The protective tape 31 to which the splicing tape 30 is applied is fed into the device main body 11 of the splicing device 10 in the direction of the arrow perpendicular to the guide rail 60 so as to cross the splicing position Ls.

  As shown in FIG. 6, the splicing tape 30 is a set of two splicing tapes 30 a that are bonded to the upper surface of a continuous protective tape 31 and to be bonded to both surfaces (front and back surfaces) of the two carrier tapes 100. , 30b are attached with a weak adhesive force at intervals in the longitudinal direction of the protective tape 31. The upper surfaces of the splicing tapes 30a and 30b form a pressure-sensitive adhesive surface having a strong adhesive force that is bonded to both surfaces of the two carrier tapes 100. A large number of two sets of splicing tapes 30 are arranged in the longitudinal direction of the protective tape 31 with a constant pitch interval Pd.

  The splicing tape 30b and the protective tape 31 of the splicing tape 30 have a positioning hole 30b1 for engaging a positioning pin described later, and the protective tape 31 is positioned for engaging a positioning pin described later. The hole 31b is formed in parallel with the positioning hole 30b1. In addition, feed holes 31a that engage with a tape feed sprocket (not shown) are formed at both ends of the protective tape 31 at regular pitch intervals.

  Below the protective tape 31, two detection sensors 48, 49 for detecting the splicing tapes 30a, 30b are arranged with a predetermined interval. Specifically, the two detection sensors 48 and 49 are provided for a pair of splicing tapes when the pair of splicing tapes (first splicing tape) 30 for the front surface and the back surface are positioned at the splicing position Ls. A position that is simultaneously turned on by the front splicing tape 30a of the tape (second splicing tape) 30 and the back splicing tape 30b of a set of splicing tapes (third splicing tape) that follows the tape splicing tape 30a. In other states, the two detection sensors 48 and 49 are not simultaneously turned on. As a result, the splicing tape 30 can be correctly positioned at the splicing position Ls.

  As shown in FIGS. 7 and 8, the tape connecting portion 15 that connects the two carrier tapes 100 by the splicing tapes 30 a and 30 b includes first and second tapes arranged at predetermined intervals in the longitudinal direction of the protective tape 31. The 2nd lifting platforms 111 and 112 are provided, and the 1st and 2nd lifting platforms 111 and 112 are supported by the apparatus main body 11 so that raising / lowering is possible. The second elevator 112 is supported on a turntable (not shown) and can turn 180 degrees in the direction of the arrow in FIG. On the first lifting platform 111, the splicing tape 30b and the positioning holes 30b1 formed in the protective tape 31 and the feed holes 100c of the two carrier tapes 100 are engageable on both sides of the splicing position Ls. Two first positioning pins 113 and 114 are provided along the conveying direction of the carrier tape 100.

  On the other hand, a plurality of second positioning pins 115 are provided between the first positioning pins 113 and 114 along the first positioning pins 113 and 114 in the second lifting platform 112 that can turn. The second positioning pin 115 is moved to the upper position of the first lifting platform 111 as shown in FIG. 9 by the turning of the second lifting platform 112. The first and second elevators 111 and 112 are provided with pin holes into which the second positioning pins 115 and the first positioning pins 113 and 114 can be inserted.

As a result, at the time of splicing, the positional relationship between the three carrier tapes 100 and the splicing tape 30 connecting the two carrier tapes 100 is kept constant.

  In the figure, reference numeral 117 denotes an advanceable / retractable plate interposed between the carrier tape 100 and the back surface splicing tape 30b. The plate 117 has the upper surface of the splicing tapes 30a, 30b conveyed to the splicing position Ls on the carrier tape 100. It is intended to prevent adhesion. The plate 117 is retracted from between the back surface splicing tape 30b and the carrier tape 100 immediately before the two carrier tapes 100 are connected by the splicing tapes 30a and 30b.

  In addition, about the structure of the tape connection part 15, since the thing of the structure described in the international publication 2013/157107 which concerns on this applicant's application can be employ | adopted, description is abbreviate | omitted about a detailed structure.

  Next, the splicing operation in the above embodiment will be described. For example, when the first carrier tape 100 (100x) having a small tape width is spliced, the splicing units 13 and 14 including the guide rails 60 corresponding to the tape width of the first carrier tape 100x are used as the apparatus main body. 11 is mounted in the mounting recess 11a. When the splicing units 13 and 14 are mounted in the mounting recess 11a of the apparatus main body 11, the connectors 87 and 88 are connected, and the splicing units 13 and 14 are prevented from being disconnected by the disconnection preventing device 90. Is held in a fixed positional relationship with respect to the apparatus main body 11.

  In this state, when the power of the splicing device 10 is turned on, the individual information stored in the storage members 85 respectively incorporated in the splicing units 13 and 14 is transmitted to the control unit 16 via the connectors 87 and 88. . The transmitted individual information is displayed on the display units 89a and 89b of the apparatus main body 11, and can be visually recognized by the operator.

  The control unit 16 recognizes whether the left and right splicing units 13 and 14 have the same kind of individual information corresponding to the carrier tape 100 having the same tape width. When the control unit 16 recognizes that the left and right splicing units 13 and 14 are of different types, it is displayed on the display of the control unit 16 that the attachment is incorrect, and the operator is notified. Thereby, the operator redoes the mounting of the splicing units 13 and 14. In the case of incorrect mounting, the carrier tape 100 may not be inserted into the tape insertion slot 84.

  When the remaining amount of the component Pa stored in the first carrier tape 100x having a small tape width mounted on the tape feeder (not shown) is exhausted (reduced), the same type of component Pa is formed at the end of the carrier tape 100. Splicing is performed to connect the starting end of another carrier tape 100 that accommodates. At the time of splicing, so-called splicing verification is performed to check whether the two carrier tapes 100 to be connected contain the same type of component Pa.

  After execution of splicing verification, the carrier tape 100 is inserted by the operator through the tape insertion openings 84 of the pair of splicing units 13 and 14. When the carrier tape 100 is inserted into the tape insertion slot 84, after the stepping motor 62 positions the sprocket 61 at the origin position, the pitch ½ of the pitch Ph of the feed hole 100c (the component storage portion 100a of the carrier tape 100). Intermittent drive at the minimum pitch). Thereby, the carrier tape 100 is conveyed along the guide rail 60 by the sprocket 61 rotated by the stepping motor 62.

  When the carrier tape 100 crosses the detection unit 53 disposed at the tape detection position Ld, the signal of the detection unit 53 changes and the signal is transmitted to the control unit 16. By transporting the carrier tape 100, as shown in FIG. 10A, the tape body portion between the component storage unit 100a and the component storage unit 100a passes through the tape detection position Ld. Here, the detection signal of the detection unit 53 made of a photosensor becomes “S1” (component-free signal) because the amount of transmitted light increases in the empty component storage portion 100a where there is no component Pa. In the part storage part 100a in which Pa is stored and in the tape main body part between the part storage parts 100a, the transmitted light amount decreases depending on the part Pa and the thickness of the tape, so "S2" (part presence signal) lower than "S1". It becomes.

  The control unit 16 inputs the component presence signal “S2” from the detection unit 53, and determines that the first component Pa is stored in the component storage unit 100a when it is detected twice consecutively. On the other hand, the control unit 16 determines the type of the carrier tape 100 based on the detection signal of the detection unit 53 and obtains the cut portion CU of each carrier tape 100.

  That is, since two or three empty component storage portions 100a that do not store the component Pa are provided at the end of the carrier tape 100, as shown in FIG. 10B, the detection signal “S1” of the detection unit 53 is provided. ”(No component signal) rise time t1 and rise time t2 of the next detection signal“ S1 ”, and the pulse of the stepping motor 62 required to drive the sprocket 61 between these time t1 and time t2. By counting the number (rotation angle), the pitch of the component storage unit 100a can be determined.

  Based on the discrimination of the pitch of the component storage unit 100a and the signal indicating the presence of the component in the component storage unit 100a, the cutting site CU of the carrier tape 100 is obtained. For example, as shown in FIG. 10B, when the pitch of the component storage portions 100a is Ph, the carrier tape 100 is moved to the conveyance pitch (Ph) based on the position where the component presence signal “S2” is output twice in succession. / 2) is controlled to move only. As a result, the cutting part CU preceding by the pitch (Ph / 2) from the position where the first component presence signal “S2” is output, that is, the center position of the component storage unit 100a in which the first component Pa is stored, It is positioned at the tape detection position Ld.

  In this state, the motor 70 of the tape cutting device 55 is driven, and the cutting portion CU of the carrier tape 100 is cut by the cutting cutter 68. Thereafter, the carrier tape 100 is transported by a predetermined amount D1 from the tape cutting position Lc, so that the two carrier tapes 100 are moved to the first positioning pins 113 and 114 whose feed holes 100c are provided at the splicing position Ls. Each is positioned at the engageable splicing position Ls, and the leading ends of the two carrier tapes 100 are abutted.

  On the other hand, the protective tape 31 to which the splicing tape 30 is attached is sent out by a feeding device (not shown), and one set of the splicing tape 30 is transported toward the splicing position Ls for the front surface and the back surface, and the first and second splicing tapes 30 are transported. Based on the signals of the detection sensors 48 and 49, the splicing position Ls is set. Thereby, 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 113 and 114 of the tape connecting portion 15 provided at the splicing position Ls (see FIG. 7).

  When the two carrier tapes 100 and the splicing tape 30 are respectively positioned at the splicing position Ls, the first and second lifting platforms 111 and 112 are raised, whereby the first positioning pins 113 and 114 are moved to the protective tape 31, The second positioning pin 115 is engaged with the positioning hole 31 b of the protective tape 31 while being engaged with the positioning hole 30 b 1 of the back surface splicing tape 30 b and the feeding holes 100 c of the two carrier tapes 100.

  Next, the second lifting platform 112 is turned 180 degrees in the direction of the arrow in FIG. 9A, the protective tape 31 engaged with the second positioning pins 115 is bent, and the surface splicing tape 30a has the adhesive surface at the upper position of the carrier tape 100. Inverted downward. That is, the protective tape 31 is bent so as to sandwich the carrier tape 100, and the back surface splicing tape 30 b is positioned on the back surface side of the carrier tape 100 and the front surface splicing tape 30 a is positioned on the front surface side of the carrier tape 100.

  Subsequently, the second lifting platform 112 is lowered, and as shown in FIG. 9B, the second positioning pins 115 are engaged with the feeding holes 100c of the carrier tape 100 and the positioning holes 30b1 of the back surface splicing tape 30b, Pressed against the first lifting platform 111. By this pressing, the back surface splicing tape 30b attached to the protective tape 31 is bonded so as to straddle the back surface of the carrier tape 100, and the front surface splicing tape 30a is attached to the surface of the carrier tape 100. The end portion of one carrier tape 100 and the start end portion of the other carrier tape 100 are connected to each other.

  Thereafter, the first and second lifting platforms 111, 112 are lowered and raised, and the first and second positioning pins 113, 114, 115 are positioned in the positioning hole 30b1 of the splicing tape 30b, the positioning hole 31b of the protective tape 31, and the two The carrier tape 100 is separated from each feed hole 100c. At this time, since the adhesiveness of the splicing tape 30 to the carrier tape 100 is high, the protective tape 31 is easily peeled off from the splicing tape 30. The carrier tapes 100 connected to each other are taken out from the splicing units 13 and 14 and the splicing device 10 by opening a lid (not shown).

  According to the above-described embodiment, the splicing device 10 includes the device main body 11, the tape connecting portion 15 that is provided in the device main body 11 and connects the two carrier tapes 100 transported to the splicing position Ls by the splicing tape 30.

And a pair of splicing units 13 and 14 including a tape transport device 51 that transports the carrier tape 100 along the tape guide 59 and a detection unit 53 for detecting a position at which the carrier tape 100 is cut.

  Accordingly, by preparing a plurality of splicing units 13 and 14 having tape guide portions 59 corresponding to the tape width of the carrier tape 100, it is possible to handle a plurality of types of carrier tapes 100 having different tape widths while sharing the apparatus main body 11. A possible splicing device 10 can be obtained. As a result, individual splicing devices 10 corresponding to different tape widths can be dispensed with, and splicing can be implemented economically.

  According to the above-described embodiment, since the splicing units 13 and 14 include the tape cutting device 55 that cuts the carrier tape 100, the tape cutting device 55 corresponding to the tape width is provided in each of the splicing units 13 and 14. The cutting accuracy of the cutting part CU of the carrier tape 100 can be increased.
