Description

The present invention relates to a feeder device mounted on a component mounting machine, and more particularly to a tape peeling mechanism for peeling a cover tape from a carrier tape containing parts.

Facilities for producing substrates on which a large number of components are mounted include solder printing machines, component mounting machines, reflow machines, and board inspection machines. It has become common to connect these facilities to form a substrate production line. Of these, the component mounting machine includes a board transfer device, a component supply device, a component transfer device, and a control device. As a typical example of the parts supply device, there is a feeder device of a type that feeds out a parts supply tape that stores and holds a large number of parts at a predetermined pitch. The component supply tape comprises a carrier tape in which components are stored in a large number of component storage portions, and a cover tape that is adhered to the upper surface of the carrier tape to prevent the components from falling off. Therefore, the feeder device includes at least one of a tape peeling mechanism for peeling the cover tape from the carrier tape and a tape cutting mechanism for opening the cover tape to open the component storage portion. A technical example relating to this type of feeder device is disclosed in Patent Document 1.

In the electronic component supply device of Patent Document 1, an electronic component exposure device that exposes the components of the component storage portion is arranged between the first and second feeders that convey the component storage tape (component supply tape). .. Further, the electronic component exposing device includes a cutting device for cutting the cover tape along the feeding direction, an opening device for opening the cut cover tape, and a tongue portion for introducing the cover tape into the cutting device. According to this, it is possible to realize an electronic component supply device that can supply components without peeling the cover tape from the carrier tape and has less damage to the components.

Japanese Unexamined Patent Publication No. 2011-29260

By the way, in Patent Document 1, the tongue portion arranged on the front side of the cutting device facilitates cutting by scooping the cover tape from the carrier tape and spreading the space between the two. However, when the tip of the component supply tape arrives, the tongue portion cannot always enter between the cover tape and the carrier tape well. If the tongue portion is located above the cover tape, the entire parts storage tape will slip under the tongue portion, and parts cannot be supplied. Further, if the tongue portion hits the carrier tape, the carrier tape may be torn or the parts may be damaged.

As a countermeasure against this, in the embodiment of Patent Document 1, a notch is made in advance in the tape length direction from the tip of the cover tape so that the tongue portion can easily enter between the cover tape and the carrier tape. Further, in the feeder device which does not have a cutting device and only peels off, the portion near the tip of the cover tape is peeled off in advance to facilitate the entry of the tongue portion. However, the setup work of making a notch in the cover tape and peeling off the cover tape in advance is complicated because it is required every time the reel around which the component supply tape is wound is replaced.

The present invention has been made in view of the above-mentioned problems of the background technology, and provides a feeder device capable of reliably peeling off the cover tape without damaging the parts and requiring no setup work for the tip of the parts supply tape. It is an issue to be solved.

The invention of the feeder device according to claim 1 for solving the above problems is set on a carrier tape in which parts are housed in a large number of parts storage portions formed side by side in the tape length direction, and on the upper surface of the carrier tape. A tape feeding mechanism that feeds out a component supply tape made of a cover tape that is adhered to the adhesive portion and prevents the component from falling off from the component storage portion, and a peeling member that enters the tip surface of the component supply tape that is fed out in the feeding direction. As the component supply tape is unwound, the peeling member is displaced upward to peel the cover tape from the adhesive portion set on the upper surface of the carrier tape, and the component of the carrier tape is peeled off at the component supply position. A feeder device including a tape peeling mechanism that enables the parts to be supplied from the storage portion, and the tape peeling mechanism is interchangeably attached to the feeder device main body according to the type of the parts supply tape. The entire height is automatically adjusted up and down by the mounting portion according to the displacement of the height of the peeling member with respect to the component supply tape.

According to the invention of the feeder device according to claim 1, when the component supply tape is unwound and the tip surface thereof arrives, the release member enters the tip surface of the carrier tape on the lower side of the component supply tape. Therefore, there is no problem that the entire component supply tape slips under the peeling member. Further, after entering the tip surface of the carrier tape, the peeling member is displaced upward as the component supply tape is unwound, and naturally rides on the upper surface of the carrier tape. Therefore, the peeling member settles between the carrier tape and the cover tape, and does not damage the parts in the parts storage portion. Further, after that, the peeling member advances between the carrier tape and the cover tape, so that the cover tape can be reliably peeled off. Further, the conventional setup work of making a notch in the cover tape near the tip of the component supply tape or peeling off the cover tape in advance is unnecessary.

(2. Configuration of parts supply tape 8)
Next, a detailed configuration of the component supply tape 8 that is wound and held by the supply reels 13 and 14 and unwound will be described with reference to FIGS. 2 and 3. FIG. 2 is a plan view showing a portion of the component supply tape 8 including the tip surface 8T in the feeding direction. Further, FIG. 3 is a view taken along the line AA of FIG. 2, which is a cross-sectional view showing a state in which the component P is housed in the component supply tape 8. As shown in FIGS. 2 and 3, the component supply tape 8 includes a cover tape 81 and a carrier tape 82. The carrier tape 82 is formed by attaching a bottom tape 84 to the lower side of the base tape 83.

The base tape 83 is made of a flexible material such as a paper material or a resin. A large number of rectangular component storage portions 831F and 831 are bored at a position slightly to the right of the center of the base tape 83 in the tape width direction at equal pitches in the tape length direction. The component P is not stored in the component storage section 831F at several locations near the tip. The parts P are stored and held in the parts storage units 831 after a few parts are excluded. A large number of engaging holes 832 are formed in parallel with the side edges at equal pitches in the tape length direction near the left side edge of the base tape 83.

A bottom tape 84 is attached to the lower surface of the base tape 83. The bottom tape 84 is formed of a thin and transparent polymer film. The width dimension of the bottom tape 84 matches the width dimension of the base tape 83. An engaging hole 841 is also formed in the bottom tape 84 so as to overlap the engaging hole 832 of the base tape 83.

On the other hand, the cover tape 81 is detachably adhered to the upper surface of the base tape 83. More specifically, an adhesive portion 833 extending in the tape length direction is set on the upper surface between the component storage portion 831 of the base tape 83 and the right side edge. Further, an adhesive portion 834 extending in the tape length direction is set on the upper surface between the component storage portion 831 and the engagement hole 832 of the base tape 83. The portions of the cover tape 81 near both edges are adhered to the two adhesive portions 833 and 834. The cover tape 81 is formed of a thin and transparent polymer film. The width of the cover tape 81 is smaller than that of the base tape 83 and covers the component storage portion 831 but does not cover the engaging holes 832 and 841. With the above-described configuration, the component P is stored and held in each component storage section 831 of the base tape 83, and is prevented from falling off by the bottom tape 84 and the cover tape 81.

(3. Configuration of feeder device 1 of the embodiment)
Next, the detailed configuration of the feeder device 1 will be described with reference to FIG. FIG. 4 is a side view showing a detailed configuration of the feeder device 1 of the embodiment. In the feeder device 1, the rail 2, the rear tape feeding mechanism 3, the front tape feeding mechanism 4, the tape peeling mechanism 5, the next tape control mechanism 6, the control unit 7, and the like are assembled to the two side plates forming the main body 12. It is composed of. The two side plates forming the main body 12 are arranged in parallel with each other by the width direction of the flat shape, and the side plates on the front side of the paper surface are omitted in FIG.

The rail 2 is a member that guides the feeding of the component supply tape 8 on the upper surface thereof. The rail 2 is formed of an elongated plate-shaped member that is slightly wider than the tape width of the component supply tape 8. The rail 2 is arranged so as to be inclined from a substantially intermediate height behind the main body 12 to an upper part in front of the main body 12. The insertion port 21 formed on the upper side of the rear end of the rail 2 is capable of vertically stacking the component supply tapes 8 drawn from the two supply reels 13 and 14. A levitation prevention member 22 is provided near the middle of the rail 2 in the length direction. The levitation prevention member 22 is pressed against the upper surface of the rail 2 by the torsion spring 23. The levitation prevention member 22 prevents the levitation by sandwiching the component supply tape 8 between the rail 2 and the rail 2 so that the component supply tape 8 can be fed out. The component supply position 15 is set on the upper side near the front end of the rail 2. A guide member (not shown) for holding the width direction of the component supply tape 8 is erected upward from both side edges of the rail 2.

The rear tape feeding mechanism 3 is arranged at the lower part of the rail 2 near the rear. The rear tape feeding mechanism 3 is composed of a first motor 31, a first gear 32, a second gear 33, a first sprocket 34, a second sprocket 35, and the like. The output shaft of the first motor 31 is rotationally connected to the first sprocket 34 and the second sprocket 35 via the first gear 32 and the second gear 33 by gear coupling. The output teeth of the first sprocket 34 and the second sprocket 35 project upward from the gap formed in the rail 2 and engage with the engaging holes 832 and 841 of the component supply tape 8. Therefore, when the motor 31 is intermittently driven by a constant amount of rotation, the rear tape feeding mechanism 3 intermittently feeds the component supply tape 8 forward along the upper surface of the rail 2 by a constant pitch.

The front tape feeding mechanism 4 is arranged at the lower part of the rail 2 near the front. The front tape feeding mechanism 4 is composed of a second motor 41, a third gear 42, a fourth gear 43, a third sprocket 44, a fourth sprocket 45, and the like. The output shaft of the second motor 41 is rotationally connected to the third sprocket 44 and the fourth sprocket 45 via the third gear 42 and the fourth gear 43 by gear coupling. The output teeth of the third sprocket 44 and the fourth sprocket 45 project upward from the gap formed in the rail 2 and engage with the engaging holes 832 and 841 of the component supply tape 8. Therefore, when the second motor 41 is intermittently driven by a constant amount of rotation in synchronization with the first motor 31, the front tape feeding mechanism 4 moves the component supply tape 8 forward along the upper surface of the rail 2. Intermittently feeds at a constant pitch.

The next tape control mechanism 6 is arranged above the rail 2 near the rear, in other words, above the rear tape feeding mechanism 3. The next tape control mechanism 6 controls the feeding of the two component supply tapes 8 inserted so as to overlap the insertion ports 21 from the two supply reels 13 and 14. That is, the next tape control mechanism 6 allows the first component supply tape 8 currently in use to be fed out, and holds the vicinity of the tip of the second component supply tape 8 to be used next. Then, the next tape control mechanism 6 automatically starts feeding out the second component supply tape 8 when the first component supply tape 8 runs out, and allows the insertion of the third component supply tape 8.

The control unit 7 is arranged below the main body 12. The control unit 7 includes a microprocessor, a memory, a driver, a communication unit, and the like (not shown), and operates by software. When the feeder device 1 is mounted on the pallet member 11, it is communicatively connected to the control device 96 via a connector 71 provided on the front surface of the main body 12. As a result, the control unit 7 can exchange necessary information with the control device 96. The control unit 7 controls the drive currents of the first motor 31 of the rear tape feeding mechanism 3 and the second motor 41 of the front tape feeding mechanism 4 via a driver. Further, the control unit 7 detects that the front end surface 8T and the rear end surface of the component supply tape 8 have passed through the tape end detection sensor based on the detection result of the tape end detection sensor (not shown).

(4. Configuration and mounting method of tape peeling mechanism 5)
The tape peeling mechanism 5 is arranged above the rail 2 near the front, in other words, above the front tape feeding mechanism 4. FIG. 5 is a perspective view of the tape peeling mechanism 5. The tape peeling mechanism 5 is a mechanism that peels the cover tape 81 of the component supply tape 8 to be fed out from the carrier tape 82 and enables the component P to be supplied from the component storage portion 831 of the carrier tape 82 at the component supply position 15. A plurality of types of tape peeling mechanisms 5 are prepared according to the type of component supply tape 8, and are interchangeably attached to the feeder device 1.

As shown in FIG. 5, the tape peeling mechanism 5 has an upper wall 51, a right side wall 52, and a left side wall 53 and is formed in a downwardly open U-shaped cross section, and is long in the feeding direction. The upper wall 51 is slightly bent in a "he" shape at a bending position 511 slightly behind the middle in the front-rear direction. The pressed portion 512 is formed behind the bent position 511 of the upper wall 51. The pressed portion 512 is formed by cutting and bending a part of the upper wall 51, rises toward the rear, and separates from the upper wall 51. The rear tip portion of the pressed portion 512 is covered with the pressed member 513.

Front side engaging portions 521 and 513 projecting forward are formed at the lower front portion of the right side wall 52 and the left side wall 53 in the feeding direction, respectively. Rear engaging portions 522 and 532 are formed on the lower portion of the right side wall 52 and the left wall 53 near the rear in the feeding direction, respectively. The rear engaging portions 522 and 532 have a shape in which the lower side of a long hole long in the vertical direction is opened forward. The front engaging portions 521 and 513 and the rear engaging portions 522 and 532 are portions for attaching the tape peeling mechanism 5 to the main body portion 12.

A rectangular notch 54 is formed on the front side of the upper wall 51 by cutting out about the right half in the front-rear direction and the width direction. A peeling member 55 is arranged inside the notch 54. The peeling member 55 has a tip portion 551 facing the component supply tape 8 to be unwound thin in the vertical direction. Further, the peeling member 55 is formed so as to gradually become thicker from the tip portion 551 toward the rear side of the member (front of the feeder device 1) (details will be described later).

Further, the peeling member 55 has a side surface that is inclined toward the rear of the member from the tip portion 551. Therefore, the width dimension of the peeling member 55 is small at the tip portion 551 and gradually increases toward the rear of the member. The tip portion 551 of the peeling member 55 is sharply formed and is suitable for peeling the cover tape 81. The portion of the peeling member 55 near the rear is formed with a constant thickness and a constant width, and is fixed to the right side wall 52. In this vicinity, only a part of the notch 54 near the center is open. The area of the notch 54 near the front where the peeling member 55 is not arranged is set at the component supply position 15.

A plate-shaped opening member 56 is arranged above the peeling member 55 and the upper wall 51. The opening member 56 is fixed to the left side wall 53 so that a slight gap is formed between the opening member 56 and the upper wall 51. The tip 561 of the opening member 56 facing the component supply tape 8 is arranged slightly behind the tip 551 of the peeling member 55 (front of the feeder device 1). The tip 561 of the opening member 56 has a small width dimension and is within the width range of the peeling member 55. The width of the opening member 56 gradually increases toward the rear of the member (front of the feeder device 1). The left side surface of the opening member 56 is an inclined surface 562 inclined toward the left side wall 53, and the right side surface is a parallel surface 563 parallel to the right side wall 52. At a position closer to the rear of the opening member 56, the inclined surface 562 on the left side projects to the left side in the width direction with respect to the peeling member 55.

A feeder mark (not shown) indicating a reference position is attached to the front upper part of the main body 12 of the feeder device 1. A mark confirmation hole 564 is formed in front of the component supply position 15 of the opening member 56 so that the substrate camera 946 can image the feeder mark with the tape peeling mechanism 5 attached. Similarly, a mark confirmation hole 514 is formed at a corresponding position on the upper wall 51.

FIG. 6 is a perspective view of a state in which the tape peeling mechanism 5 is attached to the main body 12 as viewed from a direction different from that of FIG. As shown, the tape guide 16 is arranged on the upper part of the front surface of the main body 12, and the connector 71 is arranged below the tape guide 16. The width of the central portion of the tape guide 16 is wider than the width of the component supply tape 8, and the width of the narrowed upper portion is narrower than the width of the component supply tape 8. The tape guide 16 guides the feeding of the component supply tape 8 that has finished supplying the component P. The connector 71 plays a role of supplying power to the feeder device 1 and communicating and connecting the control unit 7 and the control device 96 described above.

As shown in FIG. 6, behind the tape guide 16 of the main body portion 12, front mounting protrusions 17 are projected on both the left and right sides. Further, the rear mounting protrusions 18 are projected on both the left and right sides at a predetermined position of the main body 12 which is separated from the front mounting protrusion 17 by a distance smaller than the total length of the tape peeling mechanism 5. Further, a mounting lever 19 is arranged at an obliquely rear upper portion of the rear mounting protrusion 18 of the main body 12. A flat plate-shaped pressing member 191 is provided at the tip of the mounting lever 19. The mounting lever 19 swings around the shaft portion 192 and is operated in a vertically standing release state and a forward tilted mounting state. Further, the pressing member 191 of the mounting lever 19 is urged downward by the urging member (not shown) in the mounting state shown in FIG.

When attaching the tape peeling mechanism 5 to the main body 12, first, the attachment lever 19 is raised to release the tape. Next, the front engaging portions 521 and 531 of the tape peeling mechanism 5 are engaged with the lower side of the front mounting protrusion 17 of the main body portion 12, and the entire tape peeling mechanism 5 is placed on the upper side of the main body portion 12. , The rear mounting protrusion 18 is engaged with the rear engaging portions 522 and 532. Thirdly, the mounting lever 19 is tilted to operate the mounting state. This completes the mounting operation. In the reverse removal operation, the mounting lever 19 is raised from the mounted state to release it, and the tape peeling mechanism 5 is removed upward from the main body 12.

In the mounted state of the tape peeling mechanism 5, the pressing member 191 of the mounting lever 19 presses the pressed portion 512 of the peeling member 55. As a result, the tape peeling mechanism 5 is urged so as to be vertically movable from above toward the rail 2. Here, since the component supply tape 8 to be unwound advances between the tape peeling mechanism 5 and the rail 2, the upper wall 51 of the tape peeling mechanism 5 is urged toward the component supply tape 8 and the rail 2 from above. Rail. Then, the tip surface 8T of the component supply tape 8 in the feeding direction faces the tip portion 551 of the peeling member 55 as shown in FIG. 7.

FIG. 7 is a side view showing the detailed shape of the tip portion 551 of the peeling member 55 and the height relationship of the component supply tape 8 with the tip surface 8T. As shown, the tip portion 551 of the peeling member 55 includes a tip upper edge 552 arranged below the height of the upper surface of the carrier tape 82, and a lower surface 553 that descends from the tip upper edge 552 toward the rear. It is formed. The lower surface 553 is chamfered and rounded at a position close to the upper edge 551 of the tip, and is connected to the lower surface 557 parallel to the component supply tape 8. The length L1 of the lower surface 553 in the feeding direction is formed to be shorter than the distance D1 between the component storage portion 831 at the head of the component supply tape 8 and the tip surface 8T described above (see FIG. 9). On the other hand, the upper surface 554 of the tip portion 551 gradually rises from the tip upper edge 552 toward the rear. Therefore, the peeling member 55 gradually becomes thicker toward the rear of the member.

The height relationship between the tape peeling mechanism 5, the component supply tape 8, and the rail 2 is stabilized by urging the tape peeling mechanism 5 toward the component supply tape 8 and the rail 2 from above. That is, when the height of the release member 55 is displaced with respect to the component supply tape 8, the overall height of the tape release mechanism 5 is automatically adjusted up and down by the elongated hole shape of the rear engaging portions 522 and 532. Will be done.

On the other hand, the positional relationship between the peeling member 55 and the component supply tape 8 in the tape width direction is shown in FIG. FIG. 9 is a plan view showing the positional relationship between the peeling member 55 and the component supply tape 8 in the tape width direction. The peeling member 55 is arranged with the tip portion 551 between the left and right adhesive portions 833 and 834 in the tape width direction, specifically between the right adhesive portion 833 and the component supply portion 831. Further, the peeling member 55 projects outward from the adhesive portion 833 on the right side in the tape width direction, and does not reach the adhesive portion 834 on the left side.

(5. Operation of feeder device 1 of the embodiment)
Next, the operation of the feeder device 1 of the embodiment configured as described above will be described. When the supply reels 13 and 14 are set in the feeder device 1 and the component supply tape 8 is unwound, as shown in FIGS. 2 and 7, the tip surface 8T of the component supply tape 8 and the tip portion 551 of the peeling member 55 And face each other. Then, when the component supply tape 8 is further extended, the tip upper edge 552 of the tip portion 551 of the peeling member 55 first enters the component supply tape 8. Here, as can be seen from the height relationship shown in FIG. 7, the tip upper edge 552 usually enters the position 82X lower than the upper edge of the tip surface of the carrier tape 82. Therefore, there is no problem that the entire component supply tape 8 slips under the peeling member 55.

Since the peeling member 55 that has entered the position 82X is lowered as the lower surface 553 of the tip portion 551 moves backward, the peeling member 55 is gradually displaced upward as the component supply tape 8 is unwound. As a result, the peeling member 55 naturally rides on the carrier tape 82 through the path 82Y and settles between the carrier tape 82 and the cover tape 81. At this time, since the length L1 of the lower surface 553 is formed to be smaller than the distance D1 of the component supply tape 8, the tip portion 551 of the peeling member 55 covers the carrier tape 82 and the cover before reaching the leading component storage portion 831. It can be settled between the tape 81 and the tape 81. Further, in the path 82Y of the carrier tape 82, an intrusion trace in which a small part of the member is scraped off or the member is deformed such as compression remains. After that, the peeling member 55 advances between the carrier tape 82 and the cover tape 81 as the component supply tape 8 is unwound. As a result, stable peeling is continued, and the peeling member 55 does not deviate from between the tapes 81 and 82.

Further, on the tip surface 8T of the component supply tape 8, the tip upper edge 552 of the tip portion 551 of the peeling member 55 may immediately enter between the cover tape 81 and the carrier tape 82. In this case, stable peeling is continued from the beginning of entry.

The tip portion 551 of the peeling member 55 is not limited to the shape shown in FIG. 7, and may be, for example, a modified example shown in FIG. FIG. 8 is a side view showing the detailed shape of the tip portion 591 of the peeling member 59 of the modified example. As shown, the tip portion 591 of the peeling member 59 of the modified example has an upper tip edge 592 arranged below the height of the upper surface of the carrier tape 82, and a lower surface 593 that descends from the upper tip edge 592 toward the rear. Is formed including. The lower surface 593 has a roundness approximated by two planes at a position close to the tip upper edge 592, and is connected to the lower surface 597 parallel to the component supply tape 8. On the other hand, the upper surface 594 of the tip portion 591 gradually rises from the tip upper edge 592 toward the rear. Therefore, the peeling member 59 gradually becomes thicker toward the rear of the member. Even if the peeling member 59 of the modified example is used, the action when entering the tip surface 8T of the component supply tape 8 does not change.

On the other hand, as shown in FIG. 9, the tip portion 551 of the peeling member 55 enters between the adhesive portion 833 on the right side of the component supply tape 8 and the component supply portion 831. As the component supply tape 8 is unwound, the peeling member 55 peels off the adhesive portion 834 on the right side, but does not peel off the adhesive portion 834 on the left side. Then, the component supply tape 8 is fed out to the front opening member 56 while the adhesive portion 833 on the right side is peeled off and the adhesive portion 834 on the left side maintains the adhesive state.

FIG. 10 is a view taken along the arrow BB of FIG. 6, and is a diagram for explaining the action of opening the component storage portion 831 of the component supply tape 8 by the opening member 56. The inclined surface 562 on the left side of the opening member 56 waits for the component supply tape 8 to be unwound, and gradually exerts the following action. That is, the opening member 56 raises the cover tape 81 that is peeled off from the adhesive portion 833 on the right side above the adhesive portion 834 on the left side that is not peeled off, and further folds the cover tape 81 back to the left side. As a result, the upper part of the component supply unit 831 is opened.

The state in which the upper portion of the component supply unit 831 is open is maintained even at the component supply position 15 in front of the peeling member 55, and the component P is suction-collected by the suction nozzle. Further, in the front tape guide 16, the component supply tape 8 is fed out with the cover tape 81 folded back to the left side. After that, the component supply tape 8 is collected with the cover tape 81 still adhered to the adhesive portion 834 on the left side of the carrier tape 82.

Therefore, there is no problem that the entire component supply tape 8 slips under the peeling member 55. Further, after entering the tip surface 8T of the carrier tape 82, the peeling member 55 is displaced upward as the component supply tape 8 is unwound, and naturally rides on the upper surface of the carrier tape 82. Therefore, the peeling member 55 settles between the carrier tape 82 and the cover tape 81, and does not damage the component P in the component storage portion 831. Further, after that, the peeling member 55 advances between the carrier tape 82 and the cover tape 81, so that the cover tape 81 can be reliably peeled off. Further, the conventional setup work of making a notch in the cover tape near the tip of the component supply tape 8 or peeling off the cover tape in advance is unnecessary.

Further, in the feeder device 1 of the embodiment, the peeling member 55 includes a tip upper edge 552 arranged below the height of the upper surface of the carrier tape 82, and a lower surface 553 that descends from the tip upper edge 552 toward the rear. It has a tip portion 551 that is formed and first enters the tip surface of the carrier tape 82. According to this, the tip upper edge 552 of the peeling member 55 can surely and easily enter the tip surface of the carrier tape 82. Further, the peeling member 55 is surely displaced upward by the action of the lower surface 553 that descends toward the rear. Therefore, the peeling member 55 can be quickly displaced between the carrier tape 82 and the cover tape 81 from the initial approach position.

Further, in the feeder device 1 of the embodiment, the length L1 of the lower surface 553 of the tip portion 551 of the peeling member 55 in the feeding direction is shorter than the distance D1 between the tip surface 8T of the carrier tape 82 and the component storage portion 831. According to this, the tip portion 551 of the peeling member 55 can settle between the carrier tape 82 and the cover tape 81 before reaching the leading component storage portion 831. Therefore, it is possible to reliably avoid the possibility that the peeling member 55 damages the component P in the component storage unit 831.

Further, in the feeder device 1 of the embodiment, the peeling member 55 enters a position lower than the upper edge of the tip surface of the carrier tape 82, and then leaves an entry mark on the carrier tape 82 as the component supply tape 8 is unwound. It displaces upward and settles between the carrier tape 82 and the cover tape 81. According to this, the peeling member 55 is displaced from the first approach position to the space between the carrier tape 82 and the cover tape 81, and thereafter settles between the carrier tape 82 and the cover tape 81, so that stable peeling can be performed. Will be continued.

Further, in the feeder device 1 of the embodiment, adhesive portions 833 and 834 extending in the tape length direction are set on the upper surface between the component storage portion 831 of the carrier tape 82 and the left and right side edges, respectively, and the peeling member In 55, the width dimension in the tape width direction is small at the tip portion 551 that first enters the tip surface of the carrier tape 82 and gradually increases toward the rear, and the tip portion 551 is formed by the left and right adhesive portions 833 in the tape width direction. It is placed between 834. According to this, the tip portion 551 of the peeling member 55 is located between the left and right adhesive portions 833 and 834 and peels off at least one of the adhesive portions 833 and 834, so that the tip portion 551 is outside the adhesive portions 833 and 834. The peeling operation is more stable than the configuration arranged in.

Further, in the feeder device 1 of the embodiment, the peeling member 55 projects outward from the adhesive portion 833 on the right side in the tape width direction and does not reach the adhesive portion 834 on the left side. According to this, since the adhesive portion 834 on the left side is not peeled off, the cover tape 81 can be collected in a state of being adhered to the carrier tape 82, and can be collected as compared with a configuration in which the cover tape 81 is completely peeled off from the carrier tape 82. The trouble of is reduced.

Further, in the feeder device 1 of the embodiment, the tape peeling mechanism 5 raises the cover tape 81 peeled from the adhesive portion 833 on the right side above the adhesive portion 834 on the left side which is not peeled off, and raises the component storage portion 831 of the carrier tape 82.
