First, referring to FIG. 1, the overall configuration of a tape feeder 1, which is a component supply device according to this embodiment, will be described. In FIG. 1, a tape feeder 1 has a function of supplying components to a component mounting apparatus (not shown).

The supply of components by the tape feeder 1 is carried out by a carrier having a plurality of pockets 20b (see FIGS. 6A and 6B) in which components P (see FIG. 3) are stored, and to which a cover tape 20a for sealing the pockets 20b is attached. This is done by transporting the tape 20 . The carrier tape 20 (see FIGS. 6A and 6B) has engagement pins (see engagement pins 7a shown in FIG. 3) that engage feed holes 20c (see FIGS. 6A and 6B) formed in the carrier tape 20. It is conveyed by rotating the provided sprocket.

The tape feeder 1 is constructed by arranging elements described below in a main body 2 made of a plate-like frame. These elements are covered by side covers 2f (see FIG. 3) provided on both sides. As shown in FIG. 1, the main body 2 has a tape transport path 4 (transport path) that communicates from a tape insertion opening 4a opened at the bottom on the upstream side to a supply position 4b set near the end of the upper surface on the upstream side. ) is provided. A carrier tape 20 containing components is introduced from the tape insertion port 4a into the tape conveying path 4, conveyed to the upper surface of the main body 2 through the oblique portion provided in the middle, and reaches the supply position 4b.

Then, at the supply position 4b, the component P is taken out from the main body 2 by moving the nozzle of the component mounting apparatus M up and down (arrow b) to perform the component picking operation. The picked component P is transferred to the component mounting apparatus by the mounting head (arrow c) and mounted on the substrate to be worked. Conveyance of the carrier tape 20 in the supply of the components is performed by the tape conveying section 3 (conveying section).

The tape conveying section 3 has a motor 5 , a conveying sprocket 6 , a positioning sprocket 7 and a discharge sprocket 8 . By driving the transport sprocket 6, the positioning sprocket 7 and the discharge sprocket 8 by the motor 5 as a driving source, the carrier tape 20 inserted from the tape insertion opening 4a is transported through the tape feeder 1 and positioned at the supply position 4b. be.

The cover tape 20a separated from the carrier tape 20 in the tape transport process is folded back upstream and collected into the cover tape storage portion 2b provided in the main body portion 2. As shown in FIG. The engagement of the carrier tape 20 with the positioning sprocket 7 and the ejection sprocket 8 is performed by pressing the carrier tape 20 against the positioning sprocket 7 and the ejection sprocket 8 with an opening/closing cover 18 (see FIGS. 2 and 3). .

A convex portion 2a for connection with a component mounting apparatus is provided on the bottom surface of the main body portion 2 on the upstream side. A connector 2c, an air joint 2d and a hook 2e are provided on the convex portion 2a. When the tape feeder 1 is set on the feeder base provided in the component supply section of the component mounting apparatus, the connector 2c and the air joint 2d are fitted and connected to the mating side (component mounting apparatus side). At this time, the tape feeder 1 is positionally fixed to the feeder base by the hook 2e. In this connected state, it is possible to supply power and air to the tape feeder 1 from the component mounting apparatus, and to exchange signals between the component mounting apparatus and the tape feeder 1 .

A feeder control unit 10 for controlling the operation of the tape feeder 1 is incorporated in the convex portion 2a. When the tape feeder 1 is connected to the component mounting apparatus, the feeder control section 10 is electrically connected to the device control section of the component mounting apparatus through the connector 2c. As a result, an operation command from the device control section of the component mounting apparatus is transmitted to the tape feeder 1, and an operation feedback signal for the component feeding operation by the tape feeder 1 is transmitted to the component mounting apparatus.

FIG. The conveying sprocket 6 is a third sprocket that engages with the feed holes 20c of the carrier tape 20 and rotates to convey the carrier tape 20 to the first sprocket.

Of these three sprockets, an opening/closing cover 18 (cover) is provided on the upper surface side of the positioning sprocket 7 and the ejection sprocket 8 so as to be able to open and close with respect to the main body portion 2 . The opening/closing cover 18 has a function of pressing the carrier tape 20 conveyed by the conveying sprocket gear 14 in the closed state. This pressing causes the engagement pins of the positioning sprocket 7 and the discharge sprocket 8 to engage with the feed holes 20c of the carrier tape 20 (see FIGS. 2 to 4A). That is, the tape conveying section 3 has an opening/closing cover 18 for pressing the carrier tape 20 against the positioning sprocket 7 as the first sprocket and the ejection sprocket 8 as the second sprocket. The opening/closing cover 18 covers the upper side of the carrier tape 20 conveyed by the tape conveying section 3 in the closed state.

A motor 5 generates torque to drive a positioning sprocket 7 as a first sprocket, a discharge sprocket 8 as a second sprocket, and a transfer sprocket 6 as a third sprocket. The tape conveying section 3 having the above-described structure has a plurality of gears for transmitting the torque generated by the motor 5 to the positioning sprocket 7 , the ejection sprocket 8 and the conveying sprocket 6 . These gears are a positioning sprocket gear 11 (first gear) coaxial with the positioning sprocket 7 which is the first sprocket, and a discharge sprocket gear 12 (second gear) coaxial with the discharge sprocket 8 which is the second sprocket. 2 gear), and a fourth transmission gear 13 (third gear) that meshes with the positioning sprocket gear 11 and the ejection sprocket gear 12 .

As shown in FIG. 3, an engagement pin 7a is provided on the outer circumference of the positioning sprocket 7. As shown in FIG. Feed holes 20c (see FIGS. 6A and 6B) are formed in the carrier tape 20 at a pitch corresponding to the pitch of the engaging pins 7a. By intermittently rotating the positioning sprocket 7 while engaging the engagement pins 7a with the feed holes, the carrier tape 20 is fed along the tape transport path 4 at a predetermined feed pitch. Similarly, the discharge sprocket 8 and the transfer sprocket 6 are intermittently rotated to feed the carrier tape 20 at a predetermined feed pitch.

The multiple gears of the tape transport section 3 include a transport sprocket gear 14 (fourth gear), a positioning sprocket gear 11 (first gear), and a third transmission gear 15 (fifth gear). Here, the carrier sprocket gear 14 (fourth gear) is coaxial with the carrier sprocket 6, which is the third sprocket. The third transmission gear 15 (fifth gear) meshes with the conveying sprocket gear 14 (fourth gear).

Furthermore, the multiple gears described above further include a peeling roller gear 16 (sixth gear) and a fifth transmission gear 17 (seventh gear). Here, the peeling roller gear 16 (sixth gear) is coaxial with the driving peeling roller 22 (see FIG. 4A) of the tape peeling mechanism 21 that feeds and picks up the cover tape 20a peeled from the carrier tape 20 . A fifth transmission gear 17 (seventh gear) meshes with the separation roller gear 16 and the conveying sprocket gear 14 . In this embodiment, the tape conveying section 3 in which a plurality of gears are arranged rotates the conveying sprocket 6, the positioning sprocket 7, and the ejection sprocket 8 using a single motor 5 as a driving source. .

As a result, the carrier tape 20 introduced from the tape insertion port 4a is conveyed to the positioning sprocket 7 by the conveying sprocket 6. As shown in FIG. Then, the positioning sprocket 7 positions the carrier tape 20 at the supply position 4b. Furthermore, the carrier tape 20 from which the components P have been taken out at the supply position 4b is discharged to the downstream side of the tape feeder 1 by the discharge sprocket 8. As shown in FIG. With such a configuration, the carrier tape 20 can be stably and reliably conveyed in the tape feeder 1 .

In this embodiment, the diameter of the ejection sprocket 8, which is the second sprocket, is smaller than the diameter of the positioning sprocket 7, which is the first sprocket. As a result, the side of the tape feeder 1 that is close to the component mounting apparatus can be made compact, and the component supply section to which the plurality of tape feeders 1 are mounted can be miniaturized in the component mounting apparatus.

Next, referring to FIGS. 4A, 4B, and 5, the configuration of an opening/closing cover 18 that covers the upper surfaces of the positioning sprocket 7 and the ejection sprocket 8 and presses the carrier tape 20 against the positioning sprocket 7 and the ejection sprocket 8 for engagement. and functions.

A first escape portion 18d and a second escape portion 18e are provided to escape the pin 8a. Further, the cover portion 18a is provided with a notch portion 18c formed by notching the first relief portion 18d to one side surface. As shown in FIG. 4B, the opening/closing cover 18 is provided with a base portion 18f with both side surfaces extending upstream. Further, the opening/closing cover 18 is provided with an engaging portion 18g (see FIG. 5) formed by extending the cover portion 18a toward the downstream side.

In FIG. 5, a block 31 is a rectangular block-shaped member and fixed to the main body 2 . A substantially plate-shaped tape pressing member 30 is arranged along the tape transport path 4 between the lower surface side of the block 31 and the upper surface of the tape transport path 4 . The tape pressing member 30 has a function of contacting the upper surface of the carrier tape 20 conveyed along the tape conveying path 4 and pressing it from above (see FIGS. 6A and 6B).

The tape pressing member 30 is urged downward by a spring member 33 arranged between it and the block 31 so that it can be displaced in the thickness direction of the carrier tape 20 . As a result, a plurality of types of carrier tapes 20 having different thicknesses can be stably conveyed without forming gaps on the pressing surface.

The opening/closing cover holding portion 19 is rotatably supported on the block 31 via a support shaft 32 . The opening/closing cover holding portion 19 is a substantially disk-shaped member having an extension portion 19c partially extending in the tangential direction. A base portion 18f of the opening/closing cover 18 shown in FIG. 4B is fixed to the extending portion 19c by screwing. With such a configuration, the opening/closing cover 18 is held by the opening/closing cover holding portion 19 with respect to the main body portion 2 of the tape feeder 1 so as to be openable and closable. That is, the opening/closing cover holding portion 19 has a function of holding the opening/closing cover 18 and opening/closing the opening/closing cover 18 with respect to the body portion 2 of the tape feeder 1 .

FIG. 5 shows a state in which the opening/closing cover 18 held by the opening/closing cover holding portion 19 is closed. In this state, the opening/closing cover 18 is kept closed by the lock mechanism provided on the front cover 9 . That is, the front cover 9 includes an elevating portion 9a that can slide vertically with respect to the base portion 9b (arrow d) and that is biased downward by a biasing spring member 9c. The sliding motion of the elevating section 9a is guided by a guide mechanism combining a long hole 9e provided in the elevating section 9a and a pin 9d provided in the base 9b.

A locking pin 9f (see FIG. 4A) is provided on the upper portion of the lifting portion 9a, and the locking pin 9f has a shape capable of locking the locking portion 18g extending from the downstream end of the opening/closing cover 18. It has become. In order to close the opening/closing cover 18, the lifting portion 9a is first lifted to raise the locking pin 9f, and in this state the opening/closing cover 18 is closed to position the locking portion 18g below the locking pin 9f. Next, in this state, the lifting portion 9a is lowered to bring the locking pin 9f into contact with the locking portion 18g. As a result, the engaging portion 18g is pressed downward by the biasing force of the biasing spring member 9c and locked, and the open/close cover 18 is kept closed.

To open the opening/closing cover 18 from the closed state, the opening operation shown in FIG. 9 is performed. That is, first, the elevating portion 9a is raised against the biasing force of the biasing spring member 9c to release the locked state in which the locking portion 18g is held down by the locking pin 9f. Next, the opening/closing cover 18 is lifted to the open state shown in FIG. 9 (arrow m).

The opening/closing cover holding portion 19 in the present embodiment is provided with a positioning member 40 configured as described below for positioning the opening/closing cover holding portion 19 in the open state and the closed state in the opening/closing operation described above ( See Figure 12). As shown in FIG. 12, on the outer periphery of the opening/closing cover holding portion 19, two concave portions, a first engaging portion 19a and a second engaging portion 19b corresponding to the open/closed state of the opening/closing cover 18, are formed. .

Further, a positioning member 40 having a positioning projection 40a engageable with the first engaging portion 19a and the second engaging portion 19b is arranged on the outer periphery of the opening/closing cover holding portion 19. As shown in FIG. The positioning member 40 is rotatable around a fulcrum 40b, and is moved in the direction of arrow q, i.e., the positioning projection 40a to the first engaging portion 19a by a biasing spring member 41 coupled to the opposite end of the positioning projection 40a. , is urged in the direction of engaging with the second engaging portion 19b. As a result, the opening/closing cover 18 is positioned as described below.

First, when opening the opening/closing cover 18, as shown in FIG. 13, by lifting the opening/closing cover 18 (arrow r), the opening/closing cover holding portion 19 is rotated to move the positioning convex portion 40a to the first engagement. Engage with joint 19a. When the opening/closing cover 18 is to be closed, the positioning convex portion 40a is engaged with the second engaging portion 19b as shown in FIG.

As a result, the opening/closing cover holding portion 19 can be positioned according to the opening/closing state of the opening/closing cover 18 . That is, in the present embodiment, the opening/closing cover holding portion 19 has a first engaging portion 19a that engages with the positioning convex portion 40a when the opening/closing cover 18 is open, and positions the opening/closing cover 18 when the opening/closing cover 18 is closed. It is configured to have a second engaging portion 19b that engages with the convex portion 40a.

12, in order to stabilize the engaging state of the carrier tape 20 with the positioning sprocket 7 and the ejection sprocket 8 that constitute the tape conveying section 3, the opening and closing cover 18 is attached to the tape conveying section 3. It is desirable that an urging force F pressing against is acting. In order to achieve this biasing force F with a simple structure, the extending portion 19c connecting the opening/closing cover 18 to the opening/closing cover holding portion 19 may be provided with a biasing means 19d having a function of applying the above-described biasing force F. desirable. As the biasing means 19d, for example, an elastic member such as a coiled spring that generates elastic force in the rotational direction can be used.

Next, with reference to FIGS. 4A, 4B, and 5, the configuration and function of the tape peeling mechanism 21 for picking up the cover tape 20a peeled from the carrier tape 20 will be described. As shown in FIG. 5 , a tape peeling mechanism 21 is arranged in the tape conveying path 4 on the upstream side of the positioning sprocket 7 . The tape peeling mechanism 21 includes a driving peeling roller 22 and a driven peeling roller 23, which are a pair of rollers for picking up the cover tape 20a peeled from the carrier tape 20. As shown in FIG.

The drive peeling roller 22 and the driven peeling roller 23 are toothed rollers provided with mutually meshing teeth on their outer circumferences. It has a function to pick up As shown in FIG. 5 , one of the pair of rollers, the driving peeling roller 22 , is attached to the opening/closing cover holding portion 19 . The driven peeling roller 23, which is one of the pair of rollers, is rotatably provided at the downstream end of the tape pressing member 30 arranged along the tape transport path 4 on the lower surface side of the block 31. As shown in FIG. With this configuration, the distance between the pair of driving peeling roller 22 and driven peeling roller 23 changes in conjunction with the opening and closing of the opening/closing cover 18 by rotating the opening/closing cover holding portion 19 .

A tape cover 24 is provided downstream of the tape pressing member 30 in the tape transport path 4 along the upper surface of the tape transport path 4 up to a position before the supply position 4b. The tape cover 24 is fixed to the tape pressing member 30 and can be displaced along with the tape pressing member 30 in the thickness direction of the carrier tape 20 . The tape cover 24 functions as a first cover that covers the upper surface of the carrier tape 20 from which the cover tape 20 a has been peeled by the tape peeling mechanism 21 .

That is, in the carrier tape 20 with the cover tape 20a peeled off, the pocket 20b is exposed and the stored component P becomes unstable. By covering the upper surface of the carrier tape 20 with the tape cover 24, the carrier tape 20 after the cover tape 20a is peeled off can be stably conveyed without causing problems such as falling off of the parts P.

It is also possible to make the downstream end of the tape cover 24 function as a peeling section 24a for peeling the cover tape 20a from the carrier tape 20 (see FIGS. 10 and 11). In this case, the tape cover 24 is a first cover provided with a peeling portion 24a for holding down the carrier tape 20 and peeling off the cover tape 20a.

In the tape feeder 1 according to the present embodiment, the tape cover 24, which is the first cover, is fixed to the tape pressing member 30 that presses the carrier tape 20 upstream of the pair of the driving stripping roller 22 and the driven stripping roller 23. are provided. The opening/closing cover 18, which is the second cover, is provided with a component take-out opening 18b as a supply unit for supplying the component P to the component mounting apparatus, and is configured to be openable and closable with respect to the main body of the tape feeder 1. It's becoming

Next, the driving mechanism of the tape peeling mechanism 21 will be described. As shown in FIG. 4A, the driving stripping roller 22 is provided coaxially with the stripping roller gear 16 . A fifth transmission gear 17 that meshes with the peeling roller gear 16 is provided coaxially with the opening/closing cover holding portion 19 . In the opening/closing cover holding portion 19, the drive peeling roller 22 is arranged at a position where the coaxial peeling roller gear 16 meshes with the fifth transmission gear 17 (see also FIG. 2).

Therefore, when the opening/closing cover holding portion 19 rotates with the opening/closing of the opening/closing cover 18, the peeling roller gear 16 is always engaged with the fifth transmission gear 17. It rolls along the outer circumference of 17 . In this rolling, the rotation is transmitted from the fifth transmission gear 17 to the peeling roller gear 16 regardless of the position of the peeling roller gear 16, and the drive peeling roller 22 is rotationally driven.

That is, the above configuration has a peeling roller gear 16 (roller gear) and a fifth transmission gear 17 (roller driving gear). Here, the stripping roller gear 16 (roller gear) is coaxial with the driving stripping roller 22 . The fifth transmission gear 17 (roller driving gear) rotates the driving peeling roller 22 by driving the peeling roller gear 16 . By rotating the opening/closing cover holding portion 19 coaxially with the fifth transmission gear 17 , the opening/closing cover 18 opens and closes, and the peeling roller gear 16 rolls on the outer circumference of the fifth transmission gear 17 .

As shown in FIG. 5, the driven peeling roller 22 that is rotationally driven in this way meshes with the driven peeling roller 23 only when the opening/closing cover 18 is closed. The tape peeling mechanism 21 in this embodiment is configured to perform the function of pinching the cover tape 20a between the driving peeling roller 22 and the driven peeling roller 23 only when the opening/closing cover 18 is closed. That is, when the opening/closing cover 18 is closed to cover the upper side of the carrier tape 20, the cover tape 20a is sandwiched and captured by the pair of the driving peeling roller 22 and the driven peeling roller 23. As shown in FIG. When the opening/closing cover 18 is opened, the gap between the pair of drive peeling roller 22 and driven peeling roller 23 is widened to release the cover tape 20a.

Next, with reference to FIGS. 6A, 6B, and 7, the detailed configuration of the driven peeling roller 23 constituting the tape peeling mechanism 21 and the guide mechanism for guiding the carrier tape 20 conveyed to the tape peeling mechanism 21 will be described. . 6A shows a cross section of the downstream end of the tape holding member 30 in a direction orthogonal to the transport direction of the carrier tape 20. FIG. In FIG. 6A, the upper surface of the main body 2 is a tape transport surface 2i for transporting the carrier tape 20. As shown in FIG. The tape conveying path 4 is open to the tape conveying surface 2i, and the carrier tape 20 is set in the tape conveying path 4 with the pocket 20b positioned in the conveying state. In this set state, the carrier tape 20 is in contact with the tape transport surface 2i, and the convex portion 30a provided on the lower surface of the tape pressing member 30 is in contact with the upper surface of the cover tape 20a.

As shown in FIG. 6B, a spring member 33, which is an elastic body, is attached to a concave portion 30b formed on the upper surface of the tape pressing member 30 and a concave portion 31a formed on the lower surface of the block 31. As shown in FIG. The spring member 33 is a compression spring, and exerts an urging force in the pressing direction between the fixed block 31 and the tape pressing member 30 that can be displaced in the thickness direction. As a result, the convex portion 30a formed on the lower surface of the tape pressing member 30 comes into contact with the cover tape 20a and presses the carrier tape 20 against the tape conveying surface 2i (arrow e).

In the above configuration, the tape pressing member 30 is connected to a block 31 fixed to the body portion 2 of the tape feeder 1 by a spring member 33 as an elastic body. This makes it possible to absorb the difference in thickness of the carrier tape 20 to be conveyed. Further, the tape holding member 30 has a convex portion 30a that can come into contact with the cover tape 20a on the upper surface of the carrier tape 20. As shown in FIG. As a result, in the structure in which the carrier tape 20 is pressed by the tape pressing member 30, it is possible to prevent the problem that the tape pressing member 30 sticks to the cover tape 20a and interferes with the smooth sliding operation.

6A, a peeling roller support shaft 36 is rotatably held via a bearing 35 in a bearing portion 34 provided at one side end portion of the tape pressing member 30. As shown in FIG. A roller member 37 constituting the driven peeling roller 23 is coupled to the peeling roller support shaft 36 . The roller member 37 is a toothed roller member provided with teeth engaging with the driving peeling roller 22 on its outer periphery, and two circumferential grooves 37a are formed on its outer periphery.

A entanglement prevention member 38 shown in FIG. 7 engages with the circumferential groove 37a in a form that allows the rotation of the roller member 37 around the peeling roller support shaft 36. As shown in FIG. The entanglement prevention member 38 is a plate member that engages with the inner periphery of the circumferential groove 37a in the form of an E-ring, and its upstream end is fixed to the block 31 (see FIG. 7).

That is, the roller member 37 is supported around the peeling roller support shaft 36 and held in a state where it is allowed to rotate by the entanglement prevention member 38 . It should be noted that illustration of the entanglement prevention member 38 is omitted in FIG. 4A. Further, the driving separation roller 22 is also equipped with a entanglement prevention member 38 having a similar structure. The presence of the entanglement prevention member 38 in the form of being fitted in the circumferential groove 37a formed in the roller member 37 provides the following effects.

In tape peeling, in which the cover tape 20a is sandwiched between a pair of driving peeling rollers 22 and driven peeling rollers 23 and pulled off, the sandwiched cover tape 20a winds around one of the peeling rollers, preventing normal tape pulling. may occur. By providing the entanglement preventing member 38 as shown in the present embodiment, the cover tape 20a is prevented from being entangled in the outer periphery of the driving peeling roller 22 and the driven peeling roller 23. FIG.

That is, the entanglement prevention member 38 functions as an entanglement prevention portion that prevents the cover tape 20a picked up by the pair of driving peeling roller 22 and driven peeling roller 23 from being entangled. The driven peeling roller 23, which is one of the pair of the driving peeling roller 22 and the driven peeling roller 23, is attached to the block 31 fixed to the main body 2 of the tape feeder 1 via the entanglement prevention member 38 as an entanglement prevention portion. It has a connected form.

In the above-described configuration, the driven peeling roller 23 of the tape peeling mechanism 21 is held by the tape pressing member 30 via the peeling roller support shaft 36 . As a result, even if the thickness of the target carrier tape 20 changes, the driven peeling roller 23 moves along with the tape pressing member 30 in the thickness direction of the carrier tape 20, and the distance of the driven peeling roller 23 from the cover tape 20a remains constant. kept in

In FIG. 6A, the bottom surface of the tape transport path 4 has air ejection holes 2h at positions corresponding to the tape peeling mechanism 21 comprising a pair of rollers (see FIG. 7). The air ejection holes 2 h eject air supplied through the air joint 2 d (see FIG. 1) and the air supply holes 2 g between the driven separation roller 22 and the driven separation roller 23 . As a result, the leading edge of the cover tape 20 a peeled from the carrier tape 20 is blown up and introduced between the driving peeling roller 22 and the driven peeling roller 23 .

That is, the air joint 2d, the air supply hole 2g, and the air ejection hole 2h for supplying air correspond to a driving peeling roller 22 and a driven peeling roller 23, which are a pair of rollers, in the tape transport path 4 of the carrier tape 20. placed in position. The air joint 2d, the air supply hole 2g, and the air jetting hole 2h are introduction portions for introducing the cover tape 20a between the driving peeling roller 22 and the driven peeling roller 23 by using the flow of gas jetted from the air jetting hole 2h. constitutes At this time, as described above, since the distance from the cover tape 20a to the driven peeling roller 23 is kept constant, the leading edge of the cover tape 20a blown up can be reliably captured by the driving peeling roller 22 and the driven peeling roller 23. .

In the example shown in this embodiment, the air jetted from the air jetting holes 2h is used as the gas flow described above. Instead of blowing air, a negative pressure is applied between the driving peeling roller 22 and the driven peeling roller 23, and this negative pressure is used to move the cover tape 20a between the driving peeling roller 22 and the driven peeling roller 23. may be introduced into

Figures 8A-8C show the take-up operation of the cover tape 20a by the lead-in section described above. This take-up operation is automatic peeling performed with the opening/closing cover 18 closed. First, as shown in FIG. 8A, the carrier tape 20 is conveyed along the tape conveying path 4 in a state in which a predetermined length of the cover tape 20a has been peeled off from the carrier tape 20 in advance (arrow g). At this time, in the tape peeling mechanism 21, the driving peeling roller 22 is rotationally driven, so that the pair of driving peeling roller 22 and driven peeling roller 23 are both in a rotating state (arrows i and j). Introductory air is ejected from an air ejection hole 2h provided in the tape transport path 4 (arrow h).

When the transport is continued in this state, the peeled cover tape 20a at the leading end reaches the tape peeling mechanism 21 as shown in FIG. 8B. The cover tape 20a at the leading end is blown up by the action of air ejected from the air ejection holes 2h and introduced between the driving peeling roller 22 and the driven peeling roller 23. As shown in FIG. Then, the cover tape 20a is sandwiched between the rotating drive peeling roller 22 and the driven peeling roller 23, so that the cover tape 20a is peeled off from the carrier tape 20 and taken up, as shown in FIG. 8C.

FIG. 9 shows a state in which the opening/closing cover 18 is opened after the automatic peeling described above. First, the elevating portion 9a of the front cover 9 is lifted (arrow k) to release the locking of the locking portion 18g by the locking pin 9f. Next, the opening/closing cover 18 is lifted (arrow m), the opening/closing cover holding portion 19 is rotated around the support shaft 32, and as shown in FIG. . As a result, the opening/closing cover 18 is kept open with respect to the main body 2 .

Next, with reference to FIGS. 10 and 11, an embodiment in which the cover tape 20a is peeled off using the peeling portion 24a of the tape cover 24 without using the automatic peeling by the tape peeling mechanism 21 will be described. As in this embodiment, when a plurality of types of carrier tapes 20 are to be worked, the peeling characteristics of the cover tape 20a differ depending on the carrier tapes 20 to be worked. That is, there are not only the types of tapes shown in FIGS. 8A to 8C to which automatic peeling can be applied without problems, but also the types of tapes for which it is difficult to perform automatic peeling without operational errors.

Therefore, in the present embodiment, for tape types for which automatic peeling is difficult to apply, the cover tape 20a is peeled using the peeling portion 24a of the tape cover 24, as described below. In this mode, first, as shown in FIG. 10, the opening/closing cover 18 is opened (arrow n). In this state, the carrier tape 20 is fed along the tape transport path 4, passes under the tape cover 24, and reaches the front cover 9 via the top of the positioning sprocket 7 and the discharge sprocket 8. Let Thereby, the cover tape 20a is exposed on the downstream side of the tape cover 24 .

Next, the exposed cover tape 20a is peeled off from the carrier tape 20 and, as shown in FIG. The peeled cover tape 20a is guided to the cover tape storage section 2b on the upstream side through between the opening/closing cover 18 and the tape cover 24 (arrow o).

Next, as shown in FIG. 11, the opening/closing cover 18 is closed and locked by the front cover 9 . That is, a downward biasing force is applied to the biasing spring member 9c of the elevating portion 9a of the front cover 9 (arrow p), and the locking portion 18g of the opening/closing cover 18 is pressed downward by the locking pin 9f. In this state, the driving peeling roller 22 attached to the opening/closing cover holding portion 19 is positioned to mesh with the driven peeling roller 23 . As a result, the cover tape 20a is nipped between the pair of the driving peeling roller 22 and the driven peeling roller 23 and pulled upstream.

That is, in the peeling mode using the peeling portion 24a of the tape cover 24, the cover tape 20a is folded back in the direction opposite to the conveying direction of the carrier tape 20 at the peeling portion 24a of the tape cover 24, which is the first cover. stripped by Then, the cover tape 20a peeled off by the peeling portion 24a is picked up by a pair of drive peeling roller 22 and driven peeling roller 23 through between the tape cover 24 which is the first cover and the opening/closing cover 18 which is the second cover. .

In other words, the tape feeder 1 according to the present embodiment has the first stripping path for performing the above-described automatic stripping and the second stripping path for stripping the cover tape 20a using the stripping portion 24a of the tape cover 24. It has a configuration with a peeling path of .

In other words, the first peeling path has a tape conveying path 4 along which the carrier tape 20 is conveyed, and a pair of driving peeling roller 22 and driven peeling roller 23 . Here, the pair of drive peeling roller 22 and driven peeling roller 23 pinches the cover tape 20a at the tip of the carrier tape 20 and peels off the cover tape 20a from the carrier tape 20 .

The second peeling path includes a tape conveying path 4 along which the carrier tape 20 is conveyed, a tape cover 24 (cover), and the cover tape 20a peeled at the peeling section 24a. and a path leading to 23. The tape cover 24 presses the carrier tape 20 and has a peeling portion 24a for peeling the cover tape 20a from the carrier tape 20 at the end of the carrier tape 20 in the transport direction.

Next, with reference to FIGS. 14, 15A to 15C, and 16, the backlash adjusting function of the tape conveying section 3 of the tape feeder 1 according to the present embodiment will be described. In the tape feeder 1, in order to ensure high accuracy of the parts stop position at the supply position 4b, it is required to transmit the torque generated by the motor 5, which is the drive source, to the positioning sprocket 7 with high accuracy. For this reason, the tape transport section 3 shown in the present embodiment employs the following configuration so that the backlash can be adjusted with high precision and good workability at the key points of torque transmission.

FIG. 14 shows a transmission path for transmitting the torque generated by the motor 5 in the tape conveying section 3 to the positioning sprocket 7. As shown in FIG. In this transmission path, since the motor 5 and the drive gear 50, the first transmission gear 51 and the second transmission gear 52, and the positioning sprocket 7 and the positioning sprocket gear 11 are coaxial, rotation transmission error may occur. A certain point is limited to a transmission point from the drive gear 50 to the first transmission gear 51 and a transmission point from the second transmission gear 52 to the positioning sprocket gear 11 via the third transmission gear 15 .

For this reason, in the present embodiment, at least one gear to be adjusted is rotatably supported so that the backlash at the two transmission points can be adjusted with high accuracy and good workability. A support member that can be displaced with respect to the portion 2 is provided.

First, at least one gear includes a drive gear 50 provided coaxially with the motor 5 . The motor mounting member 5a supports the motor 5 and the driving gear 50, and by finely adjusting the position of the motor mounting member 5a, the relative position between the driving gear 50 and the first transmission gear 51 can be finely adjusted ( Arrow s), adjust the backlash. Here, the motor mounting member 5a is connected to the main body portion 2 of the tape feeder 1 through a support shaft 5b, and the motor mounting member 5a can be displaced by rotating around the support shaft 5b.

At least one gear includes a third transmission gear 15 meshing with the positioning sprocket gear 11 and the second transmission gear 52 . A slide member 15a supporting the third transmission gear 15 is fitted in a guide groove 43 (see also FIG. 2) formed in the body portion 2 of the tape feeder 1. As shown in FIG. That is, the slide member 15a is guided by the guide surface 43a of the guide groove 43 with respect to the main body 2 of the tape feeder 1 in the predetermined direction indicated by the arrow t. Here, the predetermined direction indicated by the arrow t is a direction in which the relative positions of the third transmission gear 15, the positioning sprocket gear 11, and the second transmission gear 52 can be finely adjusted together. Displacement to slide to is possible.

The motor mounting member 5a and the slide member 15a are adjusted by a position adjustment tool 44 shown in FIGS. installed as possible. That is, a position adjustment tool 44 described below is fitted into the adjustment openings 42 provided in the motor attachment member 5a and the slide member 15a, respectively, and a predetermined adjustment operation is performed, whereby the motor attachment member 5a and the slide member 15a are adjusted. A fine adjustment of the position of the member 15a is performed. After the fine adjustment is executed, the motor mounting member 5a and the slide member 15a are fixed to the main body 2 by tightening the fixing screws 5c and 15d, respectively.

Figures 15A-15B show the configuration and adjustment operation of the alignment tool 44 used for this fine adjustment. As shown in FIG. 15A, the position adjustment tool 44 has a configuration in which a cylindrical rod-shaped operating member 45 is coupled to a circular member 46, and a projecting portion 45a is formed by protruding the tip of the operating member 45 from the circular member 46. As shown in FIG. ing.

The position adjusting tool 44 is an eccentric tool, and as shown in FIG. 15B, the axis of the operating member 45 is eccentrically provided with respect to the center of the circular member 46 by a predetermined eccentric amount e. Fitting portions 2j for fitting projections 45a are provided in the body portion 2 at positions corresponding to the adjustment openings 42 formed in the motor mounting member 5a and the slide member 15a.

In order to finely adjust the positions of the motor mounting member 5a and the slide member 15a with the position adjustment tool 44, as shown in FIG. Together with fitting, the projecting portion 45a is fitted to the fitting portion 2j. In this state, the operating member 45 is rotated (arrow u) to rotate the circular member 46 around the operating member 45 . At this time, by adjusting the rotation direction and rotation amount of the operation member 45, the motor mounting member 5a and the slide member 15a can be displaced by a desired adjustment amount (arrow v).

For this position adjustment, as shown in FIG. 16, first, the fixing screws 5c and 15d are loosened to make the motor mounting member 5a and the slide member 15a displaceable, and then the working operation shown in FIG. 15C is performed. That is, the position adjustment tool 44 is sequentially inserted into the adjustment openings 42 of the motor mounting member 5a and the slide member 15a, and the operation shown in FIG. )I do.

By this operation, the motor mounting member 5a is displaced around the support shaft 5b so that the drive gear 50 moves in the direction of the arrow s. Similarly, the slide member 15a is displaced so that the third transmission gear 15 slides in the arrow t direction. This displacement adjusts the backlash of the meshing portions of the driving gear 50 and the first transmission gear 51 , the third transmission gear 15 and the positioning sprocket gear 11 and the second transmission gear 52 . After adjusting the backlash in this manner, the fixing screws 5c and 15d are tightened to fix the positions of the motor mounting member 5a and the slide member 15a.

As described above, the tape feeder 1 shown in the present embodiment conveys the carrier tape 20 having a plurality of pockets 20b in which components are stored and to which the cover tape 20a for sealing the pockets 20b is attached. Supplies components to component mounters. The tape feeder 1 includes a tape conveying portion 3 that engages with the carrier tape 20 to convey the carrier tape 20, an openable and closable cover 18 that covers the upper side of the carrier tape 20 conveyed by the tape conveying portion 3, and a carrier tape. A pair of driving peeling rollers 22 and driven peeling rollers 23 are provided for picking up the cover tape 20a peeled from the tape 20a. The distance between the pair of driving peeling roller 22 and driven peeling roller 23 changes in conjunction with the opening and closing of the opening/closing cover 18 . With this configuration, the opening and closing of the opening and closing cover 18 and the opening and closing of the pair of driving peeling roller 22 and driven peeling roller 23 can be performed simultaneously in a single operation, thereby simplifying the preparation work for setting the carrier tape 20. can improve efficiency.

A modified example of the tape feeder 1 shown in the present embodiment is a tape feeder 1 having the same configuration as described above, in which a pair of driven peeling rollers separates the cover tape 20a from the carrier tape 20 by pinching and pulling the cover tape 20a. 22, a driven peeling roller 23, and a tape cover 24 provided with a peeling portion 24a for holding down the carrier tape 20 and peeling off the cover tape 20a. As a result, the configuration is such that two types of peeling methods can be selectively executed. With this configuration, even when a plurality of types of carrier tapes 20 with different characteristics are targeted, the cover tape 20a can be reliably peeled from the carrier tape 20 by a peeling method according to the characteristics of the carrier tape 20, preventing mounting errors. can suppress the occurrence of

Another modified example of the tape feeder 1 shown in the present embodiment is the tape feeder 1 having the same configuration as described above. A positioning sprocket 7 for conveying the parts to the supply position 4b and a discharge sprocket 8 for discharging the carrier tape 20 from the tape feeder 1 by engaging with the feed holes 20c of the carrier tape 20 after the parts have been supplied and rotating. Prepare. The diameter of the discharge sprocket 8 is set smaller than the diameter of the positioning sprocket 7 . As a result, in the tape feeder 1 having the discharge sprocket 8, the size of the leading end portion can be reduced to achieve compactness.

Another modified example of the tape feeder 1 shown in the present embodiment is a tape feeder 1 having the same configuration as described above, in which a pair of tape feeders are provided on the tape transport path 4 for transporting the carrier tape 20 and pull the cover tape 20a therebetween. , a driven peeling roller 22 , a driven peeling roller 23 , and a tape pressing member 30 that presses the upper surface of the carrier tape 20 and is displaceable in the thickness direction of the carrier tape 20 . The driven peeling roller 23, which is one of the pair of rollers, is rotatably provided on the tape pressing member 30. As shown in FIG. As a result, in the structure in which the cover tape 20a is taken off by a pair of rollers, the cover tape 20a can be taken off stably even when the carrier tape 20 is thin.

Another modified example of the tape feeder 1 shown in the present embodiment is the tape feeder 1 having the same configuration as described above, in which the carrier tape 20 is engaged with the feeding holes 20c provided in the carrier tape 20 to rotate and feed to the component mounting apparatus. It comprises a positioning sprocket 7 for carrying parts to a position, a motor 5 for generating torque for rotating the positioning sprocket 7 and at least one gear for transmitting the torque to the positioning sprocket 7 . It has a motor mounting member 5a and a slide member 15a that rotatably support at least one gear and that can be displaced with respect to the main body 2 of the tape feeder 1. As shown in FIG. As a result, it is possible to easily adjust the backlash, and to ensure high component stop position accuracy.

Next, with reference to FIGS. 17A and 17B, another modification of the component supply device of this embodiment will be described. The tape feeder 1 shown in FIGS. 1 to 16 is configured such that the opening/closing cover 18 is opened by lifting the downstream side during the opening/closing operation of the opening/closing cover 18 . In contrast, in the modified embodiment shown in FIGS. 17A and 17B, the opening/closing cover 118 is opened by lifting the upstream side.

In FIG. 17A, a tape feeder 101 has a function of conveying a carrier tape 20 and supplying components to a component mounting apparatus, like the tape feeder 1 shown in FIG. The tape feeder 101 has a tape transport section 103 having the same configuration and function as the tape transport section 3 in the tape feeder 1 . Similar to the tape feeder 1 , the tape transport section 103 includes a positioning sprocket 107 and a discharge sprocket 108 that engage with the carrier tape 20 supplied from the upstream side along the tape pressing member 130 in the tape transport path 4 . . By rotating the positioning sprocket 107 and the discharge sprocket 108 by a drive motor (not shown), the tape transport section 103 transports the carrier tape 20 downstream and positions it at a predetermined component supply position.

The upper side of the carrier tape 20 conveyed by the tape conveying section 103 is covered with an opening/closing cover 118 that can be opened and closed. The opening/closing cover 118 has a cross-sectional shape similar to that of the opening/closing cover 18 in the tape feeder 1, and the upper surface thereof is a cover portion 118a that abuts and presses the carrier tape 20. As shown in FIG. By pressing the upper surface of the carrier tape 20 with the opening/closing cover 118 , the carrier tape 20 engages with the positioning sprocket 107 and the ejection sprocket 108 .

The opening/closing operation of the opening/closing cover 118 and the cover mounting portion for pressing and mounting the opening/closing cover 118 against the main body portion 102 will be described. A downstream mounting portion 109 and an upstream mounting portion 110 having the following configurations are provided at positions corresponding to the downstream and upstream ends of the opening/closing cover 118 in the body portion 102 .

The downstream mounting portion 109 will be described below. A holding member 60 having a substantially gate-shaped cross section is fixed to the downstream end of the main body 102 . When the opening/closing cover 118 is attached, the side surfaces of the holding member 60 (the paper surface in FIG. 17A) are sandwiched by the side surfaces of the opening/closing cover 118 from both sides in the horizontal direction. A side surface of the holding member 60 is formed with an elongated hole 60a extending in the vertical direction. Cover mounting pins 118b are fixed to the downstream end of the opening/closing cover 118 and extend horizontally through the cover mounting pins 118b. With the opening/closing cover 118 attached, the cover attachment pin 118b is fitted into the elongated hole 60a while allowing vertical movement.

A compression spring member 61 is mounted inside the holding member 60 to bias the cover mounting pin 118b downward. As a result, the cover mounting pin 118b is pressed against the lower end in the long hole 60a and held in this position. That is, the opening/closing cover 118 is held by the main body portion 102 by the downstream mounting portion 109, and a downward pressing force acts on the tip portion of the opening/closing cover 118 (arrow z1). A torsion spring may be used instead of the compression spring member 61 .

Next, the upstream mounting portion 110 will be described. On the upstream side of the opening/closing cover 118 in the main body 102, a locking block 62 is pivotally supported by a horizontally arranged pivot pin 63. As shown in FIG. A locking pin 65 is provided to extend downstream from the upper end of the locking block 62 . A locked portion 118c is provided at the upstream end of the opening/closing cover 118 . In the state shown in FIG. 17A, that is, in the state in which the opening/closing cover 118 is closed, the tip of the locking pin 65 is in a position where it can be locked by coming into contact with the locked portion 118c from above.

A tension spring member 64 is coupled to the upstream side of the lower end of the locking block 62 , and a rotational biasing force acts on the locking block 62 to rotate it clockwise with the pivot pin 63 as a fulcrum. As a result, when the opening/closing cover 118 is closed, the locking pin 65 abuts against the locked portion 118c from above and presses the upstream end of the opening/closing cover 118 downward (arrow z2).

That is, in the state shown in FIG. 17A , downward pressing forces are applied to the opening/closing cover 118 by the downstream side mounting portion 109 and the upstream side mounting portion 110 at the respective distal ends of the opening/closing cover 118 on the downstream side and the upstream side. It is in a state where As a result, the opening/closing cover 118 is pressed against the tape conveying portion 103 and is kept in engagement with the positioning sprocket 107 and the discharging sprocket 108 of the carrier tape 20, and further attached to the main body portion 102 of the tape feeder 101. state is preserved. Further, by applying a downward pressing force to the opening/closing cover 118 , the lower surface of the carrier tape 20 is brought into close contact with the body portion 102 , and the upper surface of the carrier tape 20 is brought into close contact with the lower surface of the opening/closing cover 118 . As a result, the carrier tape 20 is guided by the main body portion 102 and the lower surface of the opening/closing cover 118, so that the carrier tape 20 can be transported stably. That is, the downstream side mounting portion 109 and the upstream side mounting portion 110 constitute a cover mounting portion that presses the opening/closing cover 118 against the tape conveying portion 103 and is mounted on the main body portion 102 of the tape feeder 101 .

A tape cover 124 is provided on the downstream side of the tape pressing member 130 along the tape transport path 4 up to a position before the component supply position. The distal end portion of the tape cover 124 on the downstream side functions as a peeling portion that peels off the cover tape 20a by rotating the cover tape 20a peeled off from the carrier tape 20 on the downstream side and folding it back toward the upstream side (Fig. 10).

The tape feeder 101 includes a driving peeling roller 122 and a driven peeling roller 123, which are a pair of rollers for picking up the cover tape 20a peeled from the carrier tape 20 in this manner. The driven peeling roller 123 , which is one roller of the pair of rollers, is attached to the opening/closing cover 118 . The driving peeling roller 122 , which is the other roller of the pair of rollers, is provided at the tip of the tape pressing member 130 arranged along the tape conveying path 4 .

Rotation of a transmission gear mechanism 117 driven to rotate by a motor 105 is transmitted to the driven peeling roller 122 via an idler 116 . The motor 105, the transmission gear mechanism 117, and the idler 116 constitute roller driving means for driving the driving peeling roller 122, which is the other roller of the pair of rollers.

The cover tape 20a peeled by the peeling portion at the tip of the tape cover 124 is folded back toward the upstream side. By driving the driving peeling roller 122 in a state where the cover tape 20a is sandwiched between the pair of the driving peeling roller 122 and the driven peeling roller 123, the cover tape 20a is picked up and stored in the cover tape storage provided in the main body 102. It is fed into section 102b.

FIG. 17B shows a state in which the upstream mounting portion 110 is operated to unlock the upstream side of the opening/closing cover 118 and the opening/closing cover 118 is opened. When the opening/closing cover 118 is opened, the locking block 62 is rotated in the unlocking direction (arrow z3) against the biasing force of the tension spring member 64 .
