Description

[Technical field]

[0001] The present invention relates to a component supplying device that conveys a carrier tape having a cover tape attached to a base tape containing components, and supplies the components to a component removal position. [Background technology]

[0002] Conventionally, there is known a component supplying device that supplies the components to a component removal position by conveying a carrier tape in which a cover tape is affixed to a base tape that stores the components, and is generally referred to as a tape feeder. The tape feeder has a configuration in which a main body portion in which a carrier tape conveying path is formed is provided with a conveying mechanism that conveys the carrier tape, and is configured to peel off the cover tape from the base tape before the carrier tape traveling on the conveying path reaches the component removal position, thereby enabling components to be removed at the component removal position.

[0003] In the tape feeder, the cover tape peeled off from the base tape of the carrier tape is stored in a storage section formed in the main body, and the cover tape stored in the storage section can be discharged from an outlet that opens at an end of the main body and connects to the storage section. The outlet is normally closed by a lid member, and when the cover tape that has accumulated in the storage section and has become an elastic mass presses the lid member from inside the storage section, the lid member is pushed open and the cover tape in the storage section is discharged (pops out) from the outlet (see, for example, Patent Document 1 below).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a component mounting device 1 equipped with a tape feeder, which is an embodiment of a component supply device of the present invention. The component mounting device 1 is a device that mounts components BH on a board KB, and is equipped with a board transport unit 12 on a base 11. The board transport unit 12 transports the board KB horizontally and positions it at a predetermined work position. For the sake of convenience, the transport direction of the board KB by the board transport unit 12 is referred to as the X direction, the horizontal direction perpendicular to the X direction is referred to as the Y direction, and the up-down direction is referred to as the Z direction. In addition, in the Y direction, the direction toward the center of the base 11 is referred to as the "front", and the direction toward the opposite side is referred to as the "rear".

[0011] 1, a mounting head 13 is provided above a base 11. The mounting head 13 is moved in the horizontal direction by a head moving mechanism (not shown). The mounting head 13 is provided with a plurality of nozzles 14 extending downward.

[0012] In Fig. 1, a dolly 15 is connected to the end of base 11 in the Y direction. Dolly 15 is equipped with a feeder base 15a and a reel holding section 15b. Tape feeders 16 are detachable from feeder base 15a, and a plurality of tape feeders 16 are mounted on feeder base 15a in a line in the X direction. Reel holding section 15b rotatably holds reel RL around which carrier tape CT transported by tape feeder 16 is wound.

[0013] First, the carrier tape CT will be described. As shown in Fig. 2, the carrier tape CT has a number of pockets PK for storing components arranged in a row, and a number of feed holes KH are arranged in a row parallel to the row of pockets PK.

[0014] 2, each pocket PK contains one component BH, and a cover tape TT is attached to the top surface of the carrier tape CT in a position that covers the pocket PK. In other words, the components BH are contained in the carrier tape CT covered by the cover tape TT.

[0015] 3, tape feeder 16 is configured with a main body 21 as a base that is detachably attached to feeder base 15a, and a transport path 21L that is a transport passage for carrier tape CT is formed within main body 21. A tape entrance 21A that is an entrance to transport path 21L is formed at the rear end of main body 21, and a tape exit 21B that is an exit from transport path 21L is formed at the front end of main body 21. The leading end of carrier tape CT pulled out from reel RL is inserted into tape entrance 21A.

[0016] 3, a sprocket 22 is provided on the upper front part of the main body 21. The sprocket 22 rotates with feed pins provided on the outer periphery engaged from below with feed holes KH provided in the carrier tape CT, thereby transporting the carrier tape CT to the tape outlet 21B side.

[0017] 3, a tape cover 24 that covers the carrier tape CT on the transport path 21L is provided on the upper part of the main body 21. The tape cover 24 is provided with a component removal opening 24K and a cover tape pull-out opening 24T.

[0018] The component removal opening 24K is an opening through which the mounting head 13 removes the component BH from the carrier tape CT with the nozzle 14, and the position directly below the component removal opening 24K is the position on the transport path 21L where the component BH is supplied, i.e., the component removal position 16T. The cover tape pull-out opening 24T is provided upstream (rear) of the component removal opening 24K. The cover tape TT peeled off from the base tape BT of the carrier tape CT traveling on the transport path 21L is pulled out above the tape cover 24 from the cover tape pull-out opening 24T.

[0019] 3, a pair of peeling rollers 23 are provided at the upper part of the middle part in the front-rear direction (Y direction) in the main body 21. In the component supply operation performed by the tape feeder 16, the carrier tape CT is sent to the tape outlet 21B by the sprocket 22, while the cover tape TT peeled from the base tape BT is pulled out from the cover tape pull-out opening 24T, and the pulled cover tape TT is pulled backward while being sandwiched by the peeling rollers 23. As a result, the component BH is exposed at the component removal position 16T, and the mounting head 13 can insert the nozzle 14 into the component removal opening 24K to remove the component BH. In this component supply operation, the pair of peeling rollers 23 function as a peeling section that peels the cover tape TT from the base tape BT of the carrier tape CT transported on the transport path 21L.

[0020] 3, a storage section 33 is formed at the rear inside the main body section 21 to store the cover tape TT peeled off from the base tape BT. The pair of peeling rollers 23 are positioned facing the storage section 33, and the cover tape TT (the cover tape TT peeled off from the base tape BT) that is sandwiched between the pair of peeling rollers 23 is sent to the storage section 33, where it is stored and accumulated. The storage section 33 has a shape in which a bottom surface 33M is inclined downward toward a discharge port 33K as shown in FIG. 3, and a vertical height 33H gradually increases toward the discharge port 33K.

[0021] 3 and 4 (FIG. 4 is an enlarged view of an area RY in FIG. 3), a discharge opening 33K for the cover tape TT is formed at the rear end of the main body 21. The discharge opening 33K is connected to the storage section 33, and the cover tape TT stored in the storage section 33 is discharged from the discharge opening 33K to the outside of the discharge opening 33K.

[0022] 3 and 4, a lid member 34 is provided at the rear end of the main body 21. The lid member 34 is a member that opens and closes the discharge opening 33K in order to take out the cover tape TT stored in the storage section 33 to the outside. As shown in Fig. 4, a swing shaft 35 is provided at the lower end of the discharge opening 33K in the main body 21, extending in the width direction (X direction) of the main body 21. The lower end of the lid member 34 is pivoted on the swing shaft 35, and the lid member 34 is freely swingable about the swing shaft 35 in the direction of opening and closing the discharge opening 33K.

[0023] Thus, in this embodiment, the cover member 34 has its lower end pivoted to a pivot shaft 35 provided on the main body portion 21, and pivots around the pivot shaft 35 to open and close the discharge outlet 33K of the cover tape TT, which opens into the main body portion 21 and is connected to the storage portion 33.

[0024] A knob 36 is provided on the rear surface of the lid member 34. An operator can manually swing the lid member 34 around the swing shaft 35 by pinching the knob 36 and operating the lid member 34.

[0025] 4, when the upper end of the lid member 34 is located directly above the pivot shaft 35 and the lid member 34 abuts against the end face 33T of the discharge outlet 33K, the discharge outlet 33K is closed by the lid member 34. The position of the lid member 34 that closes the discharge outlet 33K in this manner is hereinafter referred to as the "closed position."

[0026] 4, a magnet 41 is provided in the main body 21 above the discharge outlet 33K so as to be exposed to or in close proximity to the end surface 33T of the discharge outlet 33K. Corresponding to the magnet 41, a plate-shaped magnetic body 42 is provided on the upper end of the lid member 34.

[0027] The magnet 41 and the magnetic body 42 come into contact with each other when the cover member 34 is in the closed position, and attract each other by the mutually acting magnetic force. Therefore, even if the cover member 34 in the closed position receives a force (hereinafter referred to as an "opening direction acting force") acting in a direction to open the discharge port 33K (a direction in which the upper end falls backward around the swing shaft 35; hereinafter referred to as the "opening direction"), the cover member 34 maintains its state in the closed position as long as the opening direction acting force does not exceed the force (hereinafter referred to as the "holding force") that holds the cover member 34 in the closed position by the magnet 41 and the magnetic body 42 attracting each other.

[0028] The above-mentioned "opening direction acting force" includes the force (pressing force) of the cover tape TT, which is stored and accumulated in the storage section 33 and elastically compressed into a lump, pressing the lid member 34 backward from inside the storage section 33, as well as the force (pulling force) of an operator pinching the knob portion 36 and pulling the lid member 34 backward; however, in the following explanation, the opening direction acting force refers to the pressing force of the cover tape TT inside the storage section 33 pressing the lid member 34 from inside the storage section 33.

[0029] 4, a contact portion 43 is provided in front of the oscillation shaft 35 inside the main body portion 21. In this embodiment, the contact portion 43 is made of a cylindrical member extending in the width direction (X direction) of the main body portion 21.

[0030] In Fig. 4, a cantilever-shaped elastic piece 34D is provided on the lower part of the cover member 34. In this embodiment, the elastic piece 34D is formed as a part of the cover member 34. Therefore, when the cover member 34 swings around the swing shaft 35, the elastic piece 34D also swings together with the cover member 34 around the swing shaft 35. The elastic piece 34D extends downward from the lower part of the cover member 34, and when the cover member 34 is in the closed position, it is located between the swing shaft 35 and the abutment portion 43, but at a position separated from the abutment portion 43 (Fig. 4).

[0031] 4, the cover member 34 has a protruding portion 34H that protrudes forward from its front surface. In this embodiment, the protruding portion 34H has a shape like an isosceles triangle that is long in the vertical direction, with a first side 34a, which is one of the two long sides, aligned along the front surface 34M of the cover member 34, and an intersection 34K of a second side 34b, which is the other of the two long sides, and a third side 34c, which is the short side, located near the upper end of the cover member 34. Therefore, the protruding portion 34H has a shape in which the protruding amount MD into the storage section 33 gradually increases from the lower end side to the upper end side of the cover member 34 when the cover member 34 is in the closed position.

[0032] When an opening force acts on the overhanging portion 34H of the cover member 34 located at the closed position, and the force exceeds the force (the holding force described above) by which the magnet 41 and the magnetic body 42 hold the cover member 34 at the closed position, the cover member 34 swings in the opening direction around the swing shaft 35 (FIG. 4→FIG. 5(a)). When the cover member 34 swings in the opening direction from the closed position, the elastic piece 34D swings in the opening direction around the swing shaft 35 together with the cover member 34 (FIG. 6(a)→FIG. 6(b)), and the cover member 34 stops at a position where the elastic piece 34D of the cover member 34 swings from the closed position and abuts against the abutment portion 43 from the rear. Hereinafter, the position where the cover member 34 stops as the elastic piece 34D of the cover member 34 swings from the closed position in this manner abuts against the abutment portion 43 is referred to as the "middle open position". When the cover member 34 is located at the middle open position, the discharge port 33K is slightly opened (FIG. 5(a)).

[0033] As described above, the protrusion 34H has a shape such that the amount of protrusion MD into the storage section 33 increases from the lower end side to the upper end side of the lid member 34. Therefore, even when the lid member 34 is positioned in an intermediate open position in which the discharge outlet 33K is slightly open, the protrusion 34H remains positioned within the storage section 33, and the discharge outlet 33K is maintained in a state in which it is essentially closed by the lid member 34.

[0034] As described above, when the lid member 34 oscillates from the closed position, the elastic piece 34D abuts against the abutment portion 43, causing the lid member 34 to stop in the intermediate open position. In this embodiment, the elastic piece 34D, which oscillates around the oscillating axis 35 together with the lid member 34, and the abutment portion 43 provided on the main body portion 21 serve as an intermediate open position stopping means for stopping the lid member 34 in the intermediate open position.

[0035] When the cover member 34 is stationary in the intermediate open position, an opening direction acting force acts on the cover member 34, causing the cover member 34 to swing in the opening direction around the swing shaft 35, and the elastic piece 34D swings in the opening direction together with the cover member 34. As a result, the elastic piece 34D is pressed relatively backward by the contact portion 43 and elastically deforms, while moving its tip along the outer shape (circular in this case) of the contact portion 43 (FIG. 6(b)→FIG. 6(c)). Then, when the tip of the elastic piece 34D separates from the contact portion 43, the elastic piece 34D separates from the contact portion 43 and returns to the shape before elastic deformation (FIG. 6(d)). As a result, the cover member 34 loses the force resisting the opening direction acting force, and swings in the opening direction under its own weight (FIG. 6(d)→FIG. 6(e), FIG. 5(a)→FIG. 5(b)).

[0036] In this embodiment, when an opening direction force, which is a force (pushing force) in a direction to open the discharge outlet 33K, acts on the lid member 34 stopped in the intermediate open position, the elastic piece 34D abutting against the abutment portion 43 elastically deforms as the lid member 34 swings, and moves its tip along the outer shape of the abutment portion 43, and when the tip moves away from the abutment portion 43, the lid member 34 swings in the direction to open the discharge outlet 33K.

[0037] Lid member 34, which has swung in the opening direction under its own weight as described above, comes to rest in that position as a part of it abuts against stopper surface 21M of main body 21 (FIG. 5(b)). In this state where a part of lid member 34 is abutting against stopper surface 21M and is stationary, protrusion 34H of lid member 34 is located outside storage section 33, and discharge port 33K is open. The position of lid member 34 where discharge port 33K is open in this manner is hereinafter referred to as the "open position."

[0038] When component mounting device 1 having tape feeder 16 of the above configuration as a component supplying device performs a component mounting operation of mounting components BH onto board KB, first, board KB is supplied from outside component mounting device 1. After board KB is supplied, board transport section 12 operates to carry in board KB and position it at a predetermined work position. After board transport section 12 positions board KB at the work position, each tape feeder 16 starts a component supplying operation to continuously supply components BH to component removal opening 24K.

[0039] When each tape feeder 16 starts its component supplying operation, the mounting head 13 uses the nozzle 14 to suck and pick up the component BH that the tape feeder 16 supplies to the component removal position 16T. After picking up the component BH from the tape feeder 16, the mounting head 13 moves above the board KB and mounts the component BH at the target component mounting position determined on the board KB. Then, when the mounting head 13 has mounted all the components BH to be mounted on the board KB, the board transport unit 12 operates and transports the board KB out of the component mounting device 1. This completes the component mounting operation for one board KB.

[0040] In the component mounting work proceeding in this manner, the component supply operation continues in each tape feeder 16, and thus the operation of peeling the cover tape TT from the base tape BT of the carrier tape CT also continues. Therefore, the cover tape TT peeled from the base tape BT accumulates in the storage section 33 of each carrier tape CT (FIG. 7(a)→FIG. 7(b)).

[0041] As described above, the storage section 33 has a shape in which the bottom surface 33M is inclined downward toward the discharge outlet 33K, and the vertical height 33H gradually increases toward the discharge outlet 33K. Therefore, the cover tape TT sent into the storage section 33 by the pair of peeling rollers 23 is accumulated evenly in the storage section 33 without causing unevenness such as solidification at a specific location in the storage section 33 (FIG. 7(b)).

[0042] As described above, the cover tape TT accumulated in the storage section 33 is elastically compressed into a lump, and presses the lid member 34 located in the closed position with a pressing force P (the aforementioned opening direction acting force) in a direction from the inside of the storage section 33 to the outside (the rear of the main body section 21) (FIG. 8(a)). This pressing force P acts almost uniformly in the vertical direction of the lid member 34 (projection section 34H) (FIG. 9). When the pressing force P becomes large and exceeds the aforementioned holding force by the magnet 41 and the magnetic body 42, the lid member 34 swings in the opening direction from the closed position (FIG. 8(a)→FIG. 8(b)). At this time, of the forces distributed above and below the projection section 34H, the force pressing the upper half of the lid member 34, which is farther from the swing shaft 35, is more dominant than the force pressing the lower half of the lid member 34 (projection section 34H), which is closer from the swing shaft 35, and swings the lid member 34 in the opening direction.

[0043] Lid member 34, which has swung in the opening direction from the closed position as described above, comes to rest in the intermediate open position (FIG. 8(b)) as elastic piece 34D comes into contact with contact portion 43 (FIG. 6(a) →FIG. 6(b)). With lid member 34 resting in the intermediate open position in this manner, as described above, overhanging portion 34H of lid member 34 is still located within storage portion 33, and outlet 33K is substantially closed by lid member 34, so that cover tape TT within storage portion 33 is not discharged (does not pop out) from outlet 33K.

[0044] In this manner, the tape feeder 16 in this embodiment is capable of stopping the lid member 34 at an intermediate open position between the closed position and the open position, so that the lid member 34 can stop (temporarily stop) at a position (intermediate open position) where the discharge port 33K is open but the cover tape TT in the storage section 33 cannot be discharged from the discharge port 33K while moving from the closed position to the open position. At the intermediate open position, the overhanging portion 34H of the lid member 34 is located within the storage section 33 (it remains located within the storage section 33 from the closed position), so that the cover tape TT in the storage section 33 cannot be discharged from the discharge port 33K.

[0045] In other words, in this embodiment, the "intermediate open position" means a position between the closed position that closes the discharge outlet 33K and the open position where the cover tape TT in the storage section 33 can be discharged, and means a position where the cover tape TT in the storage section 33 cannot be discharged.

[0046] As described above, when the component supply operation by the tape feeder 16 continues with the lid member 34 in the intermediate open position, the cover tape TT peeled off from the base tape BT is further accumulated in the accommodation section 33. This increases the pressing force P acting on the lid member 34 (projection section 34H), and the lid member 34 swings in the opening direction from the intermediate open position while bending the elastic piece 34D (Fig. 6(b) → Fig. 6(c) → Fig. 6(d)). Then, when the tip of the elastic piece 34D swings away from the abutment section 43 (Fig. 6(d) → Fig. 6(e)), the lid member 34 swings under its own weight and is positioned in the open position.

[0047] When the lid member 34 is located at the open position (stationary), the cover tape TT in the storage section 33 is released from the compressed state in the storage section 33, and is discharged from the discharge port 33K with force (FIG. 10). Thus, in this embodiment, when a certain amount of the cover tape TT in the storage section 33 is accumulated in the storage section 33, the cover tape TT pushes open the lid member 34 and is automatically discharged (discharged) to the outside of the storage section 33.

[0048] When the cover tape TT in the storage section 33 pops out from the discharge opening 33K as described above, the worker pulls out the block of cover tape TT from the storage section 33 and cuts the cover tape TT to separate the block of cover tape TT from the cover tape TT in the storage section 33. Then, the worker manually operates the lid member 34 to position it in the closed position, closes the discharge opening 33K, and allows the tape feeder 16 to continue the component supply operation.

[0049] When an operator manually moves the lid member 34 from the open position to the closed position as described above, the elastic piece 34D of the lid member 34 swings about the swing shaft 35 in the opposite direction to the movement of the lid member 34 from the closed position to the open position via the intermediate open position, and the elastic deformation of the elastic piece 34D also follows the reverse process (Fig. 6(e) → Fig. 6(d) → Fig. 6(c) → Fig. 6(b) → Fig. 6(a)). Then, when the lid member 34 is in the closed position, the elastic piece 34D returns to its original position away from the abutment portion 43 (Fig. 6(a) and Fig. 4).

[0050] In the tape feeder 16 of the present embodiment, the cover member 34 is held in the closed position by the magnetic force of the magnet 41 and the magnetic body 42 attracting each other. For example, when the tape feeder 16 is transported, when the tape feeder 16 is attached to the feeder base 15a, or when the tape feeder 16 is removed from the feeder base 15a, if the main body 21 hits the body of an operator or a part of a component mounting device, the cover member 34 may open from the closed position due to the impact. However, in the tape feeder 16 of the present embodiment, even if the cover member 34 located in the closed position is swung in the opening direction due to the impact, it does not suddenly swung to the open position, but stops (holds its posture) once at an intermediate open position on the way. Therefore, even if the cover member 34 unintentionally opens from the closed position, the cover tape TT in the storage section 33 does not suddenly fly out to the outside.

[0051] As described above, in the tape feeder 16 of the present embodiment, the lid member 34 that opens and closes the discharge opening 33K of the cover tape TT connected to the storage section 33 can be stopped at a closed position that closes the discharge opening 33K, an open position that allows the cover tape TT in the storage section 33 to be discharged, and an intermediate open position between the closed position and the open position that opens the discharge opening 33K but does not allow the cover tape TT in the storage section 33 to be discharged. Therefore, even if the lid member 34 that opens and closes the storage section 33 for the cover tape TT opens unintentionally during transportation, etc., it is possible to prevent the cover tape TT in the storage section 33 from flying out of the discharge opening 33K.

[0052] Although the embodiment of the present invention has been described so far, the present invention is not limited to the above, and various modifications are possible. For example, in the above embodiment, the intermediate open position stopping means for stopping the lid member 34 at the intermediate open position was composed of the elastic piece 34D that swings around the swing shaft 35 integrally with the lid member 34, and the abutment part 43 provided on the main body part 21, but the intermediate open position stopping means may have other configurations as long as it can stop the lid member 34 at the intermediate open position between the closed position and the open position. [Industrial Applicability]
