接着,参照图2及图7对载带输送装置21进行说明。图7是载带输送装置21的YZ俯视图。Next, the carrier tape conveying device 21 will be described with reference to FIGS. 2 and 7 . FIG. 7 is a YZ plan view of the carrier tape conveying device 21 .

载带输送装置21在带输送路径20的下游侧将载带7向部件供给位置P1输送。载带输送装置21具备主框架62、至少1个链轮、马达25、以及将马达25的动力传递给链轮并使其旋转的多个驱动齿轮。本实施方式的载带输送装置21具备第一链轮26、第二链轮28、第三链轮30这三个链轮。The carrier tape conveyance device 21 conveys the carrier tape 7 to the component supply position P1 on the downstream side of the tape conveyance path 20 . The carrier tape conveying device 21 includes a main frame 62, at least one sprocket, a motor 25, and a plurality of drive gears that transmit the power of the motor 25 to the sprocket and rotate it. The carrier tape conveying device 21 of this embodiment includes three sprockets: a first sprocket 26 , a second sprocket 28 , and a third sprocket 30 .

第一链轮26在能够以与X方向平行的水平的旋转轴为中心相对于主框架62旋转的状态下装配。第二链轮28在能够以与X方向平行的水平的旋转轴J(参照图4)为中心相对于主框架62旋转的状态下装配。第三链轮30在能够以与X方向平行的水平的旋转轴为中心相对于主框架62旋转的状态下装配。The first sprocket 26 is mounted in a state of being rotatable relative to the main frame 62 about a horizontal rotation axis parallel to the X direction. The second sprocket 28 is mounted in a state of being rotatable relative to the main frame 62 about a horizontal rotation axis J (see FIG. 4 ) parallel to the X direction. The third sprocket 30 is assembled in a state of being rotatable relative to the main frame 62 about a horizontal rotation axis parallel to the X direction.

载带输送装置21还具备传递马达25的驱动力的多个驱动齿轮,马达25的输出经由这些多个齿轮分别向第一链轮26、第二链轮28、及第三链轮30传递。The carrier tape conveying device 21 further includes a plurality of drive gears that transmit the driving force of the motor 25, and the output of the motor 25 is transmitted to the first sprocket 26, the second sprocket 28, and the third sprocket 30 via these gears.

接着,参照图8对载带输送装置21的主框架62进行说明。图8是载带输送装置21的XZ平面的纵剖视图。Next, the main frame 62 of the carrier tape conveying device 21 will be described with reference to FIG. 8 . FIG. 8 is a longitudinal cross-sectional view of the carrier tape conveying device 21 in the XZ plane.

如图8所示,主框架62具有作为侧面的第一面62L和第二面62R,该第一面62L和第二面62R沿着载带7在带输送路径20上的输送方向纵横(与YZ平面平行)地扩展。主框架62是被第一面62L和第二面62R夹着的厚度尺寸T小的板状构件。因此,与载带7的输送方向正交的主框架62的剖面(XZ剖面)为纵长。As shown in FIG. 8 , the main frame 62 has a first surface 62L and a second surface 62R as side surfaces, which are vertical and horizontal along the conveying direction of the carrier tape 7 on the tape conveying path 20 (with respect to The YZ plane expands parallel). The main frame 62 is a plate-shaped member with a small thickness T between the first surface 62L and the second surface 62R. Therefore, the cross section (XZ cross section) of the main frame 62 orthogonal to the conveyance direction of the carrier tape 7 is vertically long.

主框架62在上部形成有平坦的输送面62g,该输送面62g用于沿着带输送路径20引导载带7。在输送面62g上形成有供各链轮的销突出的多个开口部。例如,在开口部622中,第二链轮28的销28a比输送面62g突出。进而,在其下游的开口部623中,第三链轮30的销30a比输送面62g突出。The main frame 62 is formed with a flat conveyance surface 62g on the upper portion for guiding the carrier tape 7 along the tape conveyance path 20 . A plurality of openings through which the pins of each sprocket protrude are formed in the conveyance surface 62g. For example, in the opening 622, the pin 28a of the second sprocket 28 protrudes from the conveyance surface 62g. Furthermore, in the downstream opening 623, the pin 30a of the third sprocket 30 protrudes from the conveyance surface 62g.

这些销28a、30a插入位于输送面62g的载带7的进给孔7d。因此,当第一~第三链轮26、28、30旋转时,载带7被各链轮的销送出,沿着输送面62g移动。在第一~第三链轮26、28、30的下方配置有异物接受部59,该异物接受部59将进入各链轮的销之间的异物向异物排出孔62h及异物排出口62m引导。These pins 28a and 30a are inserted into the feed hole 7d of the carrier tape 7 located on the conveyance surface 62g. Therefore, when the first to third sprockets 26, 28, and 30 rotate, the carrier tape 7 is sent out by the pins of each sprocket and moves along the conveyance surface 62g. A foreign matter receiving portion 59 is disposed below the first to third sprockets 26, 28, and 30. The foreign matter receiving portion 59 guides foreign matter entering between the pins of each sprocket to the foreign matter discharge hole 62h and the foreign matter discharge port 62m.

接着,参照图7及图8对落在销28a之间的异物93的回收进行说明。异物93例如是灰尘、在带馈送器6的更换作业中从载带7飞散的部件16等。Next, the recovery of the foreign matter 93 dropped between the pins 28a will be described with reference to FIGS. 7 and 8 . The foreign matter 93 is, for example, dust, components 16 scattered from the carrier tape 7 during the replacement operation of the tape feeder 6 , or the like.

异物接受部59接受从各开口部进入并被各链轮的销夹着而残留在链轮表面的异物93,该异物93随着链轮的旋转而落下。例如,在主框架62的内部,第二链轮28的销28a的前端被异物接受部59包围。异物接受部59配置在主框架62与内罩38之间。The foreign matter receiving portion 59 receives the foreign matter 93 that enters through each opening and is sandwiched by the pins of each sprocket to remain on the surface of the sprocket. The foreign matter 93 falls as the sprocket rotates. For example, inside the main frame 62 , the front end of the pin 28 a of the second sprocket 28 is surrounded by the foreign matter receiving portion 59 . The foreign matter receiving portion 59 is arranged between the main frame 62 and the inner cover 38 .

异物接受部59具有第一异物引导部59b和第二异物引导部59c,该第一异物引导部59b和第二异物引导部59c将异物93分别向作为排出部的异物排出孔62h及异物排出口62m引导。第一异物引导部59b例如将随着第二链轮28的旋转而进入主框架62内的异物93向配置于第二链轮28的下方的凹槽59a引导。第一异物引导部59b是异物接受部59的上表面的一部分,沿着连结第二链轮28的各个销28a的前端的圆形成。The foreign matter receiving portion 59 has a first foreign matter guide portion 59b and a second foreign matter guide portion 59c that guide the foreign matter 93 toward the foreign matter discharge hole 62h and the foreign matter discharge port, respectively. 62m to boot. The first foreign matter guide portion 59 b guides the foreign matter 93 that enters the main frame 62 as the second sprocket 28 rotates, for example, to the groove 59 a arranged below the second sprocket 28 . The first foreign matter guide portion 59 b is a part of the upper surface of the foreign matter receiving portion 59 and is formed along a circle connecting the front ends of the pins 28 a of the second sprocket 28 .

凹槽59a是从第一异物引导部59b向下方凹陷的凹部,与形成于主框架62的、和外部连通的异物排出孔62h连接。落在销28a之间的异物93与第二链轮28一起旋转,落下到第一异物引导部59b、被收集在凹槽59a中。异物排出孔62h配置于凹槽59a所处的部分,例如配置于凹槽59a的下部。作业者能够回收通过异物排出孔62h被收集在凹槽59a中的异物93。The groove 59a is a recessed portion recessed downward from the first foreign matter guide portion 59b, and is connected to the foreign matter discharge hole 62h formed in the main frame 62 and communicating with the outside. The foreign matter 93 dropped between the pins 28a rotates together with the second sprocket 28, falls to the first foreign matter guide portion 59b, and is collected in the groove 59a. The foreign matter discharge hole 62h is arranged in the part where the groove 59a is located, for example, in the lower part of the groove 59a. The operator can collect the foreign matter 93 collected in the groove 59a through the foreign matter discharge hole 62h.

在第三链轮30的下方,通过异物接受部59形成有第二异物引导部59c。第二异物引导部59c与第三链轮30的旋转一起将落到主框架62内的异物93向异物排出口62m引导。第二异物引导部59c是异物接受部59的上表面的一部分,向下方倾斜。从第三链轮30落到第二异物引导部59c中的异物93因自重沿着第二异物引导部59c移动,从异物排出口62m向主框架62的外部排出。A second foreign matter guide portion 59 c is formed below the third sprocket 30 by the foreign matter receiving portion 59 . The second foreign matter guide portion 59c guides the foreign matter 93 dropped into the main frame 62 toward the foreign matter discharge port 62m together with the rotation of the third sprocket 30. The second foreign matter guide portion 59c is a part of the upper surface of the foreign matter receiving portion 59 and is inclined downward. The foreign matter 93 dropped from the third sprocket 30 into the second foreign matter guide portion 59c moves along the second foreign matter guide portion 59c due to its own weight, and is discharged from the foreign matter discharge port 62m to the outside of the main frame 62.

接着,参照图9对链轮的销的长度进行说明。图9是链轮的局部侧视图。在此,对第二链轮28的销28a的长度进行说明,但第一链轮26的销、第三链轮30的销30a也可以是同样的结构。Next, the length of the sprocket pin will be described with reference to FIG. 9 . Figure 9 is a partial side view of the sprocket. Here, the length of the pin 28a of the second sprocket 28 is described, but the pins of the first sprocket 26 and the pin 30a of the third sprocket 30 may have the same structure.

第二链轮28的销28a的上部比载带7的输送面62g向上方突出。与从载带7的输送面62g向上方突出的部分的销28a的长度Lp1相比,未从输送面62g突出的部分Lp2的长度长。换言之,从第二链轮28的销底28d到载带7的输送面62g的长度Lp2比从载带7的输送面62g突出的第二链轮28的销28a的长度Lp1长。由此,即使异物93落在两个销28a之间,由于销28a的长度Lp2长,因此能够降低异物93侵入到比输送面62g靠下方的位置而夹在开口部622的边缘与销28a之间的情况。The upper part of the pin 28a of the second sprocket 28 protrudes upward from the conveyance surface 62g of the carrier tape 7. The length of the portion Lp2 that does not protrude from the conveyance surface 62g is longer than the length Lp1 of the pin 28a of the portion that protrudes upward from the conveyance surface 62g of the carrier tape 7 . In other words, the length Lp2 from the pin bottom 28d of the second sprocket 28 to the conveyance surface 62g of the carrier tape 7 is longer than the length Lp1 of the pin 28a of the second sprocket 28 protruding from the conveyance surface 62g of the carrier tape 7. Therefore, even if the foreign matter 93 falls between the two pins 28a, since the length Lp2 of the pin 28a is long, it can be reduced that the foreign matter 93 invades below the conveyance surface 62g and is caught between the edge of the opening 622 and the pin 28a. situation during the period.

另外,第二链轮28的销28a的全长Lp3比部件16的最大尺寸大。换言之,到第二链轮28的销前端28e的半径Rt与第二链轮28的销底28d的半径Rb之差Lp3比部件16的最大尺寸大。由此,即使部件16作为异物93落入两个销28a之间,夹在开口部622的边缘与销28a之间的情况也能够被进一步降低。In addition, the overall length Lp3 of the pin 28a of the second sprocket 28 is larger than the maximum dimension of the member 16. In other words, the difference Lp3 between the radius Rt to the pin front end 28e of the second sprocket 28 and the radius Rb of the pin bottom 28d of the second sprocket 28 is larger than the maximum dimension of the component 16. Accordingly, even if the component 16 falls between the two pins 28 a as the foreign object 93 , the situation that the component 16 is caught between the edge of the opening 622 and the pins 28 a can be further reduced.

另外,第二链轮28的销28a的全长Lp3比相邻的销28a的根部部分的间隔即销间距离Dp长。由此,即使在异物93侵入开口部622内而残留在第二链轮28的销28a之间的情况下,也能够进一步避免异物93被销28a与开口部622的边缘夹住而无法输送载带7这样的故障。另外,在第二链轮28的销28a之间捕捉异物93的能力变高,能够降低在载带输送装置21的内部变得下落不明的可能性。In addition, the total length Lp3 of the pins 28a of the second sprocket 28 is longer than the inter-pin distance Dp, which is the distance between the root portions of adjacent pins 28a. Therefore, even if the foreign matter 93 invades the opening 622 and remains between the pins 28a of the second sprocket 28, it can be further prevented that the foreign matter 93 is caught between the pins 28a and the edges of the opening 622 and fails to convey the load. With 7 such glitches. In addition, the ability to capture the foreign matter 93 between the pins 28 a of the second sprocket 28 becomes higher, and the possibility that the foreign matter 93 becomes unaccounted for inside the carrier tape conveying device 21 can be reduced.

本实施方式的载带输送装置21输送载带7,该载带7收纳部件16并且以规定的间距Pt1设置有进给孔7d。载带输送装置21具备主框架62和第二链轮28。主框架62具有从下方支承并引导被输送的载带7的输送面62g。第二链轮28具有与进给孔7d的间距Pt1相对应地呈放射状突出的多个销28a,第二链轮28通过使销28a一边从形成于输送面62g的开口部622向上方突出一边旋转而使销28a与进给孔7d卡合来输送载带7。与销28a从输送面62g突出的部分的长度LP1相比,销28a隐藏在输送面62g下方的部分的长度Lp2长。The carrier tape conveyance device 21 of this embodiment conveys the carrier tape 7 which accommodates the components 16 and is provided with feed holes 7d at a predetermined pitch Pt1. The carrier tape conveying device 21 includes a main frame 62 and a second sprocket 28 . The main frame 62 has a conveying surface 62g that supports and guides the conveyed carrier tape 7 from below. The second sprocket 28 has a plurality of pins 28a that protrude radially corresponding to the pitch Pt1 of the feed hole 7d. The second sprocket 28 has the pins 28a protruding upward from the opening 622 formed in the conveyance surface 62g. By rotating, the pin 28a is engaged with the feed hole 7d, and the carrier tape 7 is conveyed. The length Lp2 of the portion of the pin 28a hidden below the conveyance surface 62g is longer than the length LP1 of the portion of the pin 28a protruding from the conveyance surface 62g.

即使在作为异物的异物93从开口部622侵入内部而残留在第二链轮28的销28a之间的情况下,由于销28a的长度Lp2比长度Lp1长,因此异物93也容易落到输送面的下方。由此,能够避免异物93被夹在销28a与开口部622的边缘之间而无法输送载带7这样的故障。Even if the foreign matter 93 as a foreign matter invades the inside from the opening 622 and remains between the pins 28a of the second sprocket 28, the length Lp2 of the pins 28a is longer than the length Lp1, so the foreign matter 93 easily falls onto the conveyance surface. below. This can avoid a problem in which the foreign object 93 is caught between the pin 28 a and the edge of the opening 622 and the carrier tape 7 cannot be conveyed.

另外,在本实施方式的载带输送装置21中,销28a的全长Lp3比相邻的销28a的根部部分的间隔即销间距离Dp长。由此,能够进一步降低异物93被夹在销28a与开口部622的边缘之间的情况。进而,将异物93捕捉在第二链轮28的销28a之间的能力变高,降低在载带输送装置21的内部异物93变得下落不明的可能性。In addition, in the carrier tape conveying device 21 of this embodiment, the total length Lp3 of the pins 28a is longer than the inter-pin distance Dp which is the distance between the root portions of adjacent pins 28a. This can further reduce the possibility of foreign matter 93 being sandwiched between the pin 28 a and the edge of the opening 622 . Furthermore, the ability to capture the foreign matter 93 between the pins 28 a of the second sprocket 28 becomes higher, thereby reducing the possibility that the foreign matter 93 becomes unaccounted for inside the carrier tape conveyance device 21 .

另外,在本实施方式的载带输送装置21中,在第二链轮28的下方具有接受随着第二链轮28的旋转而落下的异物93的异物接受部59,该异物93为从开口部622进入并残留在第二链轮28的被销28a夹着的表面的异物。In addition, in the carrier tape conveying device 21 of the present embodiment, a foreign matter receiving portion 59 is provided below the second sprocket 28 to receive the foreign matter 93 dropped from the opening as the second sprocket 28 rotates. The foreign matter that enters the portion 622 and remains on the surface of the second sprocket 28 sandwiched by the pins 28 a.

在专利文献1的结构中,落下到带馈送器内的部件等异物有可能在带馈送器内部的间隙中自由地移动,变得下落不明的异物有可能成为故障的原因。在本实施方式的载带输送装置21中,通过异物接受部59能够防止异物93向载带输送装置21的内部的预料之外的场所移动。In the structure of Patent Document 1, foreign matter such as components that have fallen into the tape feeder may move freely in gaps inside the tape feeder, and the foreign matter that becomes unaccounted for may cause a malfunction. In the carrier tape conveying device 21 of the present embodiment, the foreign matter receiving portion 59 can prevent the foreign matter 93 from moving to an unexpected place inside the carrier tape conveying device 21 .

另外,本实施方式的载带输送装置21在异物接受部59中具有将异物93向异物排出孔62h及异物排出口62m引导的第一及第二异物引导部59b、59c。在专利文献1中,将侵入带馈送器的内部的异物取出至带馈送器的外部是繁杂的,但通过第一及第二异物引导部59b、59c能够可靠且容易地排出侵入载带输送装置21的内部的异物93。In addition, the carrier tape conveying device 21 of this embodiment has the first and second foreign matter guide portions 59b and 59c in the foreign matter receiving portion 59 that guide the foreign matter 93 to the foreign matter discharge hole 62h and the foreign matter discharge port 62m. In Patent Document 1, it is complicated to take out the foreign matter that has invaded the inside of the tape feeder to the outside of the tape feeder. However, the first and second foreign matter guide portions 59b and 59c can reliably and easily discharge the foreign matter that has invaded the tape conveying device. 21 Internal foreign objects 93.

另外,在本实施方式的载带输送装置21中,在第一异物引导部59b中设置有向下方凹陷的部分,并形成有收集落下到第一异物引导部59b的异物93的凹槽59a。由此,能够进一步抑制侵入到载带输送装置21的内部的异物93在装置内部自由移动的情况。In addition, in the carrier tape conveying device 21 of this embodiment, the first foreign matter guide portion 59b is provided with a downwardly recessed portion, and a groove 59a is formed to collect the foreign matter 93 dropped to the first foreign matter guide portion 59b. This can further suppress the foreign matter 93 that has invaded the inside of the carrier tape conveying device 21 from freely moving inside the device.

另外,在本实施方式的载带输送装置21中,异物排出孔62h配置于凹槽59a所处的部分。由此,能够可靠地排出侵入到载带输送装置21的内部的异物93。In addition, in the carrier tape conveying device 21 of this embodiment, the foreign matter discharge hole 62h is arranged in the portion where the groove 59a is located. Thereby, the foreign matter 93 which invaded the inside of the carrier tape conveyance device 21 can be reliably discharged.

另外,本实施方式的带馈送器6输送以规定的间距Pt1设置有进给孔7d的载带7,将收纳于载带7的部件16向部件供给位置P1供给。带馈送器6具备上述的载带输送装置21,通过载带输送装置21输送载带7而向部件供给位置P1供给部件16。In addition, the tape feeder 6 of this embodiment conveys the carrier tape 7 provided with the feed holes 7d at a predetermined pitch Pt1, and supplies the components 16 accommodated in the carrier tape 7 to the component supply position P1. The tape feeder 6 is provided with the carrier tape conveying device 21 described above, and the carrier tape 7 is conveyed by the carrier tape conveying device 21 to supply the components 16 to the component supply position P1.
