Description

The present invention relates to a parts supply carriage provided with a feeder holding portion for holding a tape feeder and a reel holding portion capable of holding a reel wound with tape for storing parts, and a parts mounting device equipped with the same. is there.

Conventionally, a component mounting device has been used to mount an electronic component (hereinafter referred to as "component") such as a chip component or an IC on a printed circuit board. The component mounting device is replaceably equipped with a component supply carriage for supplying components. The parts supply carriage includes a reel holding unit that holds a reel on which a tape for accommodating parts is wound, and a tape feeder that sends out tape from the reel to supply parts. As the types of parts supplied increase, so does the total number of reels that must be held by the parts supply carriage. Further, in order to omit the splicing work, when an autoloading feeder (ALF) having an autoloading function is used as the tape feeder, it is necessary to arrange a plurality of reels in the reel holding portion for the autoloading feeder. Yes, this is one of the main factors that increase the total number of reels. Therefore, for example, in the apparatus described in Patent Document 1, the total number of reels that can be held in the parts supply carriage is increased by adding an additional reel holding portion in addition to the standard reel holding portion as the reel holding portion.

More specifically, in the apparatus described in Patent Document 1, two arm extension members are additionally provided on the rear side with respect to the standard reel holding portion. Then, the first rod-shaped mounting seat is connected between these arm extension members, and the second rod-shaped mounting seat is further separated rearward from the first rod-shaped mounting seat and between the arm extension members. The seats are connected. In this way, the fixing mechanism is formed by the two arm extension members and the two rod-shaped mounting seats. Then, when increasing the total number of reels, an additional reel holding portion is placed on the fixing mechanism.

In the apparatus described in Patent Document 1, it is possible to flexibly deal with the total number of reels used by attaching / detaching the additional reel holding portion. However, the fixing mechanism is connected to the standard reel holding portion, which is a factor that reduces workability. For example, when designing the fixing mechanism, it is necessary to consider the maximum value of the reel held by the additional reel holding portion, and the distance from the standard reel holding portion to the rear end of the fixing mechanism is relatively long. Further, when it is not necessary to increase the number of reels, the additional reel holding portion can be removed, but the fixing mechanism remains. Therefore, operators need to access the standard reel holder from a rear position beyond the fixing mechanism. Further, when replacing the parts supply trolley, it is necessary to move the parts supply trolley so that the fixing mechanism protrudes rearward from the standard reel holding portion. As described above, there is room for improvement in workability in the conventional parts supply carriage.

The present invention has been made in view of the above problems, and is a component supply carriage having excellent workability while flexibly responding to the total number and sizes of reels that can be held, and a component mounting provided with the component supply carriage.

Shown, FIG. 6 shows how the standard reel holder 630 and the additional reel holder 650 hold the 7-inch reel 7. The drawer mechanism 640 is arranged between the standard reel holding portion 630 and the waste tape collection box 670 in the vertical direction Z. The pull-out mechanism 640 has two rail members 641 and 642 extending in the Y direction.

The rail member 641 is arranged on the side plate 623 on the (+ X) direction side. In the side plate 623 on the (+ X) direction, a slider (not shown) slidably attached to the rail member 641 is fixed to the side end of the side plate 623 on the (+ X) direction on the (+ Y) direction. ing. Therefore, the rail member 641 is reciprocating in the Y direction with respect to the standard reel holding portion 630 fixed to the side plate 623 on the (+ X) direction side.

Further, the rail member 642 is arranged on the side plate on the (−X) direction side (not shown), and has the same configuration as the rail member 641. That is, a slider (not shown) slidably attached to the rail member 642 is fixed to the side end portion of the side plate on the (−X) direction side on the (+ Y) direction side. Therefore, the rail member 642 is reciprocating in the Y direction with respect to the standard reel holding portion 630.

As shown in FIGS. 4A and 4B, the pair of rail members 641 and 642 are separated from each other in the X direction by substantially the same width as the width in the X direction of the standard reel holding portion 630, but are separated from each other in the (+ Y) direction. The ends are connected by a support roller 643. Similar to the support rollers 631 and 632 provided on the standard reel holding portion 630, the support roller 643 has a plurality of unit rollers having a predetermined width having substantially the same length as the separation interval of the pair of side plates 623 in the X direction. It is configured by being continuously attached to a roller shaft (reference numeral 643a in FIG. 15).

A sheet metal member 644 is attached to the pair of rail members 641 and 642 in addition to the support roller 643. As shown in FIGS. 4B, 5 and 6, the sheet metal member 644 is provided adjacent to the support roller 643 on the (-Y) direction side, and the end portion thereof on the (-Y) direction side is bent upward. Has been done. Further, a positioning slit is provided at the bent tip portion, and the second reel 7B can be rotatably held by the positioning slit and the support roller 643. In this way, the support roller 643 and the sheet metal member 644 form an additional reel holding portion 650. The additional reel holding unit 650 can also hold the reel holder that rotatably holds the second reel 7B by using the support roller 643, the positioning slit, or the like (see FIGS. 11 and 14). ).

As described above, according to the present embodiment, the drawer mechanism 640 has an additional reel holding portion 650 composed of the support roller 643 and the sheet metal member 644, and holds the standard reel in response to a manual operation by the user. It is possible to enter and exit the unit 630 on the (+ Y) direction side. That is, as shown in FIG. 4A, while the pair of rail members 641 and 642 are located directly below the standard reel holding portion 630, the drawer mechanism 640 is stored at a position directly below the standard reel holding portion 630, which is substantially present. Has the same size as the conventional batch exchange trolley. On the other hand, as shown in FIG. 4B, when the pair of rail members 641 and 642 are integrally pulled out together with the support roller 643 and the sheet metal member 644 toward the (+ Y) direction of the standard reel holding portion 630, other than the standard reel holding portion 630. In addition, an additional reel holding unit 650 is additionally added, and the total number of reels that can be held by the carriage 6 can be increased. In this way, the placement location (reel holding portion) of the reel 7 can be increased according to the usage mode of the carriage 6, and the total number of reels 7 to be held can be flexibly dealt with.

Further, in the case where the second reel 7B is not loaded on the additional reel holding portion 650 due to reasons such as not presetting the second reel 7B, the drawer mechanism 640 is positioned directly below the standard reel holding portion 630 as shown in FIG. 4A. Can be stored in. Further, even when the second reel 7B is loaded on the additional reel holding portion 650, the withdrawal amount of the drawing mechanism 640 can be suppressed to an amount corresponding to the second reel 7B. Therefore, the workability of the carriage 6 is significantly improved as compared with the conventional technique in which a relatively large fixing mechanism is always connected to the rear side of the standard reel holding portion (corresponding to the upstream side of the delivery direction Y of the present embodiment). Can be done.

Further, in the present embodiment, the reel size that can be held by the additional reel holding unit 650 can be switched by adjusting the pulling amount of the pulling mechanism 640. For example, when the auto-loading function is used to supply parts using a reel 7 having a relatively large diameter, for example, a 13-inch reel 7, the carriage 6 shown in FIG. 5 can be used. That is, a 13-inch first reel 7A is loaded on the standard reel holding portion 630, and a 13-inch second reel is added to the additional reel holding portion 650 by pulling out the drawer mechanism 640 by the drawer amount D13 corresponding to the 13-inch reel. Load 7B. On the other hand, when parts are supplied by the auto-loading function using a reel 7 having a relatively small diameter, for example, a 7-inch reel 7, the withdrawal amount corresponds to the 7-inch reel 7, as shown in FIG. The amount is suppressed to D7, and the standard reel holding portion 630 and the additional reel holding portion 650 are loaded with the 7-inch first reel 7A and the second reel 7B, respectively. It should be noted that matching the reel size of the second reel 7B to the reel size of the first reel 7A is not an essential item in the parts supply process, and in the case where the second reel 7B of a different size is loaded on the additional reel holding portion 650, The pull-out mechanism 640 may be pulled out by a pull-out amount suitable for holding the second reel 7B. In this way, it is possible to flexibly respond to the reel size.

FIG. 7 is a partial perspective view of a second embodiment of the parts supply carriage according to the present invention. In the figure, in order to clarify the characteristic configuration of the second embodiment, the illustration of the standard reel holding portion is intentionally omitted. The major difference between the second embodiment and the first embodiment is that a movement restricting unit 645 is provided to fix the extraction position of the extraction mechanism 640 and restrict the reciprocating movement of the additional reel holding unit 650 in the delivery direction Y. That is the point. The movement restricting unit 645 is provided on the (+ X) direction side and the (-X) direction side of the withdrawal mechanism 640, both of which have the same configuration. Therefore, in the following, the configuration of the movement regulation unit 645 on the (−X) direction side will be described with reference to FIG. 7, and the movement regulation unit 645 on the (+ X) direction side will be described with the same reference numerals to the same configuration. Is omitted.

In the second embodiment, in order to fix the drawer mechanism 640 at an appropriate position for each reel size, a portion of the upper surface of the rail member 642 on the (-X) direction side corresponding to an appropriate withdrawal amount for each reel size A position fixing hole 642a is provided (see the partially enlarged view of FIG. 7). Then, the movement restricting unit 645 uses these position fixing holes 642a to fix the drawer mechanism 640. That is, the movement restricting unit 645 has a fixing member 646 fixed to the side plate 623 and a position fixing pin 647 for positioning and fixing the rail member 642 with respect to the fixing member 646.

As shown in the partially enlarged view of FIG. 7, the fixing member 646 is provided with two position fixing through holes 646a and 646b apart from each other in the Y direction. The tip of the position fixing pin 647 is removable with respect to these through holes 646a and 646b. In the present embodiment, when the drawer mechanism 640 is stored at a position directly below the standard reel holding portion 630 (hereinafter referred to as “retracted”), one of the position fixing holes 642a is located at a position directly above the through hole 646a. The positions where the through holes 646a and the position fixing holes 642a are provided are preset. Therefore, as shown in FIG. 7, the tip of the position fixing pin 647 is inserted into the position fixing hole 642a via the through hole 646a at the time of storage, so that the drawer mechanism 640 is fixed in the stored state.

Further, when the drawer mechanism 640 is pulled out by the amount of the drawer corresponding to the reel size (hereinafter referred to as “at the time of drawer”), the through hole is provided so that one of the position fixing holes 642a is located directly above one of the through holes 646b. The positions where the 646b and the position fixing hole 642a are provided are preset. Therefore, as shown in FIG. 8, the tip of the position fixing pin 647 is inserted into the position fixing hole 642a via the through hole 646b at the time of pulling out, so that the position corresponding to the reel size of the second reel 7B is reached. The drawn-out mechanism 640 is fixed by the additional reel holding portion 650 while holding the second reel 7B. As a result, the movement restricting unit 645 restricts the movement of the additional rail holding unit 650 in the Y direction. Reference numeral 648 in FIG. 8 is a chain in which the position fixing pin 647 is connected to the fixing member 646, and the chain 648 prevents the position fixing pin 647 from being lost.

As described above, in the second embodiment, since the movement restricting unit 645 is provided on the (+ X) direction side and the (-X) direction side of the drawer mechanism 640, it is certain that the drawer mechanism 640 moves when retracted. Can be prevented. Further, the additional reel holding portion 650 can be added to a position suitable for the reel size of the second reel 7B. Further, the position fixing pin 647 restricts the reciprocating movement of the additional reel holding portion 650 in the Y direction. Therefore, the second reel 7B can be held at an appropriate position, and the tape 40 can be stably fed from the second reel 7B.

In the second embodiment, the movement restricting unit 645 is provided on both the (+ X) direction side and the (-X) direction side of the withdrawal mechanism 640, but the movement restricting unit 645 may be provided on only one of them. Good. Further, in the second embodiment, the through hole 646a is made to function for storage, while the through hole 646b is made to function for drawing. However, such functional separation is optional, for example, the through hole 646a is for storage. Not only that, it may also function as a drawer for some reel sizes. Also, one through hole may function for storage and for drawing out all reel sizes. Further, the movement control unit 645 may be applied to the embodiment described below.

By the way, in the first embodiment and the second embodiment, the first reel 7A is directly loaded and held on the standard reel holding portion 630, but for example, the first reel 7A is held in the reel holder. It may be loaded on the standard reel holding unit 630 (third embodiment).

FIG. 9 is a side view showing a third embodiment of the parts supply carriage according to the present invention. In this third embodiment, the reel holder 71A that rotatably holds the first reel 7A is held by the standard reel holding portion 630. Further, in the third embodiment, the drawer mechanism 640 has a retracted state stored at a lower position of the standard reel holding portion 630 and a drawn state drawn to the upstream side of the delivery direction Y, that is, the (+ Y) direction side. It is possible to switch between. In particular, as shown in FIG. 9, when the drawer mechanism 640 is in the retracted state, the support roller 643 of the drawer mechanism 640 is engaged with the lower end portion of the reel holder 71A on the (+ Y) direction side. Therefore, the movement of the reel holder 71A in the (+ Y) direction is restricted by the support roller 643, and the reel holder 71A can be stably held by the standard reel holding portion 630. As a result, the tape 40 can be stably transmitted from the first reel 7A. As described above, in the present embodiment, the support roller 643 of the pull-out mechanism 640 functions as an example of the "holder movement restricting unit" of the present invention.

Further, also in the third embodiment, similarly to the first embodiment, the pull-out mechanism 640 is pulled out in the (+ Y) direction by the withdrawal amount D7b corresponding to the reel size of the second reel 7B, so that the reel holder 71A (+ Y) An additional reel holding portion 650 for the second reel 7B can be added on the directional side (FIG. 10). Therefore, the second reel 7B can be directly loaded on the additional reel holding portion 650, and the same effect as that of the first embodiment can be obtained.

Further, in FIG. 10, the second reel 7B is directly held by the additional reel holding portion 650, but as shown in FIG. 11, the drawer mechanism 640 is pulled out in the (+ Y) direction by the withdrawal amount D71b corresponding to the reel holder 71B. The additional reel holding portion 650 for the reel holder 71B may be added. In this case, the second reel 7B can be loaded on the additional reel holding portion 650 via the reel holder 71B, and the same effect as that of the first embodiment can be obtained.

Further, the movement control unit 645 may be added to the third embodiment configured as described above, as in the second embodiment, and the addition may produce the same effects as those in the second embodiment. Be done.

FIG. 12 is a perspective view showing a configuration of a reel holder used in the fourth embodiment of the parts supply carriage according to the present invention. In the column (a) of the figure, a perspective view showing a state in which the reel 7 is held is shown, and in the column (b), a disassembled assembly perspective view of the reel holder is shown. In the fourth embodiment, the reel holder 71A for the first reel 7A (hereinafter referred to as "holder 71A for the first reel") and the reel holder 71B for the second reel 7B (hereinafter referred to as "second reel holder 71A") arranged in the delivery direction Y. The reel holder 71B ”) has the same configuration. When the two are not distinguished, they are simply referred to as "reel holder 71".

The reel holder 71 has a pair of side plates 711 and 712 and a pair of side plates 711 and 712 arranged so as to face each other in the width direction X orthogonal to the delivery direction Y in which the tape 40 is sent out from the reel 7 from the width Wa of the reel 7. Also includes three connecting portions 713 to 715 that are connected to each other in a state of being separated by a wide interval Wb, and the pair of side plates 711 and 712 are detachable from each other by the connecting portions 713 to 715. That is, in the surface region of the side plate 711 on the (+ Y) direction side of the surface 711a facing the side plate 712, a removable pin 713a is erected on the (+ Y) direction side toward the side plate 712. On the other hand, in the surface region of the side plate 712 on the (+ Y) direction side of the surface 712a facing the side plate 711, an engaged member 713b configured to be engaged with the detachable pin 713a faces the side plate 711. It is provided. Then, when the side plates 711 and 712 are brought close to each other, the removable pin 713a is engaged with the engaged member 713b to form the connecting portion 713 as shown in the column (a) of FIG. The connecting portion 713 also functions as a supporting portion for supporting the reel 7.

Further, connecting portions 714 and 715 having the same configuration as the connecting portion 713 are also provided on the (-Y) direction side of the reel holder 71. That is, the removable pins 714a and 715a are erected on the surface region of the side plate 711 on the (-Y) direction side of the surface 711a, and are engaged with the surface region of the side plate 712 on the (-Y) direction side. Members 714b and 715b are provided, and when the side plates 711 and 712 are brought close to each other, the removable pins 714a and 715a engage with the engaged members 714b and 715b, respectively, as shown in column (a) of FIG. They are combined to form connecting portions 714 and 715. By forming the connecting portions 713 to 715, the pair of side plates 711 and 712 are integrated while forming a reel holding space having a space width Wb slightly wider than the X direction width Wa of the reel 7 in close proximity to each other, and the reel holder 71. Is formed.

Further, as shown in FIG. 12, a protrusion 716a is provided on the surface 711a of the side plate 711 at a position near the connecting portions 714 and 715, and a protrusion 716b is provided on the surface 712a of the side plate 712 facing the protrusion 716a. ing. Therefore, when the reel holder 71 is formed as described above, the tip portions of the protrusions 716a and 716b are close to each other to form a support portion 716 that supports the reel 7. That is, the reel holder 71 rotatably holds the reel 7 by the connecting portion 713 and the supporting portion 716. Therefore, the width size Wb of the reel holder 71 can be adjusted by replacing the removable pins 713a to 715a according to the width Wa of the reel 7 and appropriately changing the lengths of the removable pins 713a to 715a in the X direction. There is.

Steps are formed at the ends 711b and 712b of the pair of side plates 711 and 712 on the (-Y) direction side, and the ends 711b and 712b are provided close to the side plates 712 and 711, respectively, and the ends 711b and 712b The width Wc in the X direction is narrower than the space width Wb of the reel holding space. Therefore, when the reel holders 71A and 71B adjacent to each other are arranged adjacent to each other in the delivery direction Y, as shown in FIG. 13, the end portions 711b and 712b of the reel holder 71B form a pair of side plates 711 constituting the reel holder 71A. , 712 can enter the reel holding space formed between the ends 711c and 712c on the (+ Y) direction side, and the reel holders 71A and 71B can be arranged adjacent to the delivery direction Y. Reference numerals 717 in FIGS. 12 and 13 are width fixing bosses provided at the ends 711b and 712b, and when the reel holders 71A and 71B are adjacent to each other, the width fixing boss 717 of the reel holder 71B is a reel holder. Press the side plates 711 and 712 of 71A. As a result, as shown in FIG. 13, the reel holders 71A and 71B can be linearly arranged in the delivery direction Y, and the first reel 7A, the second reel 7B and the feeder 5 can be arranged as an example along the delivery direction Y. Can be arranged. Further, the reel holder 71B can restrict the movement of the reel holder 71A in the (+ Y) direction by the reel holders 71A and 71B adjacent to each other.

Further, two notches 711d and 711e are provided at the lower end of the side plate 711, and two notches 712d and 712e are provided at the lower end of the side plate 712. The cutouts 711d and 712d have a hook shape, and the reel holder 71A can be moved in the Y direction to engage with the support rollers 631 and 643. Therefore, as shown in FIG. 11, when the reel holder 71A is set in the standard reel holding portion 630, the support roller 631 engages with the notches 711d and 712d to restrict the upward movement of the reel holder 71A. it can. Further, when the reel holder 71B is set in the additional reel holding portion 650 in the same manner as the reel holder 71A, the support roller 643 engages with the hook-shaped notches 711d and 712d to restrict the upward movement of the reel holder 71B. be able to.

Further, the cutout portions 711e and 712e are cut out in a chevron shape so that they can be engaged with the support roller 632 and the sheet metal member 644. Therefore, as shown in FIGS. 9 to 11, when the reel holder 71A is set in the standard reel holding portion 630, the support roller 632 engages with the notches 711e and 712e and moves in the Y direction of the reel holder 71A. Movement can be regulated. Further, when the reel holder 71B is set in the additional reel holding portion 650, as shown in FIG. 11, a part of the sheet metal member 644 engages with the notches 711e and 712e, so that the reel holder 71B moves in the Y direction. Movement can be regulated.

Further, as shown in FIG. 11, a regulation member 636 is attached to the frame column 622. A slit (not shown) that can be engaged with the upper ends of the ends 711b and 712b is provided at the lower end of the regulating member 636. Therefore, the upward movement of the reel holder 71A can be restricted by engaging the ends 711b and 712b with the slits.

As described above, in the fourth embodiment, the reel holders 71A and 71B, the reel holder 71A and a part of the standard reel holding part 630, and the reel holder 71B and a part of the additional reel holding part 650 are engaged with each other. The movement of the reel holders 71A and 71B is restricted. As a result, it is possible to stably deliver the tape 40 from the reel 7 while preventing the reel 7 from moving.

Further, as shown in FIG. 11, in a state where the first reel holder 71A and the second reel holder 71B are set in the standard reel holding portion 630 and the additional rail holding portion 650, respectively, the first reel holder 71A and the first reel holder 71A and the first reel holder 71B are set. It is possible to prepare for the next component mounting using the 2-reel holder 71B. That is, by preparing another holder 71A for the first reel and the holder 71B for the second reel and inserting the ends 711b and 712b of the reel holder 71B into the reel holding space of the reel holder 71A, the widths of the reel holders 71A and 71B are wide. You can make adjustments.

Immediately after the first reel holder 71A and the second reel holder 71B are loaded on the standard reel holding portion 630 and the additional rail holding portion 650, the reel holders 71A and 71B, the reel holder 71A and the standard reel holding portion, respectively. The 630, as well as the reel holder 71B and the additional reel holder 650, are not or loosely engaged. However, by pushing the pull-out mechanism 640 in the retracting direction, that is, in the (-Y) direction after loading, the engagement proceeds, and the holder 71A for the first reel and the holder 71B for the second reel can be fixed more reliably. it can. As a result, it is possible to prevent the first reel 7A and the second reel 7B from coming off the carriage 6 from the carriage 6. On the contrary, by pulling the pull-out mechanism 640 in the pull-out direction, that is, in the (+ Y) direction, the engagement can be loosened or disengaged. As a result, the first reel holder 71A and the second reel holder 71B can be easily removed from the standard reel holding portion 630 and the additional rail holding portion 650, respectively.

Further, the holder 71A for the first reel and the holder 71B for the second reel have the same configuration and are shared to facilitate holder management. In addition, the reel can be switched for each holder 71, and workability can be further improved.

FIG. 14 is a partial perspective view showing a fifth embodiment of the parts supply carriage according to the present invention. Further, FIG. 15 is a partially enlarged perspective view of FIG. The major difference between the fifth embodiment and the first embodiment is that the second reel 7B is held by the additional reel holding unit 650 while being held by the second reel holder 71B, and the information notification unit. An example of this is that the dial type display 649 is attached to the drawer mechanism 640, and the other configurations are basically the same as those of the first embodiment. Therefore, in the following, the differences will be mainly described, and the same components will be designated by the same reference numerals and the description thereof will be omitted.

In the fifth embodiment, the drawer mechanism 640 is pulled out by the amount corresponding to the second reel holder 71B that rotatably holds the second reel 7B, and the additional reel holding portion 650 is added. Then, the second reel holder 71B is loaded on the additional reel holding portion 650. Therefore, the same action and effect as those of the first embodiment can be obtained.

Further, in the present embodiment, the second reel holder 71B is along one of the plurality of first reels 7A (reference numeral 7A1 in FIG. 14) held by the standard reel holding portion 630 and the delivery direction Y. They are arranged in a row. Then, the tape 40 is sent from the first reel 7A1 and the second reel 7B held in the second reel holder 71B to the feeder 5 having an auto-loading function, and parts are supplied. This makes it possible to switch from the conventional continuous supply of parts by splicing to the continuous supply of parts in reel units. On the other hand, the following problems may occur.

Conventionally, since the feeder 5 and the reel 7 were always connected by splicing or the like, the types of parts 46 that can be supplied by the feeder 5 were clear even when the feeder 5 was pulled out from the carriage 6. .. However, when the auto-loading function is used, if the feeder 5 is pulled out from the carriage 6 at the end of the reel, the edges of the feeder 5 and the reel 7 are cut off. As a result, the type of the part 46 attached to the feeder 5 may be unknown.

Therefore, in the present embodiment, as shown in FIG. 15, the drawer mechanism 640 is provided with a dial type display 649. In the present embodiment, the dial-type display 649 can display the mounting position number of the feeder 5 in production and the loading position number of the reel 7 on the drawer mechanism 640. By combining these, the feeder 5 can be displayed. The position of the reel 7 attached to is clarified. As a result, even if the edge between the feeder 5 and the reel 7 is broken, the mounting position of the feeder 5 can be specified from the history from the serial information and the loading information of the feeder 5. As a result, it is possible to reliably find the reel 7 used from the above-mentioned mounting position and holding position.

Further, since the feeder 5 having an auto-loading function supplies the parts 46 in reel units, preset work is always required. Here, in the feeder 5 having no autoloading function, it was possible to find the reel 7 to be spliced by following the tape 40 attached to the feeder 5, but this is not possible in the feeder 5 having the autoloading function. .. However, by disposing the dial type display 649 in the drawer mechanism 640, the holding position of the reel 7 becomes clear, and the preset work of the next reel 7 can be smoothly performed. In addition, it is possible to prevent the reel 7 from being erroneously mounted.

In the present embodiment, the drawer mechanism 640 is provided with the dial type display 649, but the reel holder 71 may be provided, for example, as shown in FIG. In addition to the dial-type display 649, the information notification unit shows the relationship between the attachment position of the feeder 5 and the holding position of the reel 7 on a member (for example, a magnet member) that can be attached to and detached from the drawer mechanism 640 and the reel holder 71. A display member or the like that displays information may be used. Further, the above information is not limited to numbers, but also includes characters and figures. Further, the applicable range of the information notification unit is not limited to the trolley 6 equipped with the feeder 5 having an auto-loading function, but can be applied to all component mounting devices that perform component mounting work while associating the feeder 5 and the reel 7. Is.

In the above-described embodiment, the width direction X corresponds to the "horizontal direction orthogonal to the delivery direction" of the present invention. Further, one of the pair of rail members 641 and 642 corresponds to an example of the "first moving body" of the present invention, and the other corresponds to an example of the "second moving body" of the present invention. Further, the ends 711b and 712b of the pair of side plates 711 and 712 on the (-Y) direction side correspond to an example of the "engaged end" of the present invention, and the ends of the pair of side plates 711 and 712 on the (+ Y) direction side. The ends 711c and 712c correspond to an example of the "engaged end" of the present invention.

The present invention is not limited to the above embodiment, and various modifications can be made to the above as long as it does not deviate from the gist thereof. Therefore, for example, in the first embodiment, only the second reel 7B is loaded on the additional reel holding portion 650. For example, as shown in FIG. 8, the partition plate 651 is additionally attached to and detachably attached to the additional reel holding portion 650. Also, this can regulate the movement of the second reel 7B in the width direction X. As a result, it is possible to prevent the second reel 7B from falling or coming off. In addition, the following effects can be obtained. That is, when the second reel 7B is not held at the desired holding position, for example, when the second reel 7B is loaded with a deviation of one, the second reel 7B is arranged in a line with the first reel 7A and the feeder 5 along the delivery direction Y. This may cause the tape 40 to be twisted. However, by mounting the partition plate 651 on the additional reel holding portion 650, the second reel 7B is held at an appropriate holding position, and the twisting can be reliably prevented. In addition, the partition plate 651 greatly contributes to the arrangement of the second reel 7B. The partition plate 651 may be installed by using the positioning slit of the additional reel holding portion 650, or may be installed by using a magnet. Of course, the partition plate 651 may be used exclusively for the additional reel holding portion 650, but the versatility of the partition plate 651 can be enhanced by sharing it with the standard reel holding portion 630.

Further, in the above embodiment, for example, as shown in FIGS. 4A and 4B, the X-direction size of the drawer mechanism 640 is substantially the same as that of the standard reel holding portion 630, but the X-direction size of the drawer mechanism 640 is arbitrary. .. Further, the drawer mechanism 640 may be divided into a plurality of parts so that they can be pulled out independently.

Further, in the second embodiment, the movement control unit 645 is added to the carriage 6 according to the first embodiment, but it may be applied to the third to fifth embodiments, and is the same as the second embodiment. The action effect of is obtained.

Further, in the above embodiment, the drawer mechanism 640 is added to the carriage 6 equipped with the feeder 5 having the auto-loading function, but only the feeder 5 having no auto-loading function is held by the feeder holding portion 660. The present invention can also be applied to the trolley 6.
