Description

[Technical field]

[0001] The present invention relates to a reel holding device and a dolly for holding a reel around which a carrier tape is wound. [Background technology]

[0002] In a component mounting device that mounts components on a board, a carrier tape that stores components is wound around a reel and placed on a cart equipped with a tape feeder that supplies components. As a type of tape feeder, an autoloading tape feeder is known that automatically pulls in a carrier tape whose tip has been inserted by an operator and feeds the components by pitch. The autoloading tape feeder can supply components without splicing the carrier tape by inserting the following carrier tape before the preceding carrier tape runs out of components.

[0003] In order to use such an autoloading tape feeder efficiently, it is necessary to install a reel on which the following carrier tape is wound in advance on a dolly. However, the space on a dolly that can hold reels is generally limited. Patent Document 1 discloses an expandable reel holding device that has multiple reel holding members that rotatably hold reels, can hold multiple reels simultaneously, and is detachable from a dolly. When there is a shortage of reel installation space on a dolly, the reel holding device of Patent Document 1 can be attached to the dolly to increase the number of reel installation spaces.

[0012] An embodiment of the present invention will be described in detail below with reference to the drawings. The configurations, shapes, etc. described below are illustrative examples and can be modified as appropriate according to the specifications of the component mounting device, the dolly, and the reel holding device. In the following, the same reference numerals are used for corresponding elements in all the drawings, and duplicated explanations will be omitted. In FIG. 1 and in some parts described later, the X-axis (perpendicular to the paper surface in FIG. 1) in the board transport direction and the Y-axis (left-right direction in FIG. 1) perpendicular to the board transport direction are shown as two axes perpendicular to each other in the horizontal plane. In FIG. 1 and in some parts described later, the Z-axis (up-down direction in FIG. 1) is shown as the height direction perpendicular to the horizontal plane.

[0013] 1 is an apparatus for mounting components PT on a board PB, and includes a base 11, a board transport unit 12, a component mounting unit 13, and a component supply unit 14. For ease of explanation, the back side as viewed from an operator OP is defined as the front, and the front side is defined as the rear.

[0014] In Fig. 1, the board transport section 12 is equipped with a pair of conveyors 12a extending in the X-axis direction on the base 11. The board transport section 12 supports the board PB from below with the pair of conveyors 12a and transports it in the X-axis direction. The component mounting section 13 moves a mounting head 13H equipped with a suction nozzle 13a in a horizontal plane direction by a head moving mechanism (not shown). The component supply section 14 of the component mounting device 1 is equipped with a carriage 15 connected to the base 11 and a plurality of tape feeders 16 attached to the carriage 15. A plurality of reels 18 that supply carrier tape 17 to each tape feeder 16 are set on the carriage 15 (see also Fig. 2).

[0015] Here, the structures of the carrier tape 17 and the reel 18 will be described with reference to FIG. 3. The carrier tape 17 has a base tape 21 and a cover tape 22. A plurality of components PT are stored in a line on the base tape 21. The cover tape 22 is attached to the upper surface of the base tape 21 to prevent each component PT from falling off the base tape 21. The carrier tape 17 is wound around the reel 18. The carrier tape 17 is pulled out from the reel 18 and fed into the tape feeder 16. A pin insertion hole 18H is provided in the center of the reel 18 so as to penetrate the reel 18 in the thickness direction. In this manner, the carrier tape 17 storing the components PT to be supplied to the tape feeder 16 is wound around the reel 18.

[0016] 1 and 2, tape feeder 16 is an autoload type tape feeder that pitch-feeds carrier tape 17 inserted at the rear end (the end on the operator OP side) while pulling it out from reel 18, and supplies components PT to component supply port 16K at the front end. Cover tape 22 attached to base tape 21 is peeled off during the pitch-feed by a peeling member (not shown) provided inside tape feeder 16, and is discharged to the outside of tape feeder 16 together with base tape 21.

[0017] 1 and 2, the cart 15 has a feeder base 15F and an operating handle 15H. The feeder base 15F has a plurality of slots 15S extending in the Y-axis direction and arranged side by side in the X-axis direction. In addition to a normal-sized tape feeder 16, a thin-sized tape feeder 16 (indicated by reference symbol 16U in FIG. 2) and a wide-sized tape feeder (not shown) are also attached to each slot 15S. Two thin-sized tape feeders 16 are attached side by side in one slot 15S. The wide-sized tape feeder is attached across multiple slots 15S.

[0018] The dolly 15 moves on the floor surface YK by operating the operating handle 15H by the operator OP, and is coupled to the base 11 of the component mounting apparatus 1. When the dolly 15 is coupled to the base 11, the component supply port 16K of each tape feeder 16 attached to the feeder base 15F is positioned at a specified position (component supply position) within the component mounting apparatus 1.

[0019] 4, a first rod 31, a second rod 32, and a third rod 33 are provided inside the carriage 15 (the space below the feeder base 15F) and extend in the X-axis direction. The second rod 32 is located below and rearward of the first rod 31. The third rod 33 is located above and rearward of the second rod 32.

[0020] A plurality of upper reel holders 34 are attached to the first rod 31 and lined up in the X-axis direction. The upper reel holders 34 correspond one-to-one to the slots 15S, and are provided below the corresponding slots 15S. A plurality of lower reel holders 35 are attached to the second rod 32 and lined up in the X-axis direction. Like the upper reel holders 34, the lower reel holders 35 correspond one-to-one to the slots 15S, and are provided below the corresponding slots 15S (and further below the corresponding upper reel holders 34).

[0021] 2 and 4, each upper reel holder 34 can be raised and lowered (swinged) about the first rod 31 as an axis, and in a lying-down position with its free end (rear end) lowered, it rotatably holds (supports) one small diameter reel 18 (referred to as small diameter reel 18A). Each lower reel holder 35 can be raised and lowered (swinged) about the second rod 32 as an axis, and in a standing-up position with its free end (rear end) raised, it rotatably holds (supports) one small diameter reel 18A.

[0022] The lower reel holder 35 also rotatably holds one large diameter reel 18 (referred to as large diameter reel 18B). At this time, the lower reel holder 35 holds the lower end of the lower reel holder 35 in a lying position with its free end (rear end) abutting against the third rod 33 from above.

[0023] As described above, reel 18 is rotatably held by upper reel holder 34 or lower reel holder 35 inside dolly 15. Carrier tape 17 is pulled out from each reel 18 held inside dolly 15 and inserted into tape feeder 16 located above it (FIGS. 1 and 2).

[0024] In the component mounting apparatus 1 configured as described above, the autoload tape feeder 16 requires installation space for two reels 18, including the standby reel 18. When one autoload tape feeder 16 is attached to one slot 15S, two reels 18 are required per slot 15S. When the small diameter reel 18A is used, the upper reel holder 34 and the lower reel holder 35 can ensure installation space for the reels 18, including the standby reel 18. However, when the large diameter reel 18B is used or when two thin tape feeders 16 are attached to one slot 15S, the installation space for the reels 18 is insufficient.

[0025] For this reason, in the component mounting apparatus 1 of this embodiment, a reel holding device 40 as a mounting location for the reel 18 is attached externally to the cart 15, and the small diameter reel 18A and the large diameter reel 18B can be held freely rotatably on the externally attached reel holding device 40 (Figures 1 and 2).

[0026] Next, the structure of reel holding device 40 will be described with reference to Figures 5 and 6. Reel holding device 40 is configured to have an attachment part 41 attached to dolly 15, and an arm part 42 extending diagonally upward and rearward from the rear end part of attachment part 41 attached to dolly 15.

[0027] The arm portion 42 is a member formed in a plate shape as a whole, and has a long trunk portion 42a that extends obliquely upward when attached to the attachment portion 41, and a support portion 42b that extends rearward from the trunk portion 42a. An engagement slit 42S that opens to the outer periphery of the lower end portion 42c is formed in the lower end portion 42c of the trunk portion 42a. As described later, a reel holding member 43 that holds the reel 18 rotatably is attached to a predetermined position of the arm portion 42. The reel 18 is attached to the arm portion 42 so that the reel holding member 43 is inserted into the pin insertion hole 18H. A thin flange 43F is formed at the tip of the reel holding member 43 to prevent the attached reel 18 from falling off.

[0028] In FIG. 6(a) and FIG. 6(b), the trunk 42a of the arm 42 has a plurality of pin attachment holes 42H penetrating the arm 42 in the thickness direction. In this embodiment, one pin attachment hole 42H is provided at the tip of the trunk 42a and another at the base of the trunk 42a. In the support portion 42b of the arm 42, a plurality of support slits 42N that open substantially upward are formed on the outer periphery of the support portion 42b. In this embodiment, one support slit 42N (upper support slit 42N1) is formed at a high position of the support portion 42b, and one support slit 42N (lower support slit 42N2) is formed at a position lower and rearward than the upper support slit 42N1. That is, the two support slits 42N are disposed at positions offset in the Y-axis direction (front-rear direction) and the Z-axis direction (up-down direction).

[0029] The reel holding member 43 can be attached at any position selected from among the multiple pin attachment holes 42H and the multiple support slits 42N. The attachment position of the reel holding member 43 relative to the arm portion 42 and the number and type of the reel holding members 43 attached to the arm portion 42 are changed according to the diameter (small diameter reel 18A, large diameter reel 18B) and width of the reel 18 to be held by the reel holding member 43 (see FIG. 15). In this manner, the arm portion 42 has a support portion 42b in which multiple support slits 42N are formed to support the reel holding member 43 that rotatably holds the reel 18. FIG. 5 shows a state in which the reel holding members 43 are attached to the right and left of the two pin attachment holes 42H.

[0030] 5 and 6, the attachment part 41 has an arm part holding part 41H at the center of the rear end in the X-axis direction that detachably holds the arm part 42 (arrow a). The arm part holding part 41H is formed in the attachment part 41 and includes a gap 41G into which the lower end part 42c of the arm part 42 is inserted, and a plurality of (here, two) pins 41P arranged in the gap 41G.

[0031] When the lower end 42c of the arm portion 42 is inserted into the arm portion holding portion 41H, the engagement slits 42S of the lower end 42c engage with the multiple pins 41P. Also, the outer periphery of the lower end 42c abuts against the inner wall of the gap 41G (FIG. 6(a)). When the arm portion 42 rotates due to gravity, a force is generated that presses the engagement slits 42S against the multiple pins 41P and a force is generated that presses the outer periphery of the lower end 42c against the gap 41G. This force (friction force) causes the arm portion 42 to be held by the arm portion holding portion 41H.

[0032] 5 and 6, a first concave engagement portion 41A is provided on the upper surface of the front end side of the attachment portion 41. A second concave engagement portion 41B is provided on the lower surface between the front end and the rear end of the attachment portion 41. The first engagement portion 41A is adapted to be engaged with the second rod 32 of the dolly 15 from below. The second engagement portion 41B is adapted to be engaged with the third rod 33 of the dolly 15 from above. By engaging the first engagement portion 41A with the second rod 32 and engaging the second engagement portion 41B with the third rod 33, the reel holding device 40 is held on the underside of the dolly 15 (see FIGS. 1 and 2).

[0033] In this manner, the reel holding device 40 is detachably attached to the carriage 15 on which the tape feeder 16 is provided. In addition, the multiple reel holding devices 40 are arranged on the carriage 15 along the rotation axis (X-axis direction) of the reel 18.

[0034] Next, with reference to Figs. 7 to 11, an example of holding various reels 18 in the reel holding device 40 will be described. Fig. 7 shows an example of holding four small diameter reels 18A in the reel holding device 40. Reel holding members 43 are attached to the right and left sides of two pin attachment holes 42H in the arm portion 42. That is, four reel holding members 43 are attached to the arm portion 42. Each reel holding member 43 can hold a small diameter reel 18A. That is, two small diameter reels 18A are held on the right side of the arm portion 42, and two small diameter reels 18A are held on the left side.

[0035] 8 shows an example in which two large diameter reels 18B are held by the reel holding device 40. A reel holding member 43 is attached to the arm portion 42 on the left side of the upper support slit 42N1 and on the right side of the lower support slit 42N2. That is, two reel holding members 43 are attached to the arm portion 42. Each of the reel holding members 43 can hold a large diameter reel 18B.

[0036] That is, one large diameter reel 18B is held on the right side of the arm portion 42, and one large diameter reel 18B is held on the left side. Since the positions of the upper support slits 42N1 and the lower support slits 42N2 are offset front-to-back and up-down, it becomes easy for the operator OP to replace the large diameter reel 18B held by the reel holding device 40 (see also FIG. 15).

[0037] Figures 9 and 10 show an example in which a detachable reel holding member 43A is attached to the support slit 42N of the arm portion 42. Figure 10(a) shows a state in which the reel holding members 43A are attached to the left side of the upper support slit 42N1 and to the right side of the lower support slit 42N2 of the arm portion 42. Figure 10(b) shows an enlarged cross section of the area including the upper support slit 42N1 and the lower support slit 42N2, indicated by the rectangle c in Figure 10(a).

[0038] In the reel holding member 43A, a groove 43AS that engages with the support slit 42N is formed in the end 43AT on the side attached to the arm portion 42. A flange 43AF is formed on the side opposite to the end 43AT of the reel holding member 43A. The reel holding member 43A is attached to and detached from the arm portion 42 so that the groove 43AS is aligned with the support slits 42N (upper support slit 42N1, lower support slit 42N2) (arrow b in FIG. 9). That is, the support slit 42N engages with the groove 43AS formed in the end 43AT of the reel holding member 43A to support the reel holding member 43A. The support portion 42b of the arm portion 42 is capable of attaching and detaching the reel holding member 43A in a state in which the reel 18 is being held.

[0039] Fig. 11 shows an example in which one large diameter wide reel 18C that is large in diameter and wide is held by the reel holding device 40. Fig. 11(b) shows an enlarged cross section of the area including the upper support slit 42N1 and the lower support slit 42N2, shown by the rectangle d in Fig. 11(a). When holding the large diameter wide reel 18C, two adjacent reel holding devices 40 arranged on the dolly 15 are used. In addition, a reel holding member 43B is used, in which grooves 43BS are formed at both ends 43BT, respectively, and which is longer than the width of the large diameter wide reel 18C to be held.

[0040] Specifically, first, the pin insertion hole 18H is inserted into the reel holding member 43B to make the reel holding member 43B hold the large diameter wide reel 18C. Next, the groove 43BS of the reel holding member 43B holding the large diameter wide reel 18C is engaged with the upper support slit 42N1 or the lower support slit 42N2 of the arm parts 42 of the two adjacent reel holding devices 40 to support the reel. That is, in the dolly 15, the support parts 42b of the two adjacent reel holding devices 40 support one reel holding member 43B. FIG. 11 shows an example in which the reel holding member 43B is supported by the lower support slit 42N2.

[0041] 12 to 14, the detailed configurations of reel holding member 43A for thin reels such as small diameter reel 18A and large diameter reel 18B, reel holding member 43B for wide reels such as large diameter wide reel 18C, and reel holding member 43C for very wide reels such as large diameter very wide reel 18D (see FIG. 15) will be described. Reel holding members 43A, 43B, 43C are formed by combining components such as screw 50, nut 51, axle 52, and screw 53.

[0042] FIG. 12 shows the configuration of a reel holding member 43A for a thin reel. The reel holding member 43A is configured by combining two screws 50, one nut 51, and one spindle 52. The screw 50 has a head 50a, a small diameter portion 50b formed on one side of the head 50a and having a smaller diameter than the head 50a, and a male thread portion 50c extending from the small diameter portion 50b. The nut 51 has a large diameter portion 51a having approximately the same diameter as the head 50a of the screw 50, and a small diameter portion 51b formed on one side of the large diameter portion 51a and having approximately the same diameter as the small diameter portion 50b of the screw 50. In addition, a female thread portion 51c that is coupled to the male thread portion 50c of the screw 50 is formed in the center of the nut 51. The spindle 52 is cylindrical, and a female thread portion 52a that is coupled to the male thread portion 50c of the screw 50 is formed in the center.

[0043] In Figure 12(a), the reel holding member 43A is configured by abutting the surface opposite the small diameter portion 51b of the nut 51 against one end of the mandrel 52, screwing the male threaded portion 50c of the screw 50 into the female threaded portion 51c of the nut 51 and the female threaded portion 52a of the mandrel 52, and screwing another screw 50 into the other end of the mandrel 52.

[0044] 12(b), the screw 50 and nut 51 on one end side of the shaft 52 of the reel holding member 43A form an end portion 43AT. The space surrounded by the head 50a and small diameter portion 50b of the screw 50 and the small diameter portion 51b and large diameter portion 51a of the nut 51 forms a groove 43AS that engages with the support slit 42N of the arm portion 42. That is, the diameter of the small diameter portions 50b, 51b is smaller than the width of the support slit 42N, and the diameters of the head 50a and large diameter portion 51a are larger than the width of the support slit 42N. The head 50a of the screw 50 on the other end side of the shaft 52 forms a flange 43AF of the reel holding member 43A.

[0045] 13 shows the configuration of reel holding member 43B for wide reels. Reel holding member 43B is composed of two screws 50, two nuts 51, two axles 52, and one screw 53. Screw 53 is cylindrical, with male screw portion 53a formed on the outer periphery that engages with female screw portion 52a of axle 52, and hexagonal holes 53b formed on both end faces.

[0046] In Fig. 13(a), the reel holding member 43B is formed by screwing half of the male threaded portion 53a of a screw 53 into the female threaded portion 52a of the axle 52, and screwing the female threaded portion 52a of another axle 52 into the remaining male threaded portion 53a, thereby joining two axles 52. The reel holding member 43B is formed by attaching a nut 51 and a screw 50 to each end of the joined axles 52. In Fig. 13(b), the screws 50 and nuts 51 at both ends of the reel holding member 43B form an end portion 43BT having a groove 43BS.

[0047] 14 shows the configuration of a reel holding member 43C for a very wide reel. The reel holding member 43C is configured by combining two screws 50, two nuts 51, three axles 52, and two screws 53.

[0048] In Fig. 14(a), the reel holding member 43C has three axles 52 joined together with two screws 53. The reel holding member 43C is formed by attaching a nut 51 and a screw 50 to each end of the joined axles 52. In Fig. 14(b), the screws 50 and nuts 51 at both ends of the reel holding member 43C form an end 43CT having a groove 43CS.

[0049] In this way, the reel holding members 43A-43C of the present embodiment can be configured to have various lengths by changing the combination of the components (screws 50, nuts 51, axles 52, and screws 53). This allows the necessary reel holding members 43A-43C to be quickly prepared at the production site when the type or number of reels 18 used in the component mounting apparatus 1 is changed.

[0050] Next, referring to Fig. 15, an example in which multiple reel holding devices 40 are arranged on a cart 15 to hold a variety of reels 18 will be described. Figs. 15(a) and 15(b) show a schematic diagram of a portion of a cart 15 on which multiple reel holding devices 40 are arranged, as viewed from an operator OP. Here, the reel holding devices 40 arranged on the cart 15 are referred to as reel holding device 40(1), reel holding device 40(2), etc., from left to right.

[0051] 15(a), reel holding devices 40(1) to 40(3) have reel holding members 43 attached to the right and left of two pin attachment holes 42H of the arm portion 42, and each reel holding member 43 holds a small diameter reel 18A. Reel holding device 40(4) has reel holding members 43 attached to the left of the upper support slit 42N1 and to the right of the lower support slit 42N2 of the arm portion 42, and each reel holding member 43 holds a large diameter reel 18B. Reel holding device 40(5) has reel holding member 43A attached to the left of the upper support slit 42N1 of the arm portion 42, and the large diameter reel 18B is held by reel holding member 43A.

[0052] A reel holding member 43B that holds the large diameter wide reel 18C is supported in the lower support slits 42N2 of the reel holding devices 40(5) and 40(6), and the reel holding devices 40(7) and 40(8). A reel holding member 43B that holds the large diameter wide reel 18C is supported in the upper support slits 42N1 of the reel holding devices 40(6) and 40(7). In other words, three large diameter wide reels 18C are held between the reel holding devices 40(5) and 40(8), offset front to back and up and down.

[0053] 15(a), a reel holding member 43C that holds a large diameter, very wide reel 18D that is wider than the large diameter, wide reel 18C is supported in the upper support slit 42N1 of the reel holding device 40(8) and the reel holding device 40(9). A reel holding member 43C that holds a large diameter, very wide reel 18D that is wider than the large diameter, wide reel 18C is supported in the lower support slit 42N2 of the reel holding device 40(9) and the reel holding device 40(10). In other words, two large diameter, very wide reels 18D are held offset front to back and up and down between the reel holding device 40(8) and the reel holding device 40(10).

[0054] The carrier tape 17 wound around each reel 18 (small diameter reel 18A, large diameter reel 18B, large diameter wide reel 18C, large diameter very wide reel 18D) is fed to the tape feeder 16 attached to the cart 15. In this manner, a plurality of reel holding devices 40 are arranged on the cart 15, and various reels 18 (small diameter reel 18A, large diameter reel 18B, large diameter wide reel 18C, large diameter very wide reel 18D) are held without gaps. Therefore, the reel 18 (small diameter reel 18A) held by the lower reel holder 35 of the cart 15 and the reels 18 (large diameter reel 18B, large diameter wide reel 18C, large diameter very wide reel 18D) held directly by the cart 15 are hidden by the reels 18 held by the reel holding devices 40 when viewed from the operator OP.

[0055] 15(b), a description will be given of the work of replacing a reel 18 hidden by a reel 18 held by reel holding device 40. Here, an example will be described in which small diameter reels 18A1, 18A2 located at the back of reel holding device 40(2) are replaced with large diameter wide reel 18C1 located at the back between reel holding device 40(6) and reel holding device 40(7).

[0056] First, an example of a reel replacement operation when the carrier tape 17 of the small diameter reel 18A1 held by the upper reel holder 34 runs out will be described. The operator OP removes the arm unit 42 holding the four small diameter reels 18A from the attachment unit 41 of the reel holding device 40(2). At that time, the operator OP moves the arm unit 42 to a position that does not interfere with the replacement operation of the small diameter reels 18A1, 18A2, while leaving the carrier tape 17 wound around the four small diameter reels 18A held by the arm unit 42 fed into the tape feeder 16.

[0057] 15(b), the operator OP removes the empty small diameter reel 18A1 from the upper reel holder 34, and moves the small diameter reel 18A2, which is supplying the carrier tape 17 held in the lower reel holder 35, to the now vacant upper reel holder 34. Then, a new small diameter reel (not shown) for refilling is placed in the lower reel holder 35, and the carrier tape 17 of the small diameter reel for refilling is inserted into the tape feeder 16 that is using the carrier tape 17 unwound from the small diameter reel 18A2. When the reel replacement work is completed, the arm portion 42 holding the four small diameter reels 18A is held in the attachment portion 41 of the reel holding device 40(2) in its original position.

[0058] Next, an example of a reel replacement operation when the carrier tape 17 of the large diameter wide reel 18C1 directly held by the dolly 15 runs out will be described. In Fig. 15(b), the operator OP removes the reel holding member 43B holding the large diameter wide reel 18C supported by the arm portion 42 from between the reel holding device 40(6) and the reel holding device 40(7). At that time, the operator OP moves the reel holding member 43B holding the large diameter wide reel 18C to a position that does not interfere with the replacement operation of the small diameter reel 18A1, while leaving the carrier tape 17 wound around the large diameter wide reel 18C held by the reel holding member 43B fed into the tape feeder 16.

[0059] In FIG. 15(b), the operator OP then removes the empty large-diameter wide reel 18C1 from the cart 15. Next, the operator OP removes the reel holding member 43B from the retreated large-diameter wide reel 18C and moves it to the position vacant after the large-diameter wide reel 18C1 was removed. Then, the operator OP inserts the reel holding member 43B into the pin insertion hole 18H of a new large-diameter wide reel (not shown) for replacement. Then, the reel holding member 43B holding the replacement large-diameter wide reel is supported by the reel holding device 40(6) and the arm portion 42 of the reel holding device 40(7) in their original positions. Next, the operator inserts the carrier tape 17 of the replacement large-diameter wide reel into the tape feeder 16 that uses the carrier tape 17 unwound from the large-diameter wide reel 18C. This completes the reel replacement operation.

[0060] In this way, the reel holding device 40 of the present embodiment can easily attach and detach the arm portion 42 and the reel holding members 43A, 43B, and 43C while holding the reel 18. Therefore, it is possible to replace another reel 18 held by the lower reel holder 35 of the dolly 15 or the like without removing the carrier tape 17 wound around the reel 18 from the tape feeder 16. In addition, when replacing the reel 18 itself held by the arm portion 42 and the reel holding members 43A, 43B, and 43C, the work can be easily performed by removing the arm portion 42 and the reel holding members 43A, 43B, and 43C from the reel holding device 40.

[0061] As described above, the reel holding device 40 of this embodiment has the attachment part 41 attached to the dolly 15, and the arm part 42 extending from the attachment part 41. The arm part 42 has the support part 42b that supports the reel holding members 43A, 43B, 43C that rotatably hold the reel 18, and the support part 42b is detachable from the reel holding members 43A, 43B, 43C that are holding the reel 18. This allows the reel 18 to be easily replaced.

[0062] Another reel holding device 40 of this embodiment has an attachment part 41 that is attached to the dolly 15, and an arm part 42 that extends from the attachment part 41. The attachment part 41 has an arm part holding part 41H that detachably holds the arm part 42. This makes it easy to replace the reel 18. [Industrial Applicability]

[0063] The reel holding device and the carriage of the present invention have the effect of enabling the reel replacement operation to be easily performed, and are useful in the field of mounting components on a circuit board. [Explanation of symbols]
