Problems to be Solved by the Invention

The tape feeder of Patent Document 1 is configured to increase the number of tape suppliers that can be inserted into the feeder main body by reducing the width of the tape supplier to the same size as the width of the component supply tape. .. For this reason, the tape holder portion and the tape pressing plate on the tip side of the tape supplier are also reduced in size and thickness, their mechanical strength is weakened and they are easily deformed. On the top side of the feeder main body, there is a supplier insertion guide plate that covers the tip side of the tape supplier inserted in the slot from above, but the tip of the tape supplier is inserted between the supplier insertion guide plate and the slot. Since it is necessary to provide a clearance (gap) for inserting the side part, the tip side part of the tape supplier is lifted by the above-mentioned clearance, and the cover tape (top The tape pressing plate that presses the component supply tape may be deformed so as to float due to the tensile force when peeling the tape. As a result, the suction height position of the component in the component supply tape is not stable, and the component suction operation becomes unstable, which is a factor that causes a component suction failure (absorption posture abnormality) or suction failure (suction failure). Was becoming.

Therefore, the problem to be solved by the present invention is to provide a tape feeder capable of stabilizing the component suction position by stabilizing the component height position of the component supply tape at the component suction position on the tip side of the tape supplier. That is.

In order to solve the above problems, the present invention is configured to detachably mount a slot in a feeder body of a tape feeder, and supply a component supply tape in which a large number of components are arranged at a predetermined pitch to a component suction position. Oite the supplier, on the upper surface of the feeder body, the slot supplier insertion guide member for covering from above provided the distal portion of the tape supplier attached to the, the said supplier insertion guide member, the tape supplier Is formed with a component suction opening for sucking the component in the component supply tape set at the component suction position, and the tape supplier has a tape holder portion for receiving the component supply tape supplied to the component suction position. And a tape pressing plate that presses the rising of the component supply tape on the tape holder part, and a rising edge part that rises upward from the side edge part of the tape pressing plate or the side edge part of the tape holder part. The supplier insertion guide member is provided with a holder pressing portion with which the rising piece of the tape supplier mounted in the slot contacts, and the rising piece contacts the holder pressing portion when the tape supplier is mounted. The tape holding plate and the tape holder portion are configured so as to press the rising of the tip side portion.

With this configuration, when the tape supplier is mounted, the rising piece portion abuts the holder pressing portion on the supplier insertion guide member side, so that it is possible to suppress the rising of the tape pressing plate and the tip side portion of the tape holder portion. It is possible to stabilize the component height position of the component supply tape at the component suction position on the front end side of the component and stabilize the component suction operation, and it is possible to reliably reduce the frequency of component suction failure and suction error. ..

When the present invention is carried out, for example, the tape pressing plate is formed of an elastic plate such as a leaf spring, and the rising piece is provided on one side edge part of the tape pressing plate and the part abutting the holder pressing part is inward. An upper surface of the component supply tape is formed between the tape retainer plate and the supplier insertion guide member by forming the bent retainer into a substantially inverted L-shape so that the rising piece contacts the holder retainer when the tape supplier is mounted. The cover tape peeled off from the component supply tape may be pulled in a direction opposite to the feeding direction of the component supply tape to secure a gap for recovery.

If the tape holding plate is formed of an elastic plate such as a leaf spring in this way, when the component supplying tape is set in the tape supplier, the elastic deformation of the tape holding plate is used to move the component supplying tape to the tape holder portion and the tape. It becomes easier to insert it between the holding plate and the component supply tape, making it easier to set. Further, by forming a rising piece having a substantially inverted L-shaped cross section on one side edge of the tape pressing plate, it is possible to more reliably prevent the tape pressing plate from rising, and at the same time, to prevent the tape pressing plate and the supplier insertion guide member from being separated from each other. A space for collecting the cover tape separated from the upper surface of the component supply tape can be surely secured between them.

Furthermore, a structure may be provided which includes height position adjusting means for adjusting the height position of the holder pressing portion. By doing so, even if the thickness dimension of the tip side portion of the tape supplier or the thickness dimension of the component supply tape is different, the height position of the holder pressing portion is adjusted to an appropriate height according to the thickness dimension. It is possible to adjust the height of the tape supplier, and it is possible to stably suppress the lifting of the tip side portion of the tape supplier.

Correspondingly, a positioning hole 78 (see FIG. 2), which is a positioning means for positioning the tape supplier 21, is formed in the lower step portion of the operation panel 42 of the holding member 41 of the feeder body 13, and the tape supplier 21 By inserting the positioning pin 77 of the handle portion 76 into the positioning hole 78 on the lower side of the operation panel 42 when the feeder is attached to the feeder main body 13, the tape supplier 21 attached to the feeder main body 13 causes the operation panel 42 of the holding member 41 to operate. It is positioned with respect to the lower surface of the. In this embodiment, the tape supplier 21 can be mounted in the slot 18 of the feeder main body 13 with the tape feeder 11 set on the feeder set table 66 of the mounter.

As shown in FIG. 6, a plate-shaped supplier insertion guide member 45 is attached to the upper surface of the tip end side portion of the feeder main body 13 to cover the tip end side portion of the tape supplier 21 mounted in the slot 18 from above. The guide member 45 is formed with a component suction opening 46 for sucking the component in the component supply tape 19 set in the tape supplier 21 at the component suction position. The component suction opening 46 of the supplier insertion guide member 45 also plays a role of fitting and holding both ends of the component supply tape 19 in the width direction near the component suction position to position the component supply tape 19 in the width direction. ..

As shown in FIGS. 4 and 5, on the tip side of the tape supplier 21, a rail-shaped tape holder portion 51 for supporting the component supply tape 19 to be supplied to the component suction position, and a component supply on the tape holder portion 51. A tape pressing plate 52 for pressing the rising of the tape 19 is provided, and the component supply tape 19 is sandwiched between the tape holder portion 51 and the tape pressing plate 52 and held in a tape feedable state. ..

The tape pressing plate 52 is formed of an elastic plate such as a leaf spring, and is located above one of the side edges of the tape pressing plate 52 at a position before the component suction opening 46 (component suction position). A rising piece portion 53 that stands up is provided. The rising piece portion 53 has an upper portion bent inward in the width direction of the tape pressing plate 52 and has a substantially inverted L-shaped cross section so that it does not project to the outside in the width direction of the tape pressing plate 52. The rising piece 53 may be formed integrally with the tape pressing plate 52, or a separate piece may be attached and fixed to the tape pressing plate 52. The rising piece portion 53 is preferably formed of an elastic plate such as a leaf spring in the same manner as the tape pressing plate 52 in order to absorb dimensional variations.

On the other hand, as shown in FIGS. 7 and 8, on the supplier insertion guide member 45, the holder pressing portion 55 projects downward at a position corresponding to the rising piece portion 53 of the tape supplier 21 mounted in the slot 18 of the feeder body 13. When the tape supplier 21 is mounted, the rising piece portion 53 comes into contact with the holder pressing portion 55 to press the lifting of the tape pressing plate 52 and the tip end side portion of the tape holder portion 51. The holder pressing portion 55 is attached to the supplier insertion guide member 45 by a height adjusting screw 56 (height position adjusting means), and the height position of the holder pressing portion 55 can be adjusted by adjusting the tightening amount of the height adjusting screw 56. It is like this.

In this case, when the tape supplier 21 is mounted, the rising piece portion 53 of the tape pressing plate 52 contacts the holder pressing portion 55 on the supplier insertion guide member 45 side, so that the tape pressing plate 52 and the supplier insertion guide member 45 are separated from each other. The cover tape 20 separated from the upper surface of the component supply tape 19 is pulled into the cover tape recovery case 24 located in the direction opposite to the feeding direction of the component supply tape 19 so as to secure a gap for recovering the cover tape 20. The height dimension of the portion 53 and the like are set.

In the present embodiment described above, the rising piece portion 53 rising upward from the side edge portion of the tape pressing plate 52 on the tip side of the tape supplier 21 is provided, and the supplier insertion guide member 45 is provided with the tape attached to the feeder body 13. Since the holder pressing portion 55 with which the rising piece 53 of the supplier 21 abuts is provided, the rising piece 53 abuts the holder pressing portion 55 on the supplier insertion guide member 45 side when the tape supplier 21 is mounted. It is possible to suppress lifting of the tape pressing plate 52 and the tip end side portions of the tape holder portion 51. This makes it possible to stabilize the height position of the component of the component supply tape 19 at the component suction position on the tip side of the tape supplier 21 and stabilize the component suction operation, thereby reducing the frequency of occurrence of component suction failure or suction error. It can be surely reduced.

Further, in this embodiment, since the tape pressing plate 52 is formed of an elastic plate such as a leaf spring, when the component supply tape 19 is set in the tape supplier 21, the elastic deformation of the tape pressing plate 52 is used to supply the component. The tape 19 can be easily inserted between the tape holder portion 51 and the tape pressing plate 52, and the work of setting the component supply tape 19 can be facilitated.

Further, in this embodiment, since the rising piece portion 53 having a substantially inverted L-shaped cross section is formed on one side edge portion of the tape pressing plate 52, the tape pressing plate 52 can be more reliably prevented from rising and the tape pressing plate 52 can be more reliably prevented. There is an advantage that a gap for collecting the cover tape 20 separated from the upper surface of the component supply tape 19 can be reliably ensured between the plate 52 and the supplier insertion guide member 45. However, in the present invention, the tape holder portion 51 is provided with a rising piece portion that rises upward from the side edge portion, and the rising piece portion abuts the holder pressing portion 55 on the supplier insertion guide member 45 side. It is also possible to suppress the rise of the tip end side portion of 51 and thereby the rise of the tape pressing plate 52.

Further, in this embodiment, since the height adjusting screw 56 for adjusting the height position of the holder pressing portion 55 is provided, even if the thickness dimension of the tip side portion of the tape supplier 21 or the thickness dimension of the component supply tape 19 is different. The height position of the holder pressing portion 55 can be adjusted to an appropriate height position by the height adjusting screw 56 according to its thickness dimension, and the lifting of the tip side portion of the tape supplier 21 can be stably pressed. There is an advantage that
