In order to achieve this object, the present invention provides a pressing means for pressing the transport band after the cutting operation of the lead terminal by the cutting means.
That is, if the transport band is pressed by the pressing unit after the cutting operation of the lead terminal by the cutting unit, the transport band can be reliably separated from the lead terminal in an incompletely cut state.

According to a second aspect of the present invention, there is provided the component mounting apparatus according to the first aspect, wherein the pressing means is configured to press the transport band in a longitudinal direction thereof. If the transfer belt itself is pressed in the longitudinal direction, it is easy to transmit the pressing force by the pressing means to the lead terminal without buckling if the transfer belt itself is pressed in the longitudinal direction. Can be surely separated.

According to a third aspect of the present invention, in the component mounting machine according to the second aspect, the pressing means has a concave groove in a longitudinal direction of the lead wire. Since it is a configuration with a concave groove in the longitudinal direction of the lead wire,
By the concave groove of the pressing means, it is possible to reliably press the transport band in its longitudinal direction. That is, in a state in which the carrier is wrapped in the concave groove, the carrier is pressed in the longitudinal direction, so that the carrier band can be reliably separated from the lead wire.

According to a fourth aspect of the present invention, there is provided the component mounting machine according to the third aspect, wherein the pressing means comprises a lever having a concave groove at one end and a fulcrum at the other end. Since the pressing means is constituted by a lever, the groove can be largely rotated about the fulcrum on the other end side of the lever, thereby reliably separating the transport band from the lead terminal. Can be done.

According to a fifth aspect of the present invention, there is provided the component mounting machine according to the fourth aspect, wherein the fulcrum of the pressing means is provided on a cutting side of the groove. When the band is pressed, a force is applied such that the pressing means presses the transport band in a substantially parallel direction, and thereby the transport band is easily separated from the lead terminals.

Next, according to the invention described in claim 6 of the present invention, the cutting means and the pressing means are driven by a single cam. Since the cutting means and the pressing means are driven by a single cam, pressing by the pressing means is performed at the end of the cutting operation, that is, the timing of both is not disrupted, and the lead This allows the transport belt to be reliably separated from the terminal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a component body, and the component body 1 is fixed to one end of two lead terminals 2. On the other end side of the lead terminal 2, a transport band 3 is
Has been fixed. In other words, in the apparatus shown in FIG. 1, what is conveyed by a long belt-shaped conveyance band is separated into individual conveyance bands 3 shown in FIG. Are shown in FIG. FIG. 1 shows a state in which the transport band 3 is separated from the lead terminals 2. In this case, the center part of the lead terminal 2 is held by the left and right holding means 4, and the side of the transport band 3 is cut by the left and right cutting blades 6 from the holding part.

More specifically, the left and right cutting blades 6 are pressed strongly below the holding means 4 to separate the transport band 3 from the lead terminals 2. In this case, first, the cutting blade 6 is strongly pressed against the lead terminal 2, and in this pressed state, the pressing means 7 presses the transport band 3 to the left side in FIG.

That is, even if the transport band 3 cannot be reliably separated from the lead terminal 2 by the cutting blade 6,
By pressing the conveying band 3 to the left side in FIG. 1 by the pressing means 7, the conveying band 3 is separated from the lead terminal 2 which is in an insufficiently cut state. In this case, as shown in FIG. 1, the pressing means presses the transporting band 3 in the longitudinal direction, that is, the left side in FIG.
Has a concave groove 8 in the longitudinal direction of the lead terminal 2.

Therefore, the transport band 3 is pressed to the left side in FIG. 1 in a state where the transport band 3 is fitted into the concave groove 8. In order to perform such an operation, the pressing means has a concave groove 8 on one end side, and is constituted by a lever 10 pivotally supported by a fulcrum 9 on the other end side. FIG. 2 shows the state of the fulcrum 9 and the holding means 7. As shown in FIG. 2, when the pressing means 7 is not rotating, the fulcrum 9 is closer to the transport belt 3.

In this state, a fulcrum is located at an intermediate portion between the transport band 3 and the pressing means 7. By providing the fulcrum 9 at such a position, when the pressing means 7 is pressed toward the transport band, a force is applied such that the pressing means 7 presses the transport band 3 in a substantially parallel direction, and thereby the transport from the lead terminal 2 is performed. The band 3 can be easily separated without fail.

For comparison, when the fulcrum 9 is located on the right side of the holding means 7 as shown in FIG. 3, the pressing means 7 is moved downward from the state of FIG. 3 as shown in FIG. Then, a state in which a force is applied to the transport belt 3 is obtained. In this case, a sufficient force will be applied to the right one of the lead terminals 2, but the force is not applied to the left one, and the left lead terminal 2 may remain. On the other hand, if the fulcrum 9 is provided on the left side of the pressing means 7 as shown in FIG. 2, the holding means 7 moves in a parallel direction, so that the transport band 3 can be more easily separated from the lead terminals 2. Things.

As described above, the cutting blade 6 and the pressing means 7 always perform the cutting operation of the lead terminal 2 in the operation, and when the cutting means 6 is still left by the pressing means 7, it is transported. The band 3 is pressed. In order to perform such a coordinated operation, the cutting blade 6 and the pressing means 7 are driven by one cam 11 as shown in FIG. In FIG. 4, two cam plates 12 and 13 are actually provided even though one cam 11 is provided, and the cam follower 14 and the lever 15 are turned on one of the cam plates 12 so that the cutting blade 6 is moved. The cam plate 13 is connected to a pressing means 7 by rotating a cam follower 16 and a lever 17.
