Is continuously moved to the side. The conveying tape 50 wound on the reel 78 in a roll form is released from the reel 78 and moved to the mounter 77 side by the separator 79 formed on the upper portion of the feeder 76. And release paper 81 is separated. At this time, the vinyl tape 91 is pulled by a pair of toothed drive reels 82, and the release paper 81 is moved below the feeder 76 along the moving passage 83 in the drawing.

At this time, the feeder 76 for continuously conveying the transfer tape 50 (consisting of the vinyl tape 90 and the release paper 81) to the mounter 77 side, and the electronic parts supplied to the mounter 77. Detailed description of the fixing device (not shown) for fixing the 80 to a printed circuit board (not shown) or the like is included in the technical details used in the art, and thus detailed descriptions of their configuration and operation will be omitted. .

The transfer tape 50 separated by the above-described separator 79 into the vinyl tape 90 and the release paper 81 is moved toward the inlet 51 formed on the upper surface of the main body 53.

As shown in FIGS. 4 and 5, the transfer tape 50 supplied into the main body 53 through the inlet 51 is provided with a pair of brushes 55 opposed to the lengthwise direction below the inlet 51. By rotation of 56, the main body 53 is pulled toward the inner bottom surface.

At this time, since the rotational force transmitted from the driving motor 54 is transmitted to the driven gears 74 and 75 engaged with the driving gear 73-the driving gear 73, the pair of brushes 55 and 56 rotate in opposite directions. Let's do it.

Accordingly, the transfer tape 50 introduced into the inlet 51 may pass through a pair of brushes 55 and 56 that are engaged with each other and rotated in opposite directions.

For this reason, as the feed tape 50 is forcibly pulled by the rotation of the brushes 55 and 56 and supplied to the cut portion including the cutter 61, the feed tape 50 can be continuously and stably supplied.

At this time, since the transfer tape 50 passing through the pair of brushes 55 and 56 passes through the guider 67 installed below the brushes 55 and 56, the transfer tape 50 is not interrupted by being twisted by components around the transfer. It can be stably supplied to the cut portion.

As described above, when the conveying tape 50 is introduced into the inlet 51 of the main body 53, the compressed air from the nozzle 86 formed to face the upper portion of the inlet 51 is transferred to the conveying tape 50.

Passing through the guider 67 is installed is passed between the support member 57 and the pressing member 59. At this time, the pressing member 59 installed in the frame 60 moved by the driving unit (not shown air cylinder may be used) maintains the stopped initial state (state shown in FIG. 5).

As shown in FIG. 6, a plurality of pressing members are integrally fixed to the frame 60 as the frame 60 is moved to the left in the drawing due to driving of a driving unit (not illustrated air cylinder may be used). 59 is moved toward the supporting member 57. That is, the transfer tape 50 is fixed between the supporting member 57 and the pressing member 59 which are mutually compressed to maintain the tension.

At this time, the cutter 61 integrally fixed to the above-described frame 60 maintains a predetermined distance away from the transfer tape 50.

When the conveying tape 50 is pressed and fixed to maintain the tension by the mutual crimping of the supporting member 57 and the pressing member 59, the cap of the poly urethane carbon material coupled to the outer surface of the pressing member 59 ( 62, the frictional force of the pressing member 59 against the support member 57 can be increased. Therefore, it is possible to prevent the transfer tape 50 from slipping when the transfer tape 50 is cut by the cutter 61.

The pressing force of the pressing member 59 against the supporting member 57 can be increased by the inclined surfaces 63 and 64 formed on the outer surface of the cap 62 of the supporting member 57 and the pressing member 59. have. Therefore, it is possible to prevent the transfer tape 50 from slipping when the transfer tape 50 is cut by the cutter 61.

As shown in FIG. 6, in the state where the pressing member 59 is pressed against the supporting member 57 described above, when the extension driving amount of the air cylinder is slightly increased, the frame 60 moves to the left in the drawing. A little more. Therefore, the transfer tape 50 can be cut by the cutter 61 fixed integrally to the frame 60.

At this time, since the pressing member 59 is continuously pushed against the supporting member 57 by the movement of the frame 60, the transfer tape 50 may maintain a predetermined tension.

Therefore, the conveying tape 50 is smoothly carried out by the cutter 61 in a state where the conveying tape 50 is fixed while maintaining the tension due to the mutual crimping of the supporting member 57 and the pressing member 59 described above. Can be cut
