component supply unit. Therefore, the arrangement of the component accommodating member after component replenishment with respect to the feeder can be accurately grasped from the component feeder information.

Further, the component replenishment support device may be configured to: the plurality of feeders have a detection unit that detects attachment of the component accommodating member to the attachment site of each of the plurality of feeders, and when the replenishment carriage is attached to the component supply unit, the control unit generates component feeder information for the replenishment target feeder, among the plurality of replenishment target feeders, for which attachment of the component accommodating member to the attachment site is detected, and does not generate component feeder information for the replenishment target feeder for which attachment of the component accommodating member to the attachment site is not detected. In this configuration, for example, when a situation in which the mounting of the component storage member to the feeder to be replenished has failed due to a trouble during the conveyance of the replenishment carriage or the like occurs, appropriate component feeder information reflecting the situation can be generated.

Further, the component replenishment support device may be configured to: the control unit issues a warning to the operator when the presence of the feeder to be replenished for which the arrangement of the component accommodating member to the mounting position is not detected is confirmed after the replenishment carriage is mounted to the component supply unit. In this configuration, for example, when a failure occurs in mounting the component storage member to the feeder to be replenished due to a trouble during conveyance of the replenishment carriage, a warning can be given to the operator.

Further, the component replenishment support device may be configured to: the plurality of feeders include a detection unit that detects attachment of the component accommodating member to the attachment site of each of the plurality of feeders, and the control unit issues a warning to an operator when attachment of the component accommodating member to the attachment site of a feeder other than the feeder to be replenished among the plurality of feeders is detected in association with attachment of the replenishment carriage to the component supply unit. In this configuration, when the component housing member is erroneously mounted on a feeder different from the feeder to be replenished, a warning can be given to the operator.

Further, the component replenishment support device may be configured to: the component supply unit includes a reading unit that reads an identifier attached to the component supply unit, and the control unit issues a warning to an operator when a combination of the component supply unit and the replenishment carriage indicated by the identifier read by the reading unit is inappropriate. In this configuration, it is possible to suppress the supply cart from being attached to the wrong component supply site.

Further, the component replenishment support device may be configured to: the component housing member is a component supply tape for housing components, a preceding tape placing unit and a following tape placing unit for respectively holding the component supply tape are capable of engaging and disengaging with respect to the feeder, one of the preceding tape placing unit and the following tape placing unit is engaged with the feeder, so that the component supply tape held by the one tape placing unit is attached to an attachment position of the feeder, the following tape placing unit is attachable to a holding portion of the supply carriage, the following tape placing unit is attached to the holding portion, so that the component supply tape held by the following tape placing unit is held by the holding portion, and when the supply carriage having the following tape placing unit attached to a component holding position corresponding to the supply target feeder is attached to the component supply portion in a state where the preceding tape placing unit is engaged with the supply target feeder, the subsequent tape placing unit is engaged with the feeder to be replenished while pushing out the preceding tape placing unit and separating the preceding tape placing unit from the feeder. In this configuration, the tape placing unit attached to the feeder to be replenished is replaced from the preceding tape placing unit to the succeeding tape placing unit by the operation of attaching the replenishment carriage to the component supply unit, whereby the component supply tape held by the succeeding tape placing unit can be easily attached to the feeder to be replenished.

The component mounting system according to the present invention includes: the component replenishment support device; and a component mounting machine in which a plurality of feeders each having a mounting portion are arranged in the component supply portion, the plurality of feeders supplying components accommodated in the component accommodating parts mounted to the respective mounting portions, and the mounting head mounting the components supplied by the feeders on the substrate. Therefore, the component can be efficiently replenished to the feeder.

Effects of the invention

According to the present invention, component replenishment to a feeder can be efficiently performed.

Detailed Description

Fig. 1 is a plan view schematically showing an example of a component mounting apparatus according to the present invention. Fig. 1 shows an XYZ rectangular coordinate system including a Z direction parallel to the vertical direction, and an X direction and a Y direction parallel to the horizontal direction, respectively. The component mounting apparatus 1 includes a pair of

conveyors

12, 12 provided on a base 11. The component mounting apparatus 1 mounts components on a substrate B which is carried in from the upstream side in the X direction (substrate conveying direction) to a working position (position of the substrate B in fig. 1) by the conveyor 12, and carries out the substrate B on which the components are mounted from the working position to the downstream side in the X direction by the conveyor 12.

The component mounting apparatus 1 is provided with a pair of Y-

axis rails

21, 21 extending in the Y direction, a Y-axis ball screw 22 extending in the Y direction, and a Y-axis motor My that rotationally drives the Y-axis ball screw 22, and a head support member 23 is fixed to a nut of the Y-axis ball screw 22 in a state of being supported by the pair of Y-

axis rails

21, 21 so as to be movable in the Y direction. An X-axis ball screw 24 extending in the X direction and an X-axis motor Mx for rotationally driving the X-axis ball screw 24 are attached to the head support member 23, and the head unit 3 is fixed to a nut of the X-axis ball screw 24 in a state of being supported by the head support member 23 so as to be movable in the X direction. Therefore, the head unit 3 can be moved in the Y direction by rotating the Y-axis ball screw 22 by the Y-axis motor My, or the head unit 3 can be moved in the X direction by rotating the X-axis ball screw 24 by the X-axis motor Mx.

Two component supply units 25 are arranged in the X direction on both sides of the pair of

conveyors

12, 12 in the Y direction, and a plurality of tape feeders 4 are arranged in the X direction in each component supply unit 25. Each tape feeder 4 has a component supply position 40 at a front end portion on the conveyor 12 side, and supplies components accommodated in a component supply tape TP (fig. 2 and 3) to the component supply position 40. The component supply tape TP stores components in each of a plurality of pockets arranged in a row at equal pitches, and the tape feeder 4 intermittently feeds the component supply tape TP in the Y direction by the pitch, thereby supplying the components to the component supply position 40. The element accommodated in the element supply tape TP is a small-sized electronic element such as an integrated circuit, a transistor, or a capacitor.

The head unit 3 has a plurality of (4) mounting heads 31 arrayed in the X direction. Each mounting head 31 has a long shape extending in the Z direction (vertical direction), and can suck and hold a component by a suction nozzle detachably attached to a lower end thereof. That is, the mounting head 31 moves above the tape feeder 4, and sucks the component supplied to the component supply position 40 by the tape feeder 4. Next, the mounting head 31 moves above the substrate B at the working position to release the suction of the component, thereby mounting the component on the substrate B. In this way, the mounting head 31 performs component mounting for sucking the components supplied to the component supply position 40 by the tape feeder 4 and mounting the components on the substrate B.

Fig. 2 is a side view schematically showing an example of the structure and operation of the belt feeder. In this figure and the following figures, the feeding direction Df (parallel to the Y direction) in which the component supply tape TP is fed out by the tape feeder 4 is appropriately shown, and the arrow side in the feeding direction Df is treated as "front" of the feeding direction Df, and the opposite side to the arrow in the feeding direction Df is treated as "rear" of the feeding direction Df. That is, the conveying direction of the component supply tape TP corresponds to the front side (the other side), and the side opposite to the conveying direction corresponds to the rear side (the one side). In this and the following figures, different reference numerals TP1 and TP2 are used as appropriate for the carrier tape in order to distinguish between the two component supply tapes TP that can be mounted on the tape feeder 4.

The tape feeder 4 includes a feeder body 41 having a mechanical structure, and motors Mf and Mb for driving the feeder body 41. The feeder main body 41 has a flat housing 42 that is thin in the X direction and long in the feeding direction Df. A feeder ID421 made of a barcode is attached to a side surface of the housing 42. The feeder ID421 is unique and can be used to individually identify the tape feeder 4 to which the feeder ID421 is attached. A tape insertion opening 43a (indicated by a broken line) extending in the Z direction is opened at the rear end of the housing 42 in the feeding direction Df, and the component supply position 40 is provided on the upper surface of the housing 42 in front of the feeding direction Df. A tape feed path 43b extending from the tape insertion port 43a to the component supply position 40 is provided in the feeder main body 41. The feeder main body 41 receives the driving force of the motors Mf and Mb, and feeds the component supply tape TP inserted into the tape transport path 43b from the tape insertion port 43a in the feeding direction Df, thereby supplying the component to the component supply position 40.

Specifically, the feeder main body 41 includes a sprocket 44 disposed above the tape conveying path 43b and adjacent to the tape insertion opening 43a, and a gear 45 for transmitting the driving force of the motor Mb to the sprocket 44 in the housing 42, and the sprocket 44 is rotated by the driving force generated by the motor Mb. The feeder body 41 further includes a bracket 411 that can engage with the tape placing unit 5. The carriage 411 is provided at the rear end portion of the feeder main body 41 so as to extend in the feeding direction Df and project rearward, and the lower side of the carriage 411 serves as a space for disposing the tape placing unit 5 to be engaged with the carriage 411. The tape placing unit 5 engaged with the bracket 411 faces the sprocket 44 from below, and the component supply tape TP is engaged with the sprocket 44 by sandwiching the component supply tape TP between the tape placing unit 5 and the sprocket 44. Thus, the component feeding tape TP can be mounted at the mounting portion 441 between the sprocket 44 and the tape placing unit 5. Further, the sprocket 44 is thereby rotated while engaging with the component supply tape TP, and can feed the component supply tape TP in the feeding direction Df. The feeder main body 41 includes a sprocket 47 disposed at a distal end portion thereof and adjacent to the belt conveying path 43b from below, and a gear 48 for transmitting a driving force of the motor Mf to the sprocket 47 in the housing 42, and the sprocket 47 is rotated by the driving force generated by the motor Mf. Therefore, the sprocket 47 can intermittently convey the component supply tape TP in the feeding direction Df by intermittently rotating while engaging with the component supply tape TP.

The feeder body 41 has a cutter that contacts the component supply tape TP on the upstream side in the feeding direction Df of the component supply position 40. The cutter cuts the cover tape of the component feeding tape TP intermittently fed in the feeding direction Df at the center and winds the cover tape up to both sides, thereby exposing the components fed to the component feeding position 40. The structure for exposing the elements in this manner is the same as that described in japanese patent laid-open publication No. 2015-053320, for example. However, the specific structure for exposing the element is not limited to this example. That is, on both sides in the width direction (direction orthogonal to the longitudinal direction) of the component supply tape TP, adhesive portions to which the cover tape is adhered are provided so as to sandwich the storage portions (pockets) of the components. It is also possible to expose the components by peeling one of the adhesive portions while leaving the other adhesive portion, and rolling up the cover tape.

Step S11 corresponds to a state in which the component supply tape TP1 is used for component mounting by the mounting head 31. That is, in the feeder main body 41, the component supply tape TP1 is inserted along the tape conveying path 43B, and the sprocket 47 intermittently conveys the component supply tape TP1 in the feeding direction Df, thereby supplying the component to be mounted on the substrate B to the component supply position 40. Further, in step S11, the leading end of the component feeding tape TP2 for component mounting following the component feeding tape TP1 is mounted between the sprocket 44 and the tape placing unit 5. In this way, the component supply tape TP2 to be used next waits at the rear end portion of the feeder main body 41.

When the component supply tape TP1 runs out of components and the tape feeder 4 discharges the component supply tape TP1 as shown in step S12, the loading shown in step S13 is performed. Specifically, the sprocket 44 starts rotating to feed the component supply tape TP2 in the feeding direction Df toward the component supply position 40, and the front end of the component supply tape TP2 engages with the sprocket 47. Next, in step S14, for example, when the worker detaches the tape placing unit 5 from the housing 42, the component supply tape TP2 is disengaged from the sprocket 44 and falls down to the tape conveying path 43 b. Thus, the sprocket 47 can intermittently convey the component supply tape TP2 in the feeding direction Df and supply the components in the component supply tape TP2 to the component supply position 40. Incidentally, it may also be configured to be able to perform the intermittent conveyance of the component feeding tape TP in a state where the tape placing unit 5 is mounted to the casing 42. Specifically, the sprocket 44 may be provided with a one-way clutch that rotates following the movement of the component supply tape TP to the front side in the feeding direction Df when the motor Mb is stopped, and restricts the movement of the component supply tape TP to the rear side in the feeding direction Df.

Fig. 3 is a diagram schematically showing a relationship between a component supply reel holding a component supply tape and a tape feeder. The component supply reel 6 has a shaft center 61 and two side plates 62 sandwiching the shaft center 61 from both sides, and supports the component supply tape TP wound around the shaft center 61 from both sides via the side plates 62. The component supply reel 6 has a reel ID63 and a component ID64, each of which is formed of a barcode, on the side plate 62. The reel ID63 is unique and can be used to individually identify the component supply reel 6 to which the reel ID63 is attached. The component ID64 indicates information (the type, number, etc. of components) about the components stored in the component supply tape TP of the component supply reel 6 to which the component ID64 is added. The reel ID63 and the component ID64 are not necessarily constituted by separate bar codes, and may be constituted by one bar code.

In this way, two component supply reels 6 are disposed for one tape feeder 4, and two component supply tapes TP drawn out from the two component supply reels 6 can be mounted on the one tape feeder 4. Of the two component supply reels 6, one component supply reel 6 is held at the lower holding position Ll, and the other component supply reel 6 is held at the upper holding position Lu above the lower holding position Ll.

In contrast, the component mounting apparatus 1 includes: a feeder mounting carriage 7 that holds the component supply reel 6 at a lower holding position Ll; and a component supply cart 8 for holding the component supply reel 6 at an upper holding position Lu. The specific configurations of the feeder mounting carriage 7 and the component replenishment carriage 8 will be described later, and these are schematically and simply shown in fig. 3. The feeder mounting carriage 7 and the component replenishment carriage 8 are both detachably mounted to the component supply unit 25. As described later, the tape feeder 4 is detachably mounted on the feeder mount carriage 7, and the feeder mount carriage 7 functions to hold the tape feeder 4 in addition to the function of holding the component supply reel 6. The feeder mounting carriage 7 is mainly used for preparation work for disposing the tape feeder 4 and the component supply reel 6 in the component supply unit 25, and the component replenishment carriage 8 is mainly used for replenishment work for replenishing the component supply reel 6 to the component supply unit 25.

All the tape feeders 4 attached to the component supply unit 25 are not limited to those of the type shown in fig. 2 (referred to as "automatic loading type" in the present specification). Therefore, a part of the tape feeder 4 of the component supply unit 25 may be a type of feeder capable of mounting only a single component supply tape TP. The component supply reel 6 on which the component supply tape TP attached to the tape feeder 4 of this type is wound is held by the feeder mount carriage 7, but not held by the component supply carriage 8.

Fig. 4 and 5 are right rear perspective views of the feeder mounting carriage and the component supply carriage as viewed from right obliquely rear, and fig. 6 is a left rear perspective view of the feeder mounting carriage and the component supply carriage as viewed from left obliquely rear. Fig. 4 shows a state in which the tape feeder 4 and the component supply reel 6 are removed from the feeder mount carriage 7 and the component supply reel 6 is removed from the component supply carriage 8, fig. 5 shows a state in which a plurality of tape feeders 4 and one component supply reel 6 are held by the feeder mount carriage 7 and a plurality of component supply reels 6 are held by the component supply carriage 8, and fig. 6 shows a state in which one tape feeder 4 is held by the feeder mount carriage 7 and the component supply reel 6 is removed from the feeder mount carriage 7 and the component supply carriage 8.

The feeder mounting carriage 7 includes a bottom plate 711 disposed horizontally and two side wall plates 712 vertically erected from both ends of the bottom plate 711 in the X direction. The bottom plate 711 has a peripheral edge formed by two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and is rectangular in a plan view. Each side wall plate 712 is attached to the bottom plate 711 in parallel to the feeding direction Df and the Z direction. Further, the feeder mount carriage 7 has a beam 713 extending in the X direction between the two side wall plates 712. The beam 713 is bridged between the upper ends of the two side wall plates 712 at the front ends of the two side wall plates 712.

The feeder attaching carriage 7 further includes casters 714 attached to four corners of the lower surface of the base plate 711, and the casters 714 support the base plate 711 on the floor (the installation surface of the feeder attaching carriage 7). Therefore, the feeder mount carriage 7 can move the caster 714 while rotating, according to an external force from an operator, an unmanned transport vehicle, or the like. In particular, the two side wall plates 712 are provided with handles 715 projecting obliquely upward and rearward, respectively, and the operator can move the feeder mount carriage 7 by operating the handles 715.

The feeder mount carriage 7 includes a mounting plate 716 attached to the upper end of the beam 713, and two side plates 717 attached to both ends of the mounting plate 716. The mounting plate 716 is disposed horizontally, and each side plate 717 protrudes forward in the feeding direction Df from the mounting plate 716. Further, the feeder mount carriage 7 has a support plate 718 extending in the X direction between the two side plates 717. The support plate 718 is disposed horizontally between the lower ends of the two side plates 717.

The feeder attachment carriage 7 has two

engaging projections

719a, 719b arranged parallel to the feeding direction Df on the inner side of the side plate 717. These engaging

projections

719a, 719b project inward from the inner wall of the side plate 717 (i.e., toward the space sandwiched between the two side plates 717 in the X direction). The engaging projections 719a are disposed on the rear side in the feeding direction Df of the engaging projections 719 b.

The feeder mount carriage 7 has a feeder mount 73 disposed between the two side plates 717 and above the support plate 718, and the feeder mount 73 is supported by the two side plates 717 and the support plate 718. In the feeder mounting section 73, a plurality of feeder slots 731 (placement positions S) are arranged in the X direction, and the tape feeder 4 can be detachably mounted in each feeder slot 731.

The feeder attaching carriage 7 further includes a reel holding portion 75 disposed between the two side wall plates 712 and above the bottom plate 711, and the reel holding portion 75 is supported by the two side wall plates 712. In the reel holding portion 75, a plurality of reel holders 751 (reel holding positions) are arranged in the X direction, and the component supply reel 6 can be detachably mounted on each reel holder 751. Each of the reel holders 751 holds the mounted component supply reel 6 at a lower holding position Ll (fig. 3).

In the feeder installation carriage 7, the plurality of reel holders 751 are provided so as to correspond to the plurality of feeder slots 731, respectively. That is, the component supply tape TP drawn out from the component supply reel 6 held by one reel holder 751 is attached to the tape feeder 4, and the tape feeder 4 is attached to the feeder slot 731 corresponding to the one reel holder 751.

The feeder mounting carriage 7 has a disposal box 77 placed on the upper surface of the bottom plate 711 below the feeder mounting section 73 and the reel holding section 75. The component supply tape TP discharged from the tape feeder 4 is discarded in the discard box 77.

The component replenishment carriage 8 has a bottom plate 811 and an insertion plate 812, which are horizontally arranged. The bottom plate 811 has a peripheral edge formed by two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and is rectangular in plan view extending in the X direction. The insertion plate 812 has a peripheral edge formed by two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and is a rectangle extending in the feeding direction Df in a plan view. The insertion plate 812 is attached to the bottom plate 811 so as to protrude from the center of the bottom plate 811 in the X direction toward the front side in the feeding direction Df.

The component replenishment carriage 8 has two side wall plates 813 that are provided so as to stand vertically from both ends of the bottom plate 811 in the X direction. Each of the side wall plates 813 is attached to the bottom plate 811 in parallel to the feeding direction Df and the Z direction. Further, the component replenishment carriage 8 has a beam 814 extending in the X direction between the two side wall plates 813. The beam 814 is erected between the upper ends of the two side wall plates 813 at the rear ends of the two side wall plates 813.

The component replenishment carriage 8 further includes: casters 815 mounted to both ends of the lower surface of the bottom plate 811 in the X direction; and casters 815 attached to both sides in the X direction at the front end of the insertion plate 812 in the feeding direction Df, the casters 815 supporting the base plate 811 and the insertion plate 812 on the floor. Therefore, the component replenishment carriage 8 can move the caster 815 while rotating, according to an external force from an operator, an unmanned transport vehicle, or the like. In particular, the beam 814 functions as a handle, and the operator can move the element replenishment carriage 8 by operating the beam 814.

The component replenishment carriage 8 has two side plates 816 attached to the upper ends of the two side wall plates 813, respectively. Each side plate 816 protrudes from the side wall plate 813 toward the front side in the feeding direction Df. Further, a slit 817 extending in parallel to the feeding direction Df is provided at the front end of each side plate 816 in the feeding direction Df. Each slit 817 is open forward in the feeding direction Df and is disposed at the same height as the engaging

projections

719a, 719b of the feeder mount carriage 7.

The component replenishment carriage 8 has a unit attachment portion 83 disposed so as to be sandwiched between the two side plates 816, and the unit attachment portion 83 is supported by the two side plates 816. In the unit mounting portion 83, a plurality of unit slots 831 (set positions S) are arranged in the X direction, and the tape set unit 5 can be detachably mounted in each unit slot 831. The plurality of unit slots 831 are provided corresponding to the plurality of feeder slots 731 in the feeder mount carriage 7, respectively. In particular, as will be described later, in a state where the parts replenishment carriage 8 is mounted on the parts feeder mount carriage 7, one unit slot 831 and one parts feeder slot 731 which correspond to each other are positioned at the same position (placement position S) in the X direction.

The component replenishment carriage 8 further includes a reel table 85 disposed between the two side plates 816, and the reel table 85 is supported by the two side plates 816 on the rear side of the unit mounting portion 83 in the feeding direction Df. The spool mounting table 85 has a concave shape recessed downward, and has a front side swash plate 851 rising toward the front side at the front end and a rear side swash plate 852 rising toward the rear side at the rear end. The reel mounting table 85 further includes a mounting plate 853 provided between the front side inclined plate 851 and the rear side inclined plate 852 in the feeding direction Df, and the component supply reel 6 can be mounted on the mounting plate 853.

The component supply tape TP drawn out from the component supply reel 6 held on the reel table 85 can be held by the tape placing unit 5 attached to the unit mounting portion 83. As will be described later, the component replenishment carriage 8 is detachably attached to the feeder mounting carriage 7, and the reel table 85 holds the component supply reel 6 placed on the placement plate 853 at the upper holding position Lu (fig. 3) in a state where the component replenishment carriage 8 is attached to the feeder mounting carriage 7.

Fig. 7 to 10 are views showing the mounting operation of the component replenishment carriage to the feeder mounting carriage. In particular, fig. 7 is a side view showing a state before the component replenishment carriage 8 is mounted apart from the feeder mounting carriage 7, fig. 8 is a side view showing a state after the component replenishment carriage is mounted on the feeder mounting carriage, fig. 9 is a bottom view showing a state after the component replenishment carriage is mounted on the feeder mounting carriage, and fig. 10 is a perspective view showing a state after the component replenishment carriage is mounted on the feeder mounting carriage.

The mounting work is executed by moving the component replenishment carriage 8 to the feeder mounting carriage 7 from a state in which the two side plates 816 are opposed to the inside in the X direction of the two side plates 717 of the feeder mounting carriage 7 when viewed from the feeding direction Df (the state shown in fig. 4 to 7). As shown in fig. 7 to 8, the operation of the process until the component replenishment carriage 8 moves to the feeder mounting carriage 7 is as follows.

Each side plate 816 of the component supply cart 8 is positioned above the reel holding portion 75, and each side plate 816 passes above the reel holding portion 75 (and the component supply reel 6 held by the reel holding portion 75) as the component supply cart 8 moves toward the feeder mount cart 7. The insertion plate 812 of the component feeding cart 8 is positioned below the bottom plate 711 of the feeder mounting cart 7, and the insertion plate 812 is inserted between the bottom plate 711 and the floor.

In the Z direction, the width of each slit 817 of the component replenishment carriage 8 is the same as the width of the

engagement projections

719a, 719b (including play), and the slit 817 is engaged with (fitted onto) the engagement projection 719a and then engaged with (fitted onto) the engagement projection 719 b. Thus, the position of the side plate 816 of the component replenishment carriage 8 is restricted in the horizontal direction with respect to the position of the side plate 717 of the feeder mounting carriage 7, and is positioned.

In the X direction, the distance between the inner wall surfaces of the two side plates 717 of the feeder mount carriage 7 is the same as (including a play) the distance between the outer wall surfaces of the two side plates 816 of the component replenishment carriage 8, and the two side plates 816 of the component replenishment carriage 8 are engaged (fitted) between the two side plates 717 of the feeder mount carriage 7. Thus, the position of the unit mounting portion 83 of the component replenishment carriage 8 is restricted in the X direction with respect to the position of the feeder mounting portion 73 of the feeder mounting carriage 7 and is positioned. As described above, the plurality of unit slots 831 correspond to the plurality of feeder slots 731, respectively. Therefore, in the state of being positioned in the X direction, one unit slot 831 and one feeder slot 731, which correspond to each other (i.e., are located at the same placing position S), are opposed in the feeding direction Df.

As shown in fig. 9, two guide members 72 are provided on the bottom surface of the bottom plate 711 in front of the two casters 714 in the feeding direction Df, and these guide members 72 also serve a positioning function. That is, the two guide members 72 extend parallel to the feeding direction Df and face each other with an interval corresponding to the width of the insertion plate 812 in the X direction. Therefore, when the insertion plate 812 advancing forward in the feeding direction Df passes between the two casters 714 and is fitted between the two guide members 72, the two guide members 72 restrict the position of the insertion plate 812 from both sides in the X direction. Thus, the feeder mount carriage 7 and the component supply carriage 8 are positioned relative to each other in the X direction, and one unit slot 831 and one feeder slot 731, which correspond to each other, face each other in the feeding direction Df.

Then, finally, as shown in fig. 8 to 10, the bottom plate 811 of the component replenishment carriage 8 abuts against the bottom plate 711 of the feeder mounting carriage 7. In this way, the mounting operation of the component replenishment carriage 8 to the feeder mounting carriage 7 is completed.

In addition, unit replacement for replacing the tape placing unit 5 attached to the tape feeder 4 is performed in association with the above-described attachment work. Next, the structure of the tape placing unit 5 will be described, and then unit replacement will be described.

Fig. 11 is a perspective view showing the structure of the tape placing unit, fig. 12A is a side view showing the structure of the tape placing unit, fig. 12B is a cross-sectional view showing the structure of the tape placing unit, fig. 13 is a plan view showing the structure of the tape placing unit, and fig. 14 is a front view showing the structure of the tape placing unit.

The tape placing unit 5 includes: a base frame 51; a support frame 52 facing the base frame 51 from above; and a plurality of (two) compression coil springs 53 disposed between the base frame 51 and the support frame 52. The plurality of compression coil springs 53 are arranged in line in the feeding direction Df, and apply a biasing force (elastic force) to the base frame 51 and the support frame 52 to separate the base frame 51 and the support frame 52 from each other in the Z direction.

The base frame 51 has a susceptor main body 511 extending in the feeding direction Df. The susceptor main body 511 has a bottom surface 511a formed flat. Further, the base frame 51 includes: an upward extension portion 512 extending upward from the front end of the susceptor main body 511 in the feeding direction Df; and a front projection 513 projecting forward in the feeding direction Df from an upper end of the upper extension 512. The susceptor frame 51 further includes a side wall plate 514 extending in the feeding direction Df at one end in the X direction of the upper surface of the susceptor main body 511. The sidewall plate 514 protrudes upward from the base main body 511.

The support frame 52 has a support main body 521 extending in the feeding direction Df. The support body 521 faces the base body 511 of the base frame 51 from above, and the support body 521 overlaps the base body 511 when viewed from above. The support body 521 has a horizontally formed tape mounting portion 521a on the upper surface thereof, and the component supply tape TP can be mounted on the tape mounting portion 521 a. That is, the support frame 52 supports the component supply tape TP placed on the tape placing portion 521a of the support main body 521. Further, the support main body 521 is provided with an engagement hole 521b penetrating in the X direction.

Further, the support frame 52 includes: a downward extending portion 522 extending downward from the front end of the support main body 521 in the feeding direction Df; and a rear protrusion 523 protruding rearward in the feeding direction Df from a lower end of the lower extension 522. The rear projection 523 of the support frame 52 faces the front projection 513 of the base frame 51 from below. Further, the support frame 52 includes: a downward extending portion 524 extending downward from the rear end of the support main body 521 in the feeding direction Df; and a rear protrusion 525 protruding rearward in the feeding direction Df from a lower end of the lower extension 524.

The tape placing unit 5 further includes a rear frame 54 disposed behind the base main body 511. The rear frame 54 has a rear body 541 mounted to the rear end of the base body 511 in the feeding direction Df. The rear body 541 extends in the Z direction and protrudes upward from the base body 511, and a bottom surface 541a of the rear body 541 and the bottom surface 511a of the base body 511 are included in the same plane (i.e., coplanar). The rear frame 54 also has a front projection 542 projecting forward in the feeding direction Df from the upper end of the rear body 541. The front projection 542 of the rear frame 54 faces the rear projection 525 of the support frame 52 from above.

The plurality of compression coil springs 53 are disposed between the upper extension portion 512 of the base frame 51 and the lower extension portion 524 of the support frame 52 in the feeding direction Df. The lower end of each compression coil spring 53 abuts against the upper surface of the base main body 511 of the base frame 51, and the upper end of each compression coil spring 53 abuts against the lower surface of the support main body 521 of the support frame 52. Therefore, the support frame 52 is biased in a direction (Z direction) away upward from the base frame 51 by the compression coil springs 53. On the other hand, the front projection 513 and the front projection 542 face the rear projection 523 and the rear projection 525 provided on both sides of the support frame 52 in the feeding direction Df from above, respectively. Therefore, in a state where no external force against the urging force of each compression coil spring 53 is applied, the rear projection 523 and the rear projection 525 of the support frame 52 abut against the front projection 513 and the front projection 542 respectively by the urging force of each compression coil spring 53, and the support frame 52 is stationary with respect to the base frame 51 at the uppermost point.

Further, each compression coil spring 53 is externally fitted to a support rod 531 projecting upward from the upper surface of the base main body 511. The support rod 531 extends parallel to the Z direction and is attached to the upper surface of the base main body 511. On the other hand, the support main body 521 is provided with an insertion hole into which the support rod 531 can be inserted in the Z direction, and the support rod 531 enters the insertion hole of the support main body 521 as the base frame 51 and the support frame 52 approach each other.

The tape placing unit 5 includes a lever 55 rotatably attached to the side wall plate 514 of the base frame 51. The lever 55 has a lever frame 551 disposed between the side wall plate 514 and the support frame 52 in a plan view. A long hole 551a penetrates through the tip end portion of the lever frame 551 in the X direction, a bolt 56 having a head larger than the width of the long hole 551a is inserted into the long hole 551a from the opposite side of the side wall plate 514, and the bolt 56 is screwed to the side wall plate 514. In this way, the lever 55 is attached to the side wall plate 514 so as to be rotatable about the bolt 56 (rotation axis) parallel to the X direction. The lever 55 has an engaging projection 552 projecting in the X direction from the lever frame 551. The engaging projection 552 is inserted into the engaging hole 521b of the support frame 52.

The lever 55 also has a belt cover 553 attached to the rear end of the lever frame 551 in the feeding direction Df. The belt cover 553 includes: a side wall plate 553a extending upward from the rear end of the rod frame 551 in the feeding direction Df; an abutting plate 553b extending in the X direction from the side wall plate 553a toward the opposite side of the side wall plate 514; and a sidewall plate 553c extending downward from an end of the abutment plate 553b opposite to the sidewall plate 514. The abutment plate 553b spans the rear end of the support frame 52 and the front end of the rear frame 54 in the X direction, and the sidewall plate 553a and the sidewall plate 553c are located on both sides of the rear end of the support frame 52 and the front end of the rear frame 54 in the X direction. The belt cover 553 has an abutting portion 553d that protrudes inward from the front end of the sidewall plate 553a (i.e., toward the sidewall plate 553 c).

The tape placing unit 5 has a bracket 57 disposed behind the rear frame 54. The bracket 57 has a bracket main body 571 attached to the rear end of the rear frame 54 in the feeding direction Df. The bracket main body 571 is erected in the Z direction and protrudes upward from the rear frame 54, and a bottom surface 571a of the bracket main body 571 and a bottom surface 541a of the rear main body 541 are included in the same plane (i.e., coplanar).

The bracket 57 further includes a unit engaging protrusion 572 provided at the upper end of the bracket main body 571. The unit engaging projection 572 is located at the uppermost portion of the tape placing unit 5. The unit engaging projection 572 includes: an upward extending portion 572a extending upward from the upper end of the bracket main body 571; and

flanges

572b, 572c protruding from the upper end of the upward extending portion 572a to both sides in the X direction, and the unit engaging projection 572 is configured in a T shape when viewed from the feeding direction Df. These

flanges

572b and 572c extend in the feeding direction Df, respectively.

The bracket 57 has a unit engagement hole 573 provided at the lower end of the bracket main body 571. The unit engagement hole 573 includes: an upward extending hole 573a extending upward from the lower end of the bracket body 571; and

grooves

573b, 573c that project from the upper end of the upward extension setting hole 573a to both sides in the X direction, and the unit engagement hole 573 is configured in a T shape when viewed from the feeding direction Df. These

grooves

573b, 573c extend in the feeding direction Df. The unit engagement holes 573 are open on both sides (front and rear sides) in the feeding direction Df. The unit engagement hole 573 and the unit engagement projection 572 have the same shape and size when viewed in the feeding direction Df, and they are congruent.

The bracket 57 further has a belt introduction hole 574 penetrating the bracket main body 571 in the feeding direction Df. This constitutes a tape introduction path extending from the tape introduction hole 574 to the tape loading portion 521a of the support frame 52 via the upper surface of the rear frame 54. Next, a tape placing operation for holding the component feeding tape TP by the tape placing unit 5 will be described.

Fig. 15 is a perspective view showing a first step of the tape placing operation to the tape placing unit, fig. 16A is a side view showing the first step of the tape placing operation to the tape placing unit, fig. 16B is a cross-sectional view showing the first step of the tape placing operation to the tape placing unit, fig. 17 is a perspective view showing a second step of the tape placing operation to the tape placing unit, fig. 18A is a side view showing the second step of the tape placing operation to the tape placing unit, fig. 18B is a cross-sectional view showing the second step of the tape placing operation to the tape placing unit, fig. 19A is a side view showing a third step of the tape placing operation to the tape placing unit, and fig. 19B is a cross-sectional view showing the third step of the tape placing operation to the tape placing unit. In addition, the tape placing work is performed by the operator.

As shown in fig. 15, 16A, and 16B, in the first step of the tape placing operation, the component supply tape TP is placed on the tape placing portion 521a of the support frame 52. In fig. 15, 16A, and 16B, only a part of the component supply tape TP (the vicinity of the tape mounting portion 521 a) is shown. The component supply tape TP is loaded by inserting the leading end of the component supply tape TP into the tape introduction hole 574 from the rear in the feeding direction Df and introducing the component supply tape TP to the tape loading portion 521 a. At this time, the support frame 52 rises relative to the base frame 51 to the uppermost point where the rear projection 523 and the rear projection 525 of the support frame 52 abut against the front projection 513 and the front projection 542, respectively. Therefore, the lever 55 engaged with the engagement hole 521b of the support frame 52 via the engagement projection 552 is stationary in a state rotated upward as the support frame 52 ascends to the uppermost point.

As shown in fig. 17, 18A and 18B, in the second step of the tape placing operation, the worker depresses the tape cover 553 of the lever 55 against the urging force of each compression coil spring 53. Thereby, the rod 55 rotates downward, and the support frame 52 is pressed by the rod 55 via the engaging projection 552 engaged with the engaging hole 521b, and moves downward. Then, when the lower portion of the lever 55 abuts against the base frame 51, the rotation of the lever 55 is stopped. In this state, the extending direction of the long hole 551a is parallel to the feeding direction Df. The tape cover 553 covers the component supply tape TP from the tape introduction hole 574 to the tape loading portion 521 a. Specifically, the abutment plate 553b of the tape cover 553 abuts the upper surface of the component supply tape TP to restrain the component supply tape TP (tape restraining state). The movement of the component feeding tape TP is prevented by this tape restraining state. The

side wall plates

553a and 553b of the tape cover 553 sandwich the component supply tape TP from the X direction.

In the third step of the tape placing operation, the operator pushes the lever 55, which has stopped rotating, forward in the feeding direction Df. That is, since the rod 55 is screwed to the bolt 56 via the elongated hole 551a, the rod 55 can be displaced in the feeding direction Df with respect to the bolt 56 in a state where the elongated hole 551a is parallel to the feeding direction Df. In addition, in the third step, the rotation of the rod 55 can be restricted against the urging force of the compression coil spring 53. That is, as shown in fig. 19A and 19B, the front projection 551B projects forward from the front end of the rod frame 551 of the rod 55 in the feeding direction Df. On the other hand, a limiting plate 554 having a predetermined thickness is disposed at a front end portion of the upper surface of the base frame 51. As will be described later, the front projection 551b of the lever 55 functions as a rotation restriction key, and the restriction plate 554 functions as a rotation restriction stopper, and the rotation of the lever 55 is restricted by the contact (engagement) of the front projection 551b with the restriction plate 554.

As shown in fig. 18B, before the rotation of the lever 55 is stopped and the operator pushes out the lever 55, the bolt 56 contacts the front end of the elongated hole 551a in the feeding direction Df, and the lever 55 is located at a retracted position Le1 where the front projection 551B of the lever 55 is retracted from the regulating plate 554 to the rear in the feeding direction Df. In a state where the lever 55 is located at the retracted position Le1, the lever 55 can rotate. On the other hand, as shown in fig. 19B, after the operator pushes out the lever 55, the lever 55 is located at a contact position Lc at which the bolt 56 contacts the rear end of the elongated hole 551a in the feeding direction Df and the front projection 551B of the lever 55 contacts the upper surface of the regulating plate 554. In a state where the lever 55 is located at the contact position Lc, the downward movement of the front projection 551b accompanying the rotation of the lever 55 is restricted by the restriction plate 554 contacting the front projection 551b from below. That is, the rotation of the lever 55 is restricted by the restricting plate 554.

In this way, the tape placing unit 5 holding the component supply tape TP can be attached to the tape feeder 4 (fig. 20A, 20B, and 21). Fig. 20A is a side view showing a state of the tape placing unit when mounted on the tape feeder, fig. 20B is a side view showing a state of the tape placing unit when mounted on the tape feeder, and fig. 21 is a perspective view showing a state of the tape placing unit mounted on the tape feeder. As shown in fig. 20B, when the tape placing unit 5 is attached to the tape feeder 4, the lever 55 is returned to the rear in the feeding direction Df with respect to the regulating plate 554 by a function of a lever release boss 41e (fig. 25B, 27B, 29B, and the like) described later, and is retracted from the contact position Lc to the retracted position Le 2. The front projection 551b of the lever 55 located at the retracted position Le2 is retracted from the regulating plate 554 to the rear side in the feeding direction Df. Thereby, the lever 55 can be rotated by the urging force of the compression coil spring 53, and the belt-restrained state is released.

The retracted position Le2 is located between the contact position Lc and the retracted position Le1 in the feeding direction Df, in other words, behind the contact position Lc and in front of the retracted position Le 1. Fig. 20B shows a state immediately before the lever 55 rotatable at the retracted position Le2 is rotated, in which a gap Δ is left between the front end (right end in fig. 20B) of the long hole 551a in the feeding direction Df and the bolt 56. As described later, the gap Δ is provided to secure a movement amount of the tape placing unit 5 (more specifically, a member of the tape placing unit 5 other than the rod 55) necessary for pushing the tape placing unit 5 attached to the tape feeder 4 to the front side in the feeding direction Df and detaching from the tape feeder 4, and corresponds to a distance between the retracted position Le1 and the retracted position Le 2. In this way, in a state where the tape placing unit 5 is attached to the tape feeder 4, the lever 55 is located at the retracted position Le2, and a gap Δ is secured between the tip of the elongated hole 551a and the bolt 56.

As shown in fig. 21, a feeder engagement hole 412 is provided at the rear end of the carriage 411 of the belt feeder 4 in the feeding direction Df. Specifically, the bracket 411 includes: a bracket main body 411a having a rectangular parallelepiped shape extending in the feeding direction Df; and a tray protruding portion 411b protruding downward from the tray main body 411a at the rear end of the tray main body 411a in the feeding direction Df. The feeder engaging hole 412 is provided so as to penetrate the tray protrusion 411b in the feeding direction Df, and thereby opens at both ends of the tray protrusion 411b in the feeding direction Df. The feeder engagement hole 412 includes: an upwardly extending hole 412a extending upward from the lower end of the bracket 411; and

grooves

412b and 412c protruding from the upper end of the upward extending installation hole 412a to both sides in the X direction, and the feeder engagement hole 412 is formed in a T shape. These

grooves

412b, 412c extend in the feeding direction Df. The feeder engagement hole 412 is open on both sides (front and rear sides) in the feeding direction Df. The feeder engagement hole 412 and the unit engagement projection 572 have the same shape and size when viewed in the feeding direction Df, and are identical. Therefore, the operator can mount the tape placing unit 5 on the tape feeder 4 by inserting the unit engaging projection 572 of the tape placing unit 5 holding the component supply tape TP into the feeder engaging hole 412 of the tape feeder 4 from the rear in the feeding direction Df. In the tape placing unit 5 in which the unit engaging projection 572 is engaged with the feeder engaging hole 412 at the engaging position Lg (that is, the tape placing unit 5 attached to the tape feeder 4), the lever 55 is positioned at the retracted position Le2 as described above.

As described above, the component replacement can be performed using the component replenishment carriage 8 in accordance with the attachment of the subsequent tape placement unit 5 to the tape feeder 4, and the detachment of the previous tape placement unit 5 from the tape feeder 4 is performed during the component replacement.

Fig. 22 is a perspective view showing a preparation operation performed by an operator for unit replacement on the component supply cart, fig. 23A is a partial horizontal cross-sectional view showing a lock mechanism provided in the component supply cart, fig. 23B is a partial vertical cross-sectional view showing a lock mechanism provided in the component supply cart, and fig. 23C is a view schematically showing a lock mechanism provided in the component supply cart in a vertical cross-section. Fig. 23C is a schematic view, and is different from fig. 23A, 23B and the like in a dimensional relationship. As described above, in the unit mounting portion 83 of the component replenishment carriage 8, the plurality of unit insertion grooves 831 are aligned in the X direction. Each unit insertion slot 831 is a T-shaped engagement protrusion having the same shape and size as the unit engagement protrusion 572, and an operator can attach the tape loading unit 5 to the unit insertion slot 831 by inserting the unit engagement hole 573 of the tape loading unit 5 into the unit insertion slot 831 from the feeding direction Df.

The component replenishment carriage 8 has a lock mechanism 87 shown in fig. 23A to 23C. The lock mechanism 87 includes: a plurality of locking keys 871 respectively provided corresponding to the plurality of unit insertion grooves 831; and a rod 873 extending in the X direction, the plurality of locking keys 871 being attached to the rod 873. The rod 873 is supported movably in the X direction with respect to the unit mounting portion 83, and the operator can move the rod 873 in the X direction by operating a catch 875 provided at one end of the rod 873 in the X direction, thereby switching between an "unlocked state" and a "locked state" shown in fig. 23A to 23C.

The unit insertion slot 831 has: an upper extension portion 831a provided to extend in the Z direction; and

flanges

831b and 831c protruding from the upper end of the upper extension portion 831a to both sides in the X direction, the unit insertion slot 831 being configured into a T shape when viewed from the feeding direction Df. These

flanges

831b, 831c extend in the feed direction Df. The upper extension portion 831a is partially hollow, and the unit insertion slot 831 has a hollow portion 831d in the upper extension portion 831 a. The hollow 831d is open downward and on one side in the X direction. In contrast, the rod 873 extends in the X direction below the bracket 57 of the tape placing unit 5 attached to the unit insertion slot 831, and the lock key 871 extends from the rod 873 into the hollow 831d via the opening below the hollow 831 d.

The tray 57 of the tape placement unit 5 has a hollow portion 575 therein, and in a state where the tray 57 of the tape placement unit 5 is attached to the unit insertion slot 831, the hollow portion 575 of the tray 57 and the hollow portion 831d of the unit insertion slot 831 are adjacent to each other in the X direction and communicate with each other. In the "unlocked state", the lock key 871 is accommodated in the upper extension portion 831a and retracted from the hollow portion 575. Therefore, the tape placing unit 5 can be detached from the unit insert slot 831. On the other hand, in the "locked state", the lock key 871 protrudes from the upper extension setting portion 831a toward the hollow portion 575. As a result, the lock key 871 engages with the hollow 575 of the tape loading unit 5, and the removal of the tape loading unit 5 from the unit insertion slot 831 is prohibited.

Therefore, when the tape placement unit 5 is attached to the unit insertion slot 831, the operator appropriately operates the handle 875 to retract the lock key 871 from the hollow portion 575 (unlocked state), and inserts the unit engagement hole 573 of the tape placement unit 5 into the unit insertion slot 831. Next, the operator operates the handle 875 to engage the lock key 871 with the hollow portion 575 of the tape placing unit 5 (locked state).

In fig. 22, the component supply tape TP is omitted, but the worker mounts the tape placement unit 5 holding the component supply tape TP drawn out from the component supply reel 6 in the unit insertion slot 831. Therefore, the operator places the component supply reel 6 on the reel table 85, and the component supply tape TP held by the tape placing unit 5 attached to the unit insertion slot 831 is wound around the component supply reel 6. Thus, the preparation operation for the component replenishment carriage 8 is completed. In fig. 22, a case is shown in which the pair of tape placing units 5 and the component supply reels 6 are placed on the component supply cart 8, but an operator can place the plurality of pairs of tape placing units 5 and the component supply reels 6 on the component supply cart 8 as appropriate.

Fig. 24 to 32C are diagrams showing operations performed in association with unit replacement. In these figures, the preceding tape placing unit 5 attached to the tape feeder 4 before replacement is referred to as a tape placing unit 5A, and the subsequent tape placing unit 5 attached to the tape feeder 4 after replacement is referred to as a tape placing unit 5B. In order to clearly show the state of the tape placing unit 5 in the range hidden by the side wall of the tape feeder 4, the side wall is appropriately shown in a see-through manner. As shown in fig. 22, this unit replacement is performed by attaching the component feeding carriage 8, to which the tape placing unit 5 and the component supply reel 6 are attached, to the feeder mounting carriage 7 in the same manner as the above-described attaching operation.

At the start time of the mounting operation, the unit engaging projection 572 of the preceding tape placing unit 5A is located at the engaging position Lg at which the tape feeder engaging hole 412 of the tape feeder 4 is engaged (i.e., the position of the feeder engaging hole 412), and the preceding tape placing unit 5A is mounted on the carriage 411 of the tape feeder 4 (fig. 21 and 24). As shown in fig. 25B, the belt feeder 4 is provided with a support boss 4e (support portion), and the belt placing unit 5 is provided with a support slit 5e (supported portion) that opens forward in the feeding direction Df, and the support slit 5e is engaged (fitted to) the support boss 4e from the rear side in the feeding direction Df. That is, the support bosses 4e of the tape feeder 4 support the tape placing unit 5 (preceding tape placing unit 5A) attached to the tape feeder 4 by engaging with the support slits 5e of the tape placing unit 5. In this way, the tape placing unit 5 attached to the tape feeder 4 (feeder body 41) can be firmly supported by the support bosses 4 e. From this state, the subsequent tape placing unit 5B mounted on the component replenishment carriage 8 moves in the feeding direction Df toward the engagement position Lg in association with the mounting operation (fig. 24 to 26). Then, the leading end of the subsequent tape placing unit 5B comes into contact with the trailing end of the preceding tape placing unit 5A (fig. 27A, 27B).

The feeder body 41 of the tape feeder 4 has a lever release boss 41 e. In contrast, when the preceding tape placing unit 5A is mounted on the tape feeder 4, the lever 55 of the tape placing unit 5A abuts against the lever release boss 41e, and is pushed rearward with respect to the regulating plate 554 by the lever release boss 41 e. Thereby, the state of the tape placing unit 5 shifts from the state of fig. 18B described above to the state of fig. 20B. Therefore, the preceding tape placing unit 5A shown in fig. 25B is in the state of fig. 20B.

When the subsequent tape placing unit 5B in contact with the preceding tape placing unit 5A is further advanced to the front side, the preceding tape placing unit 5A is pushed out to the front side. However, the lever 55 of the preceding tape placing unit 5A abuts on the lever release boss 41e, and the movement of the front side of the lever release boss 41e is restricted by the lever release boss 41 e. Therefore, in the state where the lever 55 is retained, the member other than the lever 55 in the preceding tape placing unit 5A moves forward, and the unit engaging projection 572 of the preceding tape placing unit 5A is pulled out forward (retreated from the engaging position Lg) from the feeder engaging hole 412. The gap Δ between the tip of the elongated hole 551a and the bolt 56 is set to be equal to or greater than the distance by which the unit engaging projection 572 moves to pull the unit engaging projection 572 out of the feeder engaging hole 412.

When the subsequent tape placing unit 5B moves in the feeding direction Df in this way, the preceding tape placing unit 5A is pushed out by the subsequent tape placing unit 5B, and the unit engaging projection 572 of the preceding tape placing unit 5A is retracted from the engaging position Lg forward in the feeding direction Df and is pulled out of the feeder engaging hole 412 (fig. 28A and 28B). As a result, the preceding tape placing unit 5A is detached from the carriage 411 of the tape feeder 4 and falls by its own weight (fig. 28A to 30B). Specifically, when the unit engaging projection 572 of the preceding tape placing unit 5A is pulled out forward in the feeding direction Df from the feeder engaging hole 412, the rear end of the preceding tape placing unit 5A falls while rotating about the support boss 4e in a state where the support slit 5e of the preceding tape placing unit 5A is engaged with the support boss 4e (fig. 28B). Then, as the preceding tape placing unit 5A falls, the support slit 5e of the preceding tape placing unit 5A is disengaged from the support boss 4e of the tape feeder 4. In this way, the preceding tape placing unit 5A is detached from the tape feeder 4. The preceding tape placing unit 5A that has been detached is in the state of fig. 12B.

As described above, the feeder body 41 of the tape feeder 4 has the lever release boss 41e, and the abutting portion 553d located at the tip of the tape cover 553 attached to the preceding tape placing unit 5A of the feeder body 41 abuts against the lever release boss 41 e. On the other hand, as described above, the rod 55 is attached to the base frame 51 by the bolt 56 inserted into the elongated hole 551 a. Therefore, in the above-described process in which the preceding tape placing unit 5A is pushed out by the subsequent tape placing unit 5B, the preceding tape placing unit 5A (a member other than the rod 55 thereof) moves in the feeding direction Df in a state in which the movement of the rod 55 of the preceding tape placing unit 5A in the feeding direction Df is obstructed by the feeder body 41, and the tape restraining state of the preceding tape placing unit 5A is continuously released.

Next, as shown in fig. 31, the unit engaging projection 572 of the subsequent tape placing unit 5B enters the engaging position Lg from the rear in the feeding direction Df. At this time, the subsequent tape placing unit 5B maintains the tape restraining state until the subsequent tape placing unit 5B is mounted to the carriage 411 of the tape feeder 4. On the other hand, as shown in fig. 31, as the unit engaging projection 572 of the subsequent tape placing unit 5B enters the engaging position Lg, the abutting portion 553d of the tape cover 553 of the lever 55 provided in the subsequent tape placing unit 5B abuts against the lever release boss 41e of the feeder body 41. Then, (components other than the rod 55 of) the tape placing unit 5 moves in the feeding direction Df in a state where the movement of the rod 55 in the feeding direction Df is obstructed by the feeder body 41. Therefore, the rod 55 is pushed out relatively by the feeder body 41 from the contact position Lc to the retracted position Le2, and the front projection 551B of the feeder body 41 is disengaged from the regulating plate 554 (fig. 32B). As a result, the lever 55 is rotated upward by the urging force of the compression coil spring 53, the tape restraining state is released, the component supply tape TP is pressed against the sprocket 44, the hole of the component supply tape TP is fitted to the teeth of the sprocket 44, and the component supply tape TP can be fed in the feeding direction Df. In this way, the unit engagement projection 572 of the subsequent tape placing unit 5B engages with the feeder engagement hole 412 at the engagement position Lg, and the subsequent tape placing unit 5B is attached to the carriage 411 of the tape feeder 4 (fig. 32A and 32B), thereby completing the unit replacement. As shown in fig. 32C, when the component supply cart 8 is pulled out from the feeder mount cart 7 in the feeding direction Df to the rear, the subsequent tape placing unit 5B mounted on the tape feeder 4 is detached from the component supply cart 8 and remains on the tape feeder 4.

Fig. 33 is a block diagram showing a configuration of a component mounting system including the component mounting machine. In fig. 33, the component replenishment carriage 8 removed from the component supply section 25 of the component mounting machine 1 is shown separately from the component mounting machine 1. The component mounting system 9 includes the component mounting apparatus 1 and the component replenishment support device 91. Here, an electrical configuration of the component mounting system 9 will be mainly described with reference to fig. 33.

As shown in fig. 33, the tape feeder 4 has a tape sensor 491. The tape sensor 491 detects the component feeding tape TP attached to an attachment portion 441 (fig. 2 and 3) between the tape placing unit 5 engaged with the carriage 411 and the sprocket 44. Further, the feeder mount carriage 7 has a reader 78 that reads the supply carriage ID86 attached to the component supply carriage 8. The replenishment carriage ID86 is made up of a barcode and is unique, and can be used to individually identify the component replenishment carriage 8 to which the replenishment carriage ID86 is attached. The reader 78 is attached to a position facing the supply carriage ID86 of the component supply carriage 8 in a state where the component supply carriage 8 is attached to the feeder mount carriage 7. That is, the reader 78 reads the replenishment carriage ID86 by scanning the replenishment carriage ID86 of the component replenishment carriage 8 attached to the feeder mount carriage 7. The configuration of the replenishment carriage ID86 and the reader 78 is not limited to this example, and may be, for example, an RFID (Radio Frequency Identifier).

The component mounting apparatus 1 further includes a control unit 101, a storage unit 102, and a communication unit 103. The control Unit 101 is a processor including, for example, a CPU (Central Processing Unit), and executes overall control of the component mounting apparatus 1. The storage unit 102 is constituted by, for example, an HDD (Hard Disk Drive), and stores component feeder information Ipf and the like described later. The communication unit 103 performs communication between the component mounting apparatus 1 and the component replenishment support apparatus 91. Similarly, the component replenishment carriage 8 also includes a communication unit 803 that performs communication between the component replenishment carriage 8 and the component replenishment support device 91.

The component replenishment support device 91 includes a calculation unit 911, a storage unit 912, a communication unit 913, and a user interface 914, and is configured by, for example, a personal computer. The arithmetic unit 911 is a processor composed of, for example, a CPU, and plays a role of arithmetic operations in the component replenishment support device 91. The storage unit 912 is formed of, for example, an HDD, and stores component correspondence information Ip and feeder correspondence information If, which will be described later. The communication unit 913 executes communication with the control unit 101 of the component mounting apparatus 1 and communication with the communication unit 803 of the component replenishment carriage 8. The user interface 914 is configured by an input device such as a mouse or a keyboard, and a display device such as a display. The component replenishment support device 91 further includes a reader 915 which reads the feeder ID421, the reel ID63, the component ID64, and the like. The specific configuration of the component replenishment support device 91 is not limited to this example, and may be a portable tablet terminal, for example.

The component replenishment support device 91 provided in the component mounting system 9 functions to support component replenishment to the tape feeder 4 by using the component replenishment carriage 8. In particular, the component replenishment support device 91 can support the operation of collectively performing component replenishment on a plurality of replenishment target tape feeders 4 that are targets of component replenishment among the plurality of tape feeders 4 of the component supply unit 25. This point will be explained below.

As shown in step S13 of fig. 2, when the component supply tape TP attached to the attachment location 441 of the tape feeder 4 is loaded and the tip end of the component supply tape TP is fed out to the sprocket 44, the unit replacement (attachment work) shown in fig. 24 to 32C can be performed. In this specification, the case where the component supply tape TP for component supply is attached to the attachment portion 441 after the component supply tape TP for component supply is attached to the attachment portion 441 by such unit replacement is referred to as "preset", and a period from a time point at which the component supply tape TP attached to the attachment portion 441 of the tape feeder 4 is engaged with the sprocket 44 by loading until the component of the component supply tape TP runs out is referred to as "presettable period".

When all the tape feeders 4 of the automatic loading type mounted on one component supply unit 25 reach the presettable period, the component supply reel 6 on which the component supply tape TP for component supply by these tape feeders 4 is wound is transferred from the reel mounting table 85 of the component supply cart 8 to the reel holding unit 75 of the feeder mounting cart 7, whereby the component supply cart 8 can be detached from the feeder mounting cart 7. In addition, with the component feeding cart 8 detached, the tape placing unit 5 engaged with the tape feeder 4 is disengaged from the unit insertion slot 831 of the component feeding cart 8, and stays in a state engaged with the tape feeder 4. As a result, for example, as shown in fig. 24, the state of the feeder mounting carriage 7 before the component replenishment carriage 8 is mounted, that is, the state in which the component supply reel 6 on which the component supply tape TP mounted to the mounting portion 441 of the tape feeder 4 is wound is held by the feeder mounting carriage 7 is realized.

Therefore, the operator can collectively perform component replenishment (collectively replenishment) by simultaneously performing the unit replacement shown in fig. 24 to 32C for the tape feeders 4 that have reached the presettable period. In particular, in the present embodiment, the component replenishment support device 91 supports the component replenishment support so that the operator can prepare the component replenishment carriage 8 for the batch replenishment of the components before the batch replenishment of the components.

Fig. 34 is a flowchart showing an example of component replenishment support performed by the component replenishment support apparatus. The flowchart is executed by the calculation of the calculation unit 911 of the component replenishment support apparatus 91.

In step S101, the calculation unit 911 obtains a production plan for producing a substrate B (component-mounted substrate) on which components are mounted by using the component mounting apparatus 1, and stores the production plan in the storage unit 912. The production plan is acquired by, for example, an input operation performed by an operator via the user interface 914. Specifically, the production plan indicates the type of substrate to be produced in association with the number of sheets. The calculation unit 911 obtains the progress status (production progress) of the production plan from the component mounting apparatus 1 (step S102). That is, the type and number of substrates already produced at the current point in time in the production plan, in other words, the substrate up to which type of the first substrate has already been produced at the current point in time is obtained as the progress status. Further, the arithmetic unit 911 acquires the board data for controlling the component mounter 1 based on the production plan from the component mounter 1 (step S103). The substrate data is a program for controlling the component mounter 1 to mount components on the substrate B in the order according to the production plan, and the control unit 101 of the component mounter 1 controls the operations of the conveyor 12, the tape feeder 4, the mounting head 31, and the like based on the substrate data to mount components on the substrate B.

In step S104, the supply part number Nc for identifying the plurality of (4 in the example of fig. 1) component supply parts 25 of the component mounting machine 1 is reset to 0, and in step S105, the supply part number Nc is incremented. In step S106, the feeder number Nf identifying each of the tape feeders 4 mounted to the component supply unit 25 corresponding to the current supply unit number Nc (where Nc is 1) is reset to 0, and in step S107, the feeder number Nf is incremented.

Then, in step S108, it is determined whether or not the tape feeder 4 of the feeder number Nf in the component supply unit 25 of the supply unit number Nc, that is, the target tape feeder 4 is the tape feeder 4 of the automatic loading type. When the target tape feeder 4 is of the automatic loading type (yes in step S108), the time until the target tape feeder 4 reaches the preset period is calculated based on the production progress and the substrate data (step S109), and the process proceeds to step S110. Specifically, the time is calculated from the result of simulation of the situation where the tape feeder 4 as the object supplies components based on the substrate data, starting from the current production progress.

That is, as exemplified in fig. 9 and the like of WO2018/135446, the production plan acquired by the calculation unit 911 indicates the number of produced substrates and the production order for each type of substrate, and indicates the number of components required to produce one substrate of that type for each component name. The calculation unit 911 can acquire the cycle time, which is the time required for the component mounting machine 1 to mount all the components on one substrate when the production plan is executed according to the substrate data. The calculation unit 911 stores the remaining number of components on the component supply tape TP held at the reel ID63 in the storage unit 912 in association with the reel ID 63. Therefore, the timing at which the one component supply tape TP runs out of components and the next component supply tape TP is loaded, that is, the start time of the preset period can be calculated based on the remaining number of components in the one component supply tape TP used for component supply by the tape feeder 4 as the target, the number of components mounted on one substrate, and the cycle time.

On the other hand, when the target tape feeder 4 is not of the automatic loading type (no in step S108), the process proceeds to step S110 without going through step S109.

In step S110, the time until the remaining number of warnings is calculated. Specifically, the time until the number of components (i.e., the remaining number of components) accommodated in all the component supply tapes TP mounted on the target tape feeder 4 reaches the warning remaining number is calculated based on the production progress and the substrate data as described above. The warning remaining number provides a timing for warning the operator, and the component mounting apparatus 1 notifies the operator of the warning when the remaining number of components in the tape feeder 4 reaches the warning remaining number.

In step S111, the time until the remaining number stops is calculated. Specifically, the time until the remaining number of components of the target tape feeder 4 reaches the stop remaining number is calculated based on the production progress and the substrate data as described above. Further, the stop remaining number is a value smaller than the warning remaining number, and a timing of stopping the component supply by the tape feeder 4 is provided, and when the remaining number of components of the tape feeder 4 reaches the stop remaining number, the component mounting machine 1 stops the component supply by the tape feeder 4.

In step S112, the time until the feeder mount carriage 7 is replaced is calculated. That is, when the type of substrate to be produced according to the production plan changes, the layout is changed. Therefore, the time until the schedule is changed is calculated.

In step S113, it is checked whether the feeder number Nf reaches the maximum value Nfx (corresponding to the number of tape feeders 4 in the supply section number Nc), and steps S107 to S112 are executed until the feeder number Nf reaches the maximum value Nfx. Thus, steps S107 to S112 are executed for all the tape feeders 4 of the component supply unit 25 of the supply unit number Nc.

In step S114, it is checked whether or not the supply part number Nc has reached the maximum value Ncx (corresponding to the number of supply part numbers Nc in the component mounting apparatus 1), and steps S105 to S113 are executed until the supply part number Nc has reached the maximum value Ncx. Thus, steps S105 to S113 are executed for all the component supply units 25 of the component mounting apparatus 1.

Incidentally, a description is given here of a component mounting machine 1. However, in a production line in which a plurality of component mounters 1 are arranged in series, when the board B is sequentially conveyed to the plurality of component mounters 1 and the component mounters 1 execute component mounting on the board B, steps S102 to S114 are executed for each of the plurality of component mounters 1. In addition, when each component mounting apparatus 1 has a plurality of lanes (for example, two lanes), steps S102 to S114 are executed for the plurality of lanes, respectively. When a plurality of production lines are provided, steps S101 to S114 are executed for each of the plurality of production lines.

In step S115, the calculation unit 911 calculates a schedule based on the calculation results in steps S101 to S114. The schedule shows the occurrence timing of each event of the tape feeder 4 calculated in steps S109 to S112 for each tape feeder 4, for example, a presettable period of the tape feeder 4 of the automatic loading type for each tape feeder 4.

In step S116, the calculation unit 911 calculates the timing of replenishment of the components to the tape feeder 4. In particular, the calculation unit 911 determines the timing at which the above-described collective replenishment can be executed for each of the plurality of component supply units 25. Specifically, a period in which the presettable periods of the plurality of tape feeders 4 of the automatic loading type included in the component supply unit 25 overlap is calculated as a collectively replenishable period (replenishment timing). The collective replenishment period corresponds to a period in which all the component supply reels 6 held by the component replenishment carriage 8 of the feeder mount carriage 7 mounted on the component supply unit 25 are transferred from the component replenishment carriage 8 to the feeder mount carriage 7, and the component replenishment carriage 8 can be removed from the feeder mount carriage 7. The calculation of the collectively resupply period is performed for each of the plurality of component supply units 25.

Here, the plurality of component supply units 25 correspond to the plurality of component supply units 25 included in the object of component replenishment management support. For example, in the case of one component mounting machine 1, the plurality of component supply units 25 correspond to all the component supply units 25 included in the component mounting machine 1, and in the case of a production line in which a plurality of component mounting machines 1 are arranged in series, the plurality of component supply units 25 correspond to all the component supply units 25 included in the production line.

In step S117, a component to be supplied to the tape feeder 4 by the collective supply performed during the period in which the collective supply is possible is determined. Specifically, the tape feeder 4 to be replenished is specified from among the plurality of tape feeders 4 of the automatic loading type provided in the component supply unit 25. For example, when the number of components remaining in the component supply tape TP attached to the tape feeder 4 is equal to or greater than the number of components to be supplied by the tape feeder 4 based on the production plan when the presettable period is reached, it is not necessary to supply components to the tape feeder 4. Therefore, the tape feeder 4 is excluded from the object of component replenishment. The replenishment components for the plurality of replenishment target tape feeders 4 thus determined are determined.

In step S118, the determination result in step S117 is displayed on the display of the user interface 914 as the replenishment list T. Fig. 35 is a diagram showing an example of replenishment list T. In the replenishment list T, the possible replenishment period is indicated by the start time and the end time (for example, ts1 to te 1). The replenishment list T also shows a component supply unit 25 that can collectively replenish a period of time, and a component (P1a, P1b … …, and the like) that is to be replenished to each

feeder

4a, 4b, 4c, 4d, … … of the component supply unit 25 by collectively replenishing the component in the collectively replenishable period of time. Further, the components P1a, P1b, and … … are displayed for each replenishment target tape feeder 4 among the plurality of tape feeders 4 included in the component supply unit 25 as the target, and "-" indicating that there is no component to be replenished is displayed for the tape feeders 4 other than the replenishment target tape feeder 4.

In the component mounting system 9 including the component replenishment support device 91, an operator can perform a batch replenishment preparation for preparing the component supply reel 6 (component supply tape TP) corresponding to a component to be replenished by subsequent batch replenishment on the component replenishment carriage 8 at a work site separated from the component supply section 25 of the component mounting machine 1 while referring to the replenishment list T of fig. 35.

Fig. 36 is a flowchart showing an example of the collective replenishment preparation. The flowchart is executed by the calculation of the calculation unit 911 of the component replenishment support apparatus 91. In step S201, the presence or absence of a designation for replenishment is confirmed. Specifically, the operator can specify one of the plurality of collectively resupply periods indicated in the resupply list T displayed on the user interface 914, and the calculation unit 911 determines that the preparation for the collectively resupply corresponding to the specified collectively resupply period has been started.

In step S202, it is checked whether or not the replenishment carriage ID86 is acquired. Specifically, when the worker reads the replenishment carriage ID86 of the component replenishment carriage 8 that performs the preparation for batch replenishment using the reader 915, the calculation unit 911 determines that the replenishment carriage ID86 read by the reader 915 has been acquired (yes in step S202). Thus, the calculation unit 911 can specify the component replenishment carriage 8 to be subjected to the batch replenishment preparation using the replenishment carriage ID 86.

Next, the operator takes out the component supply reel 6 to be placed on the reel mounting table 85 of the component supply cart 8 in preparation for batch replenishment from the component library while referring to the replenishment list T, and reads the component ID64 and the reel ID63 attached to the component supply reel 6 by the reader 915. The component ID64 and the reel ID63 thus read by the reader 915 are acquired by the arithmetic unit 911 (yes in steps S203 and S204).

The operator mounts the tape placement unit 5 in the unit insertion slot 831 of the component supply cart 8 while holding the tip end portion of the component supply tape TP drawn out from the component supply reel 6 in the tape placement unit 5. At this time, the operator refers to the replenishment list T and attaches the tape placement unit 5 to the unit insertion slot 831 corresponding to the placement position S of the tape feeder 4 to which the component in the component supply tape TP is to be replenished. Upon receiving the signal, the communication unit 803 of the component replenishment carriage 8 transmits the placement position S corresponding to the unit slot 831 in which the tape placement unit 5 is mounted to the communication unit 913 of the component replenishment support device 91, and the calculation unit 911 acquires the placement position S received by the communication unit 913 (yes in step S205).

When all the information of the component ID64, the reel ID63, and the placement position S is acquired (yes in step S206), it is determined whether or not the combination thereof matches the substrate data based on the production plan (step S207). Specifically, since the component ID64 to be placed on the tape feeder 4 is set for each placement position S of the tape feeder 4 in the substrate data, it is checked whether or not the component ID64 of the placement position S indicated by the substrate data matches the component ID64 corresponding to the reel ID63 attached to the placement position S of the feeder mount carriage 7. For example, if the worker mistakenly attaches the unit slot 831 of the tape placing unit 5, the combination of these items does not match the substrate data, and the determination in step S207 is no. As a result, a warning indicating that the combination does not match the substrate data is displayed on the user interface 914 (step S208), and the process proceeds to step S210. On the other hand, when the combination of the components matches the board data (yes in step S207), the arithmetic unit 911 generates the element correspondence information Ip in which the components are associated with each other, stores the element correspondence information Ip in the storage unit 912 (step S209), and proceeds to step S210.

Incidentally, when the combination of the component ID64, the reel ID63, and the placement position S matches the substrate data based on the production plan, the calculation unit 911 may further perform replenishment list matching determination of determining whether or not the replenishment list T generated based on the past production progress acquired in step S102 matches the current production progress. That is, in a case where production is interrupted due to an error or the like in the middle, there is a possibility that a situation may occur in which, during the collectively replenishable period calculated from the progress status (step S102) acquired for creation of the replenishment list T, presetting cannot be performed on some of the tape feeders 4 that are the objects of collectively replenishing, and collectively replenishing cannot be performed. Therefore, during the collectively replenishable period, the collective replenishment can be performed in accordance with the replenishment list T, that is, when the replenishment list T matches the current production progress, the determination in step S207 may be yes, whereas when they do not match, the determination in step S207 may be no.

In step S210, it is determined whether the batch replenishment preparation is completed. Specifically, it is determined whether or not the tape placing units 5 are mounted in all the unit slots 831 corresponding to the placement positions S of all the replenishment target tape feeders 4 designated as targets for the collective replenishment in step S201. In the case where there is a unit slot 831 in which the tape placing unit 5 is not mounted, it is determined that the one-time replenishment preparation is not completed (no in step S210), and the process returns to step S203. On the other hand, when the mounting of the tape placing units 5 to all the unit slots 831 is confirmed, it is determined that the one-time replenishment preparation is completed (yes in step S210).

When the preparation for collective replenishment is completed in this way, the element correspondence information Ip shown in fig. 37 is stored in the storage unit 912. Here, fig. 37 is a diagram schematically showing an example of element correspondence information. In fig. 37, the diagonally hatched set positions S2, S4, and S5 correspond to the set position S of the supply target tape feeder 4. In this way, the component correspondence information Ip in which the placement position S is associated with the component ID64 and the reel ID63 of the component supply tape TP on the tape placement unit 5 corresponding to the placement position S is generated and stored for the placement position S of each supply-target tape feeder 4.

The component replenishment carriage 8 having completed the preparation for the collective replenishment is mounted on the feeder mounting carriage 7 of the target component supply unit 25. In the preparation operation for the feeder mounting carriage 7, which is executed prior to the preparation for the batch replenishment, the feeder correspondence information If shown in fig. 38 is generated for the feeder mounting carriage 7 and stored in the storage unit 912 in advance. Here, fig. 38 is a diagram schematically showing the contents of feeder correspondence information. As shown in fig. 38, the feeder correspondence information If indicates the placement position S of the feeder mount carriage 7 in association with the feeder ID421 of the tape feeder 4 mounted to the placement position S, and the feeder correspondence information If is generated and stored for each of the plurality of placement positions S of the feeder mount carriage 7.

When the component replenishment carriage 8 is mounted on the feeder mounting carriage 7 of the component supply unit 25, the plurality of tape placement units 5 mounted on the component replenishment carriage 8 are engaged with the plurality of replenishment-target tape feeders 4, respectively, in the manner shown in fig. 24 to 32C. As a result, the component supply tapes TP held by the tape placing units 5 are mounted on the supply-target tape feeders 4.

In addition, as the component replenishment carriage 8 is mounted on the feeder mounting carriage 7, the component correspondence information Ip relating to the component replenishment carriage 8 and the feeder correspondence information If relating to the feeder mounting carriage 7 are integrated (data is merged), and component feeder information Ipf is generated (fig. 39). Fig. 39 is a diagram schematically showing the contents of the component feeder information. As shown in fig. 39, the component feeder information Ipf indicates, for each of the plurality of supply-target tape feeders 4, a feeder ID421, a component ID64, and a reel ID63 corresponding to the same placement position S in association with each other.

The replenishment list matching determination may be performed before the component replenishment carriage 8 is mounted on the feeder mounting carriage 7 of the component supply unit 25. That is, the replenishment list matching determination may be executed for the replenishment list T referred to in preparation for the component replenishment carriage 8 to be mounted later, and the mounting of the component replenishment carriage 8 may be permitted in the case of the matching, while the mounting of the component replenishment carriage 8 may be prohibited in the case of the non-matching, and a warning may be issued to the operator.

In the above-described embodiment, in the component mounting machine 1, the plurality of tape feeders 4 each having the mounting location 441 are disposed in the component supply unit 25, and the plurality of tape feeders 4 supply components accommodated in the component supply tape TP mounted to the respective mounting locations 441. Moreover, component replenishment can be efficiently performed in the component mounting apparatus 1. Specifically, the component replenishment carriage 8 is used when components are replenished to the tape feeder 4 of the component mounter 1. The component replenishment carriage 8 has a plurality of unit insertion grooves 831 corresponding to the plurality of tape feeders 4, respectively. By mounting the component supply cart 8 on the component supply section 25 of the component mounting apparatus 1, the component supply tapes TP held in the unit slots 831 corresponding to the respective plurality of supply-target tape feeders 4 out of the plurality of tape feeders 4 (in other words, located at the same placement position S) can be collectively mounted on the mounting locations 441 of the respective plurality of supply-target tape feeders 4 (collectively supplied). In particular, a replenishment list T (preparation plan) indicating the component supply tapes TP to be held in the unit slots 831 of the component replenishment carriage 8 for preparation for batch replenishment is calculated based on the production plan. Therefore, in parallel with component mounting by the component mounting machine 1, the component supply tape TP is prepared on the component replenishment carriage 8 based on the production plan, and the component supply tape TP can be replenished to the plurality of replenishment-target tape feeders 4 by performing collective replenishment at the timing when replenishment is necessary. In this way, in the present embodiment, component replenishment to the tape feeder 4 can be efficiently performed.

Further, a user interface 914 for displaying the replenishment list T to the worker is provided. In this configuration, the operator can prepare the component supply tape TP on the component supply cart 8 while checking the supply list T displayed on the user interface 914.

Further, the component supply tape TP is provided with component information (reel ID63 and component ID64) relating to the components accommodated in the component supply tape TP. On the other hand, if the element correspondence information Ip indicating the correspondence between the element information of the element supply tape TP held in the unit socket 831 and the unit socket 831 does not match the production plan (no in step S207), the arithmetic unit 911 issues a warning to the operator (step S208). In this configuration, when an error occurs in the preparation operation for preparing the component supply tape TP for the component replenishment carriage 8, a warning can be given to the operator.

Further, the tape feeder 4 is provided with feeder information (feeder ID421) concerning the tape feeder 4. In contrast, the calculation unit 911 acquires the component correspondence information Ip indicating the correspondence between the unit slot 831 and the component information of the component supply tape TP held in the unit slot 831, and the feeder correspondence information If indicating the correspondence between the unit slot 831 and the feeder information of the tape feeder 4 corresponding to the unit slot 831. When the component supply cart 8 is mounted on the feeder mount cart 7 of the component supply unit 25, component feeder information Ipf is generated in which the component information of the component supply tape TP held in the unit slot 831 and the feeder information of the tape feeder 4 are indicated in association with each other with respect to the unit slot 831 and the tape feeder 4 that correspond to each other (that is, correspond to the same placement position S). In this configuration, component feeder information Ipf is generated in association with the attachment of the component supply cart 8 to the component supply unit 25. Therefore, the arrangement of the component supply tape TP with respect to the tape feeder 4 after component feeding can be accurately grasped from the component feeder information Ipf.

Both the preceding tape placing unit 5A and the subsequent tape placing unit 5B can be engaged with and disengaged from the tape feeder 4. Then, one tape placing unit 5 of the preceding tape placing unit 5A and the subsequent tape placing unit 5B is engaged with the tape feeder 4, and the component supply tape TP held by the one tape placing unit 5 is attached to the attachment portion 441 of the tape feeder 4. Further, the subsequent tape placing unit 5B can be attached to the unit slot 831 of the component replenishment carriage 8, and the component supply tape TP held in the subsequent tape placing unit 5B is held in the unit slot 831 by attaching the subsequent tape placing unit 5B to the unit slot 831. When the component supply cart 8 having the subsequent tape placing unit 5B attached to the unit insertion slot 831 corresponding to the supply-target tape feeder 4 is attached to the component supply unit 25 in a state where the preceding tape placing unit 5A is engaged with the supply-target tape feeder 4, the subsequent tape placing unit 5B engages with the supply-target tape feeder 4 while pushing out the preceding tape placing unit 5A and detaching the preceding tape placing unit 5A from the supply-target tape feeder 4. In this configuration, by the operation of attaching the component supply cart 8 to the component supply unit 25, the tape placing unit 5 attached to the supply-target tape feeder 4 can be replaced from the preceding tape placing unit 5A to the succeeding tape placing unit 5B, and thus the component supply tape TP held by the succeeding tape placing unit 5B can be easily attached to the supply-target tape feeder 4.

The present invention is not limited to the above-described embodiments, and various modifications can be made to the above-described embodiments without departing from the spirit of the invention. Fig. 40 is a flowchart showing a modification of the collective compensation. The flowchart is executed by the calculation of the calculation unit 911 of the component replenishment support apparatus 91.

In step S301, it is checked whether or not the reader 78 of the feeder mount carriage 7 has acquired the supply carriage ID86 of the component supply carriage 8 with the component supply carriage 8 mounted on the feeder mount carriage 7 of the component supply unit 25. When the supply cart ID86 is acquired (yes in step S301), it is determined whether or not the supply cart ID86 is appropriate, that is, whether or not the supply cart ID86 of the component supply cart 8 to be attached to the component supply unit 25 for the collective supply is determined (step S302).

When the replenishment carriage ID86 is not appropriate (no in step S302), the user interface 914 displays a warning indicating that the combination of the component replenishment carriage 8 and the component supply unit 25 is not appropriate (step S303).

When the replenishment carriage ID86 is appropriate (yes in step S302), the tape sensor 491 determines whether or not the component supply tape TP held by the component replenishment carriage 8 is mounted on the mounting location 441 of the tape feeder 4 to which the tape sensor 491 belongs. That is, when the unit replacement is performed, since the component supply tape TP that is one of the components falls from the mounting portion 441 and the component supply tape TP that is the next component supply tape TP enters the mounting portion 441, the presence state of the component supply tape TP changes at the mounting portion 441 in the order of the presence of the component supply tape TP, the absence of the component supply tape TP, and the presence of the component supply tape TP. Therefore, the tape sensor 491 can confirm the mounting of the component feeding tape TP held on the component replenishment carriage 8 to the mounting portion 441 based on the change.

This mounting confirmation is performed individually for each of the plurality of tape feeders 4 held by the feeder mount carriage 7. Then, it is checked whether or not the detection position of the tape feeder 4 is proper, that is, whether or not the placement position S of the tape feeder 4 matches the placement position S of the replenishment-target tape feeder 4, with respect to the tape feeder 4 for which the mounting of the component supply tape TP is detected (step S305). The tape feeder 4 determined in step S305 to have an appropriate (yes) detection portion is integrated with data as shown in fig. 39 to generate component feeder information Ipf (step S306). On the other hand, the user interface 914 does not perform data matching for the tape feeder 4 determined in step S305 to have an inappropriate detection position, and displays a warning that the tape feeder 4 as the mounting destination of the component supply tape TP held on the component replenishment carriage 8 is inappropriate (step S303).

In step S307, it is checked whether or not mounting of the component supply tape TP held on the component supply carriage 8 is detected for all of the supply-target tape feeders 4 that are supplied in a batch. When the mounting of the component supply tape TP is not detected for all the supply-target tape feeders 4 (no in step S307), the user interface 914 indicates that there is a supply-target tape feeder 4 for which the component supply tape TP is not supplied.

In this modification, the plurality of tape feeders 4 include tape sensors 491 for detecting attachment of the component supply tapes TP to the respective attachment locations 441. On the other hand, when the component supply cart 8 is mounted to the component supply unit 25, the calculation unit 911 generates component feeder information Ipf for the supply-target tape feeder 4 whose mounting of the component supply tape TP to the mounting location 441 is detected, and does not generate component feeder information Ipf for the supply-target tape feeder 4 whose mounting of the component supply tape TP to the mounting location 441 is not detected (steps S304 to S306). In this configuration, for example, when the mounting of the component supply tape TP to the supply-target tape feeder 4 fails due to a failure such as the tape placing unit 5 falling off the component supply carriage 8 during the conveyance of the component supply carriage 8, appropriate component feeder information Ipf reflecting the failure can be generated.

When it is confirmed that there is a replenishment tape feeder 4 for which the arrangement of the component supply tape TP to the mounting portion 441 has not been detected after the component replenishment carriage 8 is mounted to the component supply unit 25 (no in step S307), the calculation unit 911 issues a warning to the operator (step S303). In this configuration, for example, when the component supply tape TP fails to be mounted on the supply-target tape feeder 4 due to a failure in the middle of conveyance of the component supply carriage 8, a warning can be issued to the operator.

When the mounting of the component supply tape TP to the mounting location 441 of the tape feeder 4 other than the supply-target tape feeder 4 among the plurality of tape feeders 4 is detected in association with the mounting of the component supply carriage 8 to the component supply unit 25 (step S305), the calculation unit 911 issues a warning to the operator (step S303). In this configuration, when the component supply tape TP is erroneously mounted on a tape feeder 4 different from the replenishment-target tape feeder 4, a warning can be issued to the operator.

The component feeding carriage 8 is attached with a feeding carriage ID86 for identifying the component feeding carriage 8, and the feeder mounting carriage 7 of the component supply unit 25 includes a reader 78 for reading the feeding carriage ID86 attached to the component feeding carriage 8 attached to the feeder mounting carriage 7. On the other hand, when the combination of the component supply cart 8 and the component supply unit 25 indicated by the supply cart ID86 read by the reader 78 is not appropriate (no in step S302), the calculation unit 911 issues a warning to the operator (step S303). In this configuration, it is possible to suppress the component replenishment carriage 8 from being mounted on the wrong component supply unit 25.

Further, a modification different from the modification shown here can be added to the above embodiment. For example, the feeder to be collectively replenished is not limited to a tape feeder, and may be a tray feeder as shown in fig. 41. Fig. 41 is a diagram schematically showing the structure of a tray feeder as a target of the batch replenishment.

As shown in fig. 41, the component mounter 120 mounts components mounted on a tray 121 on a substrate B, and includes a plurality of shelves 123 (component supply units) stacked in the Z direction. The plurality of racks 123 correspond to "feeders", and each rack 123 has a bottom surface 123a on which the tray 121 is mounted. Each rack 123 delivers the tray 121 to a tray pull-out member (not shown) from the bottom surface 123a, and the mounting head mounts the components on the tray 121 supplied from the rack 123 via the tray pull-out member onto the substrate B. The component mounting apparatus 120 further includes a tray collection unit 125 for collecting empty trays 121 below the plurality of shelves 123.

On the other hand, the component replenishment carriage 8 has a plurality of tray insertion slots 87 corresponding to the plurality of shelves 123. In step S401, the component replenishment carriage 8 that holds the tray 121 in each tray slot 87 corresponding to each replenishment target rack 123 (empty rack 123) among the plurality of racks 123 is conveyed toward the component mounting apparatus 120. Then, the component replenishment carriage 8 reaches the component mounting machine 120 (step S402), and the tray pushing members 871 provided in the tray insertion grooves 87 are moved to the component mounting machine 120 side (step S403), whereby the component replenishment carriage 8 is mounted on the component supply unit (i.e., the plurality of shelves 123) of the component mounting machine 1. In this way, the tray slots 87 are attached to the plurality of supply racks 123, respectively, and the supply is completed all at once. The above embodiment can be similarly applied to such a configuration.

Further, a modification in which the arithmetic unit 911 repeatedly executes the element replenishment support shown in fig. 34 is also conceivable. In this modification, for example, each time the execution time set at a predetermined interval is reached, the acquisition of the production plan, the acquisition of the production progress, and the acquisition of the substrate data are executed (steps S101, S102, and S103), and the replenishment list T is generated based on the real-time production progress at the execution time.

Further, it is not necessary to represent the timing of performing the collective replenishment as a collective replenishment possible period having a temporal width. That is, as the timing of performing the batch replenishment, the time at which the batch replenishment is possible (for example, the start time of the batch replenishment possible period) can be displayed to the operator. In this case, the replenishment list T may be deformed as shown in fig. 42.

Fig. 42 is a diagram schematically showing a modification of the replenishment list. In the replenishment list T of fig. 42, it is indicated whether or not the tape feeders 4 placed at the placement positions S1, S2, and … … can be preset at the time of batch replenishment availability, whether or not replenishment is required, and whether or not replenishment is performed (unused/performed/disabled). Here, the phrase "replenishment is not required" (the column of "replenishment execution" is "unnecessary") means that although the presetting can be executed on the target tape feeder 4, the component replenishment on the tape feeder 4 is not required because the production plan can be completed using the remaining components in the component supply tape TP attached to the tape feeder 4, and thus the component replenishment on the tape feeder 4 is not required. The execution of replenishment ("execution of replenishment" is indicated by "execution" in the column) means that the tape feeder 4 to be subjected to the presetting can be executed, and since the production plan cannot be completed by the components remaining in the component supply tape TP attached to the tape feeder 4, the components need to be replenished to the tape feeder 4 in order to continue the production plan, and thus the component replenishment to the tape feeder 4 is executed. The "failure to replenish" (the column of "execution of replenishment" is "failure") means that the production plan cannot be completed by the components remaining in the component supply tape TP attached to the target tape feeder 4, and components need to be replenished to the tape feeder 4 to continue the production plan, but the component replenishment to the tape feeder 4 cannot be executed because the presetting to the tape feeder 4 cannot be executed.

According to the example of the replenishment list T, at the time of the collective replenishment, the tape feeder 4 at the placement position S1 cannot be preset, and thus the replenishment of components is not necessary. As a result, the tape feeder 4 at the set position S1 does not need to be replenished at the time of collective replenishment. The tape feeder 4 at the set position S2 can be preset at the collective replenishment timing, and components need to be replenished. As a result, the tape feeder 4 at the set position S2 is replenished at the time when the batch replenishment is possible. In addition, the tape feeder 4 at the set position S3 requires component replenishment at the time of batch replenishment, but cannot be preset. As a result, the tape feeder 4 at the set position S3 was not replenished.

Alternatively, the feeder engaging portion is constituted by an engaging hole (feeder engaging hole 412), and the unit engaging portion is constituted by an engaging projection (unit engaging projection 572). However, the feeder engaging portion may be constituted by an engaging protrusion, and the unit engaging portion may be constituted by an engaging hole. The other engaging holes and engaging projections may be configured by appropriately exchanging them.

The component replenishment carriage 8 may be conveyed by an unmanned conveyance vehicle without being carried by an operator. Alternatively, a robot may be appropriately used for preparation for batch replenishment with respect to the component replenishment carriage 8.
