The lifting device preferably includes a pair of hooks (123, 124) having different lengths for lifting the carrier tape on both sides of the connecting portion, and inclined support portions (123a, 124a) for lifting the carrier tape from one end side in the width direction are formed on the hooks.

Description

Splicing device

Technical Field

The present invention relates to a splicing device for automatically connecting 2 carrier tapes, and more particularly to a splicing device for reliably taking out spliced carrier tapes from the device.

Background

In general, in a component mounting machine, a carrier tape having a plurality of electronic components held at regular intervals is wound around a reel, and the carrier tape is fed by a fixed amount at a time by driving a tape guide gear engaged with a feed hole formed in the carrier tape, so that the electronic components are supplied to a component supply position. Then, the electronic component supplied to the component supply position is sucked by the suction nozzle and mounted on the circuit board.

In such a component mounting machine, when the remaining amount of the electronic components held by 1 reel is lost (decreased), so-called splicing is performed in which a leading end portion of the carrier tape wound around another reel holding the same kind of electronic components is connected to a trailing end portion of the carrier tape having the decreased remaining amount by a splicing tape. For example, patent document 1 describes a technique for automatically performing such splicing.

Problems to be solved by the invention

In this splicing device, the front side (cover tape side) and the back side (tape main body side) of 2 carrier tapes are connected by a splicing tape, respectively.

In this case, the splicing tape is in a state of being adhered to the protective tape, and therefore, if the carrier tape is inadvertently lifted when the carrier tape connected by the splicing tape is taken out, the splicing tape adhered to the carrier tape may be peeled off due to the adhesive force of the splicing tape and the protective tape.

The invention aims to provide a splicing device which automatically connects 2 carrier tapes and reliably takes out the spliced carrier tapes from the device.

Means for solving the problems

In order to solve the above-described problems, the present invention relates to a splicing device for connecting a first carrier tape and a second carrier tape, each having a feed hole and a component-receiving cavity provided at a predetermined interval, to each other with a splicing tape, the splicing device including: a device main body; a cover supported to be openable and closable with respect to the apparatus main body; a positioning device for conveying the first carrier tape and the second carrier tape between the device main body and the cover body in a direction approaching each other and positioning them at a splicing position; a splicing tape that is attached to a protective tape that is transported between the device main body and the cover body in a direction orthogonal to a transport direction of the first carrier tape and the second carrier tape, and is positioned at the splicing position; a connecting device that connects the first carrier tape and the second carrier tape by the splicing tape transferred to the splicing position; and a lifting device having a pair of hooks of different lengths for lifting the connected carrier tape connected by the splicing tape from both sides of the connection portion and separating the splicing tape from the protective tape.

According to the present invention, the spliced carrier tape is lifted by the pair of hooks having different lengths, and the splicing tape can be gradually peeled off from the one end side of the protective tape, so that the splicing tape adhered to the carrier tape is not peeled off. Therefore, the spliced carrier tape can be reliably and easily taken out from the device.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 is a view showing a tape feeder 10 detachably attached to a component supply device of a component mounter, and a tape reel 12 on which a carrier tape T is wound is detachably attached to the tape feeder 10.

As shown in fig. 2 and 3, the carrier tape T is formed to be elongated with a predetermined width, and a plurality of cavities Ct are arranged at regular intervals in the longitudinal direction, and components (electronic components) e mounted on the circuit board are housed in the cavities Ct, respectively. The upper opening of the chamber Ct is covered with a top seal tape Tt attached to the surface of the carrier tape T.

On one end side in the width direction of the carrier tape T, feed holes Hc are formed at the same pitch interval as the chambers Ct or at a pitch interval 2 times as large as the chambers Ct, and these feed holes Hc are arranged in a fixed positional relationship with the chambers Ct.

The tape feeder 10 incorporates a constant-feed mechanism 18, and the constant-feed mechanism 18 feeds the carrier tape T wound around the tape reel 12 by a constant amount one by one to a component supply position 17 provided at a tip portion of the tape feeder 10. The quantitative feeding mechanism 18 is rotatably supported by the main body of the tape feeder 10, and includes a tape guide gear 19 engaged with the feed hole Hc of the carrier tape T and a motor, not shown, for rotating the tape guide gear 19 by 1 pitch per rotation.

The carrier tape T used in the component mounter is composed of plural types having different pitches of the cavities Ct, and the pitch interval of the cavities Ct and the relationship between the cavities Ct and the feed holes Hc are determined according to the type of the carrier tape T. Therefore, by recognizing the pitch interval of the chambers Ct by image processing or the like, it is possible to grasp which kind of the carrier tape T is, and based on this, it is possible to recognize the position of the feed hole Hc of the carrier tape T, and to determine the cutting position of the carrier tape T at the time of splicing described later.

The splicing device 20 is a device that automatically connects the tip end portion of the carrier tape wound on the current reel mounted on the tape feeder 10 mounted on the component supply device and the start end portion of the carrier tape wound on the next reel to be replaced.

As shown in fig. 5, the splicing device 20 includes a box-shaped device body 21 and a cover 22 supported rotatably about a pivot 23 (see fig. 21) on the device body 21 and opening and closing an upper surface of the device body 21, and is configured to be movable between tape feeders 10 mounted on a component supply device of a component mounter such as a carriage (not shown). The cover 22 is manually closed at the time of splicing, and is automatically opened at the time of taking out the spliced carrier tape T. When the lid 22 is once closed, the closed state is maintained by a closure holding device described later.

As shown in fig. 4, the 2 carrier tapes T (hereinafter, referred to as a first carrier tape T1 and a second carrier tape T2) spliced by the splicing device 20 have first chambers Ct1 (second chambers Ct2) for accommodating first components e1 (second components e2) of the same component type, which are arranged at a predetermined pitch Pc.

In addition, a first feed hole Hc1 (second feed hole Hc2) capable of meshing with teeth 67a (67b) of a first belt guide gear 61a (second belt guide gear 61b) of a first belt conveyor 50 (second belt conveyor 51) described later is perforated in the first and second carrier tapes T1, T2 at a predetermined pitch Ph in parallel with the first chamber Ct1 (second chamber Ct 2).

The first and second carrier tapes T1 and T2 are joined together by cutting and butting any of the first and second cutting portions Q1 and Q2 by the splicing device 20 and by a splicing tape 30 described later. As the first cut portion Q1 (second cut portion Q2), for example, an intermediate position between the first chamber Ct1 (second chamber Ct2) of the first element e1 (second element e2) and the empty first chamber Ct1 (second chamber Ct2) without the first element e1 (second element e2) can be selected.

The first carrier tape T1 (second carrier tape T2) connected to the cut empty first chamber Ct1 (second chamber Ct2) is discarded as the first unnecessary part Tf1 (second unnecessary part Tf 2). In order to reserve an arbitrary number of empty first chambers Ct1 (second chambers Ct2), the intermediate position of the adjacent empty first chamber Ct1 (second chamber Ct2) may be selected as the first cut point Q1 (second cut point Q2).

From the left and right in fig. 6, 2 carrier tapes T1 and T2 to be spliced are fed to the splicing device 20, and from the upper direction in fig. 6 orthogonal to the left and right in fig. 6, a protective tape 31 (see fig. 7) to which a splicing tape 30 to which the 2 carrier tapes T1 and T2 are joined is bonded is fed to the splicing device 20. Also, as shown in fig. 7, at a splicing position LS where the carrier tapes T1, T2 and the protective tape 31 cross, the ends of 2 carrier tapes T1, T2 are connected to each other by the splicing tape 30.

Note that the splicing tape 30 joined to the protective tape 31 is fed to the splicing position LS with the bonding surface to which the carrier tapes T1 and T2 are bonded as the upper side, and 2 carrier tapes T1 and T2 are positioned above the splicing tape 30.

As shown in fig. 8 and 9, the splicing tape 30 is composed of 1 set of

splicing tapes

30a and 30b for front and rear surfaces bonded to both surfaces of 2 carrier tapes T1 and T2 on the upper surface of the continuous protective tape 31. That is, the splicing tapes 30 include 1 set of the front surface splicing tape 30a connected to the front surfaces of the 2 carrier tapes T1 and T2 and the back surface splicing tape 30b connected to the back surfaces of the 2 carrier tapes T1 and T2.

The splicing tapes 30 for the front and back sides 1 set are bonded to the protective tape 31 at regular intervals Pd in the longitudinal direction of the protective tape 31 while keeping a predetermined positional relationship with the feed holes 31a perforated at regular intervals on both sides of the protective tape 31. The 1 set of the

splicing tapes

30a and 30b are arranged with the surface splicing tape 30a as the leading side and with a predetermined interval Pd 1. Metal powder is embedded in the 1 set of

splice tapes

30a and 30b, and detection can be performed by a tape detection sensor that can detect metal, which will be described later.

As shown in fig. 9, below the protective tape 31, a tape detection sensor 48 for detecting the

splicing tapes

30a and 30b is provided at a position separated by a predetermined distance S1 from the splicing position LS on the front side of the splicing position LS. From the detection position when the end of the splicing tape 30 (e.g., the back-side splicing tape 30b) is detected by the detection slit 49 by the metal detection sensor 48 described above, the protective tape 31 is fed by the stepping motor 47 of the protective tape conveyor 36 by an amount S1, thereby positioning the splicing tape 30 at the splicing position LS.

The top surfaces of the

splicing tapes

30a and 30b are adhesive surfaces bonded to both surfaces of 2 carrier tapes T1 and T2, and as shown in fig. 8, a continuous backing paper 32 is bonded to the adhesive surfaces, and 3-layer structures of the backing paper 32, the splicing tape 30, and the protective tape 31 are wound around the supply reel 33 in a roll shape.

The protective tape 31 has a width dimension larger than a width dimension of the mount 32, and both ends of the protective tape 31 in the width direction protrude from both ends of the mount 32 in the width direction. On the other hand, the width dimension of the splicing tape 30 is equal to the width dimension of the backing paper 32, and the splicing tape 30 is joined to the protective tape 31 inside the feed hole 31a in 1 set of front and back surfaces.

As shown in fig. 9, in the protective tape 31, a plurality of positioning holes 31b are formed in the width direction of the protective tape 31 at the same pitch interval as the feed holes Hc1 and Hc2 formed in the carrier tapes T1 and T2 at a position close to the surface splicing tape 30 a. In addition, a plurality of positioning holes 30b1 are formed in the rear surface splicing tape 30b so as to penetrate the protective tape 31 at the same pitch interval as the feed holes Hc1 and Hc2 formed in the carrier tapes T1 and T2 and extend in the width direction of the protective tape 31.

After the

splicing tapes

30a and 30b are attached to the protective tape 31 at predetermined positions, the feed holes 31a and the positioning holes 31b formed in the protective tape 31 are formed by punching or the like in accordance with the formation of the positioning holes 30b1 in the splicing tape 30 b.

As shown in fig. 7, in the splicing device 20, a rotatable supply reel 33 for winding a 3-layer structure including the splicing tape 30 into a roll shape, a backing paper transport device 35 for feeding out the backing paper 32 peeled from the splicing tape 30, and a protective tape transport device 36 for feeding out the protective tape 31 peeled from the splicing tape 30 are disposed on a line crossing the splicing position LS where 2 carrier tapes T1 and T2 are spliced.

The adhesive strength with which the backing paper 32 and the protective tape 31 are bonded to both surfaces of the splicing tape 30 is stronger than the adhesive strength with which the protective tape 31 is bonded, and even if the backing paper 32 is peeled off from the splicing tape 30, the splicing tape 30 is not peeled off from the protective tape 31.

However, when the carrier tapes T1 and T2 are bonded to the adhesive surface of the splicing tape 30 from which the backing paper 32 is peeled off, the adhesive force is stronger than the adhesive force to the protective tape 31, and the protective tape 31 is easily peeled off from the splicing tape 30.

The 3-layer structure of the backing paper 32, the splicing tape 30, and the protective tape 31 is assembled to the splicing device 20 in a state of being wound around the supply reel 33, and the leading end is pulled out from the supply reel 33. Then, the operator peels off the interleaving paper 32 and folds it back, and the interleaving paper 32 is sent out by the interleaving paper conveyor 35 and discarded to an interleaving paper storage box, which is not shown.

The supply reel 33 is rotatably supported by a support body 38 attached to the apparatus main body 21. The support body 38 is pressed against the supply reel 33 by a predetermined frictional force generated by a spring force, and the rotation of the supply reel 33 with respect to the support body 38 is regulated by the support body 38. When the protective tape 31 is pulled by a force exceeding the force of friction, the supply reel 33 is rotatable with respect to the support body 38.

The protective tape 31 with the backing paper 32 peeled off, that is, the protective tape 31 with the adhesive surface as the upper side and the plurality of splicing tapes 30 joined thereto, passes through the center of the splicing position LS and passes through a later-described connecting device 58, and the leading end portion thereof is engaged with the feeding tape guide gear 46 of the protective tape conveying device 36 (see fig. 10).

As shown in fig. 10, the feeding tape guide gear 46 is formed with a plurality of engaging teeth 46a at equal angular intervals in the circumferential direction at the same pitch as the pitch of the feeding holes 31a formed in the protective tape 31, and the protective tape 31 engaged with the engaging teeth 46a is fed by a unit amount by driving a stepping motor 47 connected to the feeding tape guide gear 46 at 1 pitch.

The stepping motor 47 is positioned so that the engagement teeth 46a of the feeding belt gear 46 are always positioned at the apex by returning the origin by turning on the power supply. Further, the stepping motor 47 can appropriately restrict the rotation by a rotation restricting unit 47a such as a servo lock device.

The friction action of the support 38 and the rotation restricting unit 47a constitute a stopper that restricts the movement of the protective tape 31 at both ends thereof and prevents the protective tape 31 from floating when the spliced carrier tapes T1 and T2 are taken out of the splicing device 20.

A pressing plate 103a is provided on the swivel table 103 at a position offset from the swivel center, and a plurality of second positioning pins 105 and pin holes 106 are provided on the pressing plate 103 a. The second positioning pins 105 are arranged at positions corresponding to the positions between the first positioning pins 93 and 94 provided on the first elevation table 91, and can be inserted into the pin holes 95 provided on the first elevation table 91. The pin holes 106 are arranged at positions corresponding to the positions between the second positioning pins 105, and the first positioning pins 93 and 94 provided on the first elevating table 91 can be inserted.

The second positioning pins 105 are rotated 180 degrees by the rotating table 103 to engage with the feeding holes Hc of the 2 carrier tapes T1 and T2 positioned at the splicing position LS and the positioning holes 30b1 of the splicing tape 30b, and maintain the positional relationship among the 2 carrier tapes T1 and T2 and the splicing tape 30 connecting the 2 carrier tapes T1 and T2 to be constant.

A pinion gear 107 is attached to the pivot shaft 104 of the revolving table 103, and a rack 108 meshing with the pinion gear 107 is attached to a movable table 109 that is movable in a horizontal direction orthogonal to the conveying direction of the carrier tapes T1, T2. Thus, when the movable stage 109 moves, the swing stage 103 swings by a rack-and-pinion mechanism including the pinion gear 107 and the rack 108.

By the rotation of the rotating table 103, three of the 2 carrier tapes T1, T2, and the splicing tape 30 are sandwiched between the pressing plate 103a and the first elevating table 91 and connected to each other.

The barrel cam 110 is supported by the apparatus main body 21 so as to be rotatable about an axis parallel to the turning center of the turning table 103, and is rotated at a low speed in a constant direction by a drive motor not shown. On both surfaces of the barrel cam 110, 2

cam grooves

110a, 110b, 110c, and 110d are formed in a ring shape in the circumferential direction.

A first follower roller, not shown, pivotally supported on the leg portion 92 of the first raising/lowering table 91 is engaged with the first cam groove 110 a. A second follower roller, not shown, pivotally supported on the movable base 96 coupled to the platen 97 engages with the second cam groove 110 b. A third follower roller, not shown, pivotally supported by the leg portion 102 of the second elevating table 101 is engaged with the third cam groove 110 c. A fourth follower roller, not shown, pivotally supported by a coupling member 112 coupled to the movable table 109 engages with the fourth cam groove 110 d.

Accordingly, when the barrel cam 110 rotates, the respective lifting and lowering movements of the first and second lifting and lowering

stages

91 and 101, the forward and backward movement of the pressure plate 97, and the revolving stage 103 are performed in conjunction with each other via the first to fourth follower rollers engaged with the first to fourth cam grooves 110a to 110d, respectively, and the first and second lifting and lowering

stages

91 and 101, the pressure plate 97, and the revolving stage 103 are returned to the original positions by 1 rotation of the barrel cam 110.

As shown in fig. 21, the splicing device 20 is provided with a closing holding device 24 that holds the lid 22 in a closed state during the splicing operation. The closure retention device 24 mainly comprises: a solenoid 25 provided in the apparatus main body 21 and capable of vertically operating an operating rod 25 a; a hook 27 rotatably supported by the apparatus main body 21 about a support shaft 26 and rotated by the solenoid 25; and an engaging pin 28 provided to the lid 22 so as to protrude downward and engaged with and disengaged from the hook 27.

An opening spring 29 for biasing the cover 22 in an opening direction is provided between the apparatus main body 21 and the cover 22, and when the engagement of the hook 27 and the engagement pin 28 is released, the cover 22 is automatically opened by the opening spring 29. The opening spring 29 constitutes an opening device that operates the lid 22 in the opening direction when the closure holding device 24 is released.

Although not shown, a claw is provided on the cover 22, and a closing confirmation sensor operated by the claw is provided on the apparatus main body 21. The closing confirmation sensor operates by a click when the cover 22 is closed, and confirms the closing of the cover 22 based on an on signal of the closing confirmation sensor.

When the operator turns on the closing confirmation sensor by closing the lid 22 and the click, the operating lever 25a of the solenoid 25 is operated in the upward direction of fig. 21 based on the on signal, and the hook 27 is rotated to engage with the engaging pin 28. Thereby, the lid 22 is held in the closed state by the closing holding device 24.

When the 2 carrier tapes T1 and T2 are connected to each other by the splicing tape 30 and a connection completion signal is sent from the control device 59, the operating rod 25a of the solenoid 25 operates downward in fig. 21. Thereby, the hook 27 is rotated to release the engagement with the engagement pin 28, and the lid 22 is automatically opened by the urging force of the opening operation device (opening spring) 29.

A lifting device 120 (see fig. 22) for lifting the first and second carrier tapes T1 and T2 connected by the splicing tape 30 in conjunction with the opening of the lid 22 is integrally provided on the inner surface (lower surface) of the lid 22. The splicing tape 30 bonded to the protective tape 31 can be reliably separated from the protective tape 31 by the lifting device 120.

As shown in fig. 22 and 23, the lifting device 120 includes a support member 121 fixed to a mounting portion 22a provided on the inner surface of the cover 22, and a plate-like lifting arm 122 extending in the longitudinal direction of the carrier tapes T1 and T2 is fixed to the front end portion of the support member 121. Both ends of the lift arm 122 are bent to form a pair of

hooks

123, 124 having different lengths with a space therebetween in the longitudinal direction of the carrier tapes T1, T2.

The

hooks

123 and 124 are formed with

support portions

123a and 124a, respectively, which lift the first and second carrier tapes T1 and T2 connected by the splicing tape 30 from below at positions close to both ends of the protective tape 31 (splicing tape 30). The

support portions

123a, 124a of the pair of

hooks

123, 124 are configured to be positioned below extension lines of the

conveyance paths

60a, 60b of the carrier tapes T1, T2 when the lid 22 is closed, as shown by solid lines in fig. 22, and to be positioned above extension lines of the

conveyance paths

60a, 60b when the lid 22 is opened, as shown by two-dot chain lines in fig. 22.

Thus, when the cover 22 is opened from the closed state, the lift arm 122 rotates around the pivot shaft 23 integrally with the cover 22, and the

support portions

123a and 124a of the pair of

hooks

123 and 124 cross the first and second carrier tapes T1 and T2 connected by the splicing tape 30, whereby the carrier tapes T1 and T2 are caught by the

support portions

123a and 124a and lifted, and the splicing tape 30 is peeled from the protective tape 31.

At this time, since the

support portions

123a and 124a of the pair of

hooks

123 and 124 are inclined, the carrier tapes T1 and T2 are gradually lifted from the back side in the width direction of the carrier tape T2 side, and the splicing tape 30 is gradually peeled off from one end (back side) in the width direction of the carrier tape T2 side. Therefore, when the splicing tape 30 is peeled off from the protective tape 31, the splicing tape 30 is not peeled off from the carrier tapes T1 and T2, and the splicing tape 30 can be connected to the carrier tapes T1 and T2 with high accuracy.

Next, the operation of the splicing apparatus 20 according to the above-described embodiment will be described. When the remaining amount of the components e held by the first carrier tape T1 wound around the reel 12 mounted on the tape feeder 10 is reduced, a splicing process is performed in which the leading end portion of the second carrier tape T2 wound around another reel containing the same kind of components e is connected to the leading end portion of the first carrier tape T1 by the splicing tape 30. The supply of the components from the tape feeder 10 is continued by supplying the components by the splicing.

In the above-described splicing, so-called splice verification is generally performed to check whether or not the carrier tape containing the correct component is connected. The splice verification reads the barcode attached to the used reel by a barcode reader, and transmits the serial ID of the components housed in the used reel to a management computer. Next, the barcode attached to the new reel is read by the barcode reader, and the serial ID of the component accommodated in the new reel is transmitted to the management computer.

Since the data relating to the components is stored in the database of the management computer for each serial ID, it is possible to check whether or not the components stored in the 2 carrier tapes T1 and T2 are the same type of component by the read serial ID. If the elements are different, a check error is displayed on the operation panel to inform the operator, and based on this, the operator performs the splicing again.

When such splice verification is completed, the respective ends of the 2 carrier tapes T1 and T2 are cut by scissors. At this time, an empty cavity portion having no component housed therein is generally provided at an end of each of the carrier tapes T1 and T2 by about several tens mm, and thus the portion is cut by an operator. In this case, as will be understood from the description below, the cut surface is not a mating surface of the 2 carrier tapes T1 and T2, and therefore, accuracy is not particularly required.

Normally, when the cover 22 is closed and the power is turned on by the operator in this state, the controller 59 resets the

stepping motors

62a and 62b to the home positions based on the detection signals from the first and second belt

gear tooth detectors

63a and 63 b. In this state, the control device 59 detects whether or not the leading end portions of the first and second tapes T2 are inserted from the first and

second tape inlets

84a, 84b based on the detection signals from the first and second

tape detecting devices

64a, 64 b. When the insertion of the distal end portions of the first and second tapes T2 is detected, the stepping

motors

62a and 62b are activated to rotate the first and second tape guide gears 61a and 61b and move the movable members 77a and 77b of the first and second take-in

members

75a and 75b in the upward direction.

Next, the controller 59 detects the first chambers Ct1 and Ct2 and the second chambers Ct1 and Ct2 in which the elements e1 and e2 of the first and second bands T1 and T2 are empty in sequence from the first and

second band detectors

64a and 64b based on the detection signals, and calculates the pitch Pc between the chambers Ct1 and Ct2 based on the detection of the first and second chambers Ct1 and Ct 2.

Next, the controller 59 calculates the cut positions Q1 and Q2 of the first and second tapes T1 and T2 based on the distance Pc between the chambers Ct1 and Ct2 and the distances D1 and D2 between the known detection positions Ld1 and Ld2 and the cut positions Lc1 and Lc2 (see fig. 4). As shown in fig. 13, the first and second tapes T1 and T2 are moved by distances D1 and D2 to take in the unnecessary portions Tf1 and Tf2 into the first and second taking-in

members

75a and 75b, and the cut portions Q1 and Q2 are conveyed and positioned at the cut positions Lc1 and Lc 2.

When the conveyance positioning of the first and second carrier tapes T1, T2 is completed in this way, the controller 59 lowers the

cutters

68a, 68b together with the

pressing members

72a, 72b, respectively, and presses and fixes the vicinities of the cutting positions Q1, Q2 of the first and second carrier tapes T1, T2 positioned at the cutting positions Lc1, Lc2 by the

pressing members

72a, 72 b. Next, the

cutters

68a and 68b are lowered to cut the cutting portions Q1 and Q2 of the first and second carrier tapes T1 and T2, respectively. The unnecessary portions Tf1 and Tf2 of the first and second carrier tapes T1 and T2 that have been cut are guided to the

passages

82a and 82b of the receiving

members

75a and 75b and discarded.

When the first and second carrier tapes T1 and T2 are cut by the

cutters

68a and 68b, the controller 59 moves the take-in

members

75a and 75b downward. Then, the stepping

motors

62a and 62b rotate the tape gears 61a and 61b, respectively, to move the first and second carrier tapes T1 and T2 by the known distances D3 and D4 between the cutting positions Lc1 and Lc2 and the splicing position LS, respectively, to transport and position the cutting positions Q1 and Q2 of the first and second carrier tapes T1 and T2 at the splicing position LS. Thereby, the feed holes Hc1 and Hc2 of the first and second carrier tapes T1 and T2 are positioned at positions engageable with the first positioning pins 93 and 94 of the connecting device 58 provided at the splicing position LS.

The first and

second belt conveyors

50 and 51 and the like described above constitute positioning means for positioning the first and second carrier tapes T1 and T2 at the splicing position LS where the positioning pins 93 and 94 engage with the feed holes Hc1 and Hc2 of the first and second carrier tapes T1 and T2, respectively.

Thus, the leading ends of the first and second carrier tapes T1, T2 inserted from the first and

second tape inlets

84a, 84b are positioned without causing a pitch deviation at the splicing position LS.

On the other hand, the 3-layer structure of the backing paper 32, the splicing tape 30, and the protective tape 31 wound around the supply reel 33 is pulled out from the supply reel 33, and the backing paper 32 is peeled off and fed out by the backing paper feeding device 35. The protective tape 31 to which the splicing tapes 30 are attached is sent out by the protective tape conveying device 36, and the splicing tapes 30 of 1 set for the front surface and the back surface are conveyed to the splicing position LS.

The splicing tape 30b for the back surface is conveyed to the position detected by the tape detection sensor 48 by the stepping motor 47 of the protective tape conveying device 36, and is further conveyed from the position by a certain distance, whereby the splicing tapes 30 of the group 1 for the front surface and the back surface are fed to the splicing position LS, and are positioned at positions where the positioning holes 30b1 formed in the splicing tape 30b for the back surface can be engaged with the first positioning pins 93, 94 of the connecting device 58 provided at the splicing position LS (refer to fig. 24).

When the splicing tape 30 is positioned at the splicing position LS, if the first and second carrier tapes T1 and T2 are not yet positioned at the splicing position LS, the first and second carrier tapes T1 and T2 wait until they are positioned at the splicing position LS.

When the first and second carrier tapes T1 and T2 and the splicing tape 30 are positioned at the splicing position LS, the cam drum 110 is rotated by a drive motor, not shown. By the rotation of the barrel cam 110, the first raising/lowering table 91 is first raised via the first follower roller, not shown, engaged with the first cam groove 110 a.

The first positioning pins 93 and 94 are engaged with the positioning holes 30b1 of the rear surface splicing tape 30b and the feed holes Hc of the 2 carrier tapes T1 and T2, respectively, by the elevation of the first elevation table 91. At this time, as shown in fig. 25(a), since the pressing plate 97 is interposed between the back surface splicing tape 30b and the carrier tapes T1 and T2, the carrier tapes T1 and T2 are not bonded to the back surface splicing tape 30 b. Thus, the positional relationship between the three 2 carrier tapes T1 and T2 and the back surface splicing tape 30b bonded to the back surface side thereof is maintained constant.

Next, the movable table 96 is moved in the horizontal direction via the second follower roller, not shown, engaged with the second cam groove 110b, and the pressure plate 97 interposed between the back surface splicing tape 30b and the carrier tapes T1, T2 is retracted relative to the first elevation table 91, so that the back surface splicing tape 30b and the carrier tapes T1, T2 are in a bondable state.

Next, the movable stand 109 is horizontally moved via an unillustrated third follower roller engaged with the third cam groove 110c, and the swing stand 103 is swung clockwise in fig. 19 by the rack-and-pinion mechanism (107, 108) by the horizontal movement of the movable stand 109. By the rotation of the rotating table 103, as shown in fig. 25(B), the protective tape 31 engaged with the second positioning pins 105 is bent, and the surface-use splicing tape 30a inverts the adhesive surface downward at a position above the carrier tapes T1 and T2. That is, the protective tape 31 is folded so as to sandwich the carrier tapes T1 and T2, the back surface-use splicing tape 30b is positioned on the back surface side of the carrier tapes T1 and T2, and the front surface-use splicing tape 30a is positioned on the front surface side of the carrier tapes T1 and T2. At this time, the motor of the protective tape feeding device 36 rotates in the reverse direction to impart slack to the protective tape 31 and allow the protective tape 31 to be bent.

Next, the second elevating table 101 is lowered via an unillustrated fourth follower roller engaged with the fourth cam groove 110 d. When the second elevating table 101 is lowered, as shown in fig. 25(C), the second positioning pins 105 engage with the positioning holes 31b of the protective tape 31, the feeding holes Hc of the carrier tapes T1, T2, and the positioning holes 30b1 of the rear surface splicing tape 30b from the rear side of the protective tape 31.

Further, by the lowering of the second elevating table 101, the folded protective tape 31 is pressed between the pressing plate 103a of the revolving table 103 and the first elevating table 91 in a state where the tapes T1 and T2 are sandwiched therebetween. By this pressing, the back surface-use splicing tape 30b joined to the protective tape 31 is bonded so as to straddle the back surfaces of the carrier tapes T1 and T2, the front surface-use splicing tape 30a is bonded so as to straddle the top seal tapes Tt bonded to the front surfaces of the carrier tapes T1 and T2, and the tip end portion of the first carrier tape T1 and the start end portion of the second carrier tape T2 are connected to each other. The above-mentioned state of compaction lasts for a certain time (several seconds).

The splicing tape 30 connects the 2 carrier tapes T1, T2 to the

splicing tapes

30a, 30b in a state where the relative deviation between the carrier tapes T1, T2 is restricted by the first and second positioning pins 93, 94, 105, and therefore, the 2 carrier tapes T1, T2 can be accurately connected without causing a gap deviation.

The splicing tape 30 is connected to the 2 carrier tapes T1 and T2 by rotating the cam drum 110 by approximately 180 degrees, and the components are returned to the original positions by the reverse operation of the rotation of the cam drum by the remaining 180 degrees.

That is, first, the second elevating table 101 is raised, the revolving table 103 is raised with respect to the first elevating table 91, the pressing of the bent protective tape 31 is released, and the second positioning pins 105 are disengaged from the positioning holes 30b1 of the back surface-use splicing tape 30b and the feeding holes Hc of the 2 carrier tapes T1 and T2.

Next, the turning table 103 is turned counterclockwise in fig. 19 via the rack and pinion mechanism (108, 107), and the motor of the protective tape conveying device 36 is rotated in the forward direction, and the slack of the protective tape 31 is removed.

Then, the pressing plate 97 advances, and the first lifter base 91 descends, and the first positioning pins 93 and 94 are disengaged from the positioning holes 30b1 of the splicing tape 30b for back surface and the respective feed holes Hc of the 2 carrier tapes T1 and T2. On the other hand, the motor is driven in the interleaving paper conveyance device 35 to apply tension to the interleaving paper 32 and peel the interleaving paper 32 by a required amount. Thus, the connection of the tail end portion of the first carrier tape T1 and the start end portion of the second carrier tape T2 is completed.

In this way, when the 2 carrier tapes T1 and T2 are connected to each other by the splicing tape 30, a connection completion signal is sent from the control device 59. Based on the above-described connection completion signal, the stepping motor 47 of the protective tape conveying apparatus 36 is restricted from rotating by the rotation restricting unit 47a, thereby preventing lifting of one end side of the protective tape 31, and by restricting rotation of the supply reel 33 by the supporting body 38, lifting of the other end side of the protective tape 31 can be prevented.

Next, the solenoid 25 of the splicing device 20 operates to move the operating rod 25a downward, and the hook 27 rotates clockwise in fig. 21 about the support shaft 26. Thereby, the engagement between the hook 27 and the engagement pin 28 is released, and the lid 22 is automatically opened by being rotated about the pivot shaft 23 by the biasing force of the spring 29.

At this time, the carrier tapes T1 and T2 connected by the splicing tape 30 are lifted upward from the T2 side by the

support portions

123a and 124a of the pair of

hooks

123 and 124 of the lift arm 122 provided on the lid body 22, and the splicing tape 30 adhered to the protective tape 31 is separated from the protective tape 31. In this case, since the

support portions

123a and 124a are provided with a tilt, the carrier tapes T1 and T2 are lifted from one end side (back side) in the width direction of the T2 side by the tilt, and the splicing tape 30 is gradually peeled off from the end portion with respect to the protective tape 31.

Since the rotation restricting unit 47a and the support 38 prevent the protective tape 31 from being lifted, the protective tape 31 is reliably peeled off from the protective tape 31 when the carrier tapes T1 and T2 are lifted by the lifting arm 122.

Thus, the splicing tape 30 is reliably peeled from the protective tape 31, and the splicing tape 30 connecting the carrier tapes T1 and T2 is not peeled from the carrier tapes T1 and T2.

The carrier tapes T1 and T2 lifted by the lifting arm 122 are easily taken out from the splicing device 20 by the worker. Then, the tape reel 12 on which the second carrier tape T2 is wound is set in the tape feeder 10, and the splicing process is completed. Thus, components are supplied to the tape feeder 10, and the component mounting operation is continued without stopping the machine in the component mounting machine.

When the cover 22 is closed by the operator to splice another carrier tape, a closing confirmation sensor, not shown, is turned on by a claw fixed to the cover 22. The solenoid 25 operates based on the on signal of the closing confirmation sensor, and the operating rod 25a moves upward. As a result, the hook 27 rotates counterclockwise in fig. 21 about the support shaft 26, and engages with the engagement pin 28 fixed to the lid 22. At the same time, an unillustrated motion confirmation sensor is turned on by an unillustrated pawl attached to the hook 27. When both of the closing confirmation sensor and the operation confirmation sensor are turned on, the splicing device 20 can be automatically operated.

Since the lid 22 cannot be opened by an external force when the lid 22 is closed in this way, an operator can be prevented from touching the operating portion in the splicing device 20 during the automatic operation, and safety can be ensured. Further, since the cover 22 is automatically opened when the splicing work is completed, workability can be improved.

According to the above-described embodiment, since the spliced carrier tapes T1 and T2 can be always lifted in a constant state by the lifting device 120, the splicing tapes 30 adhered to the carrier tapes T1 and T2 are not peeled off, and the spliced carrier tapes T1 and T2 can be easily taken out from the splicing device 20.

Further, since the lifting device 120 is provided in the openable and closable lid 22, the lifting device 120 can be operated in conjunction with the opening of the lid 22, and the structure of the lifting device 120 can be simplified.

According to the above-described embodiment, when the cover 22 is closed to splice the carrier tapes T1 and T2, the cover 22 is held in the closed state by the closing holding device 24, and therefore, an operator can be prevented from touching the operating portion in the splicing device 20 during operation, and safety can be ensured. Further, when the splicing is completed, the cover 22 can be automatically opened by the opening operation device (opening spring) 29, and therefore the spliced carrier tapes T1 and T2 can be easily and quickly taken out.

According to the above-described embodiment, the carrier tapes T1 and T2 connected by the splicing tape 30 can be lifted from the second carrier tape side by the pair of

hooks

123 and 124 having different lengths of the lifting device 120, and therefore the splicing tape 30 can be peeled off stably from the protective tape 31.

According to the above-described embodiment, since the pair of

hooks

123 and 124 have the

inclined support portions

123a and 124a, the splicing tape 30 can be gradually peeled off from the protective tape 31 at one end side in the width direction, and the splicing tape 30 can be smoothly peeled off from the protective tape 31.

In the above-described embodiment, the example was described in which the hook 123 of the pair of

hooks

123, 124 is formed shorter than the hook 124 and the second carrier tape T2 is lifted first in conjunction with the opening of the lid 22, but the first carrier tape T1 may be lifted first by reversing the lengths of the hooks.

In the above-described embodiment, the example in which the lifting device 120 is provided in the cover 22 and the first and second carrier tapes T1, T2 are lifted in conjunction with the opening of the cover 22 has been described, but the lifting device 120 may be provided in, for example, the apparatus main body 21 and operated separately from the cover 22.

In the above-described embodiment, the 3-layer structure of the splicing tape 30, the protective tape 31, and the interleaving paper 32 has been described, but the interleaving paper 32 may be removed to have a 2-layer structure of the splicing tape 30 and the protective tape 31.

In the above-described embodiment, the example of splicing 2 carrier tapes T1 and T2 formed of a paper tape having a flat front surface and a flat back surface has been described, but splicing can be performed in a configuration such as an embossed tape in which cavities are projected to the back surface side to be uneven.

The positioning devices (first and second tape conveyors) 50 and 51 for positioning the first and second carrier tapes T1 and T2 at the splicing position LS, the protective tape conveyor 36 for conveying the protective tape 31 to which the

splicing tapes

30a and 30b are attached, and the connecting device 58 for connecting the

splicing tapes

30a and 30b to the first and second carrier tapes T1 and T2 at the splicing position LS merely illustrate exemplary configurations preferred for carrying out the present invention and are not limited to the configurations described in the embodiments.

As described above, the present invention can take various forms without departing from the scope of the present invention as set forth in the claims.
