When the shutter technology disclosed in Patent Document 2 is applied to the component mounter of Patent Document 1, there is only one tape discharge port for discharging the waste tape fed by a plurality of tape feeders toward the tape cutting machine. It has a structure that opens and closes with a shutter. In this case, the shutter opens the tape ejection port while the tape feeder is placed on the feeder set table. On the other hand, when the tape feeder is not placed on the feeder setting table, the shutter closes the tape discharge port. Exposure of the tape cutter can be suppressed in a state in which the shutter closes the tape discharge port.

By the way, in the component mounter, only the tape feeders necessary for producing component-mounted boards are attached to the component mounter. In other words, in the mounter disclosed in Patent Document 1, the tape feeders are not arranged over the entire area in which the tape feeders can be arranged side by side on the feeder setting table, and there may be a feeder unarranged area where the tape feeders are not arranged. . In this case, the shutter opens the tape discharge port according to the arrangement of the tape feeder with respect to the feeder set stand, but the tape cutting machine is exposed from the portion of the tape discharge port corresponding to the feeder unarranged area.

The degree of exposure of the tape cutter through the tape exit increases as the feeder unplaced area increases. If the degree of exposure of the tape cutter increases excessively, there is a risk that the exposure of the tape cutter cannot be suppressed appropriately.

(Third embodiment)
A feeder housing structure 5B according to the third embodiment will be described with reference to FIGS. 13 to 16. FIG. The feeder housing structure 5B according to the third embodiment is arranged at a position where the main body side opening 2A is formed in the mounting machine main body 2 of the component mounting machine 1, similarly to the feeder housing structure 5A according to the above-described second embodiment. It is a structure that is arranged and configured to accommodate a plurality of tape feeders TF. The configuration of the plurality of shutters 8B in the feeder accommodation structure 5B is slightly different from the plurality of shutters 8A in the feeder accommodation structure 5A. Since the feeder containing structure 5B is configured in the same manner as the feeder containing structure 5A except for the above, detailed description of the similar components will be omitted, and different components will be described.

A plurality of shutters 8B in the feeder housing structure 5B have shutter portions 81B and pressed portions 82B. The shutter portion 81B has a function of opening and closing the tape ejection port 6C, like the first shutter portion 81A of the shutter 8A described above. The shutter portion 81B is movable between a closed position and an open position to open and close the tape ejection port 6C. The pressed portion 82B extends upward from the shutter portion 81B and is movable together with the shutter portion 81B. However, the pressed portion 82B does not have the function of the second shutter portion 82A in the shutter 8A described above, and the upward extension length from the shutter portion 81B is equal to the upper end of the pressed portion 82B. The length is set so as to be located below the lower positioning hole 73 of 7 .

The plurality of shutters 8B are arranged side by side so that each shutter portion 81B can appear and disappear with respect to each shutter movement guide 64 of the housing main body 6 . During movement of each shutter 8B, the shutter portion 81B is guided by the inner wall of each shutter movement guide 64. As shown in FIG.

The plurality of shutters 8B open and close the tape discharge port 6C separately and independently by each shutter portion 81B according to the insertion/removal of the tape feeder TF with respect to each of the plurality of holding portions 7 . That is, in each of the plurality of shutters 8B, a pressing force is applied to the pressed portion 82B from the tape feeder TF that is inserted into the holding portion 7 along the insertion direction XX1, thereby causing the shutter portion 81B to move. While being guided by the guide 64, it moves to the open position where the tape ejection port 6C is opened. On the other hand, when the tape feeder TF is extracted from the holding portion 7 along the extraction direction XX2, the application of the pressing force from the tape feeder TF to the pressed portion 82B is released, so that the shutter portion 81B is a shutter movement guide. While being guided by 64, it moves to the closing position for closing the tape ejection port 6C.

In each of the plurality of shutters 8B, the shutter section 81B has a first light passage hole 811B and a second light passage hole 812B, like the first shutter section 81A of the shutter 8A described above. The first light passage hole 811B and the second light passage hole 812B are holes that allow passage of light in the detection mechanism 9. The shutter portion 81B is arranged in the side-by-side direction YY with a predetermined gap in the insertion/removal direction XX. provided to pass through. Further, the shutter portion 81B of the shutter 8B has a first lock pin insertion hole 813B and a second lock pin insertion hole that allow the lock pin 102 of the lock mechanism 10 to pass through, similarly to the first shutter portion 81A of the shutter 8A described above. 814B.

Among the plurality of shutters 8B, in the shutter 8B corresponding to the holding portion 7 into which the tape feeder TF is inserted, the shutter portion 81B is arranged at the open position to open the tape discharge port 6C. In this case, the shutter section 81B is arranged at the open position, so that the carrier tape TP1 after component removal is fed by the tape feeder TF inserted in the holding section 7 from the tape discharge port at the downstream end of the tape feed path TF3. It can be introduced into the tape cutter 21 via 6C.

On the other hand, among the plurality of shutters 8B, in the shutter 8B corresponding to the holding portion 7 from which the tape feeder TF has been pulled out, the shutter portion 81B is arranged at the closing position for closing the tape discharge port 6C. In this case, since the exposure of the tape cutter 21 through the tape discharge port 6C can be restricted by arranging the shutter portion 81B at the closed position, the exposure of the tape cutter 21 can be appropriately suppressed. It becomes possible.

Next, the relationship between the plurality of shutters 8B and the plurality of holding portions 7 will be described with reference to FIG. In the example shown in FIG. 15A, the number of installed shutters 8B is the same as the number of installed holding portions 7, and the shutters 8B are installed corresponding to each of the plurality of holding portions 7. In the example shown in FIG.

At this time, as shown in FIGS. 15B and 15C, the plurality of shutters 8B may be arranged side by side so that gaps are formed between adjacent shutters 8B. In this case, the separation distance SD along the juxtaposition direction YY between the shutters 8B adjacent to each other in the plurality of shutters 8B is It is set to be less than twice the distance HD. FIG. 15B shows an example in which the separation distance SD between the shutters 8B adjacent to each other is set to one time the distance HD between the centers of the holding portions 7 adjacent to each other. FIG. 15C shows an example in which the distance SD between the shutters 8B adjacent to each other is set to twice the distance HD between the centers of the holding portions 7 adjacent to each other.

As described above, the separation distance SD between the shutters 8B adjacent to each other in the plurality of shutters 8B is set to be equal to or less than the predetermined value based on the distance HD between the centers of the holding portions 7 adjacent to each other. As a result, the degree of exposure of the tape cutter 21 from the gap between the shutters 8B adjacent to each other can be determined appropriately in a state where the shutter 8B is arranged at the closed position for closing the tape discharge port 6C. It can be kept within a controllable range. The technical concept of setting the distance SD between the shutters 8B adjacent to each other may be applied to the feeder housing structure 5 according to the first embodiment and the feeder housing structure 5A according to the second embodiment. good.

Next, the relationship between the multiple shutters 8B and the tape feeder TF will be described with reference to FIG. In the example shown in FIG. 16A, the number of installed shutters 8B is the same as the number of installed holding portions 7, and the shutters 8B are installed corresponding to each of the plurality of holding portions 7. In the example shown in FIG. In this case, the width dimension along the direction YY of the shutters 8B and the width dimension along the direction YY of the tape feeders TF are substantially the same. The width dimension of the tape feeder TF in this case is referred to as "reference feeder width dimension".

The width dimension of the tape feeder TF to be inserted into each holding portion 7 is not always the standard feeder width dimension. As shown in FIG. 16B, a tape feeder TF having a width dimension larger than the reference feeder width dimension may be inserted into the holding portion 7 . Also, as shown in FIG. 16C, there may be a case where a tape feeder TF having a width dimension smaller than the reference feeder width dimension is inserted into the holding portion 7 .

Even when a plurality of types of tape feeders TF with different width dimensions are used, the plurality of shutters 8B opens and closes the tape discharge port 6C according to the insertion/removal of the tape feeders TF with respect to the plurality of holding portions 7, respectively. That is, among the plurality of shutters 8B, the shutter 8B corresponding to the holding portion 7 into which the tape feeder TF is inserted opens the tape discharge port 6C, while the shutter 8B corresponding to the holding portion 7 from which the tape feeder TF is extracted opens. closes the tape ejection port 6C. Therefore, in the tape discharge port 6C, the area corresponding to the holding portion 7 into which the tape feeder TF is inserted is closed by the tape feeder TF as the shutter 8B is placed in the open position.
