However, for simplicity, only the vicinity of the upper end and the vicinity of the lower end of the cylinder 9 are shown. In FIG. 6, the cylinder 9 is provided with air supply / discharge ports 9io1, 9io2 at both ends in the longitudinal direction. A rail 9r extends inside the cylinder 9 along the longitudinal direction.

  A table that can be moved up and down in the directions of arrows A1 and A2 on the rail 9r by the action of the air driving force generated when the air supplied to the cylinder 9 from one of the air supply and discharge ports 9io1 and 9io2 is discharged from the other. 9t is arranged on the rail 9r. The table 9t is connected to the fixed bar 8f of the transport unit 8 by two screws 8fs1 and 8fs2. For this reason, the conveyance unit 8 is raised and lowered by raising and lowering the table 9t.

  Next, the effect | action which the cylinder 9 raises / lowers the rail 9r is demonstrated. One end of an air tube (not shown) is connected to each of the air supply / discharge ports 9io1 and 9io2. The other end of each air tube is connected to an air generating / discharging unit (not shown). The air generating and discharging unit can select a function of ejecting compressed air toward the air tube and a function of exhausting compressed air arriving from the air tube, for example, by a switching valve.

  In FIG. 6, the transport unit 8 is in the standby position P1 in the vicinity of the air supply / discharge port 9io1. From this state, the air generating / discharging part connected to the air supply / discharge port 9io1 located at the upper end of the cylinder 9 ejects compressed air toward the air tube and connects to the air supply / discharge port 9io2 located at the lower end of the cylinder 9 The generated air discharge section exhausts the compressed air coming from the air tube.

  At this time, compressed air is supplied from the air supply / discharge port 9io1 into the cylinder 9, flows in the cylinder 9 from the upper side to the lower side, and is discharged from the air supply / discharge port 9io2. As a result, the table 9t descends in the direction of the arrow A1. Along with this, the transport unit 8 also descends and stops at the lower end position P2 (see FIG. 11) near the air supply / discharge port 9io2. From this state, on the contrary, the air generating / discharging part connected to the air supply / discharge port 9io2 located at the lower end of the cylinder 9 ejects compressed air toward the air tube, and the air supply / discharge port 9io1 located at the upper end of the cylinder 9 The air generating / discharging unit connected to the air exhausts the compressed air coming from the air tube.

  In this case, compressed air is supplied from the air supply / discharge port 9io2 into the cylinder 9, flows in the cylinder 9 from the lower side to the upper side, and is exhausted from the air supply / discharge port 9io1. As a result, the table 9t rises in the direction of the arrow A2.

  Along with this, the transport unit 8 also rises and stops at the standby position near the air supply / discharge port 9io1 as in FIG. That is, one of the air generation / discharge portions (not shown) connected to the air supply / discharge ports 9io1, 9io2 by an air tube (not shown) ejects compressed air toward the air tube, and the other exhausts the compressed air coming from the air tube. Thus, the transport unit 8 moves up and down between the standby position and the lower end position. At that time, the transport unit 8 does not stop halfway. The air supply and discharge ports 9io1 and 9io2 are provided with adjusting screws 9io1a and 9io2a for adjusting the amount of compressed air supplied to the cylinder 9, respectively.

From this state, the second holding portion 103h2 rotates in the direction of arrow P around its center position in FIG. As a result, the first holding portion 103h1 and the empty reel R0 shown in FIG. 25 also rotate in the direction of arrow P around the center position in FIG. Next, the carrier tape T (FIG. 3B) containing the chip-type electronic component W is wound around the empty reel R0, and a carrier having a predetermined length is obtained by the action of the tape delivery cutting unit 104 shown in FIG. The tape T is fed to the empty reel R0 and then cut. Thereafter, a seal tape is prepared and applied to the winding end portion of the carrier tape T by the action of the seal tape preparation application unit 105 shown in FIG. Thus, the reel R around which the carrier tape T is wound is completed.

  When the reel R on which the carrier tape T has been wound is completed in the winding unit 103, the reel R is then removed from the winding unit 103 and stored in the stocker 107. The operation of the stocker 107 at this time will be described with reference to FIGS.

  In FIG. 7A, the reel R is placed on the reel receiving plate 7a of the stocker 7 in a state where the winding unit 103 completes winding the carrier tape T (FIG. 3B) onto the reel R. FIG. 6 is a front view showing a state where the transport unit 8 is at the standby position P1. FIG. 7B is a perspective view of FIG. In FIG. 7A, the description of the base 103b of the winding unit 103 is omitted. From this state, the first holding portion 103h1 retreats in the direction of arrow S2 in FIG. 18 by the action of the first cylinder 103c1. At the same time, the second holding portion 103h2 shown in FIG. 18 retreats in the direction of the arrow U2 by the action of a drive mechanism (not shown). Then, the fixing protrusion 103f fitted in the center hole Ra of the reel R also retracts in the direction of the arrow U2 together with the second holding plate 103h2, and comes out of the center hole Ra.

  As a result, the reel R is not supported by anything and falls in the direction of arrow B in FIGS. 7A and 7B due to the action of gravity. The dropped reel R is held in contact with the reel holding plates 8h1 and 8h2 (FIG. 5) and the guides 8a1 and 8a2 of the transport unit 8 located immediately below.

  This state is shown in FIGS. 8A, 8B, and 8C as a top view, a front view, and a side view. FIG. 9 shows an enlarged perspective view of the region N1 in FIG.

  Here, in FIGS. 8A, 8 </ b> B, and 8 </ b> C and the subsequent top view, front view, and side view of the same portion, the description of the base 103 b of the winding portion 103 is omitted for simplicity. In FIG. 9, only the transport unit 8 and the reel R are shown for the sake of simplicity. As shown in FIGS. 8 (a), (b), (c) and FIG. 9, in the dropped reel R, the two spaced apart parts at the lower part of the periphery abut against the inclined surfaces 8h1s, 8h2s at the upper part of the reel holding plates 8h1, 8h2. Are held individually. At the same time, two spaced apart lower portions of the first side plate Rs1 are in contact with the inclined surfaces 8a1s and 8a2s formed on the guides 8a1 and 8a2 and are held individually.

  By being held on the inclined surfaces 8a1s and 8a2s in this way, the reel R is inclined in the direction of the reel receiving plate 7a disposed at the lowermost part of the stocker 7, as shown in FIG. When the transport unit 8 receives the reel R from the winding unit 103, the transport unit 8 moves downward in the direction of the arrow A <b> 1 shown in FIG. 1 while holding the reel R by the action of the cylinder 9. This is shown in FIGS. 10 (a) and 10 (b) as a front view and a side view. The lowered transport unit 8 passes through the reel receiving plate 7a from top to bottom.

  The state at this time is shown in FIGS. 11A, 11B, and 11C as a top view, a front view, and a side view. FIG. 12 shows an enlarged perspective view of the region N2 in FIG.

  As described above, notches 7ac1 and 7ac2 are formed at the corners of both ends of the four sides of the reel receiving plate 7a on the side in contact with the back surface 7b. The notches have such a size that the guides 8a1 and 8a2 of the transport unit 8 and the reel holding plates 8h1 and 8h2 can pass in the vertical direction. For this reason, as shown in FIGS. 11 (a), 11 (b), and 11 (c) and FIG. 12, the transport unit 8 holding the reel R passes from the top to the bottom of the reel receiving plate 7a and directly below the reel receiving plate 7a. When the lower end position (P2) is reached, the guides 8a1, 8a2 and the reel holding plates 8h1, 8h2 of the transport unit 8 pass through the notches 7ac1, 7ac2. On the other hand, the reel R held by the guides 8a1 and 8a2 and the reel holding plates 8h1 and 8h2 comes into contact with the vicinity of the boundary line 7ax between the reel receiving plate 7a and the back surface 7b between the notches 7ac1 and 7ac2. The abutted reel R is separated from the guides 8a1 and 8a2 and the reel holding plates 8h1 and 8h2, and remains on the reel receiving plate 7a as it is. That is, when the transport unit 8 holding the reel R passes from the top to the bottom of the reel receiving plate 7a, only the transport unit 8 passes down, and the reel R is separated from the transport unit 8 and onto the reel receiving plate 7a. Remain.

  At this time, the reel R is held by the transport unit 8 and comes into contact with the vicinity of the boundary line 7ax. However, the reel R does not fall on the reel receiving plate 7a due to the action of gravity and does not come into contact with the vicinity of the boundary line 7ax. Therefore, there is almost no impact at the time of contact compared to the comparative example described later, and the reel R does not jump upward after contact. Therefore, it does not hold a posture that is unlikely to fall, such as being placed on the reel receiving plate 7a again in a state where the posture has changed after the reel R has jumped up and leaning against the back surface 7b of the stocker 7.

  By the way, when the reel R has already been placed on the reel receiving plate 7a, even if the next reel R abuts on the reel R, there is almost no impact at the time of abutment for the above-mentioned reason. The second side plate Rs2 (FIG. 2 (c)) of the reel R is not damaged. Further, the reel R has already been placed on the reel receiving plate 7a, and any one of the holes Rh5, Rh6, Rh7, Rh8 (FIG. 2C) of the reel R is located at the contact position. Even in this case, there is almost no impact at the time of contact for the reason described above. For this reason, the lower end of the reel R that comes into contact with any one of the holes Rh5, Rh6, Rh7, and Rh8 of the reel R that has already been placed on the reel receiving plate 7a is fitted into the reel R, and the posture of the reel R is substantially vertical as it is. Never become.

  Further, as described above, since the reel R is held by the transport unit 8 in a posture inclined in the direction of the reel receiving plate 7a, the reel R remaining on the reel receiving plate 7a can be more reliably secured by the action of gravity. It falls in the direction of arrow C in FIG.

  For this reason, according to this Embodiment, the extrusion board 103p (FIG. 17) described by the comparative example mentioned later becomes unnecessary. Further, when the reel R remaining on the reel receiving plate 7a falls down and is placed on the reel R already placed on the reel receiving plate 7a, it is placed on the reel receiving plate 7a first. On the second side plate Rs2 of the reel R, the first side plate Rs1 of the reel R remaining on the reel receiving plate 7a is inclined and comes into contact. For this reason, almost no impact is generated on both the reels R at the time of contact, and in this case, the reels are not damaged.

  Next, the transport unit 8 that has passed from the top to the bottom of the reel receiving plate 7a stops at the lower end position. This state is shown in FIGS. 13A, 13B, and 13C as a top view, a front view, and a side view. As described above, the reel R is reliably tilted in the direction of the arrow C in FIG. 11C and FIG. 12, and is placed on the reel receiving plate 7a with the second side plate Rs2 facing upward. Next, the transport unit 8 stopped at the lower end position rises in the direction of arrow A2 shown in FIG. Also at this time, since the guides 8a1 and 8a2 and the reel holding plates 8h1 and 8h2 pass through the notches 7ac1 and 7ac2 formed in the reel receiving plate 7a, the transport unit 8 is mounted on the reel receiving plate 7a and the reel receiving plate 7a. It passes from the bottom to the top without contacting the reel R placed. Therefore, the reel R is not damaged even when the transport unit 8 is raised.

  Next, the transport unit 8 returns to the standby position and stops as shown in FIGS. 14A, 14B, and 14C as a top view, a front view, and a side view. The transport unit 8 stands by at this position, and during that time, the next empty reel R0 is supplied from the empty reel stock unit 102 and held in the winding unit 103 shown in FIG. 1, and is shown in FIG. 3 (b). The carrier tape T is wound on the reel R. Then, according to the above-described procedure, the transport unit 8 receives and holds the reel R from which the carrier tape T has been wound up from the winding unit 103. This is repeated in the same manner.

  As a result of this repetition, each time one reel R is placed on the reel receiving plate 7a in FIG. 1, the position of the uppermost reel R placed is substantially equivalent to the thickness of one reel R. Ascend by distance. For this reason, it is necessary to stop the operation of the carrier tape take-up and storage device 1 when the number of reels R placed on the reel receiving plate 7a reaches a predetermined quantity and notify the operator. The procedure will be described below.

  FIG. 15A shows a side view of a state in which a predetermined number of reels R are placed on the reel receiving plate 7a. A perspective view is shown in FIG.

  In FIG. 15A, the uppermost reel R among the reels R placed on the reel receiving plate 17a overlaps with the position of the opening 7rso of the reel sensor light source 7rs. On the other hand, FIGS. 8 (c), 10 (b), 11 (c), and 13 (c) showing a case where the number of reels R placed on the reel receiving plate 7a is less than a predetermined number. In FIG. 14C and the like, there is nothing that blocks the opening 7rso of the reel sensor light source 7rs. That is, when the reel R blocks the opening 7rso of the reel sensor light source 7rs, the reel sensor 7r shown in FIG. 4B detects it.

  In other words, the reel sensor 7r detects that the reel R placed on the reel receiving plate 7a has reached a predetermined quantity, that is, the reel R stored in the stocker 7 has reached a predetermined quantity. To do. In this state, the carrier tape take-up and storage device 1 (FIG. 1) stops its operation and notifies the operator by sounding a buzzer or lighting a lamp.

  Next, the operator carries out the reel R from the stocker 7 of the carrier tape take-up and storage device 1. As a result, the reel R is not placed on the reel receiving plate 7a. Then, the carrier tape take-up and storage device 1 is restarted. The restarting method is, for example, by pressing a push button switch (not shown).

  The reel R (FIGS. 2A, 2B, and 2C) that has wound the carrier tape T (FIG. 3B) in the winding unit 103 shown in FIG. It is mounted on the receiving plate 7a.

  As described above, according to the present embodiment, the reel R around which the carrier tape T is wound can be safely placed on the reel receiving plate without being damaged.

Comparative Example Next, a carrier tape take-up and storage device 101 as a comparative example will be described. The stocker 107 of the carrier tape take-up and storage device 101 is disposed immediately below the take-up unit 103 in FIG. A motor 107m is disposed at the lowermost part of the stocker 107, and a reel receiving plate 107a that is moved up and down in the directions of arrows A1 and A2 by driving of the motor 107m is provided. As will be described later, the reel receiving plate 107a is formed with an acute angle upward with respect to its lifting path. The front surface of the reel receiving plate 107a is open, and the remaining three sides are surrounded by a left side surface 107s1, a right side surface 107s2, and a back surface 107b, respectively. Two elongated openings 107o1 and 107o2 are formed in the back surface 107b in the vertical direction. On the uppermost portion of the stocker 107, a placement sensor light source 107ps is disposed on the left side surface 107s1, and a placement sensor detection unit 107pd is disposed on the right side surface 107s2 facing the placement sensor light source 107ps. Further, on the left side surface 107s1, an upper limit sensor detection unit 107ud is disposed at a position slightly below the placement sensor light source 107ps, and an upper limit sensor light source 107us is disposed on the right side surface 107s2 facing the upper limit sensor detection unit 107ud. A full load sensor 107f is disposed on the left side surface 107s1 at the bottom of the stocker 107.

  Details of the stocker 107 as a comparative example are shown in FIGS. 19A, 19B, and 19C as a top view, a front view, and a side view. Here, the reel receiving plate 107a is in a state of being in its upper limit position. Further, the side view of FIG. 19C is a perspective view in which the right side surface 107s2 in FIG. 17 is omitted. Here, the side view quoted below is a perspective view in which the right side surface 107s2 in FIG. 17 is omitted unless otherwise specified. Further, FIG. 20A is an enlarged view of the region E in FIG. 19A, FIG. 20B is an enlarged view of the region F in FIG. 19B, and J of region G in FIG. An enlarged view taken in the direction of the arrow is shown in FIG. Further, FIG. 20D shows an enlarged view of the region G in FIG.

  As shown in FIGS. 19A and 19C and FIGS. 20A and 20C, a circular rotatable roller 107r is disposed in the vicinity of the upper end of the back surface 107b. The periphery of the roller 107r is formed smoothly, and a chain 107c is hung around the roller 107r as shown in FIGS. 19 (c) and 20 (c). And as shown in FIG.19 (c), the chain 107c is hung on the periphery of the gearwheel 107g fitted to the rotating shaft of the motor 107m arrange | positioned in the lower end vicinity of the back surface 107b. The pitch of the chain 107c and the pitch of the gear 107g are the same, and the chain 107c is fitted to the gear 107g. For this reason, when the motor 107m rotates in both directions, the chain 107c moves up and down between the gear 107g and the roller 107r.

  By the movement of the chain 107c, the reel receiving plate 107a moves up and down in the directions of arrows A1 and A2 shown in FIG. The reel receiving plate 107a is arranged at an acute angle α upward with respect to the arrows A1 and A2 which are the moving direction of the chain, that is, the up and down direction. Further, as shown in FIGS. 19B, 19C, 20B, and 20D, the lower surface of the reel receiving plate 107a is substantially parallel to the left side surface 107s1 and the right side surface 107s2 on one side close to the left side surface 107s1. A detection plate 107d having a parallel plane protrudes vertically downward from the lower surface.

  Here, a mechanism for raising and lowering the reel receiving plate 107a as a comparative example will be described. As shown in FIGS. 19B, 19C and 20B, 20D, a vertical surface 107av formed integrally with the reel receiving plate 107a by bending is continuous below the reel receiving plate 107a. As shown in FIGS. 20A and 20D, the vertical surface 107av is fixed to a rectangular conveyance fixing surface 107tf on the back surface 107b side. Further, both left and right ends of the conveyance fixing surface 107tf are bent at substantially right angles to form a first conveyance surface 107t1 and a second conveyance surface 107t2, respectively.

  As shown in FIGS. 20A and 20C, the first transport surface 107t1 and the second transport surface 107t2 respectively penetrate the opening 107o1 and the opening 107o2 and project outside the back surface 107b. The outside of the back surface 107b is a space between the base 103b of the winding unit 103 and the back surface 107b of the stocker 107 shown in FIG. 17, but FIGS. 19 (a), (b), (c) and the following. In the top view, front view, and side view of the same portion, the base 103b is omitted for simplicity.

  As shown in FIG. 20A, the chain 107c is located between the first transport surface 107t1 and the second transport surface 107t2 outside the back surface 107b. Here, for simplicity, the chain 107c in FIG. 20A shows only a horizontal cross section. The U-shaped connecting body 107j connected to the first transport surface 107t1 is connected to the chain 107c, so that the reel receiving plate 107a and the chain 107c are integrated. Here, as shown in FIG. 20C, the connecting body 107j is connected to the first transport surface 107t1 by screws 107s1 and 107s2, and is connected to the chain 107c by screws 107s3 and 107s4.

  In FIG. 20C, a first wheel 107w1 is attached near the upper end of the first transport surface 107t1, and a second wheel 107w2 is attached near the lower end. Similarly, a third wheel 107w3 is attached near the upper end of the second transport surface 107t2, and a fourth wheel 107w4 is attached near the lower end.

  FIG. 20D shows a third wheel 107w3 and a fourth wheel 107w4 attached to the second transport surface 107t2 among these four wheels. The third wheel 107w3 and the fourth wheel 107w4 are both formed in a cylindrical shape, and both the center side fixing portions 107w3f and 107w4f are fixed to the second transport surface 107t2. The outer peripheral side rotation portions 107w3r and 107w4r are rotatable around the fixed portions 107w3f and 107w4f, respectively. These rotating portions 107w3r and 107w4r are in contact with the outer surface of the back surface 107b. The structures of the first wheel 107w1 and the second wheel 107w2 are the same.

  As described above, the U-shaped connection body 107j connected to the first transport surface 107t1 is connected to the chain 107c. In addition, a conveyance fixing surface 107tf molded integrally with the first conveyance surface 107t1 is fixed to a vertical surface 107av molded integrally with the reel receiving plate 107a. Therefore, when the chain 107c moves up and down by the rotation of the motor 107m shown in FIG. 19C, the first wheel 107w1, the second wheel 107w2, the third wheel 107w3, and the fourth wheel 107w4 The reel receiving plate 107a is smoothly raised and lowered while simultaneously rotating while being in contact with the outer surface of the reel.

  Next, the configuration and operation of the sensor near the upper limit position of the reel receiving plate 107a will be described with reference to FIGS. In FIG. 20B, a placement sensor 107p is configured by the placement sensor light source 107ps disposed on the left side plate 107s1 and the placement sensor detection unit 107pd disposed on the right side plate 107s2. Here, the placement sensor light source 107 ps and the placement sensor detection unit 107 pd are arranged at opposing positions, and the placement sensor detection unit 107 pd detects light emitted from the placement sensor light source 107 ps. If there is an object between the two, light is blocked by the object, so the placement sensor detection unit 107pd does not detect the light. This detects that there is an object in between. Similarly, the upper limit sensor 107u is configured by the upper limit sensor light source 107us disposed on the right side plate 107s2 and the upper limit sensor detection unit 107ud disposed on the left side plate 107s1.

  The functions of the upper limit sensor light source 107us and the upper limit sensor detection unit 107ud are the same as those of the placement sensor light source 107ps and the placement sensor detection unit 107pd, respectively, and that there is an object between the upper limit sensor light source 107us and the upper limit sensor detection unit 107ud. To detect.

  Note that, in the placement sensor 107p and the upper limit sensor 107u, the arrangement of the light source and the detection unit is reversed left and right. This is because the arrangement positions of these two sensors 107p and 107u are very close to each other, and if the arrangement of the light source and the detection unit is the same on both the sensors 107p and 107u, the placement sensor detection unit 107pd becomes the upper limit sensor light source. This is because there is a possibility that light emitted from 107 us may be erroneously detected, and conversely, the upper limit sensor detection unit 107ud may erroneously detect light emitted from the placement sensor light source 107ps.

  Next, the positional relationship between the placement sensor 107p and the upper limit sensor 107u and the reel receiving plate 107a in FIG. 20B will be described with reference to FIG. In FIG. 20D, the reel receiving plate 107a is at the upper limit position and overlaps the position of the opening 107i of the upper limit sensor detection unit 107ud disposed on the left side surface 107s1.

  The opening 107i has the same shape as the opening (not shown) of the upper limit sensor light source 107us (FIG. 20B) disposed on the right side surface 107s2 (FIG. 20B), and is in an opposing position. For this reason, the light emitted from the opening (not shown) of the upper limit sensor light source 107us (FIG. 20B) is blocked by the reel receiving plate 107a and does not reach the opening 107i of the upper limit sensor detection unit 107ud. Thereby, the upper limit sensor 107u (FIG. 20B) detects that the reel receiving plate 107a is at the upper limit position.

  In FIG. 20D, the placement sensor light source 107ps is disposed on the left side surface 107s1 at a position directly above the upper limit sensor detection unit 107ud. Since the reel R (FIGS. 2A, 2B, and 2C) is not placed on the reel receiving plate 107a, there is no object that blocks the opening 107o of the placement sensor light source 107ps. The opening 107o has the same shape as the opening (not shown) of the mounting sensor detection unit 107pd (FIG. 20B) disposed on the right side surface 107s2 (FIG. 20B), and is at the opposite position. . For this reason, the light emitted from the opening 107o of the mounting sensor light source 107ps reaches the opening (not shown) of the mounting sensor detection unit 107pd (FIG. 20B) without being blocked. Thereby, the placement sensor 107p (FIG. 20B) detects that the reel R (FIGS. 2A, 2B, and 2C) is not placed on the reel receiving plate 107a.

  Next, the operation of the comparative example will be described. FIG. 26A shows the reel receiving plate 107a of the stocker 107 in the upper limit position in a state where the winding unit 103 completes winding the carrier tape T (FIG. 3B) onto the reel R, and the reel receiving plate It is a front view which shows the state in which the reel R is not mounted on the board 107a. FIG. 26B is an enlarged perspective view of a region K in FIG. Here, the X direction arrow view of FIG. 26A shows that the empty reel R0 in FIG. 25 is the reel R that has completed the winding of the carrier tape T.

  In FIG. 26A, the description of the base 103b of the winding unit 103 is omitted. From this state, the first holding portion 103h1 retreats in the arrow S2 direction shown in FIG. 18 by the action of the first cylinder 103c1. At the same time, the second holding portion 103h2 shown in FIG. 18 retreats in the direction of the arrow U2 by the action of a drive mechanism (not shown). Then, the fixing protrusion 103f fitted in the center hole Ra of the reel R also retracts in the direction of the arrow U2 together with the second holding plate 103h2, and comes out of the center hole Ra. As a result, the reel R is not supported by anything, and falls in the direction of arrow B shown in FIGS. 26 (a) and 26 (b) by the action of gravity. The dropped reel R comes into contact with the reel receiving plate 107a located immediately below in an upright state. This state is shown in FIGS. 27A, 27B, and 27C as a top view, a front view, and a side view. FIG. 28 shows an enlarged perspective view of the region M1 in FIG. In FIG. 28, for the sake of simplicity, the description of the winding unit 103 other than the reel stopper 103 s and its surroundings is omitted.

  As shown in FIGS. 26 (b) and 27 (c), the reel R that has fallen contacts the reel contact position 107ap near the back surface 107b on the reel receiving plate 107a. And it falls in the direction of arrow C shown in FIG.27 (c) and FIG. 28, and is mounted on the reel receiving plate 107a.

  In FIG. 26B, the diameter of the reel R is D, and in FIG. 26B, the height difference between the lower side 103e1 of the first guide plate 103g1 and the reel contact position 107ap is H. At this time, when D ≧ H, when the reel R dropped in the arrow B direction comes into contact with the reel contact position 107ap, the vicinity of the upper end of the reel R is the first guide plate 103g1 and the second guide plate. It will be in the state inserted between 103g2. In that case, the reel R cannot fall down in the direction of arrow C in FIGS. For this reason, in FIG. 26B, there is a relationship of D <H between the diameter D of the reel R and the height difference H between the lower side 103e1 of the first guide plate 103g1 and the reel contact position 107ap. The length of H is set so as to hold.

  Further, in order to assist the operation in which the reel R tilts in the direction of the arrow C from the state of FIG. 27C, the reel stopper 103s and the push plate 103p are operated in the direction of the arrow V1 shown in FIG. To advance to. At this time, the reel R falls in the direction of arrow C by being pushed by the pushing plate 103p. Since the reel stopper 103s and the pushing plate 103p are stopped at the position shown in FIG. 25, the next empty reel R0 is supplied from the empty reel stock portion 102 shown in FIG. And hold. The winding unit 103 winds the carrier tape T shown in FIG. 3B on the empty reel R0. Note that the carrier tape T is sent out toward the winding unit 103 after the winding unit 103 completes winding of the carrier tape T until the next empty reel R0 is held in the winding unit 103. ing. For this reason, due to the action of the tape stock unit 106 shown in FIG. 17, the reel R that has completed the winding of the carrier tape is removed from the winding unit 103 and flows until the next empty reel R0 is held in the winding unit 103. Accumulate the incoming carrier tape.

  27 (c) and 28, when the reel R falls down in the direction of arrow C, the reel R is placed on the reel receiving plate 107a. This state is shown in FIGS. 29A, 29B, and 29C as a top view, a front view, and a side view. As described above, in the empty reel R0 supplied to the winding unit 103 in FIG. 23, the first side plate Rs1 (FIG. 2B) faces the first guide plate 103g1 side. For this reason, in FIG. 28, the first side plate Rs1 is positioned on the reel receiving plate 107a side.

  In FIG. 27C and FIG. 28, when the reel R falls down in the direction of arrow C, it is placed on the reel receiving plate 107a with the second side plate Rs2 (FIG. 2C) facing up. FIG. 30 shows an enlarged view of the region M2 in FIG. In FIG. 30, the reel receiving plate 107a is at the upper limit position as in FIG. And it overlaps with the position of the opening 107i of the upper limit sensor detection unit 107ud arranged on the left side surface 107s1. Thus, as in FIG. 20D, the upper limit sensor 107u (FIG. 20B) detects that the reel receiving plate 107a is at the upper limit position.

  In FIG. 30, the reel R is placed on the reel receiving plate 107a and overlaps the position of the opening 107o of the placement sensor light source 107ps. As a result, the light emitted from the opening 107o of the placement sensor light source 107ps is blocked and does not reach the opening (not shown) of the placement sensor detection unit 107pd (FIG. 20B). Thereby, the placement sensor 107p (FIG. 20B) detects that the reel R is placed on the reel receiving plate 107a.

  Thus, when both the upper limit sensor 107u (FIG. 20B) and the placement sensor 107p (FIG. 20B) detect an object that blocks light, the motor 107m shown in FIG. 29C rotates. The chain 107c moves through the gear 107g so as to lower the reel receiving plate 107a in the direction of the arrow A1 shown in FIG. 30 until the mounting sensor 107p (FIG. 20B) no longer detects an object that blocks light, that is, until the opening 107o of the mounting sensor light source 107ps does not overlap the position of the reel R. The receiving plate 107a is lowered. Then, the motor 107m (FIG. 29 (c)) is stopped, and thereby the reel receiving plate 107a is also stopped. This state is shown in FIGS. 31A, 31B, and 31C as a top view, a front view, and a side view. FIG. 32 shows an enlarged view of the region M3 in FIG. 31 (b) and 31 (c) are shown with an arrow A1 indicating that the reel receiving plate 107a has been lowered until the state shown in FIGS.

  In FIG. 32, the reel R first placed on the reel receiving plate 107a overlaps the position of the opening 107i of the upper limit sensor detection unit 107ud disposed on the left side surface 107s1. For this reason, light emitted from the opening (not shown) of the upper limit sensor light source 107us (FIG. 20B) is blocked by the reel R and does not reach the opening 107i of the upper limit sensor detection unit 107ud. Thereby, the upper limit sensor 107u (FIG. 20B) detects the presence of the reel R. Since nothing is placed on the reel R, there is no object blocking the opening 107o of the placement sensor light source 107ps. For this reason, the light emitted from the opening 107o of the mounting sensor light source 107ps reaches the opening (not shown) of the mounting sensor detection unit 107pd (FIG. 20B) without being blocked. At this time, the placement sensor 107p (FIG. 20B) detects that nothing is placed on the reel R.

  The reel receiving plate 107a stands by at this position, and during that time, the next empty reel R0 is supplied from the empty reel stock part 102 and held in the winding part 103 shown in FIG. 17, and the carrier shown in FIG. Tape T is wound on reel R. Then, the reel R that has completed the winding of the carrier tape T is placed on the reel R shown in FIG. 32 according to the above-described procedure and overlaps the position of the opening 107o. Then, the reel receiving plate 107a is lowered and stopped until the opening 107o does not overlap the position of the newly placed reel R. This is repeated in the same manner.

  As a result of this repetition, every time one reel R is placed on the reel receiving plate 107a in FIG. 17, the reel receiving plate 107a is lowered by a distance corresponding to the thickness of one reel R in general. For this reason, it is necessary to stop the operation of the carrier tape take-up and storage device 101 when the number of reels R placed on the reel receiving plate 107a reaches a predetermined quantity and notify the operator. The procedure will be described below. FIGS. 33A, 33B, and 33C show a state where a predetermined number of reels R are placed on the reel receiving plate 107a as a top view, a front view, and a side view. A perspective view is shown in FIG.

  33 (a), (b), (c) and FIG. 34, the reel receiving plate 107a is at the lower limit position, and this state is detected by the full load sensor 107f as will be described later. Further, among the reels R placed on the reel receiving plate 107a, the uppermost reel R overlaps with the position of the opening 107o of the placement sensor light source 107ps, like the reel R in FIG. Here, an enlarged view of the region Q in FIG. 33C is shown in FIG.

  FIG. 35 (a) is different from FIG. 35 (b) in that another reel R is placed on the reel receiving plate 107a, and the reel receiving plate 107a is moved by the action of the motor 107m shown in FIG. 33 (c). It shows a state where the lower limit position is reached when descending. That is, when the reel R is placed on the reel receiving plate 107a from the state of FIG. 35A and the reel receiving plate 107a is lowered in the direction of the arrow A1 shown in FIG. 31, the state of FIG. .

  In FIG. 35A, the front surface of the detection window 107fw of the full load sensor 107f is open. Inside the detection window 107 fw, there is a light source (not shown) for sending light toward the outside of the detection window 107 fw, and the light sent from the light source is reflected by an object existing outside the detection window 107 fw to detect the detection window A detector (not shown) for detecting the incident from 107 fw is arranged. In FIG. 35A, since the front surface of the detection window 107fw is open as described above, the detector does not detect light. On the other hand, in FIG. 35B, the detection plate 107d protruding from the lower surface of the reel receiving plate 107a covers the front surface of the detection window 107fw. At this time, the light emitted outside from the light source through the detection window 107fw is reflected by the detection plate 107d and again detected by the internal detector through the detection window 107fw. That is, the full load sensor 107f detects that the reel receiving plate 107a is at the lower limit position when the state shown in FIG.

  In this case, as described above, in FIG. 33 (c), as in FIG. 30, the position of the opening 107o of the placement sensor light source 107ps and the top of the reels R placed on the reel receiving plate 107a. The positions of the reels R are the same. Therefore, the placement sensor 107p in FIG. 20B detects that the reel R is placed. That is, as shown in FIG. 35B, the full load sensor 107f detects that the reel receiving plate 107a is at the lower limit position. In addition, as shown in FIG. 30, when the placement sensor 107p (FIG. 20B) detects that the reel R is placed on the reel receiving plate 107a, the reel R stored in the stocker 107 is defined in advance. The quantity has been reached.

  In this state, the carrier tape take-up and storage device 101 (FIG. 17) stops its operation and notifies the operator by sounding a buzzer or turning on a lamp. The operator carries out the reel R from the stocker 107 of the carrier tape take-up and storage device 101. As a result, the reel R is not placed on the reel receiving plate 107a. Then, the carrier tape take-up and storage device 101 is restarted. The restarting method is, for example, by pressing a push button switch (not shown).

  As a result of the re-startup, the reel receiving plate 107a on which the reel R is not placed is raised in the direction of arrow A2 by the action of the motor 107m as shown in FIGS. 36 (a), (b), and (c). And it returns to the same upper limit position as Fig.19 (a), (b), and (c), and stops. From this state, the reel R (FIGS. 2A, 2B, and 2C) on which the carrier tape T (FIG. 3B) is wound in the winding unit 103 shown in FIG. It is placed on the plate 107a.

  Incidentally, the carrier tape take-up and storage device 101 in such a comparative example has the following problems. As described above, in FIG. 26B, after the reel R falls in the direction of the arrow B and comes into contact with the reel receiving plate 107a, it can be tilted in the direction of the arrow C shown in FIG. 26 (b), the relationship of D <H is established between the diameter D of the reel R and the height difference H between the lower side 103e1 of the first guide plate 103g1 and the reel contact position 107ap. The length of H is set so that.

  Here, the diameter D of the reel R is determined based on the standard, and is 18 cm at the minimum. That is, in FIG. 26B, the distance that the reel R falls from the winding unit 103 to the reel receiving plate 107a is greater than 18 cm. In the state where the reel R is already placed on the reel receiving plate 107a, when the next reel R falls on the reel R at the uppermost position, the next reel R falls a distance of 18 cm or more. Will do. At this time, the arc-shaped lower end of the dropped reel R comes into contact with the upper surface of the reel R at the uppermost position, that is, the second side plate Rs2 (FIG. 2C). For this reason, the impact caused by the acceleration at the time of dropping may be concentrated on one point of contact, and the second side plate Rs2 may be damaged.

  In order to prevent this damage, it is conceivable that when the reel R is dropped, the position of the reel receiving plate 107a is further raised so as to shorten the drop distance and reduce the impact at the time of contact. However, by doing so, a relationship of D> H is established between the diameter D of the reel R and the height difference H between the lower side 103e1 of the first guide plate 103g1 and the reel contact position 107ap. Become. In this case, as described above, the reel R falls on the reel receiving plate 107a and maintains a substantially vertical posture, and the vicinity of the upper end of the reel R is the first guide plate 103g1 and the second guide plate 103g2. It will be in the state inserted between.

  In this case, as described above, in this state, the reel R cannot fall in the direction of the arrow C shown in FIG. Therefore, after the reel R falls on the reel receiving plate 107a, the reel receiving plate 107a is lowered in the direction of the arrow A1 in FIG. 17 by the action of the motor 107m shown in FIG. Stop at a position where the relationship is D <H. Then, the vicinity of the upper end of the reel R is pulled out from between the first guide plate 103g1 and the second guide plate 103g2, and is separated downward from the winding portion 103, as shown in FIGS. 27 (a), (b), and (c). It becomes a state. In this state, the reel R can fall in the direction of the arrow C. However, in this case, it takes time for the reel R to drop from the winding unit 103 in the state of FIG. 26B to reach a position separated from the winding unit 103, that is, the state of FIG. 27C. . Until this time elapses, the next empty reel R0 is supplied from the empty reel stock portion 102 shown in FIG. 17 to the take-up portion 103 and held, and the carrier tape T (FIG. 3B) is wound around the reel R. Unable to start taking work. That is, the processing speed decreases.

  In FIGS. 27 (a), (b), and (c), when the reel R falls and comes into contact with the reel receiving plate 107a, it is normal that the reel R immediately falls in the direction of arrow C in FIG. 27 (c). However, this may not be the case. Such a case will be described with reference to FIGS.

  37 (a) and 37 (b) are enlarged views of the region M1 in FIG. 27 (c). Unlike FIG. 27 (c), FIGS. 37A and 37B are explanatory diagrams when the reel R does not fall in the direction of arrow C. In FIG. 37A, the reel R is not placed on the reel receiving plate 107a. Then, the reel R falls from the winding unit 103 (FIGS. 26A and 26B) and comes into contact with the reel receiving plate 107a at the contact position 107ap. At this time, due to the impact at the time of contact, the reel R may jump upward at the contact position 107ap and be slightly separated from the reel receiving plate 107a. It tilts to the side of 107b and is mounted again on the reel receiving plate 107a (FIG. 37 (b)).

  At this time, the reel R forms an angle β with the extrusion plate 103p on the reel receiving plate 107a and is stable in a posture leaning on the extrusion plate 103p, and does not fall in the direction of the arrow C shown in FIG. .

  In FIGS. 37 (a) and 37 (b), it has been described that the reel R is not placed on the reel receiving plate 107a. However, the reel R is placed on the reel receiving plate 107a, and the uppermost thereof. A similar situation may occur when the next reel R falls on the reel R at the position. This state will be described below.

  As described above, the reel R placed on the reel receiving plate 107a has the second side plate Rs2 facing upward, as shown in FIG. 29A, for example. That is, the four holes Rh5, Rh6, Rh7, and Rh8 shown in FIG.

  However, when the loaded reel R is viewed from above, the positions of these holes Rh5, Rh6, Rh7, Rh8 are different for each reel R. That is, in the state where the reel R is already placed on the reel receiving plate 107a, when the next reel R falls on the reel R at the uppermost position, the reel at the uppermost position is at the drop position. It is completely random whether a portion of R other than the holes Rh5, Rh6, Rh7, Rh8 is located, or any of the holes Rh5, Rh6, Rh7, Rh8 is located.

  Among these, when a portion other than the holes Rh5, Rh6, Rh7, Rh8 of the reel R at the uppermost position is located at the dropping position, the state can be the same as in FIGS. When any of the holes Rh5, Rh6, Rh7, Rh8 of the reel R at the uppermost position is located at the dropping position, the lower end of the reel R that has been dropped due to the impact at the time of dropping is fitted into the hole, It may be a posture that stands almost as it is. Also in this case, the dropped reel R remains stable in its posture and does not fall in the direction of arrow C shown in FIG.

  When the reel R that has fallen on the reel receiving plate 107a as described above is stabilized in a posture that does not fall in the direction of the arrow C shown in FIG. 103p is arranged (see FIG. 17). That is, in the winding unit 103, when the reel stopper 103s advances in the direction of the arrow V1 in preparation for the fall of the empty reel R0 as shown in FIG. 22, the pushing plate 103p integrated with the reel stopper 103s is also in the direction of the arrow V1. Advance. As a result, the reel R0, which is stable in a posture leaning against the pushing plate 103p as shown in FIG. 37B, is tilted in the direction of arrow C in FIG.

  Similarly, as described above, the lower end of the dropped reel R is fitted into any one of the holes Rh5, Rh6, Rh7, and Rh8 of the reel R at the uppermost position of the reel receiving plate 107a, and the posture is standing substantially as it is. Even in this case, the reel R that has been in a substantially vertical posture is tilted in the direction of arrow C in FIG. 27C by the push-out plate 103p that advances in the direction of arrow V1 in FIG. In this way, the reel R in a posture that does not fall in the direction of arrow C in FIG. 27C on the reel receiving plate 107a is forcibly tilted by the action of the push plate 103p.

  By the way, the weight of the reel R varies depending on the material of the carrier tape T shown in FIG. 3 and the weight of the chip-type electronic component W housed in the recess Tc. In addition, there are subtle irregularities on the lower end of the reel R or the surface of the reel receiving plate 107a that abuts at the abutting position 108ap in FIG. Therefore, depending on the weight of the falling reel R and which part of the lower end of the falling reel R abuts on which part on the reel receiving plate 107a, when the reel R jumps from the state of FIG. There are various angles, directions, and heights.

  Accordingly, the angle β formed by the reel R and the extrusion plate 103p in FIG. 37B also varies. When β becomes larger than a certain level, the reel R cannot be tilted in the direction of the arrow C (FIG. 27C) by the pushing plate 103p. In that case, since the reel R is not placed on the reel receiving plate 107a as shown in FIG. 30, the placement sensor 107p shown in FIG. 20B cannot detect the reel R.

  For this reason, the reel receiving plate 107a does not descend in the direction of the arrow A1 shown in FIGS. Then, after the winding unit 103 shown in FIG. 26 (b) holds the next empty reel R0 (FIG. 25) vertically and winds the carrier tape T (FIG. 3 (b)) in that state. Then, it is dropped as the next reel R on the reel receiving plate 107a maintaining the state of FIG.

  When such a situation continues, the reel receiving plate 107a remains stopped, and the reel R in the posture of FIG. 37 (b) continues to increase on the reel receiving plate 107a. In order to prevent this, it is necessary to add a sensor for detecting that the reel R is in the state shown in FIG. 37B. However, as described above, the angle β formed by the reel R and the extrusion plate 103p varies. For this reason, detection by a sensor is extremely difficult.

  A carrier tape take-up and storage device 101 as a comparative example shown in FIG. 17 has a placement sensor 107p and an upper limit sensor 107u shown in FIG. 20B at the top of the stocker 107, and FIG. (A) It has the full sensor 107f shown in (b). Among them, the full load sensor 107f has a light source (not shown) and a detector (not shown) arranged in the detection window 107fw shown in FIGS. 35 (a) and 35 (b) as described above. This is called a reflective sensor and is inexpensive. However, in order to reflect the light emitted from the light source to the detection object, a detection object having a very short length in the direction parallel to the detection window 107fw, such as the reel receiving plate 107a shown in FIGS. In this case, the detection accuracy becomes low.

  For this reason, it is necessary to project the detection plate 107d having a certain length in a direction parallel to the detection window 107fw below the reel receiving plate 107a. Further, with respect to the placement sensor 107p and the upper limit sensor 107u shown in FIG. 20B, it is necessary to detect the reel R placed on the reel receiving plate 107a as shown in FIGS.

  As shown in FIGS. 2A, 2B and 2C, the reel R has a circular outer periphery, and in the case of an inspection object having this shape, a reflective sensor such as the full load sensor 107f can be used. Can not. Therefore, sensors such as a placement sensor 107p and an upper limit sensor 107u shown in FIG. This is called a counter-type sensor, and the price is about six times that of a reflective sensor. Of the three sensors included in the carrier tape take-up and storage device 101, two are expensive counter-type sensors, which increases the cost as a whole.

  Also, the drive mechanism for raising and lowering the reel receiving plate 107a in the directions of arrows A1 and A2 shown in FIG. 19C has a large number of parts and is expensive. Specifically, the components of the drive mechanism include a motor 107m, a gear 107g, a chain 107c, a roller 107r, and a conveyance fixing surface 107tf and a first conveyance surface 107t1 illustrated in FIG. There are the second transport surface 107t2, the connecting body 107j, the first wheel 107w1, the second wheel 107w2, the third wheel 107w3, the fourth wheel 107w4, etc., and the components of the parts related to the lifting and lowering of the reel receiving plate 107a That is, there are many members. In addition, there are many parts to be assembled with each other, and time is required for manufacturing.

  Further, when the chain 108c shown in FIG. 19C is hung around the gear 107g and the roller 107r, the position of the motor 107m is first moved upward by using an adjustment mechanism (not shown), and the chain 107c is loosened. 107g and the roller 107r are hung around, and then the position of the motor 107m is moved downward by the adjusting mechanism so that a sufficient tension is applied to the chain 107c and the gear 107g is securely fitted. Such adjustment work also takes time. That is, in the comparative example, the portion related to the raising and lowering of the reel receiving plate 107a has a large number of members and requires time for assembly and adjustment, and thus the cost increases.

  Furthermore, the control of the raising / lowering is also complicated. As described above, when the reel R is placed on the reel receiving plate 107a, the detection information of the placement sensor 107p arranged at the top of the stocker 107, the upper limit sensor 107u and the full load sensor 107f arranged at the bottom is confirmed. While the motor 107m is driven, each time one reel R is placed on the reel receiving plate 107a, the reel receiving plate 107a is moved from the upper limit position to the lower limit position, and approximately one reel R is provided. It is stopped after being lowered by a distance corresponding to the thickness of the. As described above, when the reel R is stored in the stocker 107 in a predetermined quantity and the reel R is lifted from the stocker 107 by the operator, the reel receiving plate 107a is moved to the lower limit position. To the upper limit position at once. Such control is performed by software, but every time the reel R is placed on the reel receiving plate 107a while checking the detection information of the placement sensor 107p, the upper limit sensor 107u and the full load sensor 107f, the reel receiving plate 107a is chopped. It is stopped when lowered. Furthermore, when detecting when the reel R mounted on the reel receiving plate 107a reaches a predetermined quantity, the detection information of both the mounting sensor 107p and the full load sensor 107f must be confirmed. That is, the software is complicated and its scale increases. This is also a factor that increases costs.

  Next, FIG. 16 shows the result of comparison of the member cost, manufacturing and adjustment time, and software scale of the carrier tape winding and storing apparatus 1 according to the present invention and the carrier tape winding and storing apparatus 101 according to the comparative example.

  In FIG. 16, when the value of each item in the mechanism of the comparative example is 1, the value of the corresponding item in the mechanism of the present invention is shown as a ratio.

  As shown in FIG. 16, the first difference is that the mechanism of the carrier tape take-up and storage device 1 of the present invention is greatly reduced in the number of members compared to the mechanism of the carrier tape take-up and storage device of the comparative example. Along with this, the material cost is greatly reduced.

  As described above, the members in the comparative example are the motor 107m, the gear 107g, the chain 107c, the roller 107r shown in FIG. 19C, and the conveyance fixing surface 107tf and the first conveyance surface 107t1 shown in FIG. 2 conveyance surface 107t2, connecting body 107j, first wheel 107w1, second wheel 107w2, third wheel 107w3, fourth wheel 107w4, and the like.

  In contrast, the members in the present invention include the transport unit 8 in FIG. 5, that is, the guides 8a1s and 8a2s, the reel holding plates 8h1 and 8h2, the reel transport bars 8rt1 and 8rt2, the reel fixing bar 8f, the cylinder 9 in FIG. It is. Clearly there are fewer members in the mechanism of the present invention. Furthermore, in the comparative example, a total of three sensors, two expensive counter-type sensors and one inexpensive reflective sensor, were used. However, in the present invention, one expensive counter-type sensor is used. As a whole, it contributes to the reduction of material costs. As shown in FIG. 16, the member cost is reduced by 38% in the mechanism of the present invention compared to the mechanism of the comparative example.

  The second difference is that the time required for manufacture and adjustment of the mechanism of the carrier tape take-up and storage device of the present invention is reduced compared to the mechanism of the carrier tape take-up and storage device of the comparative example. The first reason is that the number of members is decreasing. The production time is reduced by reducing the number of parts. The second reason is that in the mechanism of the comparative example, the motor 107m shown in FIG. 19C is used as a drive mechanism for raising and lowering the reel receiving plate 107a shown in FIG. In the mechanism of the invention, the cylinder 9 shown in FIG. 6 is used as a drive mechanism for raising and lowering the transport unit 8 shown in FIG.

  In manufacturing related to the motor 107m in the mechanism of the comparative example, when the chain 108c shown in FIG. 19C is hung around the gear 107g and the roller 107r as described above, the position of the motor 107m is moved up and down. After the chain 107c is loosened, it must be hung around the gear 107g and the roller 107r, and then it is necessary to apply sufficient tension to the chain 107c so that the chain 107c is securely fitted to the gear 107g. This adjustment takes a considerable amount of time.

  On the other hand, in manufacturing related to the cylinder 9 in the mechanism of the present invention, the amount of compressed air supplied into the cylinder 9 from the air supply / discharge ports 9io1 and 9io2 shown in FIG. 9 is adjusted. In this method, first, the adjusting screws 9io1a and 9io2a provided in the air supply / discharge ports 9io1 and 9io2 are rotated to set the amount of the compressed air, and then the compressed air is supplied to the cylinder 9 by the air supply / discharge ports 9io1 and 9io2. Supplying and discharging are performed, and the ascending / descending time of the table 9t between the standby position and the lower end position at that time is measured by a stopwatch so as to be within a predetermined time range. However, this is not a trial-and-error adjustment, and the number of rotations of the adjustment screws 9io1a and 9io2a such that the lifting / lowering time of the table 9t falls within the above time range is, for example, “full adjustment screw”. "Two turns from the tightened position" is determined. Therefore, the time required for the adjustment is much shorter than the adjustment related to the motor 107m in the mechanism of the comparative example described above. For these two reasons, as shown in FIG. 16, the manufacturing and adjusting time is reduced by 47% in the mechanism of the present invention compared to the mechanism of the comparative example. This is equivalent to a 47% cost reduction.

  The third difference is that the scale of software is reduced in the mechanism of the carrier tape take-up and storage device of the present invention compared to the mechanism of the carrier tape take-up and storage device of the comparative example. In the mechanism of the comparative example, when the motor 107m shown in FIG. 17 is driven to raise and lower the reel receiving plate 107a, the placement sensor 107p shown in FIG. 20B, the upper limit sensor 107u, and the full load sensor 107f shown in FIG. The software controls the drive based on the detection results of the three sensors. At that time, as described above, when lowering the receiving plate 107a, each time one reel R is placed on the reel receiving plate 107a, the reel receiving plate 107a is moved from the upper limit position to the lower limit position. It is stopped after being lowered by a distance corresponding to the thickness of one reel R. Furthermore, when detecting the time when the reel R mounted on the reel receiving plate 107a reaches a predetermined quantity, the detection information of both the mounting sensor 107p and the full load sensor 107f is confirmed. Further, when the reel R is stored in the stocker 107 in a predetermined quantity, and the worker raises the reel R from the stocker 107, the motor 107m is driven to move the reel receiving plate 107a from the lower limit position. It is raised at a stretch to the upper limit position. The software that performs these controls is complex and large.

  On the other hand, in the mechanism of the present invention, when the cylinder 9 shown in FIG. 6 is driven to raise and lower the conveyance unit 8, the conveyance unit 8 is simply raised and lowered between the standby position and the lower end position. There is no stopping on the way. Further, when detecting the time point when the reel R mounted on the reel receiving plate 7a reaches a predetermined quantity, only the detection information of the reel sensor 7r shown in FIG. . The raising and lowering of the transport unit 8 is not related to the detection information of the reel sensor 7r. Further, since the transport unit 8 is in the standby position at the time of restarting, it is not necessary to raise or lower it. The software that performs these controls is very simple and small in scale.

  Thus, the software scale related to the raising and lowering of the transport unit 8 in the mechanism of the present invention is very small compared to the software scale related to the raising and lowering of the reel receiving plate 107a in the mechanism of the comparative example. As shown in FIG. 16, the software scale is reduced by 57% with respect to the mechanism of the comparative example. This is equivalent to a cost reduction of 57%.

  In the present embodiment, the reel R is in contact with the inclined surface formed on the guide of the transport unit 8 and is tilted in the direction of the reel receiving plate 7a. When holding, the reel may be held substantially vertically without forming an inclined surface on the guide.
