  The present invention relates to a splicing device.

  2. Description of the Related Art Generally, in an electronic component mounting machine, a reel on which a carrier tape containing a plurality of electronic components (hereinafter, simply referred to as "components") is wound at a fixed interval is loaded into a tape feeder, and a feed tape is formed on the carrier tape. By driving the sprockets that engage with the holes, the carrier tape is sent out by a fixed amount and components are sequentially supplied to the component supply position, and these components are sucked by the suction nozzle and mounted on the substrate.

  In this type of electronic component mounting machine, when the remaining amount of components stored on one reel decreases, the start end of the carrier tape wound on another reel storing the same type of components is reduced. The so-called splicing is performed by a splicing device, which is connected to the end of the resulting carrier tape by a splicing tape.

  For example, a splicing device described in Patent Literature 1 includes a first cutting device that cuts an unnecessary portion of a rear end portion of a carrier tape of a first reel and a second cutting device that cuts an unnecessary portion of a leading end portion of a carrier tape of a second reel. (2) a cutting device, and a joining device that joins the splicing tape across the rear end of the cut first reel carrier tape and the front end of the second reel carrier tape.

  The splicing device includes a splicing tape supply member having a three-layer structure including a base tape, a plurality of sets of splicing tapes attached to the base tape, and a top film covering the plurality of sets of splicing tapes. Then, the splicing device peels off the top film from the splicing tape supply member to be sent out, sends out the base tape, positions the splicing tape at the splicing position, and splices the two carrier tapes with the splicing tape.

Hereinafter, a schematic configuration of a splicing apparatus according to an embodiment of the present invention will be described with reference to the drawings. The detailed configuration of the splicing device will be described later. As shown in FIG. 1, the splicing device 20 is supported by the device main body 21 in a box shape and rotatably around a pivot 23 (see FIG. 2), and opens and closes the upper surface of the device main body 21. A lid 22 is provided, and a closing holding device 24 (see FIG. 2) for holding the lid 22 in a closed state during a splicing operation. The splicing device 20 can be moved between the tape feeders 10 (see FIG. 3) mounted on an unillustrated cart or the like and mounted on the electronic component mounting machine.

  The splicing device 20 replaces the end of the carrier tape T (see FIGS. 4 and 5) wound around the current reel 12 (see FIG. 3) mounted on the tape feeder 10 in the electronic component mounting machine. This is a device for automatically connecting to the start end of the carrier tape T wound around 12.

  That is, the splicing device 20 abuts the carrier tape T of the current reel 12 and the carrier tape T of the next reel 12 inserted from both sides of the device main body 21 at the center of the device main body 21, and the splicing tape supply member TT (FIG. 6). The lid 22 is manually closed at the time of splicing, and is automatically opened at the time of removing the carrier tape T after the splicing.

  As shown in FIG. 2, the closing and holding device 24 is installed on the device main body 21, and a solenoid 25 that can operate an operating rod 25 a in a vertical direction and supports the device main body 21 so as to be rotatable around a support shaft 26. The hook 27 is mainly constituted by a hook 27 rotated by a solenoid 25 and an engagement pin 28 provided to protrude downward from the lid 22 and engageable with the hook 27 in a detachable manner.

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

  Although not shown, a dog is provided on the lid 22, and a closing confirmation sensor operated by the dog is provided on the apparatus main body 21. The closing confirmation sensor is operated by the dog when the lid 22 is closed, and it is confirmed that the lid 22 is closed based on the ON signal of the closing confirmation sensor.

  Then, when the lid 22 is closed by the operator and the closing confirmation sensor is turned on by the dog, based on the ON signal, the operating rod 25a of the solenoid 25 is operated upward in FIG. It is rotated and engaged with the engagement pin 28. Thus, the lid 22 is held in the closed state by the closing holding device 24.

  When the two carrier tapes T1 and T2 are connected to each other by the splicing tape 30 and a connection completion signal is issued from the control device 59 (see FIG. 1), the operating rod 25a of the solenoid 25 is operated downward in FIG. You. As a result, 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 motor (not shown) is provided.

(3. Schematic configuration of carrier tape)
As shown in FIGS. 4 and 5, the carrier tape T is formed to be long and narrow with a predetermined width, and a large number of cavities Ct are arranged in the longitudinal direction at a constant pitch Pc. Each component e to be mounted is stored.

  The upper portion of the cavity Ct is open and is covered with a cover tape Tt attached to the surface of the carrier tape T. At one end in the width direction of the carrier tape T, perforations Hc are formed at the same pitch interval Pc as the cavity Ct or at a pitch interval 2Pc twice as large as the cavity Ct. Placed in a relationship.

  Note that the carrier tape T used in the electronic component mounting machine is composed of a plurality of types in which the pitch intervals of the cavities Ct are different from each other. Can be Therefore, by recognizing the pitch intervals of the cavities Ct by image processing or the like, it is possible to know which type of carrier tape T is used. Then, based on this, the position of the feed hole Hc of the carrier tape T can be recognized, and the cutting position of the carrier tape T at the time of splicing described later can be determined.

(4. Schematic configuration of the splicing tape supply member)
As shown in FIG. 6, the splicing tape supply member TT has a three-layer structure including a splicing tape 30, a base tape 31, and a top film 32. The splicing tape 30 is composed of a pair of splicing tapes 30a and 30b for the front surface and the back surface, which are adhered to both surfaces across two carrier tapes T on the upper surface of the continuous base tape 31.

  In addition, the adhesive force between the top film 32 and the base tape 31 adhered to both surfaces of the splicing tape 30 is stronger than the adhesive force to the base tape 31, and even if the top film 32 is peeled off from the splicing tape 30, Are not peeled off from the base tape 31. However, when the carrier tape T is adhered to the adhesive surface of the splicing tape 30 from which the top film 32 has been peeled off, the adhesive strength is stronger than the adhesive strength to the base tape 31, and the base tape 31 is peeled off from the splicing tape 30. Making it easier.

  The width dimension of the base tape 31 is larger than the width dimension of the top film 32, and both ends in the width direction of the base tape 31 protrude from both ends in the width direction of the top film 32. On the other hand, the width direction dimension of the splicing tape 30 is equal to the width direction dimension of the top film 32, and the splicing tape 30 is attached to the base tape 31 inside the feed hole 31a. A plurality of positioning holes 31b are formed in the base tape 31 at positions close to the front surface splicing tape 30a at the same pitch intervals as the feed holes Hc formed in the carrier tape T along the width direction of the base tape 31.

  In the splicing tape 30b for the back surface, a plurality of positioning holes 30b1 are formed along the width direction of the base tape 31 at the same pitch interval as the feed holes Hc formed in the carrier tape T through the base tape 31. The feed holes 31a and the positioning holes 31b formed in the base tape 31 are aligned with the formation of the positioning holes 30b1 in the back surface splicing tape 30b after the splicing tape 30 is attached to the predetermined position on the base tape 31.

Since the first and second cutting devices 54 and 55 are configured to drive the first and second cutting blade units 71a and 71b by one driving device 72, the first and second cutting devices are driven by two driving devices. As compared with the configuration in which the blade units 71a and 71b are driven respectively, the size can be reduced, and the increase in energy consumption and component cost can be suppressed.

  The first and second cutting blade units 71a and 71b hold first and second cutting blades 68a and 68b provided at the first and second cutting positions Lc1 and Lc2, and hold the first and second cutting blades 68a and 68b. The first and second holding members 69a and 69b are provided, and the first and second supporting members 70a and 70b support the first and second holding members 69a and 69b.

  As shown in FIG. 12, the first and second cutting blades 68a and 68b are formed in the same shape. As a result, the replacement cost of the first and second cutting blades 68a and 68b due to the wear of the cutting edges 68aa and 68ba of the first and second cutting blades 68a and 68b is symmetrical between the first and second cutting blades 68a and 68b. The cost can be reduced as compared with the case where it is formed in a shape.

  The cutting edges 68aa, 68ba of the first and second cutting blades 68a, 68b are formed in a shape inclined downward from the left end to the right end in FIG. 12 with respect to the horizontal direction. Accordingly, the resistance of the first and second cutting blades 68a and 68b at the time of cutting is reduced, so that the first and second carrier tapes T1 and T2 can be easily cut.

  As shown in FIG. 11, the first and second holding members 69a and 69b are formed in a quadrangular prism shape, and the cutting edges 68aa and 68ba of the first and second cutting blades 68a and 68b project downward from the lower surface. The first and second cutting blades 68a and 68b are held. The first and second holding members 69a and 69b have first and second support members so that both side surfaces can slide in the vertical direction and the upper surface can slide and contact with first and second cams 701a and 701b described later. It is supported by members 70a and 70b. On the lower surface side of the first and second holding members 69a and 69b, a pair of first and second pressing springs 73a and 73b whose lower ends are attached to both outer sides of the first and second transport paths 60a and 60b, respectively. The top is attached.

  The first and second support members 70a and 70b are formed in an arm shape, and rotatably supported by fitting rotation shafts for opening and closing the lid 22 into shaft holes 70ha and 70hb provided at one end. The first support member 70a and the second support member 70b are connected by a connection member 70 at a predetermined interval.

  The connecting member 70 is fixed to the lid 22, and the first and second support members 70a and 70b rotate around the shaft holes 70ha and 70hb with the lid 22 being opened and closed. The first and second support members 70a and 70b slidably support the first and second holding members 69a and 69b in vertically extending grooves 70da and 70db provided at the other ends.

  The first and second holding members 69a and 69b and the first and second support members 70a and 70b are symmetrical with respect to a plane passing through the splicing position LS at right angles to the feed direction of the first and second carrier tapes T1 and T2. It is composed of shaped members. Thereby, the first and second holding members 69a and 69b and the first and second support members 70a and 70b can be configured compactly.

  The driving device 72 includes first and second cams 701a and 701b that can slide on the first and second holding members 69a and 69b, and one gear motor 702 that is connected to the first and second cams 701a and 701b. A dog 703 (corresponding to the “detection device” of the present invention) rotatable with the rotation of the first and second cams 701a and 701b, and a dog detection device 704 (the “detection device” of the present invention) for detecting the rotation state of the dog 703 ).

  The first and second cams 701a and 701b are formed in a disk shape, and are eccentrically fitted to both ends of the cam shaft 705. The camshaft 705 is fixed to the first and second support members 70a and 70b such that the peripheral edges of the first and second cams 701a and 701b and the upper surfaces of the first and second holding members 69a and 69b can slide. The camshaft supporting members 706a and 706b are rotatably supported.

  Although the details will be described later, the first and second cams 701a and 701b are used when the distance between the horizontal plane passing through the eccentric center CC and the peripheral point in contact with the upper surfaces of the first and second holding members 69a and 69b becomes the shortest. , The first and second cutting blades 68a, 68b are located at the top dead center, and the distance between the horizontal plane passing through the eccentric center CC and the peripheral edge contacting the upper surfaces of the first and second holding members 69a, 69b is the longest. Then, the first and second cutting blades 68a, 68b are located at the bottom dead center.

  The second cam 701b is fitted on the camshaft 705 with a predetermined angle, for example, a phase shift of 30 degrees, with respect to the first cam 701a. Thereby, the time when the first cutting blade 68a cuts the first carrier tape T1 receiving the most cutting resistance and the time when the second cutting blade 68b cuts the second carrier tape T2 receiving the most cutting resistance can be shifted. Therefore, the rotational force of the camshaft 705 can be reduced, and the gearmotor 702 with a small output can be used. However, if there is a margin in the output of the gear motor 702, the first and second cams 701a and 701b may be fitted to the cam shaft 705 in the same phase.

  The gear motor 702 is a common motor for rotating the first and second cams 701a and 701b, and is fixed to a motor support member 707 fixed to the lid 22. The gear 708 rotatably fitted to the motor shaft of the gear motor 702 is engaged with the gear 709 rotatably fitted to the cam shaft 705 together with the cam shaft 705. Thus, the driving force of the gear motor 702 is transmitted to the camshaft 705 via the gears 708 and 709, and rotates the first and second cams 701a and 701b.

  The dog 703 is formed in a disk shape, and is rotatably fitted to the camshaft 705 together with the camshaft 705. The dog detection device 704 is fixed to the lid 22 so as to sandwich both side surfaces of the dog 703 at intervals. The dog detection device 704 detects the origin mark m attached to the side surface of the dog 703 by, for example, reflected light. The origin mark m, when detected by the dog detection device 704, is set to indicate, for example, that the first cutting blade 68a is located at the top dead center. Thereby, the first and second carrier tapes T1 and T2 can be cut with high precision.

  The first and second capturing devices 56 and 57 capture first and second unnecessary portions Tf1 and Tf2 of the first and second carrier tapes T1 and T2, respectively. That is, the first carrier tape T1 (the second carrier tape T2) in which the empty first cavities Ct1 (the second cavities Ct2) after the cutting are continuous becomes the first and second unnecessary portions Tf1 (the second unnecessary portions Tf2). (2) Captured by the capture devices 56 and 57 and discarded.

  As shown in FIG. 9, the first and second capturing devices 56 and 57 are provided between the first and second cutting positions Lc1 and Lc2 and the splicing position LS, and include the first and second fixing members 78a and 78a. First and second capturing members 75a and 75b rotatably supported by 78b, and first and second capturing member rotating devices 76a and 76b for rotating the first and second capturing members 75a and 75b. 76b and the like.

  The first and second take-up members 75a and 75b have first and second unnecessary portions Tf1 and Tf2 of the first and second carrier tapes T1 and T2 conveyed on the first and second conveyance paths 60a and 60b.

  When the first and second unnecessary portions Tf1 and Tf2 are taken in, the first and second taking members 75a and 75b are held at the original positions indicated by the dashed lines in FIG. When the first and second carrier tapes T1 and T2 are transported to the splicing position LS, as shown by the solid lines in FIG. 20, the first and second take-up member rotating devices 76a and 76b rotate by a predetermined angle. The first and second movable transfer paths 79a and 79b formed on the first and second take-in members 75a and 75b are aligned with the first and second transfer paths 60a and 60b.

  As shown in FIG. 8, the supply reel holding unit 38 is attached to the apparatus main body 21, and rotatably supports the supply reel 33 around which the splicing tape supply member TT is wound in a roll shape. The supply reel holding portion 38 is pressed against the supply reel 33 by a predetermined frictional force due to a spring force, and the supply reel holding portion 38 restricts the rotation of the supply reel 33 with respect to the supply reel holding portion 38. When the base tape 31 is pulled by the acting force that overcomes the frictional force, the supply reel 33 can be rotated with respect to the supply reel holding portion 38.

  The top film peeling device 35 includes a film peeling member 351 and a top film transport device 352. As shown in FIG. 13, the film peeling member 351 is formed in a plate shape, and is arranged before the splicing position LS in the transport direction of the splicing tape supply member TT.

Is engaged with the engaging teeth 46a of the feed sprocket 46.

  The stepping motor 47 is connected to the feed sprocket 46, and feeds a unit amount of the base tape 31 engaged with the engagement teeth 46a by driving one pitch. The stepping motor 47 is returned to the home position by turning on the power, and is positioned so that the engaging teeth 46a of the feed sprocket 46 are always positioned at the top.

  Further, the rotation of the stepping motor 47 can be appropriately restricted by, for example, a rotation restricting means 47a such as a servo lock device or by applying an excitation. When the first and second carrier tapes T1 and T2 for which splicing has been completed are to be taken out of the splicing device 20 by the frictional action of the supply reel holding portion 38 and the rotation restricting means 47a, the movement of both ends of the base tape 31 is prevented. A restricting device for restricting the lifting of the base tape 31 is configured.

  As shown in FIG. 9, the joining device 58 is provided between the first cutting device 54 and the second cutting device 55. The splicing device 58 detects the splicing tapes 30a and 30b installed at a position separated from the splicing position LS by a certain distance before the splicing position LS below the base tape 31 fed from the supply reel 33.

On the first elevating table 91, positioning holes 30b1 formed in the splicing tape 30b and the first and second carriers are formed on both sides around the joining position (butting position) of the first and second carrier tapes T1 and T2. Two first positioning pins 93 and 94, each of which can be engaged with each of the feed holes Hc of the tapes T1 and T2, protrude along the feed direction of the first and second carrier tapes T1 and T2.

  The pitch of each of the two sets of first positioning pins 93 and 94 is set to twice the pitch Ph of the feed holes Hc of the first and second carrier tapes T1 and T2. Further, a pin hole 95 is formed in the first elevating table 91 between each of the first positioning pins 93 and 94, and a second positioning pin 105 of the swivel table 103, which will be described later, enters the pin hole 95. it can.

The holding plate 97 is attached at the upper position of. A U-shaped groove 98 capable of accommodating the first positioning pins 93 and 94 is formed at the tip of the holding plate 97, and the holding plate 97 has a recessed end where the groove 98 is separated from the first positioning pins 93 and 94. The groove 98 can be advanced and retracted between an advanced end position in which the first positioning pins 93 and 94 are accommodated.

  Further, a leg 102 of the second elevating table 101 is supported by the apparatus main body 21 so as to be able to move up and down. On the second lift table 101, both ends of a turntable 103 are supported so as to be able to turn 180 degrees around a pivot shaft 104 parallel to the longitudinal direction of the first and second carrier tapes T1 and T2.

  The swivel table 103 is provided with a pressing plate 103a at a position offset from the center of rotation, and the pressing plate 103a is provided with a plurality of second positioning pins 105 and pin holes 106. 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 lifting platform 91, and can protrude into the pin holes 95 provided on the first lifting platform 91.

  Further, 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 enter. The second positioning pin 105 is engaged with the feed hole Hc of the first and second carrier tapes T1 and T2 positioned at the splicing position LS and the positioning hole 30b1 of the splicing tape 30b by the 180 ° rotation of the swivel table 103, The positional relationship between the first and second carrier tapes T1, T2 and the splicing tape 30 connecting them is kept constant.

  A pinion 107 is attached to a pivot shaft 104 of the swivel table 103, and a rack 108 that meshes with the pinion 107 can move in a horizontal direction orthogonal to the transport direction of the first and second carrier tapes T1 and T2. Attached to As a result, when the movable base 109 is moved, the swivel base 103 is swung by the rack and pinion mechanism including the pinion 107 and the rack 108. Due to the rotation of the swivel table 103, the first and second carrier tapes T1 and T2 and the splicing tape 30 are sandwiched between the pressing plate 103a and the first elevating table 91, and are connected to each other.

  The cam drum 110 is rotatably supported by the apparatus main body 21 around an axis parallel to the center of rotation of the swivel table 103, and is rotated at a low speed in a certain direction by a drive motor (not shown). On both surfaces of the cam drum 110, two inner and outer cam grooves 110a, 110b, 110c, 110d are respectively formed in a circumferential direction endlessly.

The two elevating tables 91 and 101, the holding plate 97 and the swivel table 103 are returned to their original positions.

(6. Operation of the splicing device)
Next, the operation of the splicing device 20 according to the above-described embodiment will be described. When the remaining amount of the component e held on the first carrier tape T1 wound around the reel 12 attached to the tape feeder 10 becomes small, another component e of the same type is stored at the end of the first carrier tape T1. A splicing process of connecting the start end of the second carrier tape T2 wound around the reel with the splicing tape 30 is performed. Parts are replenished by such splicing, and the supply of parts from the tape feeder 10 can be continued.

  In such splicing, so-called splicing verification, which checks whether or not a carrier tape containing correct components is connected, is usually executed. The splicing verify reads the bar code attached to the old reel by a bar code reader and transmits the serial ID of the component accommodated in the old reel to the management computer. Next, the bar code attached to the new reel is read by a bar code reader, and the serial ID of the component accommodated in the new reel is transmitted to the management computer.

  Since the database of the management computer stores data on parts for each serial ID, it is determined whether the parts contained in the two carrier tapes T1 and T2 are of the same type based on the read serial ID. Can be collated. If it is an incorrect part, a collation error is displayed on the operation panel and notified to the operator, and based on this, the operator performs splicing again.

  When the splicing verification is completed, each end of the first and second carrier tapes T1 and T2 is cut with scissors. At this time, since an empty cavity portion in which no component is stored is provided at an end portion of each of the carrier tapes T1 and T2, which is usually several tens of mm, this portion is cut by an operator. In this case, the cut surface does not become the mating surface of the first and second carrier tapes T1 and T2, as will be apparent from the description to be described later.

  Normally, the lid 22 of the splicing device 20 is closed, and in this state, when the power is turned on by the operator, the control device 59 outputs the detection signals from the first and second sprocket tooth detecting devices 63a and 63b. , The stepping motors 62a and 62b are returned to their original positions. Further, as shown in FIG. 20, the control device 59 positions the first cutting blade 68a at the top dead center based on the detection signal from the dog detection device 704.

  In this state, the control device 59 sends the first and second carrier tapes T1 and T2 from the first and second tape entrances 84a and 84b based on the detection signals from the first and second tape detection devices 64a and 64b. Detects whether the tip has been inserted. When it is detected that the leading ends of the first and second carrier tapes T1 and T2 have been inserted, the stepping motors 62a and 62b are started, and the first and second sprockets 61a and 61b are rotated. The movable members 77a, 77b of the second intake members 75a, 75b are moved upward.

  Next, based on the detection signals from the first and second tape detecting devices 64a and 64b, the control device 59 controls the first cavities Ct1 and Ct2 where the components e1 and e2 of the first and second carrier tapes T1 and T2 are empty. And the second cavities Ct1 and Ct2 are sequentially detected, and the pitch Pc between the cavities Ct1 and Ct2 is calculated based on the detection of the first and second cavities Ct1 and Ct2.

  Next, as shown in FIG. 21, the control device 59 calculates the first pitch Pc between the cavities Ct1 and Ct2 and the distances D1 and D2 between the known detection positions Ld1 and Ld2 and the cutting positions Lc1 and Lc2. , The cut positions Q1, Q2 of the second carrier tapes T1, T2 are calculated. Then, the first and second carrier tapes T1 and T2 are moved by the distances D1 and D2 so that the unnecessary portions Tf1 and Tf2 are taken into the first and second take-up members 75a and 75b, and the cut portions Q1 and Q2 are cut. It is transported and positioned at Lc1 and Lc2.

  In this way, when the transport positioning of the first and second carrier tapes T1 and T2 is completed, as shown in FIG. 22, the control device 59 lowers the first and second cutting blades 68a and 68b, respectively, and 1. First and second cut portions Q1 and Q2 of the second carrier tapes T1 and T2 are cut, respectively.

  That is, as shown in FIGS. 24A and 24B, before the start of cutting, if the rotation angle of the cam shaft 705 is 0 degree, the cam peripheral point A of the first cam 701a contacts the upper surface of the first holding member 69a. The cam peripheral point D of the second cam 701b is in contact with the upper surface of the second holding member 69b. Therefore, the height of the lower end of the first cutting blade 68a is located at the height hmax of the top dead center, and the height of the lower end of the second cutting blade 68b is lower than the height hmax of the top dead center. It is located in ho.

  Then, the first cutting blade 68a starts to descend by the rotation of the first cam 701a, and the first cutting blade 68a rotates the rotation angle of the cam shaft 705 by θ degrees (<180 degrees) (the cam peripheral point B of the first cam 701a). Reaches the height hc of the first holding member 69a), cutting of the first cutting portion Q1 of the first carrier tape T1 is started.

  Then, the first cutting blade 68a reaches the height hmin of the bottom dead center at the rotation angle of the cam shaft 705 of 180 degrees (the cam peripheral point C of the first cam 701a contacts the upper surface of the first holding member 69a). At this time, the cutting of the first cutting portion Q1 of the first carrier tape T1 is completed and the ascending starts, and the rotation angle of the cam shaft 705 is 360 degrees (the cam peripheral point A of the first cam 701a is on the upper surface of the first holding member 69a. When the contact reaches the height hmax of the top dead center, the ascent stops. The raising and stopping of the first cutting blade 68a is performed by detecting the origin mark m of the dog 703 by the dog detecting device 704.

  On the other hand, the second cutting blade 68b rotates the second cam 701b at the same time as the first cam 701a so that the rotation angle of the cam shaft 705 is 30 degrees (the cam peripheral point E of the second cam 701b is the upper surface of the second holding member 69b). Once reached the height hmax of the top dead center, and then descends, and the second cutting blade 68b rotates the camshaft 705 at a rotational angle of θ + 30 degrees (the cam peripheral point F of the second cam 701b becomes the second holding member 69b). (Contact with the upper surface of the second carrier tape T2), the cutting of the second cutting portion Q2 of the second carrier tape T2 is started.

  Then, the second cutting blade 68b reaches the height hmin of the bottom dead center at the rotation angle of the cam shaft 705 of 210 degrees (the cam peripheral point G of the second cam 701b contacts the upper surface of the second holding member 69b). At this time, the cutting of the second cut portion Q2 of the second carrier tape T2 is completed and the ascending rotation starts, and the rotation angle of the cam shaft 705 is 360 degrees (the cam peripheral point D of the second cam 701b is on the upper surface of the second holding member 69b. (Contact), that is, when the height of the first cutting blade 68a is stopped. The cut unnecessary portions Tf1 and Tf2 of the first and second carrier tapes T1 and T2 are guided by the ducts 82a and 82b of the intake members 75a and 75b and discarded.

  When the first and second carrier tapes T1 and T2 are cut by the cutting blades 68a and 68b, as shown in FIG. 23, the control device 59 moves the capturing members 75a and 75b downward. Thereafter, the sprockets 61a and 61b are rotated by the stepping motors 62a and 62b, respectively, and the first and second carrier tapes T1 and T2 are moved by the known distances D3 and D4 between the cutting positions Lc1 and Lc2 and the splicing position LS. By moving them, the cut positions Q1, Q2 of the first and second carrier tapes T1, T2 are transported and positioned 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 where they can be engaged with the first positioning pins 93 and 94 of the joining device 58 provided at the splicing position LS. On the other hand, the splicing tape supply member TT wound on the supply reel 33 is sent out from the supply reel 33 by the stepping motor 47 of the splicing tape supply member transport device 36, and one set of the splicing tape 30 for the front side and the back side is formed. It is transported to the splicing position LS.

  Then, the splicing tape 30b for the back surface is once sent to a position detected by the tape detection sensor 48, and is sent a further fixed distance from the position, so that a pair of splicing tapes 30 for the front surface and the back surface is spliced. It is sent to the position LS. Then, as shown in FIG. 25, the positioning hole 30b1 formed in the back surface splicing tape 30b is positioned at a position where it can be engaged with the first positioning pins 93 and 94 of the joining device 58 provided at the splicing position LS. .

  Then, as shown in FIGS. 26A and 26B, the top film 32 is folded by the top film feeder 35 in a direction opposite to the feeding direction of the splicing tape supply member TT, and is peeled off. 351a.

  The top film transport device 352 stops sending the top film 32 when the top film 32 is sent out by a distance until the top film 32 comes into contact with the front end portion 351a of the film peeling member 351. According to this, the top film 32 is not peeled off after coming into contact with the plate-like end of the film peeling member 351, and only one set of the splicing tapes 30 is exposed and positioned at the splicing position LS. Is done.

  Then, at the splicing position LS, since only one set of the splicing tapes 30 of the plurality of sets of the splicing tapes 30 is peeled off and exposed, the adhesiveness of the splicing tapes 30 other than the one set is reduced. Can be suppressed. Further, since the peeling length of the top film 32 is short, the base tape 31 is not pulled by a strong force at the time of the peeling, and a decrease in the positioning accuracy of the splicing tape 30 at the splicing position LS can be suppressed.

  When the first and second carrier tapes T1 and T2 and the splicing tape 30 are positioned at the splicing positions LS, the stepping motor 47 of the splicing tape supply member transport device 36 is excited. That is, the splicing tape supply member transporting device 36 positions the splicing tape 30 at the splicing position LS and brings the splicing tape 30 into a stationary holding state.

  The supply reel holding unit 38 holds the supply reel 33 by applying a frictional force in a direction opposite to the rotation direction, so that the splicing tape supply member transport device 36 in the stationary holding state is used for splicing. The tape 30 can be joined with higher precision across the first carrier tape T1 and the second carrier tape T2.

  Then, the cam drum 110 is rotated by a drive motor (not shown). By the rotation of the cam drum 110, first, the first lifting table 91 is raised via the first follower roller engaged with the first cam groove 110a. The first positioning pins 93 and 94 are engaged with the positioning holes 30b1 of the back side splicing tape 30b and the respective feed holes Hc of the first and second carrier tapes T1 and T2 by the raising of the first lifting table 91.

  At this time, since the holding plate 97 is interposed between the back side splicing tape 30b and the first and second carrier tapes T1 and T2, as shown in FIG. The second carrier tapes T1 and T2 do not adhere. As a result, the positional relationship between the first and second carrier tapes T1 and T2 and the back splicing tape 30b adhered to the back surface of the first and second carrier tapes T2 is kept constant.

  Next, the movable table 96 is moved in the horizontal direction via the second follower roller engaged with the second cam groove 110b, and is interposed between the back side splicing tape 30b and the first and second carrier tapes T1 and T2. The pressed holding plate 97 is retracted with respect to the first elevating table 91, so that the back side splicing tape 30b and the first and second carrier tapes T1 and T2 can be bonded.

  Next, the movable table 109 is horizontally moved via the third follower roller engaged with the third cam groove 110c, and the horizontal movement of the movable table 109 causes the rack and pinion mechanism (107, 108) to pivot the turntable 103. Turn 19 clockwise. As shown in FIG. 27B, the base tape 31 engaged with the second positioning pin 105 is bent by the rotation of the swivel table 103, and the splicing tape 30a for the front surface is separated from the first and second carrier tapes T1 and T2. It is turned upside down with the adhesive side down.

  That is, the base tape 31 is bent so as to sandwich the first and second carrier tapes T1 and T2, and the first and second carrier tapes T1 and T2 are provided with the first and second backing splicing tapes 30b on the back side. The front surface splicing tape 30a is located on the front side of the carrier tapes T1 and T2. At this time, the motor of the splicing tape supply member conveying device 36 is rotated in the reverse direction, so that the base tape 31 is slackened and the base tape 31 is allowed to be bent.

  Subsequently, the second lift 101 is lowered via the fourth follower roller engaged with the fourth cam groove 110d. When the second lifting table 101 is lowered, as shown in FIG. 27C, the second positioning pins 105 move the positioning holes 31b of the base tape 31 and the first and second carrier tapes T1 and T2 from behind the base tape 31. It is engaged with the feed hole Hc and the positioning hole 30b1 of the back side splicing tape 30b.

  Further, by lowering the second elevator 101, the folded base tape 31 is held between the pressing plate 103a of the swivel 103 and the first elevator 91 while the first and second carrier tapes T1 and T2 are held therebetween. Pressed with. By this pressing, the back surface splicing tape 30b stuck to the base tape 31 is adhered so as to straddle the back surfaces of the first and second carrier tapes T1 and T2, and the front surface splicing tape 30a is attached to the first and second carrier tapes. It is adhered so as to straddle each cover tape Tt attached to the surface of the tapes T1 and T2, and the end of the first carrier tape T1 and the start of the second carrier tape T2 are connected to each other. This pressing state is maintained for a fixed time (several seconds).

  The connection of the first and second carrier tapes T1 and T2 by the splicing tape 30 is such that the first and second carrier tapes T1 and T2 and the splicing tape 30 are relatively positioned by the first positioning pins 93 and 94 and the second positioning pin 105. Since the first and second carrier tapes T1 and T2 can be accurately joined without causing a pitch shift because the shift is performed while restraining the shift.

  The joining of the first and second carrier tapes T1 and T2 by the above-described splicing tape 30 is achieved by substantially 180-degree rotation of the cam drum 110, and by the remaining 180-degree rotation, the respective members are operated in a reverse operation to the above. Is returned to the original position. That is, first, the second lift 101 is raised, the swivel 103 is raised with respect to the first lift 91, the pressing of the bent base tape 31 is released, and the second positioning pin 105 is It is detached from the positioning hole 30b1 of the splicing tape 30b and the respective feed holes Hc of the first and second carrier tapes T1 and T2.

  Subsequently, the turntable 103 is turned counterclockwise in FIG. 18 via the rack and pinion mechanism (108, 107), and the motor of the splicing tape supply member conveying device 36 is rotated forward to loosen the base tape 31. Is removed. Thereafter, the holding plate 97 is moved forward, and the first elevator 91 is lowered, and the first positioning pins 93 and 94 are moved to the positioning holes 30b1 of the back side splicing tape 30b and the first and second carrier tapes T1 and T2. It is separated from the feed hole Hc.

  On the other hand, in the top film feeder 35, a motor is driven to apply tension to the top film 32, and the top film 32 is peeled by a necessary amount. In this way, the joining of the end of the first carrier tape T1 and the start of the second carrier tape T2 is completed.

  When the first and second carrier tapes T1 and T2 are connected to each other by the splicing tape 30 in this way, the control device 59 issues a connection completion signal. On the basis of the connection completion signal, the solenoid 25 of the splicing device 20 is operated, the operating rod 25a is moved downward, and the hook 27 is rotated clockwise in FIG.

  As a result, the engagement between the hook 27 and the engagement pin 28 is released, and the lid 22 is rotated about the pivot 23 by the urging force of the spring 29, and is automatically opened. Thereafter, the reel 12 around which the second carrier tape T2 is wound is set on the tape feeder 10, and the splicing process is completed. As a result, the components are supplied to the tape feeder 10, and in the electronic component mounting machine, the component mounting work can be continued without stopping the machine.

(7. Another form of support for supply reel)
In the above-described embodiment, the supply reel 33 is rotatably supported by the supply reel holder 38 attached to the apparatus main body 21. However, as in the case of the supply reel holder 380 shown in FIG. Alternatively, a configuration may be adopted in which three inner springs of the supply reel 33 are pressed in the radial direction and supported by three leaf springs 382, 383, and 384 attached to the plate surface of the disk-shaped reel holder 381.

  In this case, when the reel holder 381 is attached to the apparatus main body 21 so as to be completely freely rotatable, splicing is performed by the feed inertia of the splicing tape supply member TT wound around the supply reel 33, the winding force of the top film 32, and the like. The splicing tape 30 at the position LS may be misaligned. For this reason, the reel holder 381 is provided with a wave washer 385 in order to give a weight and prevent the above-mentioned positional deviation.

And TT.

  Further, a holding section (supply reel holding section 38) for holding the splicing tape supply member TT, and the splicing tape supply member TT from the holding section 38 in a direction perpendicular to the feed direction of the first carrier tape T1 and the second carrier tape T2. The top film 32 is peeled from the base tape 31 of the splicing tape supply member TT conveyed from the holding unit 38 and the splicing tape supply member conveyance device 36 to be fed, and only one of the plurality of sets of the splicing tapes 30 is spliced. A top film peeling device 35 that is exposed at the splicing position LS and a bond that joins a pair of splicing tapes 30 that are positioned while being exposed at the splicing position LS across the first carrier tape T1 and the second carrier tape T2. Device 58; Provided.

  According to this, at the splicing position LS, only one set of the splicing tapes 30 out of the plurality of sets of the splicing tapes 30 is peeled off and exposed, so that the adhesiveness of the splicing tapes 30 other than the one set is reduced. Can be suppressed. Further, since the peeling length of the top film 32 is short, the base tape 31 is not pulled by a strong force at the time of the peeling, and a decrease in the positioning accuracy of the splicing tape 30 at the splicing position LS can be suppressed.

  In addition, the top film peeling device 35 is formed in a plate shape, is disposed before the splicing position LS in the transport direction of the splicing tape supply member TT, and connects the top film 32 to the splicing tape supply member TT at the plate-shaped end. The film peeling member 351 that folds the top film 32 from the base tape 31 in a direction opposite to the transport direction and the top film 32 that is folded back at the end of the film peeling member 351 transports the splicing tape supply member TT in the transport direction. And a top film transport device 352 for feeding in the opposite direction.

  The top film transport device 352 stops sending the top film 32 when the top film 32 is sent out by a distance until the top film 32 comes into contact with the front end portion 351a of the film peeling member 351. Thus, the top film 32 is not peeled off after coming into contact with the plate-like end of the film peeling member 351, and only one set of the splicing tapes 30 is exposed and positioned at the splicing position LS. .

  Further, the splicing tape supply member transporting device 36 positions the splicing tape 30 at the splicing position LS and keeps the splicing tape 30 in the stationary state, so that the splicing tape 30 can be placed with high accuracy across the first carrier tape T1 and the second carrier tape T2. Can be joined.

  Further, the holding portion 38 holds the splicing tape supply member TT wound in a reel shape rotatably and by applying a frictional force in a direction opposite to the rotation direction, so that the splicing tape in a stationary holding state is provided. The splicing tape 30 can be joined with higher precision across the first carrier tape T1 and the second carrier tape T2 in cooperation with the supply member transport device 36.
