The left and right cutting means 48 perform a cutting operation in conjunction with the operation in which the lower mechanism unit 14 moves backward from the reference position described above. For this reason, from the state where the cutting point set in the component tape 2 is positioned in front of the cutting position TC (FIG. 7A), the lower mechanism portion 14 is moved rearward from the reference position to move the component tape traveling path 11. When moved rearward (arrow C1 shown in FIG. 7B), the cutting location set on the component tape 2 moves to the cutting position TC and is cut by the cutting means 48 (FIG. 7B). After the component tape 2 is cut by the cutting means 48, the lower mechanism portion 14 is returned to the reference position by the lower mechanism portion driving means 47 (FIG. 7 (c), arrow C2 shown in the figure).

  As shown in FIG. 8, the upper mechanism portion 15 has a lifting base 52 that can be lifted and lowered by a pair of shafts 51 guided by a shaft guide BS2 fixed to the base BS1 (see also FIG. 3). ). The elevating base 52 is moved up and down between a standby position shown in FIG. 3 and a lowermost moving position by a tool driving means 53 (for example, a motor) attached to a fixing member BS3 fixed to the base BS1. Is done.

Is located at the same height (or slightly above) as the lower surface of the pressing tool 58, and when the lower mechanism portion 14 is located at the reference position, the trailing edge of the movable lower receiving surface 42b is It substantially coincides with the rear edge of the pressing tool 58, and the alignment pin 45 is located immediately below the pressing tool 58. The lower surface of the pressing tool 58 is fixed to the fixed lower receiving surface 41a and the movable lower receiving surface 42b in plan view. Located across. The front edge of the bending tool 59 is positioned slightly behind the rear edge of the movable lower receiving surface 42b (approximately the thickness of the splicing tape 3).

  3 and 8, the rear mechanism 16 includes a horizontal flat plate bending tool stopper 61 fixed with respect to the base BS1, and two left and right bendings as second bending means extending forward. It comprises fork drive means 64 (for example, a motor) for moving a fork holding member 63 having a fork 62 in the front-rear direction behind the lower mechanism portion 14.

  In FIG. 9, the drive control of the two sprockets 12 by the sprocket drive means 21, the detection control of the presence or absence of the component P in the component storage portion 2 a at the component inspection position by the component sensor 22, and the feed hole inspection position by the feed hole sensor 23. Control for detecting presence / absence of the feed hole 2b of the component tape 2, feed control of the tape member TB (that is, the splicing tape 3) by the splicing tape feed drive unit 32, start position detection control of the splicing tape 3 by the head position detection sensor 36, The cutting operation of the splicing tape 3 by the cutter 37 is controlled by a control device 70 provided in the splicing device 1. Further, the forward and backward movement control of the lower mechanism portion 14 by the lower mechanism driving means 47, the raising and lowering control of the lifting base 52 (that is, the pressing tool 58 and the bending tool 59) by the tool driving means 53, and the bending by the fork driving means 64. The control device 70 also controls the movement of the fork 62 in the front-rear direction.

  In the present embodiment, as the component tape 2 that can be handled by the splicing device 1, the component storage portion 2a corresponds to the feed hole 2b (the position just beside the feed hole 2b when viewed in the width direction of the component tape 2). ) And a position corresponding to an intermediate position between adjacent feed holes 2b (referred to as “a position not corresponding to the feed hole 2b” for convenience) (FIG. 10). It is assumed that there are two types (part (a)) and a part housing part 2a only at a position not corresponding to the feed hole 2b (second type, FIG. 10 (b)).

  The control device 70 sets the feed amount for one pitch feed operation of the component tape 2 by the sprocket 12 to the type of component tape 2 (here, the first type of component tape 2) with the smallest interval between the component storage portions 2a. It is set to “N” corresponding to the interval between the component storage portions 2a (this is “N”). For this reason, as shown in FIGS. 10A and 10B, the interval between the feed holes 2b of the component tape 2 is “2N”, which is the length of two pitch feeding operations of the sprocket 12 regardless of the type of the component tape 2. is there. As shown in FIGS. 11 to 13, the interval between the feed hole inspection position and the component inspection position and the interval between the component inspection position and the cutting position TC are both set to “4N”.

  Next, the execution procedure of the feeding operation of the component tape 2 (the feeding method of the component tape 2) performed by the control device 70 will be described using the flowchart of FIG. Here, the feeding operation of the component tape 2 for one of the left-side traveling path 11L and the right-side traveling path 11R is shown, but the operation is the same for both the left and right sides and is performed independently.

  When the main switch 71 (FIG. 9) connected to the control device 70 is operated by the operator OP, the control device 70 starts monitoring the inspection information of the component sensor 22 and the feed hole sensor 23. Then, when the component tape 2 is inserted by the operator OP from the outer end side of the end side traveling path 11b and the feed hole 2b of the component tape 2 is detected by the feed hole sensor 23 (in the flowchart shown in FIG. 14). Step ST1) starts the pitch feeding operation of the component tape 2 at a predetermined time interval, and stores the detection result of the component sensor 22 and the detection result of the feed hole sensor 23 every time one pitch feeding is completed (step ST1). Step ST2). That is, in this step ST2, while the component tape 2 is pitch-fed, the presence or absence of the component P in the component storage portion 2a of the component tape 2 is detected by the component sensor 22, and the feed hole 2b of the component tape 2 is detected by the feed hole sensor 23. This is a process for detecting the presence or absence of the.

  The component storage portion 2a of the component tape 2 inserted into the end side traveling path 11b is an empty space in which the component P is not stored for a certain period from the top of the component tape 2 (about four feed holes 2b). The state is continuous. For this reason, the detection state of the component sensor 22 is that “light reception” continues for the first type component tape 2 immediately after the start of pitch feeding, and “light reception” and “non-light reception” are repeated for the second type component tape 2. It is. When the two component sensors 22 are continuously “non-light-receiving” (step ST3), the control device 70 reads the detection results for the last four times including the detection results at that time, Based on the content, the cutting location of the component tape 2 is set (step ST4).

  In step ST4, the control device 70 (1) without cutting the component P, (2) the component tape at a position passing through the center of the feed hole 2b so that the empty component storage portion 2a is reduced as much as possible. The cutting location is set on the basis of cutting 2. In order to satisfy this standard, the control device 70 refers to the past four detection results including the detection results at the time when the component sensor 22 continues to perform “non-light reception” two times in succession. If “non-light reception” is after “light reception” and “light reception” (“light reception” → “light reception” → “non-light reception” → “non-light reception”), the component tape 2 Is determined to be the first type of component tape 2 (FIG. 11 or FIG. 12), and the two “non-light reception” continued after “non-light reception” and “light reception” continued alternately. In the case (“non-light reception” → “light reception” → “non-light reception” → “non-light reception”), it is determined that the component tape 2 is the second type component tape 2 (FIG. 13). Further, when it is determined that the component tape 2 is of the first type, when the feed hole sensor 23 at the time of detection of “non-light reception” after two “non-light reception” is “light reception”, The first component P on the head portion side of the component tape 2 (the head component P1 in FIGS. 11 to 13) is in the component storage portion 2a that does not correspond to the feed hole 2b (FIG. 11 is assumed to be the first case). If the feed hole sensor 23 is “non-light-receiving” at the time of detection of “non-light-receiving” after the two consecutive “non-light-receiving”, the leading part P1 corresponds to the feeding hole 2b. It is determined that it is in the component storage section 2a (FIG. 12 is referred to as a second case).

  As a result of the above determination, the control device 70 determines that the component tape 2 corresponding to the first case of the first type is the component detection position at the time of the determination completion ( A position passing through the center of the feed hole 2b on the leading side of the component tape 2 by a length of “2N” from the component detection position where “non-light reception” is detected is set as a cutting position (FIG. 11). For the component tape 2 corresponding to the second case, a position passing through the feed hole 2b on the head portion side of the component tape 2 by the length “3N” from the component detection position at the time of completion of determination is set as a cutting position ( FIG. 12). For the component tape 2 corresponding to the second type, a position passing through the feed hole 2b on the head portion side of the component tape 2 by the length “N” from the component detection position at the time of completion of determination is set as a cutting position. (FIG. 13).

  As described above, the step ST4 is based on the detection information on the presence / absence of the component P in the component storage portion 2a by the component sensor 22 and the detection information on the presence / absence of the feed hole 2b by the feed hole sensor 23. It is a process of setting a cutting location.

  After setting the cutting location of the component tape 2 as described above, the control device 70 sends the set cutting location to the cutting position TC of the component tape 2 by the cutting means 48 (step ST5). Specifically, for the component tape 2 corresponding to the first case of the first type, the control device 70 performs two pitch feed operations of the sprocket 12 from the time when the above determination is completed, and lengthens the component tape 2. Advance by “2N” (FIG. 11), and for the component tape 2 corresponding to the second case of the first type, the pitch feed operation of the sprocket 12 is performed three times from the time when the determination is completed, and the length of the component tape 2 is increased. Advance by “3N” (FIG. 12). In addition, for the component tape 2 corresponding to the second type, one pitch feed operation of the sprocket 12 is performed from the time when the determination is completed, and the component tape 2 is advanced by the length “N”. That is, step ST5 is a step of driving the sprocket 12 so that the set cutting position is located at the cutting position TC of the component tape 2 by the cutting means 48.

  When the control device 70 sends the set cutting position of the component tape 2 to the cutting position TC, the control device 70 temporarily stops the feeding operation of the component tape 2 by the sprocket 12 (step ST6), and cuts the component tape 2 as described above. (Step ST7). Due to the cutting of the component tape 2, the feed hole 2b passing through the cut portion is divided in half and becomes a semicircular shape opened to the leading end side of the component tape 2 (FIGS. 7C and 15A).

  After cutting the component tape 2, the control device 70 operates the sprocket 12 to restart the feeding operation of the component tape 2 (step ST8), and the semicircular feeding formed at the leading end of the component tape 2 After the pitch feed operation of the sprocket 12 is performed a predetermined number of times necessary to reach the position where the inner peripheral portion of the hole 2b contacts the alignment pin 45 of the lower mechanism portion 14 (step ST9), the feed operation of the component tape 2 is performed. Is stopped (step ST10).

  By performing the feeding operation of the component tape 2 according to the above procedure, after the two component tapes 2 inserted from the left and right of the component tape traveling path 11 have traveled to the side toward the alignment pin 45 (FIG. 15A). The arrow A) shown in the figure shows a state in which the cylindrical alignment pin 45 is sandwiched by the divided semicircular feed holes 2b (FIG. 15B). As described above, in the present embodiment, the two component tapes 2 are cut at the positions passing through the centers of the feed holes 2b of the two component tapes 2 and the end tapes are formed by the semicircular feed holes 2b. The cylindrical alignment pin 45 provided on the traveling path 11 is abutted in a sandwiched state.

  As described above, in the present embodiment, the control device 70 as the control unit includes the detection information on the presence / absence of the component P in the component storage unit 2a by the component sensor 22 and the detection information on the presence / absence of the feed hole 2b by the feed hole sensor 23. The cutting position of each component tape 2 is set based on the above, and the sprocket 12 is driven so that the set cutting position is located at the cutting position TC of the component tape 2 by the cutting means 48. Further, regarding the setting of the above-mentioned cutting location, in detail, a switching pattern of the detection information of the presence or absence of the component P in the component storage unit 2a by the component sensor 22 (a pattern of switching between “light reception” and “non-light reception”) ) And the detection information of the presence / absence of the feed hole 2b by the feed hole sensor 23, the type of the component tape 2 is determined, and the cutting location of each component tape 2 is set according to the determined type of the component tape 2 It is supposed to be.

  After the two component tapes 2 are abutted, the control device 70 controls the operation of the splicing tape transport unit 13 and is cut into a predetermined length by a cutter 37 as shown in FIG. The resulting splicing tape 3 is positioned above the alignment pin 45. At this time, the front edge of the splicing tape 3 is positioned in front of the alignment pin 45, and the rear edge of the splicing tape 3 is positioned to protrude rearward from the rear edge of the component tape 2 (FIG. 17).

  When the splicing tape 3 is positioned above the alignment pin 45, the control device 70 operates the tool driving means 53 to lower the lifting base 52 from the standby position. Accordingly, the pressing tool 58 and the bending tool 59 are lowered integrally with the lifting base 52 (arrow D1 shown in FIG. 16B), and the pressing tool 58 is moved from above to a partial area on the front side of the splicing tape 3. After abutting and pressing the lower surface of the part against the two component tapes 2 whose leading end surfaces are abutted with each other (FIGS. 15C and 16B), the alignment pin 45 is moved up and down by the pressing tool 58 at this time. When the lower surface of the pressing tool 58 comes into contact with the fixed lower receiving surface 41a (and the movable lower receiving surface 42b located at the normal position) via the splicing tape 3, the pressing tool 58 is lowered. It becomes a regulated state. However, since the controller 70 continues to lower the lifting base 52, the spring 56b inserted through the front shaft 56 is compressed between the pressing tool 58 and the lifting base 52 (FIG. 18), and the restoring force of the spring 56b is reduced. It acts as a pressing force of the splicing tape 3 against the component tape 2 by the pressing tool 58.

  On the other hand, as described above, since the front edge of the bending tool 59 is located rearward of the rear edge of the movable lower receiving surface 42b, the lowering of the pressing tool 58 is restricted after the pressing tool 58 is restricted. A part of the splicing tape 3 that descends rearward and protrudes rearward from the rear edge of the component tape 2 (referred to as a folded portion 3S; see FIG. 15 (c)) on the vertical rear surface 42d (FIG. 17) of the elevating part 42. Bend down along (Fig. 18).

  After the bending tool 59 bends the splicing tape 3 downward, lowering is restricted when it comes into contact with the bending tool stopper 61 from above (FIG. 18). At the same time, the lower end portion of the pressing rod 55 contacts the rod contact surface 42a of the elevating unit 42 from above, but the controller 70 continues to lower the elevating base 52, so that the elevating base 52 is attached to the rear shaft 57. The elevating part 42 is pushed down against the urging force of the elevating part urging spring 44 by the pressing rod 55 while the inserted spring 57 b is compressed between the bending tool 59 and the elevating base 52. As a result, the movable lower receiving surface 42b of the elevating part 42 is lowered, and the component tape 2 is held between the fixed lower receiving surface 41a and the lower surface of the pressing tool 58, while the component tape 2 A space SP is formed between the movable receiving surface 42b of the elevating unit 42 (FIG. 19).

  When the control device 70 lowers the lifting base 52 to the above-described lowest movement position where the movable lower receiving surface 42b of the lifting portion 42 has a predetermined height H (FIG. 19), the tool driving means 53 lowers the lifting base 52. Then, the fork driving means 64 is operated to move the fork holding member 63 forward (arrow E shown in FIG. 20). As a result, the two folding forks 62 are inserted through an operation fork insertion groove (not shown) formed through the bending tool 59 in the front-rear direction from the rear to the front, and the space SP below the component tape 2 is inserted. Get inside. During this time, the folded portion 3S of the splicing tape 3 folded downward by the folding tool 59 is pushed up by the two folding forks 62 and folded back to the lower surface side of the component tape 2 (FIG. 20).

  When the splicing tape 3 is folded back to the lower surface side of the component tape 2, the control device 70 operates the tool driving means 53 to raise the lifting base 52. As a result, the elevating part 42 rises while receiving the two folding forks 62 in the two slits 42S by the urging force of the elevating part urging spring 44, and the splicing tape 3 folded back on the lower surface side of the component tape 2 is folded. The movable lower receiving surface 42b is pressed against the portion 3S from below and the portion is pressed against the lower surface of the component tape 2 (FIG. 21).

  Thus, in the present embodiment, the splicing device 1 includes a first pressing means (pressing tool 58) that presses the splicing tape 3 transported to the predetermined position by the splicing tape transport unit 13 against the two component tapes 2. First folding means (folding tool 59) that pushes down the folded portion 3S protruding to the side of the component tape 2 of the splicing tape 3 pressed against the two component tapes 2 by the first pressing means and folds downward. ), By the second folding means (folding fork 62) and the second folding means for folding the folded portion 3S bent downward by the first folding means to the lower surface side of the two component tapes 2. 2nd pressing means (elevating part 42) for pressing the folded portion 3S bent to the lower surface side of the component tape 2 against the lower surface side of the component tape 2 is provided. And it has a formation. The pressing tool 58 serving as the first pressing means and the elevating unit 42 serving as the second pressing means are driven by the same driving means called the tool driving means 53.

  When the controller 70 presses the folded portion 3S of the splicing tape 3 folded back on the lower surface side of the component tape 2 against the lower surface of the component tape 2, the control device 70 operates the tool driving means 53 to raise the lifting base 52 to the standby position. While the elevating base 52 is raised from the lowest movement position to the standby position, first, the bending tool 59 is separated from the tool stopper 61 and is moved up integrally with the elevating base 52, and then the pressing tool 58 is separated from the splicing tape 3. Then, it moves up integrally with the lifting base 52 (arrow D2 shown in FIG. 16C). As a result, the splicing tape 3 is affixed to the butted portion of the two component tapes 2, and the connection of the two component tapes 2 by the splicing tape 3 is completed (FIG. 15 (d)).

  When the control device 70 raises the elevating base 52 to the standby position, the lower mechanism drive means 47 moves the lower mechanism 14 forward from the reference position, and pushes the component tape 2 connected by the splicing tape 3 to the pressing rod 55. It pushes out to the position ahead (FIG. 22). As a result, the operator OP can take out the component tape 2 connected by the splicing tape 3 from the splicing device 1.

  As described above, in the splicing device 1 according to the present embodiment, the two component tapes 2 are advanced in the direction approaching each other on the component tape traveling path 11, and the end surfaces of the two component tapes 2 are abutted with each other. The splicing tape 3 is transported to a predetermined position above the abutting portion of the two component tapes 2, and the splicing tape 3 transported to the predetermined position is pressed against the two component tapes 2. The folded part 3S protruding to the side is bent downward and the two parts tape 2 are bent to the lower surface side, and then pressed to the lower surface side of the component tape 2. Splicing work is performed automatically. For this reason, the burden on the operator OP in the splicing work can be greatly reduced, and the variation in work accuracy can be reduced.

  Provided is a splicing device that can greatly reduce the burden on an operator in splicing work and can reduce variations in work accuracy.
