As a result, the feeder device 81 is communicatively connected to the control device 6 and power is supplied.

Arm members 33 are fixed to both ends of the front side of the flat surface portion 321 in the X-axis direction. The two arm members 33 are formed so as to initially extend horizontally forward, then incline forward and downward, and have a tip extending horizontally forward. The two arm members 33 project to the front side of the machine base 9 when the parts supply device 3 is equipped. A standard reel holding portion 35 is arranged above the inclined portion of the arm member 33 and the horizontal portion on the front side. The standard reel holding portion 35 is arranged lower than the flat surface portion 321 and does not interfere with the attachment / detachment of the feeder device 81. A handle 355 is attached to the lower side of the standard reel holding portion 35. By pulling the handle 355, the entire device pallet 31 can be removed from the machine base 9.

The standard reel holding portion 35 is provided separately from the feeder device 81. The standard reel holding portion 35 is formed of a bottom plate, two side plates 351 and 20 partition plates 352, two shaft members 353, and the like, which are not visible in FIG. The two side plates 351 are substantially right-angled triangular plate materials. The first side sandwiching the right angle of the plate material extends in the front-rear direction, the second side sandwiching the right angle extends in the vertical direction on the rear side, and the hypotenuse extends from the lower front side to the upper rear side. As shown in FIG. 2, the two side plates 351 are arranged in parallel at a separation distance equivalent to the width dimension of the device pallet 31 and fixed to the bottom plate.

The 20 partition plates 352 are plate materials long in the front-rear direction. These partition plates 352 are arranged parallel to the side plates 351 and at equal intervals with each other, and are fixed to the bottom plate. A single reel accommodating portion 361 is partitioned between the partition plates 352 at both ends and the two side plates 351 respectively. A total of two single reel accommodating portions 361 accommodate one tape reel TR interchangeably. A double reel accommodating portion 362 is partitioned between the partition plates 352. A total of 19 double reel accommodating portions 362 accommodate two tape reels TRs side by side in the X-axis direction so as to be exchangeable. Therefore, the maximum number of tape reels TR held by the standard reel holding portion 35 is 40, which is the same as the number of 40 strips of the slot 322.

Two round bar-shaped shaft members 353 are bridged by connecting the front side side near the bottom of the two side plates 351 and the rear side side to each other. The two parallel front and rear shaft members 353 each pass through a shaft hole formed in each partition plate 352. Inside the single reel accommodating portion 361, two rollers rotatably supported by two front and rear shaft members 353 are arranged. The two front and rear rollers rotatably support the outer circumference of the tape reel TR. Inside the double reel accommodating portion 362, two rollers rotatably supported by two front and rear shaft members 353 and arranged in the X-axis direction are arranged. A total of four rollers are paired with two front and rear rollers to rotatably support the outer circumference of the tape reel TR.

By using two rollers that are separated from each other in the front-rear direction with respect to one tape reel TR, it is possible to replace and rotateably support a plurality of types of tape reel TRs having different outer diameter dimensions. Not limited to this, three or more points on the outer circumference of one tape reel TR may be supported. Further, the outer peripheral surface of the shaft member 353 can be smoothly finished and the roller can be omitted.

The conventional feeder device 81 is mounted in one slot 322 and requires one tape reel TR. Therefore, regarding the holding of the tape reel TR, only the configuration of the standard reel holding portion 35 is sufficient. However, when the new feeder device 3 is provided in the component supply device 3, it becomes necessary to hold a larger number of tape reel TRs than the conventional feeder device 81.

For example, the splicingless feeder (also referred to as an autoloading feeder device 82) of Patent Document 3 is mounted in the slot 322 of the first row, but requires two tape reels TR in order to omit the splicing work. .. A multi-feeder device (see, for example, Patent No. 4856761) that supplies parts from two carrier tapes is also mounted in slot 322 of Article 1 and requires two tape reels TR. Further, the composite feeder device in which a plurality of tape feeders exemplified in Patent Document 1 are compositely integrated also requires a larger number of tape reel TRs than the number occupied by the slot 322.

2. 2. Configuration and mounting method of the additional reel holding device 7 As described above, when it becomes necessary to increase the number of carrier tapes that hold and feed a larger number of tape reel TRs than before, the additional reel holding device 7 is used. Used. FIG. 3 is a perspective view illustrating a state in which seven additional reel holding devices 7 are additionally attached to the component supply device 3. FIG. 3 illustrates one autoloading feeder device 82 as an example of a new type of feeder device. In reality, a large number of feeder devices 81 and 82 are mounted on the feeder mounting portion 32, and feeder devices 81 and 82 of different types and structures may be used in combination. FIG. 4 is a side view illustrating the structure and mounting method of the additional reel holding device 7. FIG. 5 is a perspective view illustrating a state in which one additional reel holding device 7 is additionally attached to the component supply device 3.

As shown in FIG. 3, the additional reel holding device 7 holds an additional five tape reels TR between the two side plates 71. The additional reel holding device 7 is mounted side by side on the front side of the standard reel holding portion 35. The additional reel holding device 7 is composed of two side plates 71, a front bottom plate 73, a support shaft 74, a holding shaft 75, and the like.

As shown in FIG. 4, the upper shape of the side plate 71 is formed in a mountain shape descending from the top portion 711 to the front end portion 712 and the rear end portion 713 on the rear side. The lower shape of the side plate 71 is formed by connecting an inclined portion 714, a bottom portion 715, and a second bottom portion 716. The inclined portion 714 is formed diagonally downward and rearward from the tip portion 712. The bottom portion 715 is formed horizontally from the lower rear end of the inclined portion 714 toward the rear side. The second bottom portion 716 is formed horizontally from the rear end of the bottom portion 715 to the upper side and then to the rear side, and reaches the rear end portion 713.

The front bottom plate 73 is arranged in an inclined manner, and the inclined portions 714 of the two side plates 71 are connected to each other. The support shaft 74 interconnects the positions of the two side plates 71 slightly above the bottom 715 and slightly behind the top 711. The presser shaft 75 interconnects the positions of the two side plates 71 near the tops 711. The front bottom plate 73, the support shaft 74, and the holding shaft 75 ensure that the two side plates 71 are separated and parallel to each other, and a reel holding space is formed between the two side plates 71.

The support shaft 74 and the presser shaft 75 have a round bar shape. The support shaft 74 and the presser shaft 75 may have rollers like the shaft member 353 of the standard reel holding portion 35, or the rollers may be omitted. The five tape reels TR are set in the reel holding space from between the front bottom plate 73 and the holding shaft 75. The front bottom plate 73 and the support shaft 74 arranged in the front-rear direction jointly support the outer periphery of the tape reel TR so as to be rotatable. The presser shaft 75 presses the upper part of the outer circumference of the floating tape reel TR so that the tape reel TR does not fall off due to the tension of the carrier tape CT pulled out from the tape reel TR.

It is not always necessary to set five tape reels TR, and the number may be four or less. When the number of additional tape reel TRs used is 4 or less, an empty tape reel TR may be set together to fill the gap in the reel holding space.

The additional reel holding device 7 is attached by using concave attachment portions 721 and 717 formed at two front and rear positions on the lower side of the two side plates 71. More specifically, the mounting member 72 is attached downward to the front of the bottom 715 of the side plate 71. A front concave mounting portion 721 that opens downward is formed on the lower side of the mounting member 72. Further, the second bottom portion 716 of the side plate 71 is also formed with a rear concave mounting portion 717 that opens downward. The openings of the front concave mounting portion 721 and the rear concave mounting portion 717 gradually widen toward the lower side.

On the other hand, on the side of the standard reel holding portion 35, two rod-shaped mounting seats 38 and 39 extending in the X-axis direction are additionally provided. More specifically, at the front ends of the two arm members 33, arm extension members 37 extending toward the front are additionally provided. A front rod-shaped mounting seat 38 is additionally provided by connecting the front upper portions of the two arm extension members 37 separated in the X-axis direction. Further, a rear rod-shaped mounting seat 39 is additionally provided by connecting the front ends of the two side plates 351 separated in the X-axis direction of the standard reel holding portion 35.

The additional reel holding device 7 is mounted and mounted from above on the front rod-shaped mounting seat 38 and the rear rod-shaped mounting seat 39. The front concave mounting portion 721 engages the front rod-shaped mounting seat 38 from above, and the rear concave mounting portion 717 engages the rear rod-shaped mounting seat 39 from above. Therefore, the additional mounting of the additional reel holding device 7 is extremely easy because it is simply mounted.

The position of the additional reel holding device 7 in the front-rear direction (Y-axis direction) is determined by engagement at a total of four points. Further, the rear end portion 713 of the side plate 71 of the additional reel holding device 7 is inserted between the adjacent partition plates 352 of the standard reel holding portion 35, or between the partition plate 352 and the side plate 351. As a result, the additional reel holding device 7 is restricted from moving in the X-axis direction.

3. 3. Action of the additional reel holding device 7 According to the above configuration, the standard reel holding unit 35 can hold 40 tape reels TR, and the 7 additional reel holding devices 7 have a total of 35 tape reels. Can hold TR. As a result, the total number of carrier tape CTs that can be fed to the feeder devices 81 and 82 will increase from the initial 40 to 75 after the additional reel holding device 7 is attached. Since the additional reel holding device 7 is arranged farther than the standard reel holding portion 35 when viewed from the feeder devices 81 and 82, a problem occurs even if the carrier tape CT is fed in a slightly oblique direction. No.

According to the embodiment, even if a new type of feeder device is mounted on the feeder mounting portion 32 and it is necessary to feed a larger number of carrier tape CTs than before, the total number of carrier tape CTs that can be fed is not insufficient. For example, carrier tape that can be fed even when 35 autoloading feeder devices 82 and multi-feeder devices that require two tape reel TRs per slot and five conventional feeder devices 81 are used together. The total number of CTs is not insufficient.

Further, the number of additional reel holding devices 7 arranged side by side in the X-axis direction can be freely selected within the range of 1 shown in FIG. 5 to 7 shown in FIG. Further, as shown by an arrow M in FIG. 5, the mounting position of the additional reel holding device 7 can be changed to a desired position in the X-axis direction. That is, the number and mounting positions of the additional reel holding devices 7 can be freely changed according to the types of feeder devices 81 and 82, the number of mounted reel devices 7, and the arrangement status.

In the example of FIG. 3, the autoloading feeder device 82 uses the first carrier tape CT fed from the tape reel TR of the standard reel holding unit 35. Further, the auto-loading feeder device 82 holds the tip of the second carrier tape CT fed from the tape reel TR of the additional reel holding device 7, and is ready for next use. That is, the additional tape reel TR of the additional reel holding device 7 is used after the tape reel TR held by the standard reel holding unit 35.

The first and second carrier tape CTs are fed diagonally backward and upward from the tape reel TR, respectively, and are inserted from the tape insertion port on the front side of the autoloading feeder device 82. The first and second carrier tape CTs are largely separated from each other in the vertical direction near the tape reel TR, and approach each other toward the autoloading feeder device 82. According to this, the delivery routes of the first and second carrier tape CTs are not complicated.

When the first carrier tape CT disappears in the autoloading feeder device 82, the second carrier tape CT is pulled out from the tape reel TR of the additional reel holding device 7. The operator removes the empty tape reel TR, which has finished feeding the first carrier tape CT, from the standard reel holding portion 35 at the right time. As a result, the standard reel holding portion 35 has an idle reel holding position.

Next, the operator transfers the tape reel TR from which the second carrier tape CT is pulled out from the additional reel holding device 7 to the idle reel holding position of the standard reel holding portion 35. Further, the operator sets the tape reel TR around which the third carrier tape CT for holding the same type of parts is wound in the vacant reel holding space of the additional reel holding device 7. The operator then pulls out the tip of the third carrier tape CT and inserts it into the autoloading feeder device 82. The above-mentioned replacement work of the tape reel TR can be performed even while the component mounting machine 1 is in operation. Therefore, in the auto-loading feeder device 82, the supply of parts is not interrupted even if the splicing work is not performed.

Further, the multi-feeder device mounted on the feeder mounting unit 32 uses the tape reel TR held by the standard reel holding unit 35 and the additional tape reel TR of the additional reel holding device 7 at the same time. At this time, the splicing work can be performed by the standard reel holding unit 35 and the additional reel holding device 7 even while the component mounting machine 1 is in operation. According to this, the multi-feeder device can feed and pull back each carrier tape CT fed from the two tape reels TR, and can alternately supply two kinds of parts. Further, also in the multi-feeder device, the point that the feeding routes of the first and second carrier tape CTs are not complicated is the same as in the case of the auto-loading feeder device 82.

4. Aspects and Effects of the Additional Reel Holding Device 7 The additional reel holding device 7 includes a plurality of feeder devices 81, 82, and a carrier tape CT that feed out carrier tape CTs for holding a plurality of parts and sequentially supply the parts. An additional reel holder that has a standard reel holding unit 35 that holds a plurality of wound tape reels TR in a rotatable and replaceable manner and can be additionally attached to a parts supply device 3 equipped in the parts mounting machine 1.

The carrier tape CT wound around the TR can be fed to the feeder devices 81 and 82.

The additional reel holding device 7 is additionally attached to the parts supply device 3 when the number of carrier tape CTs fed from the standard reel holding unit 35 provided in the parts supply device 3 is insufficient, and an additional tape reel is added. The TR can be held and the carrier tape CT can be fed from the additional tape reel TR to the feeder device 82. As a result, the total number of carrier tape CTs that can be fed from the standard reel holding unit 35 and the additional reel holding device 7 to the feeder devices 81 and 82 can be increased.

Further, the component mounting machine 1 does not need to be modified, and the existing standard reel holding portion 35 can be used as it is. Therefore, the additional reel holding device 7 is compactly formed, is easy to use, and suppresses an increase in cost, as compared with the conventional technique in which the entire reel holding portion is newly manufactured and replaced.

Further, since the additional reel holding device 7 can be used regardless of the type and structure of the feeder devices 81 and 82, it is excellent in compatibility performance and versatility.

Further, the additional reel holding device 7 has a concave shape that is open downward and engages from above with respect to the rod-shaped mounting seats 38 and 39 extending in the X-axis direction (direction in which a plurality of feeder devices are arranged in a row). It is provided with mounting portions 721 and 717. According to this, the additional reel holding device 7 can be additionally attached very easily.

Further, the mounting position of the additional reel holding device 7 can be changed in the X-axis direction (the rowing direction of a plurality of feeder devices). According to this, the mounting position of the additional reel holding device 7 can be freely changed according to the types of feeder devices 81 and 82, the number of mounted reel devices, the arrangement status, and the like, so that the range of application is wide and easy to use.

According to this, the number of additional reel holding devices 7 can be freely changed according to the types of feeder devices 81 and 82, the number of mounted reel devices 7, the arrangement status, and the like, so that the range of application is wide and easy to use.

Further, the additional reel holding device 7 is attached to the front side of the standard reel holding portion 35 away from the feeder devices 81 and 82. According to this, even if the carrier tape CT fed from the additional reel holding device 7 is fed in a slightly oblique direction, no problem occurs. Further, the two carrier tape CTs fed from the standard reel holding portion 35 and the additional reel holding device 7 do not have complicated feeding routes. Therefore, the operation reliability of the component supply device 3 is high.

Further, when the multi-feeder device is used, the additional tape reel TR is used at the same time as the tape reel TR held by the standard reel holding unit 35. Further, when the auto-loading feeder device 82 is used, the additional tape reel TR is used after the tape reel TR held by the standard reel holding portion 35, and is held by the standard reel holding portion 35. When the TR is removed and an idle reel holding position is generated, the TR is transferred to the reel holding position.

According to these, the additional reel holding device 7 can perform the replacement work of the tape reel TR and the splicing work of the carrier tape CT even while the component mounting machine 1 is in operation, and is excellent in workability.
