[Technical Field]

[0001] The present disclosure relates to a reel holding device that holds a reel around which a carrier tape containing components to be supplied to a tape feeder is wound, and a component mounting device that includes this reel holding device. [Background technology]

[0002] Conventionally, component mounting devices that use a mounting head to pick up components and mount them on a board are known, and tape feeders are often used as component supply devices in such component mounting devices. Tape feeders are configured to supply components to a component removal position by transporting a carrier tape containing components using a tape transport unit. The carrier tape is supplied to the tape feeder in a state wound around a reel, and a feeder cart on which the tape feeder is mounted is provided with a reel holder (tape reel storage unit) that rotatably holds the reel (see, for example, Patent Document 1 below).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-60232 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned conventional reel holding device, if the carrier tape wound around the reel is unwound close to its end and the end of the carrier tape cannot easily be separated from the winding core of the reel, the tensed carrier tape will pull the reel out of the reel holder and cause it to fall off, and in the worst case scenario, the entire reel will be pulled up by the carrier tape and come into contact with the tape feeder, which could damage the tape feeder.

[0005] Therefore, an object of the present disclosure is to provide a reel holding device and a component mounting device that can prevent a situation in which a reel is pulled out of a reel holder by a tensed carrier tape. [Means for solving the problem]

[0006] The reel holding device of the present disclosure is a reel holding device that holds a reel wound with a carrier tape that contains components to be supplied to a tape feeder, and includes a reel holder that receives the reel inserted through a reel insertion port that opens upward and holds it rotatably, a guide member that guides the carrier tape that is unwound from the reel held in the reel holder, and a guide member support portion that supports the guide member so that it can move freely in the vertical direction, and when the carrier tape pulled in by the tape feeder is not tensioned, the guide member is located at a first position that guides the carrier tape that is unwound from the reel so that it faces in a direction that is not toward the tape feeder, and when the carrier tape is pulled by the tape feeder and becomes tensioned, the guide member is located at a second position that prevents the reel from being pulled out of the reel holder by the tensioned carrier tape.

[0007] In addition, the component mounting device of the present disclosure includes the reel holding device of the present disclosure, a tape feeder that pulls in the carrier tape unwound from the reel held by the reel holding device to supply components, and a mounting head that picks up the components supplied by the tape feeder and mounts them on a substrate. [Effects of the Invention]

[0010] Hereinafter, with reference to the accompanying drawings, detailed descriptions of embodiments that specifically disclose the configuration and operation of a printing device and a printing method according to the present disclosure will be provided. However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure and are not intended to limit the subject matter recited in the claims.

[0011] Fig. 1 is a side view of a main portion of a component mounting apparatus 1 according to an embodiment of the present disclosure. Fig. 1 shows the component mounting apparatus 1 according to an embodiment of the present disclosure. The component mounting apparatus 1 is an apparatus that performs a component mounting operation of mounting components BH onto a board KB that has been brought in from outside, and includes a mounting apparatus main body 2 that mounts the components BH onto the board KB, and a component supply unit 3 that supplies the components BH to the mounting apparatus main body 2. Hereinafter, the direction in which the board KB is transported in the component mounting apparatus 1 (the left-right direction as seen from the operator OP) will be referred to as the X direction, the horizontal direction perpendicular to the X direction (the front-rear direction as seen from the operator OP) will be referred to as the Y direction, and the up-down direction will be referred to as the Z direction.

[0012] In Figure 1, the mounting device main body 2 has a substrate transport unit 12 mounted on a base 11. The substrate transport unit 12 is made up of a pair of conveyor mechanisms arranged opposite each other in the Y direction and transports the substrate KB in the X direction. A mounting head 13 is arranged above the base 11. The mounting head 13 has multiple nozzles 13N extending downward and is moved horizontally by a head moving unit 14, which is made up of, for example, an XY beam mechanism. The mounting head 13 can generate a vacuum suction force at the bottom end of each nozzle 13N.

[0013] 1, the component supply unit 3 is equipped with a feeder cart 21 and a plurality of tape feeders 22. The feeder cart 21 is equipped with a plurality of wheels 31, and is movable along the floor surface FL and connected to the base 11 of the mounting device main body 2. A block-shaped feeder base 32 is provided on the upper part of the feeder cart 21. An upper reel holding unit 33 and a lower reel holding unit 34 are provided on the front side of the feeder base 32 as seen from the operator OP (hereinafter simply referred to as the "front side").

[0014] Fig. 2 is a side view of a portion of component mounting device 1 according to an embodiment of the present disclosure. Tape feeder 22 functions as a component supply device, and as shown in Figs. 1 and 2, is mounted on the upper surface of feeder base 32. Multiple tape feeders 22 can be mounted on feeder base 32 and lined up in the X direction.

[0015] 2, tape feeder 22 includes tape transport unit 22H therein. Tape feeder 22 transports carrier tape CT toward the rear side as seen from operator OP (hereinafter simply referred to as the "rear side") using tape transport unit 22H. Components BH are stored one by one at regular intervals on carrier tape CT, and when tape transport unit 22H transports carrier tape CT intermittently (pitch transport), components BH are sequentially positioned at component removal position 22T set at the rear end of tape feeder 22.

[0016] 1 and 2, a reel RL around which a carrier tape CT is wound is held by each of the upper reel holding portion 33 and the lower reel holding portion 34. Hereinafter, the reel RL held by the upper reel holding portion 33 will be referred to as the "upper reel RL1," and the reel RL held by the lower reel holding portion 34 will be referred to as the "lower reel RL2."

[0017] 1 and 2, a tape loading section 22L is provided on the front side of tape feeder 22. Upper reel RL1 and lower reel RL2 correspond to tape feeder 22 attached to feeder base 32 and are set in positions directly below tape loading section 22L that tape feeder 22 includes.

[0018] 3 is a side view of an upper reel holding unit 33 provided in the component mounting device 1 according to an embodiment of the present disclosure. In FIG. 3 (which is an enlarged view of an area AR in FIG. 2), the tape loading unit 22L has a current-side insertion unit 22a into which a current tape CTC, which is a carrier tape CT to be transported, is inserted, and a next-side insertion unit 22b into which a next tape CTN, which is a refill carrier tape CT, is inserted. The carrier tape CT pulled out from the upper reel RL1 is inserted into the current-side insertion unit 22a, and the carrier tape CT pulled out from the lower reel RL2 is inserted into the next-side insertion unit 22b (see also FIG. 2).

[0019] The carrier tape CT has its end portion simply attached to the winding core portion (FIG. 3) of the reel RL, and when the end portion of the current tape CTC being fed by the tape feeder 22 reaches the winding core portion MS of the upper reel RL1, the end portion of the current tape CTC is detached from the winding core portion MS of the upper reel RL1. Thereafter, the tape feeder 22 continues to feed the current tape CTC until it has finished feeding it to the end portion, at which point the current tape CTC runs out of components. When the tape feeder 22 runs out of components, it moves the carrier tape CT inserted in the next-side insertion portion 22b to the current-side insertion portion 22a, feeds the carrier tape CT that was previously the next tape CTN as the next current tape CTC, and continues the component supply operation (details will be described later).

[0020] When the component mounting device 1 configured as described above performs a component mounting operation of mounting components BH on a board KB, the board transport unit 12 first operates to carry in the board KB supplied from outside the component mounting device 1 and position it at a predetermined work position. Once the board KB is positioned at the work position, the tape feeder 22 transports the carrier tape CT to supply the components BH to the component removal position 22T. The mounting head 13 is moved by the head moving unit 14, picks up the components BH supplied by the tape feeder 22 by suction, and then moves above the board KB to repeatedly perform the component mounting operation of mounting the components BH onto the board KB.

[0021] When all of the components BH to be mounted on the board KB have been mounted by repeating the component mounting operation of the mounting head 13, the board transport unit 12 operates to transport the board KB out of the component mounting device 1. This completes the component mounting operation for one board KB.

[0022] In this embodiment, in the component mounting device 1 having such a configuration, the upper reel holding section 33 serving as a reel holding device has a distinctive configuration, which will be described below.

[0023] Fig. 4 is a perspective view of the upper reel holding portion 33 according to one embodiment of the present disclosure. Fig. 4 shows the upper reel holding portion 33 together with the reel RL (upper reel RL1) held therein. As shown in Fig. 4, the upper reel holding portion 33 includes a plurality of reel holders 41, guide members 42, and guide member supports 43 arranged side by side in the X direction.

[0024] Fig. 5 is a perspective view of a reel holder 41 provided in an upper reel holding portion 33 according to an embodiment of the present disclosure. In Figs. 4 and 5, each reel holder 41 is configured to include a pair of side plates 51 that extend in the front-to-rear direction as a whole and are arranged facing each other in the X direction, and two front and rear spacers 52 that connect the front and rear (rear and front) ends of the side plates 51, respectively. The two side plates 51 and the two spacers 52 form a frame that is approximately rectangular in plan view and is elongated in the front-to-rear direction, and the top opening of the frame serves as a reel insertion slot 41S into which a reel RL is inserted from above (Figs. 4 and 5).

[0025] The distance between the two side plates 51 of the reel holder 41 is slightly larger than the thickness dimension of the reel RL, and the distance between the two spacers 52 is slightly smaller than the diameter of the reel RL. Therefore, when the reel RL is inserted through the reel insertion opening 41S, its side surface (the surface facing the X direction) is guided by the two side plates 51, and its circular outer periphery is supported by the two front and rear spacers 52. Therefore, the reel RL received in the reel holder 41 can rotate in place (spin on its own axis) while being supported by the two spacers 52.

[0026] As described above, in this embodiment, the reel holder 41 is configured to receive the reel RL inserted through the reel insertion opening 41S that opens upward, and to hold the reel RL rotatably.

[0027] 4 and 5, a long hole-shaped guide groove 51H extending along the longitudinal direction of the side plate 51 is formed in the rear region of each of the pair of side plates 51 constituting the reel holder 41 (see also FIG. 3). A shaft member 54 extending in the X direction and supported at both ends by the feeder cart 21 is provided to pass through these two guide grooves 51H. Therefore, the reel holder 41 can swing freely in the YZ plane with the shaft member 54 as a support axis, and can rise and fall in the YZ plane so that the front end portion moves up and down.

[0028] 3 and 4, a rod-shaped upper stopper 55 is provided above the shaft member 54, and a similarly rod-shaped lower stopper 56 is provided below the shaft member 54. The upper stopper 55 is located above the upper edge of the reel holder 41, and the lower stopper 56 is located below the lower edge of the reel holder 41. Both ends of the upper stopper 55 and the lower stopper 56 are supported by the feeder cart 21, similar to the shaft member 54, and extend parallel to the shaft member 54.

[0029] The upper stopper 55 and the lower stopper 56 function to restrict the range of movement of the reel holder 41 in the up-down direction, which swings about the shaft member 54 as a support shaft. Specifically, the upper stopper 55 restricts the range of movement of the reel holder 41 in the up-down direction (the direction in which the front end is raised), and the lower stopper 56 restricts the range of movement of the reel holder 41 in the down-down direction (the direction in which the front end is lowered). However, in this embodiment, the reel holder 41 is not raised or lowered, but its lower edge abuts against the lower stopper 56 from above to maintain its down-down position (a diagonal position descending from the back side to the front side) (FIGS. 3 and 4).

[0030] 4, the guide member 42 is made of a rod-shaped member extending in the X direction and has a length that covers the entire area of ​​the multiple reel holders 41 lined up in the X direction. The X direction, which is the direction in which the guide member 42 extends, is the direction in which the multiple reel holders 41 are lined up, and is also a direction that is approximately perpendicular to the direction in which the carrier tape CT unwound from the reel RL held by the reel holder 41 extends.

[0031] That is, in this embodiment, the guide member 42 is made up of a rod-shaped member extending in a direction (X direction) substantially perpendicular to the direction in which the carrier tape CT unwound from the reel RL held by the reel holder 41 extends.

[0032] As shown in Figure 4, the guide member support portion 43 is configured with a pair of arm members 61 positioned to sandwich the reel holder 41 from both sides, and a pair of hanging members 62 provided on each of the pair of arm members 61 (see also Figure 6).

[0033] 4, the pair of arm members 61 are formed by using two reel holders 41 located at both ends of the multiple reel holders 41 lined up in the X direction as the arm members 61. Here, the arm members 61 are not used as the reel holders 41, but are used exclusively as the arm members 61 (therefore, the arm members 61 are members different from the reel holders 41, i.e., members separate from the reel holders 41).

[0034] In this embodiment, the pair of arm members 61 is composed of two reel holders 41 that are located at both ends of the plurality of reel holders 41 lined up in the X direction and are not used as reel holders 41, so that the pair of arm members 61 is positioned so as to sandwich the entire plurality of reel holders 41 lined up in the X direction from both sides.

[0035] As described above, each of the pair of arm members 61 utilizes a portion of the multiple reel holders 41 aligned in the X direction. Similar to the reel holder 41 described above, the pair of arm members 61 can swing freely within the YZ plane, with the shaft member 54 extending in the X direction as a support shaft, to move the front end portion up and down. The upper stopper 55 restricts the swing range of the up-and-down side, which raises the front end portion, and the lower stopper 56 restricts the swing range of the down-and-down side, which lowers the front end portion. In normal operation, when the carrier tape CT is not tensed, the lower edge of the arm member 61 abuts against the lower stopper 56 from above, thereby assuming a diagonal posture that descends from the rear to the front, similar to the reel holder 41 ( FIGS. 3 and 4 ).

[0036] FIG. 6 is a perspective view of a portion of the guide member support portion 43 and the guide member 42 provided in the upper reel holding portion 33 according to an embodiment of the present disclosure. In FIGS. 4 and 6, each of the pair of hanging members 62 is composed of a ring-shaped band member 71 and a block-shaped collar member 72, and supports the guide member 42 in a suspended state in which it hangs down under its own weight. The band member 71 is a member that supports the end of the guide member 42 extending in the X direction, and is hung across the front spacer 52 of the front and rear (rear and front) spacers 52 that make up the arm member 61, allowing it to swing freely (freely swing within a plane along the YZ plane). The collar member 72 is interposed inside the band member 71 between the front spacer 52 and the guide member 42.

[0037] Thus, in this embodiment, the guide member support portion 43 is composed of a pair of arm members 61 positioned on either side of the reel holder 41, and a pair of hanging members 62 that are freely swingable relative to the tip ends of the pair of arm members 61 and support both ends of the guide member 42 in a hanging state where they hang down by their own weight from the tip ends of the pair of arm members 61.

[0038] In this embodiment, each of the pair of hanging members 62 is configured to be detachable from the arm member 61. Specifically, hook-and-loop fasteners (not shown) are attached to both ends of the ring-shaped band member 71, and these two hook-and-loop fasteners are joined together to form a ring shape. Because the hanging members 62 are configured to be detachable from the arm member 61 in this way, in this embodiment, the hanging members 62 can be replaced with ones of different lengths, and the distance between the tip of the arm member 61 and the guide member 42 can be changed to a desired length.

[0039] 2, the lower reel holding section 34 is provided with reel guides 80 that rotatably hold the reels RL. A plurality of reel guides 80 are arranged side by side in the X direction. Like the reel holders 41 of the upper reel holding section 33, each reel guide 80 corresponds to one of the plurality of slots provided in the feeder base 32, and is provided in a position directly below the corresponding slot (a position further below the reel holders 41).

[0040] 2, each reel guide 80 is composed of a lower guide portion 81 and a rear guide portion 82. In each reel guide 80, the lower guide portion 81 is disposed in a position that slopes slightly downward from the front side toward the rear side. The front end (lower end) of the rear guide portion 82 is connected to the rear end of the lower guide portion 81, and the rear end (upper end) is disposed in a position that slopes toward the rear side. In other words, the lower guide portion 81 and the rear guide portion 82 are disposed so that they form a V-shape as a whole in the YZ plane.

[0041] The reel RL set in each reel guide 80 of the lower reel holding section 34 is held so as to abut against both the lower guide section 81 and the rear guide section 82, which are arranged in a V-shape as described above. The rear guide section 82 is formed in a groove shape with the X direction as its width direction, and prevents the reel RL from tipping sideways (in the X direction).

[0042] As described above, when the carrier tape CT is not tensioned, the pair of arm members 61 are in a diagonal position, descending from the rear side toward the front side ( FIG. 3 ). In this state, the guide member 42 hangs down under its own weight at a position below the front spacer 52 and contacts the carrier tape CT unwound from the upper reel RL1 toward the front side (pulled out by the tape feeder 22) from above, pressing down that portion. As a result, the carrier tape CT unwound from the reel RL is oriented downward rather than horizontally. In contrast, the carrier tape CT generates tension when pressed down by the guide member 42, and this tension pulls the guide member 42 toward the front side. Therefore, when the carrier tape CT is not tensioned, the guide member 42 hangs down under its own weight and is located in a position (referred to as the "first position") slightly forward of the position directly below the front spacer 52 ( FIG. 3 ).

[0043] When the tape feeder 22 pulls in the carrier tape CT unwound from the reel RL (upper reel RL1) held in the reel holder 41 as the current tape CTC to perform a component supply operation, the reel RL in the reel holder 41 that is unwound from the carrier tape CT to the tape feeder 22 rotates (rotates in place) within the reel holder 41 as the carrier tape CT is pulled by the tape feeder 22.

[0044] 7 is an explanatory diagram of the operation of the component mounting device 1 according to an embodiment of the present disclosure. Here, the direction in which the carrier tape CT pulls the reel RL (upper reel RL1) in the reel holder 41 is the direction in which the reel RL is guided by the guide member 42 positioned at the first position, that is, the direction facing downward rather than horizontally (arrow A shown in FIG. 7). This direction keeps the reel RL in the reel holder 41 and allows the reel RL to rotate stably within the reel holder 41.

[0045] Thus, in this embodiment, when the guide member 42 is in the first position where it presses down the carrier tape CT that has been unwound from the reel RL (upper reel RL1) in the suspended state, the guide member 42 guides the direction in which the reel RL is pulled by the carrier tape CT in a direction that is downward relative to the horizontal, i.e., in a direction that stops the reel RL within the reel holder 41. Therefore, even if the reel RL in the reel holder 41 receives a pulling force from the unwound carrier tape CT, it will not fall off (come out) from the reel holder 41, and will continue to rotate stably (rotate in place) within the reel holder 41.

[0046] 8 is an explanatory diagram of the operation of the component mounting device 1 according to an embodiment of the present disclosure. When the tape feeder 22 performs a component supply operation for the current tape CTC and the terminal end of the current tape CTC reaches the winding core MS of the upper reel RL1, the terminal end of the current tape CTC detaches from the winding core MS of the upper reel RL1. Then, the current tape CTC whose terminal end has detached from the winding core MS continues to be drawn into the tape feeder 22, and the upper reel RL1 remains in the reel holder 41 (FIG. 8).

[0047] FIG. 9 is an explanatory diagram of the operation of the component mounting device 1 according to an embodiment of the present disclosure. However, if for some reason the terminal end of the carrier tape CT cannot be released from the winding core MS, the tension in the carrier tape CT gradually increases, causing the guide member 42, which is holding the carrier tape CT, to be lifted by the tensed carrier tape CT. As a result, the pair of hanging members 62 supporting both ends of the guide member 42 rotate around the two spacers 52 (the spacers 52 on the front side of the arm member 61) to turn it upside down. Furthermore, the pair of arm members 61 are swung in the up-down direction via the pair of hanging members 62, and the guide member 42 abuts on the outer periphery of the reel RL from the center of rotation of the reel RL, from the front side ( FIG. 9 ). Hereinafter, the position of the guide member 42 abutting on the reel RL in this manner will be referred to as the "second position."

[0048] With the guide member 42 in the second position, the upper reel RL1 is subjected to a force from the tensed carrier tape CT in a direction in which it is pulled out from between the guide member 42 and the front spacer 52 (arrow B shown in FIG. 9). However, the guide member 42, which has been pulled up by the carrier tape CT, is in contact with the outer circumferential edge of the reel RL, so that the reel RL is prevented from falling off (coming out) from the reel holder 41.

[0049] In this embodiment, when the carrier tape CT pulled in by the tape feeder 22 is not tensioned, the guide member 42 is located at a position (first position) where it guides the carrier tape CT unwound from the reel RL so that it faces in a direction away from the tape feeder 22, but when the carrier tape CT is pulled by the tape feeder 22 and becomes tensioned, it is located (moves) at a position (second position) where it prevents the reel RL from being pulled out of the reel holder 41 by the tensioned carrier tape CT.

[0050] More specifically, when the carrier tape CT drawn in by the tape feeder 22 is not tensioned, the guide member 42 is located in a position (first position) where it pushes down the carrier tape CT being unwound from the reel RL in a hanging state hanging down under its own weight, thereby keeping the reel RL within the reel holder 41. However, when the carrier tape CT is drawn in by the tape feeder 22 and becomes tensioned, the guide member 42 is lifted up by the tensioned carrier tape CT and abuts against the reel RL in a state where the pair of hanging members 62 are inverted upside down, thereby being located (moving) to a position (second position) where it prevents the reel RL from being pulled out of the reel holder 41 by the tensioned carrier tape CT and falling off.

[0051] Thus, in the reel holding device (upper reel holding section 33) of this embodiment, the reel RL is kept in the reel holder 41 under normal circumstances when the carrier tape CT is not tensioned, and when the carrier tape CT is tensioned, the guide member 42 is lifted by the tensioned carrier tape CT to prevent the reel RL from falling off the reel holder 41. For this reason, the reel RL will not fall off the reel holder 41, not only when the carrier tape CT is not tensioned, but also when the carrier tape CT is tensioned.

[0052] As described above, when the guide member 42 prevents the reel RL from falling off the reel holder 41, the tension in the carrier tape CT increases further, causing the terminal end of the carrier tape CT to separate from the winding core MS of the reel RL. Once the terminal end of the carrier tape CT has separated from the winding core MS of the reel RL, the reel RL remains within the reel holder 41, the guide member 42 returns to a hanging state under its own weight, and the terminal end of the carrier tape CT is taken into the tape feeder 22. This results in a situation similar to that when the terminal end of the carrier tape CT has smoothly separated (FIG. 8).

[0053] 10 is an explanatory diagram of the operation of component mounting device 1 according to an embodiment of the present disclosure. When the current tape CTC runs out of components as a result of transporting the current tape CTC to its terminal end, tape feeder 22 moves the next tape CTN, which has been inserted in next-side insertion portion 22b as a replenishment tape and is being fed by lower reel RL2, to current-side insertion portion 22a (arrow C in FIG. 10), and then retracts the previous next tape CTN as a new current tape CTC, thereby continuing the component supply operation.

[0054] As described above, when the tape feeder 22 pulls in the carrier tape CT unwound from the lower reel RL2 and performs a component supply operation, the lower reel RL2 rotates (rotates in place) as it is pulled by the carrier tape CT (current tape CTC) pulled in by the tape feeder 22. The reel guide 80 of the lower reel holding unit 34 holds the lower reel RL2 so that the lower reel RL2 rotates without falling off the reel guide 80.

[0055] As described above, when the tape feeder 22 moves the next tape CTN that was inserted in the next-side insertion portion 22b to the current-side insertion portion 22a as the new current tape CTC, the next-side insertion portion 22b becomes empty. When the next-side insertion portion 22b becomes empty, the operator OP sets a replacement next tape CTN.

[0056] FIG. 11 is an explanatory diagram of the operation of the component mounting apparatus 1 according to an embodiment of the present disclosure. In the setting operation of the next tape CTN, first, the upper reel RL1, which has been used and is empty, is removed from the reel holder 41 of the upper reel holding section 33. In this case, the operator OP grasps the guide member 42, which is located in the first position, and moves it upward to a predetermined position (referred to as the "third position") higher than the second position (FIG. 11). Because this third position is higher than the second position, when the guide member 42 is located in the third position, the pair of hanging members 62 are in an upside-down position, and the pair of arm members 61 are raised in a direction in which the front portions thereof are lifted further than when the guide member 42 is located in the second position (FIG. 11).

[0057] In this embodiment, when the guide member 42 is positioned in the third position, the distance H (FIG. 11) between the guide member 42 and the spacer 52 on the front side of the reel holder 41 holding the reel RL is greater than the diameter of the reel RL. Therefore, by lifting the guide member 42 to the third position, the operator OP can pull out the empty upper reel RL1 toward the front and remove it from the reel holder 41 (arrow D shown in FIG. 11).

[0058] In this embodiment, when the guide member 42 is raised to the third position, each of the pair of arm members 61 abuts against the upper stopper 55 from below, preventing the pair of arm members 61 from being raised any further. In this embodiment, the guide member 42 is set to be in the third position when the guide member 42 is raised to a position where the pair of arm members 61 are in the maximum raised position (therefore, the guide member 42 is at the maximum position). Therefore, by raising the guide member 42 to a position where it is at the maximum height, the reel RL can be inserted into or removed from the reel insertion opening 41S of the reel holder 41 from below the guide member 42 (more specifically, between the guide member 42 and the spacer 52 on the front side of the reel holder 41).

[0059] In this embodiment, the guide member 42 can be positioned at a third position higher than the second position, and when the guide member 42 is positioned at the third position, the reel RL can be inserted into or removed from the reel insertion opening 41S from below the guide member 42.

[0060] The operator OP positions the guide member 42 in the third position and removes the used upper reel RL1 from the reel holder 41, and then, with the guide member 42 still in the third position, removes the lower reel RL2, which is located directly below the reel holder 41 from which the upper reel RL1 was removed, from the reel guide 80 and inserts it into the reel insertion opening 41S of the reel holder 41 (arrow E shown in FIG. 11). As a result, the previous lower reel RL2 becomes the new upper reel RL1.

[0061] FIG. 12 is an explanatory diagram of the operation of the component mounting device 1 according to an embodiment of the present disclosure. FIG. 13 is an explanatory diagram of the operation of the component mounting device 1 according to an embodiment of the present disclosure. After inserting the lower reel RL2 into the reel insertion slot 41S as described above, the operator OP pulls out the carrier tape CT from the newly prepared replenishment reel RL and inserts it into the tape loading section 22L of the tape feeder 22 (arrow F shown in FIG. 12). Then, by setting the new replenishment reel RL in the reel guide 80 of the vacant lower reel holding section 34, the replenishment reel RL becomes the new lower reel RL2 (arrow G shown in FIG. 12). This completes the replacement work of the reel RL due to a component shortage (FIGS. 13 and 7).

[0062] As described above, the guide member 42 has a length sufficient to cover the entire X-direction area of ​​the multiple reel holders 41 arranged side by side in the X-direction, and when none of the multiple reels RL held by the multiple reel holders 41 are in a tensioned state, the guide member 42 presses down all of the multiple carrier tapes CT by its own weight. When any of the multiple carrier tapes CT is in a tensioned state, the tensioned carrier tape CT lifts the guide member 42, preventing the tensioned carrier tape CT from pulling out (falling off) the reel RL (the upper reel RL1) from the reel holder 41. In this way, in this embodiment, one guide member 42 guides the carrier tape CT unwound from the multiple reels RL (the upper reel RL1) and prevents the reel RL from falling off the reel holder 41.

[0063] As described above, the reel holding device (upper reel holding section 33) provided in the component mounting device 1 in this embodiment is configured such that, when the carrier tape CT drawn in by the tape feeder 22 is not tensioned, the guide member 42 is located at a position (first position) where it guides the carrier tape CT unwound from the reel RL so as to face in a direction (a direction facing downward relative to the horizontal) that is not toward the tape feeder 22, but when the carrier tape CT is pulled by the tape feeder 22 and becomes tensioned, the guide member 42 is located at a position (second position) where it prevents the reel RL from being pulled out from the reel holder 41. Therefore, normally when the carrier tape CT is not tensioned, the reel RL is kept within the reel holder 41, and when the carrier tape CT is tensioned, the guide member 42 is lifted by the tensioned carrier tape CT to prevent the reel RL from falling off the reel holder 41. Therefore, the reel RL does not fall off the reel holder 41 not only when the carrier tape CT is not tensioned but also when the carrier tape CT is tensioned. Therefore, the reel holding device in this embodiment can prevent the reel RL from being pulled out from the reel holder 41 by the tensed carrier tape CT.

[0064] While the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above and various modifications are possible. For example, in the above-described embodiment, a plurality of reel holders 41 are arranged side by side in the direction in which the guide member 42 extends, and the pair of arm members 61 are positioned to sandwich the entire plurality of reel holders 41 from both sides. However, the number of reel holders 41 may not be multiple, and may be one. Furthermore, the pair of arm members 61 do not necessarily have to be positioned to sandwich the entire plurality of reel holders 41 from both sides, and may be positioned in the middle of the plurality of reel holders 41.

[0065] Furthermore, in the above-described embodiment, the pair of arm members 61 is located at both ends of the plurality of reel holders 41 and is composed of two reel holders 41 that are not used as reel holders 41, but instead of this configuration, the pair of arm members 61 may be composed of other members different from the reel holders 41.

[0066] Although various embodiments have been described above with reference to the accompanying drawings, the present disclosure is not limited to such examples. It is clear that those skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also fall within the technical scope of the present disclosure. Furthermore, the components of the various embodiments described above may be combined in any manner without departing from the spirit of the invention. [Industrial Applicability]
