SUMMARY

In a component supply device configured including a tape feeder and tape reel as above, it is necessary to collect and dispose of waste tape that is tape after components have been picked up from the component holding tape. There is also a problem of an increased amount of waste tape due to the increase in tape reels. Generally, a waste tape collection device for collecting waste tape is provided below a tape feeder, but because with a component mounter that uses the cart disclosed in the above patent literature 1, a reel stock section and a large reel holding section are provided, it is difficult to collect and dispose of waste tape collected in the waste tape collection device. The present disclosure takes account of such circumstances, and an object thereof is to provide a holding device for tools required for component supply for which it is easy to collect and dispose of waste tape.

To solve the above problems, a holding device for tools required for component supply of the present disclosure includes:

a feeder attachment table on which multiple tape feeders are attached lined up in a lengthwise direction, the tape feeders being configured to feed component holding tape that holds multiple components and position multiple of the components respectively at a supply position;

a first reel holder provided at a rear side of the feeder attachment table and configured to hold lined up multiple tape reels on which the component holding tape is wound;

a second reel holder provided below the first reel holder and configured to hold lined up multiple of the tape reels; and

a second holder movement allowance mechanism configured to allow the second reel holder to move upwards,

wherein

the second reel holder is able to be positioned at a rear side of the first reel holder.

As described above, there are cases in which a waste tape collection device is provided on a holding device for tools required for component supply or a component mounter main body on which the holding device for tools required for component supply is set, so as to be positioned below a feeder attachment table and in front of a second reel holder. According to the holding device for tools required for component supply of the present disclosure, by using a second holder moving allowance mechanism to move a second reel holder up and position it to the rear of a first reel holder, it is easy to remove a waste tape collection device to the rear of itself.

Note that, the holding device for tools required for component supply of the present disclosure may be configured such that supplying component holding tape to a tape feeder is possible from one of a first reel holder and a second reel holder, and the other of the first reel holder and the second reel holder is for stocking a tape reel, or may be configured such that supplying component holding tape to a tape feeder is possible from both the first reel holder and the second reel holder. Also, the configuration of the second holder moving mechanism is not particularly restricted, so long as it allows the second reel holder to move upwards, for example, the configuration may be such that an upper section of the second reel holder is rotatable around a fulcrum, or such that the second holder can slide upwards.

DESCRIPTION OF EMBODIMENTS

Hereinafter, an example of a holding device for tools required for component supply that is an embodiment of the present disclosure is described with reference to the drawings. It should be noted that for the present disclosure, as well as the below embodiment, embodiments with various changes based on the knowledge of someone skilled in the art are possible.

FIG. 1shows component mounter10that uses a holding device for tools required for component supply that is an embodiment of the present disclosure. Although detailed drawings and descriptions are omitted, component mounter10performs work of conveying a circuit board loaded into component mounter10to a component mounting position using conveyance device12, and picking up components supplied from component supply device14and mounting the components on the circuit board using a component mounting head (not shown). Component mounter10includes two component mounting heads, and those two component mounting heads are provided lined up in the direction in which the circuit board is conveyed by conveyance device12. Note that, inFIG. 1only one component supply device14is shown, but two component supply devices are set, corresponding to the two component mounting heads.

Component supply device14is configured mainly from multiple tape feeders20(also referred to as “feeders”) that position a component at a supply position to be picked up by the component mounting head, and multiple tape reels22and24(also referred to as “reels”) on which is wound component holding tape T supplied to the multiple feeders20. Component supply cart26(also referred to as “cart26”) used as the holding device for tools required for component supply is a configuration element of component supply device14, and holds items such as multiple feeders20and multiple reels22and24that are tools required for component supply. However, inFIGS. 1 and 2, only one each of feeders20and reels22and24are shown; actually, multiple feeders20can be set lined up in the conveyance direction of the components, and, with respect to the multiple feeders20, in a similar manner to the feeders20, multiple reels22and24can be set and lined up in the conveyance direction of the board. Note that, with component supply device14, the side that supplies components, that is, the front side that is the side that faces the main body of component mounter10, is described below with the front side taken as the front side of component supply device14.

As shown inFIG. 3, component holding tape T is configured from carrier tape30and cover tape32. Multiple recess sections34are formed in carrier tape30at even intervals in the lengthwise direction, and multiple electronic circuit components P (also referred to as “P”) are housed in the respective multiple recess sections. Cover tape32is attached to carrier tape30so as to cover the multiple recess sections34, to prevent the components P from coming out of the recess sections34.

Cart26is configured mainly from feeder attachment table40to which the above multiple feeders20are attached, first reel holder42that holds multiple reels22, and second reel holder44that holds multiple reels24. Also, cart26is configured such that the above feeder attachment table40, first reel holder42, and second reel holder44are attached to base56that includes bed50on which are provided a pair of wheels48at the front and rear, frame52established on that bed50, and pair of handles54fixed to the frame52.

Feeder attachment table40is fixed to the top end at the front side of frame52. Feeder attachment table40includes multiple slots60for attaching the feeders20lined up in a left-right direction, such that multiple feeders can be held lined up in the left-direction. That is, for cart26, component supply positions of each of the multiple feeders20are provided lined up in the left-right direction, that is, parallel to the conveyance direction of the board.

Also, first reel holder42(also referred to as “first holder42”) is fixed to frame52at the rear side of feeder attachment table40, such that the upper end of reel22set on first reel holder42is roughly at the same height as feeder20. First holder42includes slots62for each holding reels22lined up in the left-right direction, with the quantity being the same as the multiple slots60included on feeder attachment table40. That is, first holder42is able to hold the same quantity of reels22as the quantity of feeders20that can be set at feeder attachment table40. First holder42is configured including pair of side plates64, and multiple support rollers66provided connecting the pair of side plates64; reel22is held to be rotatable around a center axis line thereof by the multiple support rollers66. Note that, in the descriptions below, reel22held by first holder42is sometimes referred to as “first reel22.”

Second reel holder44(also referred to as “second holder44”) is provided below first holder42. Similar to first holder42, second holder44includes slots70for each holding reels24lined up in the left-right direction, with the quantity being the same as the multiple slots60included on feeder attachment table40. That is, similar to first holder42, second holder44is able to hold the same quantity of reels22as the quantity of feeders20that can be set at feeder attachment table40. Also, similar to first holder42, second holder44is configured including pair of side plates72, and multiple support rollers74provided connecting the pair of side plates72; reel24is held so as to be rotatable around a center axis line thereof by the multiple support rollers74. In the descriptions below, reel24held on second holder44is sometimes referred to as “second reel24.”

The above first holder42and second holder44are able to supply component holding tape T to a corresponding feeder20from a reel22or reel24held on either first holder42or second holder44. As shown inFIG. 4, component holding tape T1wound on first reel22, is pulled out to the front, and is supplied directly to feeder20. On the other hand, component holding tape T2wound on second reel24, is pulled up and is guided to feeder20with the direction being changed forwards by guide rollers76. Because guide rollers76are provided to the rear of first holder42at a position higher than the upper end of first reel22, component holding tape T2wound on second reel24is supplied to feeder20passing above first reel22without contacting first reel22.

Continuing, a simple description will be given of operation of feeder20, with details of feeder20being omitted. Feeder20includes a feeding device, and is configured to intermittently feed component holding tape T forwards while pulling it from first reel22or second reel24. Feeder20successively positions the multiple components held in component holding tape T to a component supply position provided at a front end section of feeder20, so as to supply the components to a component mounting head. Note that, feeder20includes a cover tape peeling device that peels cover tape32from carrier tape30at a position in front of the component supply position.

Then, waste tape that is tape after components have been picked up from component supply tape T, that is, carrier tape30and cover tape32, is guided to waste tape collection box80(also referred to as “collection box80”) that is a waste tape collection device provided on cart26, and is collected inside collection box80. In detail, collection box80is provided on cart26below feeders20and is held so as to be slidable forwards and backwards. As shown inFIG. 4, carrier tape30after components have been picked up is fed further forwards by the feeding device of feeder20, the direction is changed downwards to guide82provided on the main body of component mounter10, is cut to an appropriate length by a tape cutter (not shown) provided in the main body of component mounter10, and is collected in collection box80. On the other hand, as shown inFIG. 4, cover tape32peeled from carrier tape30by the cover tape peeling device, is fed backwards inside feeder20, the direction is changed downwards at the rear end section of feeder20, and is collected in collection box80.

With component mounter10, during component mounting operation, it is necessary to dispose of waste tape that has been collected in collection box80, that is, it is necessary to empty collection box80. However, collection box80is positioned in front of second holder44, so in a state shown inFIGS. 2 and 4, it is impossible to remove collection box80from cart26. Cart26of the present embodiment is provided with second holder movement allowance mechanism100that allows second holder44to be moved upwards. Second holder movement allowance mechanism100rotatably supports second holder44at an upper end section thereof, and allows second holder44to move to the rear of first holder42by second holder44being rotated. Specifically, the upper end of the pair of side plates72that configure second holder44are each rotatably attached to the pair of handles54, such that second holder44is rotatable. Second holder44is configured to be moved upwards by being raised by an operator. Note that, a pair of grips102is provided on second holder44, and a pair of gas springs104are provided between second holder44and bed50, such that an operator can lift second holder44easily and safely.

Also, cart26of the present embodiment is provided with second holder fixing mechanism110that fixes second holder44in a state to the rear of first holder42. Specifically, second holder fixing mechanism110, as shown inFIG. 6(b), is configured including engaging section112fixedly provided on each of the pair of handles54, and engaged section114that engages with engaging section112and is fixed to each of the pair of side plates72, and movement of second holder44is prevented by engaging section112engaging with engaged section114when second holder44is rotated and raised to a position to the rear of first holder42. Thus, according to cart26of the present embodiment, by causing second holder44to be in the raised position shown inFIG. 6(b), it is possible to slide waste tape collection box80rearwards and to easily remove waste tape collection box80from the rear side of cart26. Note that, lever120is provided on each of the pair of grips102, and the engagement of engaging section112and engaged section114can be released by gripping lever120.

Further, with cart26of the present embodiment, as shown inFIG. 6(b), even in a state with second holder44positioned to the rear of first holder42, it is possible to supply component holding tape T2to feeder20from second reel24held by second holder44. Accordingly, when using cart26of the present embodiment, it is possible to remove waste tape collection box80without stopping work by component mounter10.

Note that, with cart26of the present embodiment, except for when removing waste tape collection box80, as shown inFIG. 6(a), by positioning second holder44below first holder42, the space occupied by component supply device14is smaller, such that the space occupied by component mounter10is also small.
