The transmission lever 55 is urged clockwise by the spring 57 in FIG.

  60 is a U-shaped suppressor having a generally U-shaped cross section, and the carrier tape Cc after the storage tape C and the cover tape Ca are peeled is always pressed against the tape guide chute 59 so that they do not come off the tape feeder main body 7A. The tape feed hole Cd of the carrier tape Cc acts so as not to come off from the tape feed tooth 40A of the sprocket 40.

  The suppressor 60 is rotatably provided to the tape delivery device main body 7A via a rear pin 61, and a locking pin 62 provided at the front end portion of one side surface 60B is a lock device 63 of the tape delivery device main body 7A. The above-mentioned operation is ensured by engaging with the lock claw 64 of the (first lock device). The locking device 63 is biased in a direction in which one end is fixed to the lower part of the front end of the tape delivery device main body 7A and is made of a leaf spring and a coil spring is inserted into the pin 66 and opened. The lock claw 64 is connected to the support piece 65 through the pin 66 so as to be regulated.

  Further, a locking member 68 is integrally provided at the rear end portion of the suppressor 60, for example, and the locking pin 62 and the locking claw 64 are unlocked, and the suppressor 60 is rotated around the pin 61 as a fulcrum. In this case, the locking member 68 can be locked to the locking portion 69A of the lock member 69. The lock member 69 is made of a leaf spring and is formed in a counterclockwise spiral shape in FIG. 2, and its central portion is fixed to a mounting plate 67 provided on the upper part of the tape delivery device main body 7A, and has an outer end portion. On the contrary, the locking portion 69A is formed by rewinding clockwise. Although the locking member 68 is provided integrally with the suppressor 60, it may be formed as a separate member from the suppressor 60.

  Further, an opening is formed in the upper surface intermediate portion of the suppressor 60, and a shutter 70 is provided so as to be movable in the longitudinal direction of the suppressor 60 so as to cover the opening. That is, two guide pins 60A are erected on the suppressor 60, and the guide pins 60A are fitted on the heads of the guide pins 60A in a state where the guide pins 60A are fitted in elongated guide grooves 70C opened on the upper surface of the shutter 70. The guide plate 70D is fixed, and the shutter 70 can move in the longitudinal direction of the suppressor 60 while the guide groove 70C is guided to the guide pin 60A on the suppressor 60.

  Therefore, when the drive lever 33 is lowered, the shutter opening / closing pin 56 is fitted in the engagement groove 70B of the side piece 70A of the shutter 70, so that the transmission lever 55 is counterclockwise in FIG. The shutter 70 moves rearward by swinging to the right. By this movement, a component outlet 71 is formed, and the suction chip 13 can suck and take out the first chip component 4 in the component storage recess Cb of the carrier tape Cc.

  Further, the shutter 70 is formed with a slit 72 which becomes a fulcrum when the cover tape Ca is peeled off, and the peeled cover tape Ca passes from the lower side of the shutter 70 upward through the slit 72 and is folded back. Then, it is wound up by the cover tape winding device 31 via the guide rollers 75, 76, 77. The cover tape take-up device 31 is detachably attached to the attachment plate 67 and can be turned around a take-up reel 78 for taking up the cover tape Ca, and a support shaft 81 with one end via a pin 79. A swing lever 80 that is pivotably connected to the drive lever 33 and whose abutment portion 85 at the other end abuts against a stopper 86 to restrict the rotation, and a latching portion 82 of the swing lever 80. A ratchet lever 84 in which a tension spring 83 is stretched between a stop pin 87 and a ratchet gear (not shown) integrally formed with the take-up reel 78 and is pivotally supported by the ratchet lever 84. It consists of nails (not shown).

  Therefore, when the swing lever 80 is rotated clockwise in FIG. 2, the ratchet lever 84 is swung clockwise via the tension spring 83, the ratchet pawl is engaged with the ratchet gear, and the take-up reel 78 is The cover tape Ca, which is rotated clockwise by the angle and is affixed to the upper surface of the carrier tape Cc, is peeled off from the carrier tape Cc through the slit 72 of the suppressor 60 holding the storage tape C, and is taken up by the take-up reel 78. It will be wound up.

  The side surface 60B of the suppressor 60 on the opening end side of the slit 72 formed in the shutter 70 communicates with the opening end portion of the slit 72 and the component outlet 71, and the front and rear portions of the side surface 60B. A large opening 60C projecting downward, that is, a large opening 60C whose lower end position is lower than the lower end position of the front and rear side surfaces 60B, is opened, and the side surface 60B surrounds the opening 60C. In particular, the side surface 60B is also left below the opening 60C, and unlike the notch, the strength of the side surface 60B is maintained. When the cover tape Ca is passed through the slit 72 through the opening end of the slit 72 when the suppressor 60 is rotated about the pin 61 as a fulcrum and the storage tape C is loaded into the component supply device 7, After the end portion of the cover tape Ca is led out from the opening 60C to the outside of the component supply device 7 (see FIG. 9), the cover tape Ca is inserted into the slit 72 through the opening end portion and passed from below to above the shutter 70. The cover tape Ca is easily routed. Moreover, the length of the upper piece 70F on the front side of the upper piece 70E on the front side that forms the slit 72 is shortened by reducing the length of the slit 72 in the longitudinal direction (direction perpendicular to the conveying direction of the storage tape C). A person can easily pass the cover tape Ca through the slit 72 (see FIGS. 9 and 10). Further, the upper piece 70E and the upper piece 70F at the opening side end portion of the slit 72 are chamfered round in a plan view so that the cover tape Ca easily enters the slit 72A.

  The suppressor 60 and the shutter 70 hold the storage tape C against the tape guide chute 59 from above to guide intermittent feeding and form a component take-out port, covering the upper surface opening of the component storage portion Cb. The pressing member is provided with a slit for forming a fulcrum for peeling off, but a slit may be formed in the suppressor 60 without providing a shutter.

  The guide roller 75 is rotatable around a support shaft 75A, and an upper limit stopper 75B is fixed to the base end portion of the support shaft 75A (see FIG. 8). When the restrainer 60 is released and the suppressor 60 is rotated about the pin 61 as a fulcrum, the locking member 68 is locked to the locking portion 69A. Limit.

  As described above, the suppressor 60 always presses the carrier tape Cc after the storage tape C and the cover tape Ca are peeled against the tape guide chute 59, and the tape feed hole Cd of the carrier tape Cc from the tape feed teeth 40A of the sprocket 40. In the intermediate portion of the tape guide chute 59 along the transport direction of the storage tape C, a guide groove 88 is formed at a position substantially below the suppressor 60. Guide surfaces 59A and 59A of the tape guide chute 59 excluding 88 support and guide both end portions in the tape width direction of the carrier tape Cc after the storage tape C and the cover tape Ca are peeled off.

  Then, the carrier tape Cc immediately after the cover tape Ca is peeled off has a generally S-shape in which each end is folded back with the upper part 89A, the intermediate part 89B and the lower part 89C as pressing bodies that press the shutter 70 from below. The plate spring 89 is disposed in the guide groove 88 so that the open end of the upper portion 89A faces in the downstream direction, and the lower portion 89C of the plate spring 89 is fixed to the bottom surface 88A forming the guide groove 88 by the fixing screw 90. To do. The width of the leaf spring 89 is slightly smaller than the width of the guide groove 88.

  Since this leaf spring 89 presses the carrier tape Cc immediately after peeling the cover tape Ca against the shutter 70 from below, the gap between the carrier tape Cc and the shutter 70 is eliminated as much as possible even if the cover tape Ca is reduced in thickness. Since the space between the upper surface of the electronic component 4 stored in the component storage portion Cb and the shutter 70 can be made as small as possible, the carrier tape Cc is sufficiently pressed, the behavior of the minute electronic component 4 is stabilized, and the suction The adsorption rate by the nozzle 13 is improved. That is, conventionally, the cover tape Ca is peeled off from the carrier tape Cc to reduce the thickness of the cover tape Ca, so that a gap is formed between the carrier tape Ca and the shear 70, and the electronic component stored in the component storage portion Cb. The space between the upper surface of 4 and the shutter 70 becomes large, and the electronic component 4 accommodated in the carrier tape Cc is violated or standing by this space, so that the suction nozzle 13 cannot suck the electronic component 4 Alternatively, a suction error such as sucking the wrong surface of the electronic component 4 has occurred, leading to a reduction in the suction rate by the suction nozzle 13, but according to the present invention, the suction rate is improved.

  In addition, since the upper portion 89A that presses the carrier tape Cc is a flat plate spring 89, the carrier tape Cc is pressed from the lower side by the upper portion 89A so that there is almost no gap over the range of the upper portion 89A in the tape feeding direction. it can.

  The guide groove 88 formed in the tape guide chute 59 forms a space for disposing the leaf spring 89, but this space can also be used as a space for passing a component storage portion such as an embossed tape. .

  The operation will be described below with the above configuration. First, the tape delivery device 30 in the standby state is shown in FIGS. 2 and 3, and when it is driven in synchronization with the rotary table 12 in this state and the tape feed lift lever 32 is lowered, as shown in FIG. The drive lever 33 is also lowered, the transmission lever 55 rotates counterclockwise with the support shaft 53 as a fulcrum against the urging force of the spring 57, and the link lever 51 is moved to the right (front) to move the rocking body. 42 is rotated counterclockwise opposite to the tape feeding direction with the support shaft 41 as a fulcrum. Then, by the rotation of the rocking body 42, the feeding claw gets over by one mountain of the internal teeth of the sprocket 40.

  At this time, due to the counterclockwise rotation of the transmission lever 55, the shutter opening / closing pin 56 is fitted in the engagement groove 70B of the side piece 70A of the shutter 70, so that the shutter 70 moves rearward (FIG. 11). From the state to the state of FIG. By this movement, the component take-out port 71 is opened, and the leading chip component 4 in the component storage recess Cb of the carrier tape Cc can be sucked and taken out by the suction nozzle 13 (see FIGS. 6 and 12).

  Further, when the tape feed raising / lowering lever 32 is lowered as described above, the swing lever 80 is rotated clockwise in FIG. 5 to swing the ratchet lever 84 clockwise via the tension spring 83, and the ratchet pawl is moved to the ratchet. Since the gear is engaged with the gear, the take-up reel 78 is rotated clockwise by a predetermined angle, and the cover tape Ca attached to the upper surface of the carrier tape Cc is passed through the slit 72 of the suppressor 60 holding the storage tape C. Then, the tape is taken up on the take-up reel 78 while being peeled off from the carrier tape Cc.

  At this time, as shown in FIG. 13, since the leaf spring 89 presses the carrier tape Cc immediately after peeling the cover tape Ca against the shutter 70 from below, even if the cover tape Ca is thinned by peeling, the carrier tape Cc. And the gap between the shutters 70 can be eliminated. Therefore, in combination with the shutter 70, the carrier tape Cc is sufficiently pressed, the behavior of the minute electronic component 4 is stabilized, and the suction rate by the suction nozzle 13 is improved. Further, even if the flatness of the shutter 70 is not strict, the clearance between the carrier tape Cc and the shutter 70 can be eliminated even if there is a clearance in the component storage recess Cb of the carrier tape Cc that stores the electronic component 4. Therefore, as described above, the behavior of the minute electronic component 4 can be stabilized and the suction rate by the suction nozzle 13 can be improved.

  When the tape feed lift lever 32 is lifted, the drive lever 33 is also lifted by the urging force of the spring 57, the transmission lever 55 is rotated clockwise around the support shaft 53, and the link lever 51 is moved to the left (rear). The rocking body 42 is rotated clockwise around the support shaft 41 as a fulcrum. Then, by the clockwise rotation of the oscillating body 42, the feed claw meshing with the internal teeth of the sprocket 40 (more precisely, the grooves forming the teeth) causes the sprocket 40 to move in the carrier tape feeding direction (clockwise). Rotate.

  Accordingly, since the tape feed teeth 40A are fitted in the tape feed holes Cd of the carrier tape Cc, the carrier tape Cc is fed by one pitch. At this time, since the shutter opening / closing pin 56 is fitted in the engagement groove 70B of the side piece 70A of the shutter 70 by the clockwise rotation of the transmission lever 55, the shutter 70 moves forward, and the component outlet 71 Is closed (see FIG. 4). That is, the carrier tape Cc is fed by one pitch while the shutter 70 is closed (see FIG. 13).

  As described above, the peeling operation of the cover tape Ca and the feeding operation of the carrier tape Cc are performed, and the chip components 4 are sequentially taken out from the carrier tape Cc by the suction nozzle 13 and mounted on the printed circuit board 5. .

  Then, an operation of loading a new storage tape C into the component supply device 7 when a so-called component cut occurs due to the chip component 4 in the storage tape C being sent to the component extraction position and extracted. First, the component supply device 7 that has run out of the component is removed from the supply table 6 and moved onto the work table, the tape reel is removed from the component supply device 7, and a new tape reel around which the storage tape C is wound is attached to the component. The storage tape C is attached to the supply device 7 and fed out from the tape reel storing the new storage tape C by a certain length, and the new storage tape C is loaded into the component supply device 7 in the state of being laid on the work table. And set.

  That is, the operator presses the leaf spring support piece 65 upward with a finger to release the locking pin 62 and the locking claw 64 of the locking device 63 from being locked, and the suppressor 60 is counterclockwise with the pin 61 as a fulcrum. Rotate in the direction. When this operator lifts the suppressor 60 upward, the locking member 68 behind the pin 61, which is the rotation fulcrum, pivots counterclockwise and descends, contacting the locking portion 69A of the locking member 69, The lock member 69 made of a leaf spring is bent. And if it bends to some extent, the said locking member 68 will fit and lock to the locking part 69A.

  As described above, the operator opened the front end of the cover tape Ca peeled off from the carrier tape Cc on the side surface 60B of the suppressor 60 while maintaining the open state of the suppressor 60 as shown in FIG. As shown in FIG. 10, it is inserted into the slit 72 through the opening end of the slit 72 and passed through the shutter 70 from below to above through the large opening 60C. .

  Then, after releasing the hold of the suppressor 60 after the storage tape C is loaded into the component supply device 7, the operator may apply a load downward to the front end of the suppressor 60. When the suppressor 60 is rotated in the clockwise direction, the locking member 68 is also rotated and raised in the clockwise direction. Therefore, the locking member 69 made of a leaf spring is bent, and when it is bent to some extent, the locking member 68 is locked. The locking with the portion 69A is released. That is, when the operator operates the suppressor 60, the suppressor 60 can be held in an open state, and the held state can also be released.

  Then, holding the suppressor 60 in an open state is released, and the suppressor 60 is further lowered to engage the locking pin 62 and the locking claw 64 of the locking device 63. Thereafter, the component supply device 7 loaded with the new storage tape C is attached to the supply stand 6 so that the next chip component 4 can be mounted.

  The electronic component mounting apparatus has been described by taking a so-called high-speed chip mounter as an example. However, the electronic component mounting apparatus is not limited to this and may be applied to a multi-function chip mounter.

  In this embodiment, the leaf spring 89 is used as the pressing body. However, the present invention is not limited to this, and other pressing bodies may be used.
