1. Embodiment Hereinafter, an embodiment in which the splicing device is embodied will be described with reference to the drawings. The splicing device splices the pair of carrier tapes by pasting the splicing tape on both sides with the ends of the pair of carrier tapes abutted. For example, one of the pair of carrier tapes is an old tape in use, and the other is a new tape for replenishment.

1-1. Configuration of Splicing Device 10 As shown in FIG. 1, the splicing device 10 includes a device main body 11, an upper cover 12, a carrier tape transport device 13, a cutting device 14, a supply tape transport device 15, and a tape sticking device 16. , A switch 17, a tape end detection sensor 18, a component detection sensor 19, and a control device 20. The device body 11 is formed in a rectangular parallelepiped shape as a whole. The apparatus main body 11 is formed with an insertion port 111 into which a carrier tape 90 (see FIG. 2) is inserted on both sides in the longitudinal direction (left and right direction in FIG. 1).

The two insertion ports 111 communicate with each other through a tape transport path 112 formed inside the apparatus main body 11. The tape transport path 112 is a groove extending in the left-right direction of the splicing device 10. The tape transport path 112 supports a pair of carrier tapes 90 to be spliced inserted from the respective insertion ports 111.

The upper cover 12 is a cover member that is opened and closed with respect to the apparatus main body 11. The upper cover 12 constitutes the upper surface of the tape transport path 112 in the closed state. The upper cover 12 is opened in the post-splicing extraction process to releasably release the spliced carrier tape 90.

The carrier tape transport device 13 transports a pair of carrier tapes 90 inserted from the two insertion ports 111 along the tape transport path 112, respectively. Here, as shown in FIG. 2, the carrier tape 90 is a tape member that accommodates a large number of components 93. The carrier tape 90 has a base tape 91 and a cover tape 92 (shown by a broken line in FIG. 2). A cavity 911 is formed in the central portion of the base tape 91 in the width direction (vertical direction in FIG. 2).

The cavity 911 is formed in a concave shape having a bottom. The cavities 911 are formed at regular intervals in the longitudinal direction (left and right direction in FIG. 2) of the base tape 91. Each cavity 911 houses one component 93. Further, in the base tape 91, a feed hole 912 is formed at an edge on one side in the width direction. The feed holes 912 are formed at constant intervals Nf in the longitudinal direction of the base tape 91. The feed holes 912 engage with the teeth of the sprockets 131 of the carrier tape transport device 13 and are used to transport the carrier tape 90.

The cover tape 92 is formed of a thin film-like polymer film. Both ends in the width direction of the cover tape 92 are adhered to the upper surface of the base tape 91. Thus, the cover tape 92 closes the opening of the cavity 911. This prevents the component 93 stored in the cavity 911 of the base tape 91 from falling off.

Here, in the present specification, a straight line parallel to the longitudinal direction of the carrier tape 90 and passing through the plurality of cavities 911 (hereinafter referred to as “part line Lp”) and an end portion of the carrier tape 90 (thick line in FIG. 2) The point of intersection with the edge line Le) shown is defined as "tape end". The tape end Dt of the carrier tape 90 is located on the part line Lp, even if the end of the carrier tape 90 is inclined with respect to the transport direction, as shown by the thick broken line in FIG. In the present embodiment, the part line Lp passes through the centers of the plurality of cavities 911 in the width direction of the carrier tape 90 (vertical direction in FIG. 2).

The carrier tape transport device 13 rotates the sprockets 131 to transport the pair of carrier tapes 90 along the tape transport path 112. Thereby, the carrier tape transport device 13 positions the cutting position of the pair of carrier tapes 90 with respect to the first cutting position Pc1 or the second cutting position Pc2. Further, the carrier tape transport device 13 transports the pair of cut carrier tapes 90 in a direction to approach each other, and positions respective end portions of the pair of carrier tapes 90 with respect to the splicing position Ps. The above-mentioned "splice position Ps" is a position provided at the center in the left-right direction of the splicing device 10, and is a position at which a pair of carrier tapes 90 are connected by splicing.

The cutting device 14 performs a cutting process of cutting a pair of carrier tapes 90 inserted from the respective insertion ports 111 at a predetermined cutting point set by the cutting point setting unit 21 of the control device 20 described later. In the present embodiment, the cutting device 14 includes a first cutter 141 disposed corresponding to the first cutting position Pc1 on the tape conveyance path 112 and a second cutter 142 disposed corresponding to the second cutting position Pc2. Have.

The first cutter 141 and the second cutter 142 cut a pair of carrier tapes 90 conveyed by the tape conveyance path 112 by the carrier tape conveyance device 13 in the cutting process. In the present embodiment, the cutting device 14 cuts the pair of carrier tapes 90 in a series of operations by the first cutter 141 and the second cutter 142. The cutting device 14 discards an unnecessary portion (cut-off portion) of the carrier tape 90 generated by the cutting process from a duct (not shown).

The supply tape transport device 15 transports the supply tape 80 and exposes the splicing tape 83 from the supply tape 80 so as to be stuck in the splicing process. Here, as shown in FIG. 3, the supply tape 80 is a three-layered tape member in which a plurality of splicing tapes 83 are sandwiched between the base tape 81 and the cover tape 82 (indicated by a broken line in FIG. 3). . On the base tape 81, two of a front surface splicing tape 831 and a rear surface splicing tape 832 (hereinafter simply referred to as "pair of splicing tapes 83") are attached at predetermined intervals.

The base tape 81 is formed with a plurality of feed holes 811 at regular intervals along the longitudinal direction of the base tape 81 at both end portions in the width direction. The feed holes 811 engage with the teeth of a sprocket (not shown) of the supply tape transfer device 15 and are used to transfer the supply tape 80. The base tape 81 is formed with positioning holes 812 along the width direction of the base tape 81. The positioning holes 812 are used to position the supply tape 80 with respect to the pair of carrier tapes 90 to be spliced.

The cover tape 82 is a film member attached so as to cover a plurality of sets of splicing tape 83 attached to the base tape 81. Of the pair of splicing tapes 83, the surface splicing tape 831 is attached to the surfaces of the pair of carrier tapes 90 so as to straddle the pair of carrier tapes 90. The back surface splicing tape 832 of the pair of splicing tapes 83 is attached to the back surfaces of the pair of carrier tapes 90 so as to straddle the pair of carrier tapes 90.

The supply tape conveyance device 15 conveys the supply tape 80 and peels the cover tape 82 from the base tape 81. Thus, the supply tape transport device 15 exposes the pair of splicing tapes 83 attached to the base tape 81. The pair of splicing tapes 83 is in the state of straddling both ends of the pair of carrier tapes 90 positioned with respect to the splicing position Ps.

The tape sticking device 16 sticks the pair of splicing tapes 83 on the front and back surfaces of the pair of carrier tapes 90. Specifically, the tape sticking apparatus 16 folds back part of the supply tape 80 in which the pair of splicing tapes is exposed. Then, the tape sticking apparatus 16 presses the pair of splicing tapes 83 against the front and back surfaces of the pair of carrier tapes 90 positioned at the splicing position Ps.

As a result, the pair of splicing tapes 83 is bonded to the pair of carrier tapes 90 when a predetermined pressing force is applied. Thereafter, the pair of splicing tapes 83 is peeled from the base tape 81 and taken out from the splicing device 10 together with the spliced carrier tape 90 in the takeout process after splicing.

The switch 17 accepts a switching operation by the operator in order to switch the operation mode of the splicing process. In the present embodiment, the operation mode of the splicing process includes a normal mode and two types of regulation modes. The switch 17 is set to any one of four types of states: a state in which the normal mode is selected by switching operation, two states in which two types of regulation modes are selected, and a state in which these are automatically selected. Ru. Details of the switching of the operation mode will be described later.

The tape end detection sensor 18 detects an end of the carrier tape 90 at a predetermined position on the tape conveyance path 112. The tape end detection sensor 18 is, for example, a photoelectric sensor including a light emitting unit that emits light from above the tape conveyance path 112 and a light receiving unit that receives light at the lower side of the tape conveyance path 112. In the present embodiment, the tape end detection sensor 18 is provided so as to detect the central portion of the plurality of cavities 911 in the width direction of the carrier tape 90 supported by the tape transport path 112. Thus, the tape end detection sensor 18 detects the tape end Dt at the end of the carrier tape 90.

The tape end detection sensor 18 outputs a signal according to the detection result to the control device 20 described later. In addition, the tape end detection sensor 18 is disposed at a position away from the rotation center of the sprocket of the carrier tape transport device 13 in the tape transport path 112 by a predetermined distance in the transport direction. As a result, the control device 20 described later detects the tape end Dt, and the feed hole 912 of the carrier tape 90 on the basis of the rotation angle of the sprocket of the carrier tape transport device 13 when the tape end Dt is detected. Recognize the positional relationship between and the tape end Dt.

The part detection sensor 19 detects the part 93 stored in the cavity 911 of the carrier tape 90. In other words, the component detection sensor 19 is a detection sensor that detects an empty cavity in which the component 93 is not stored among the plurality of cavities 911 of the carrier tape 90. The component detection sensor 19 is, for example, a photoelectric sensor having a light emitting unit and a light receiving unit, like the tape end detection sensor 18. The component detection sensor 19 outputs a signal according to the detection result to the control device 20. The control device 20 recognizes the number of empty cavities in the carrier tape 90 and the distance between two adjacent cavities 911 based on the detection result by the component detection sensor 19.

The control device 20 mainly includes a CPU, various memories, and a control circuit. The control device 20 executes the splicing process based on a preset program or parameter. In the splicing process, the control device 20 appropriately sets the transport amount and the cut location of the carrier tape 90 based on the information output from various sensors, and controls the operation of the carrier tape transport device 13 and the cutting device 14 etc. . Further, in the present embodiment, as shown in FIG. 1, the control device 20 includes a cutting point setting unit 21, a mode switching unit 22, and a position adjustment unit 23.

Here, the splicing process in the normal mode includes a cutting process for cutting the pair of carrier tapes 90 and a tape sticking process for sticking the splicing tape 83 to the carrier tape 90 after cutting. In the cutting process, the cutting point setting unit 21 selects a pair of carrier tapes 90 according to the type (for example, the interval of the cavities 911) and the state (for example, the number of empty cavities) of the carrier tape 90 inserted in the splicing device 10. Set the cutting point in.

In the normal mode splicing process as described above, the pair of carrier tapes 90 are cut along the length appropriately from the end and spliced so that there is no empty cavity at the joint. Therefore, depending on a state in which the number of empty cavities in the carrier tape 90 is smaller than a predetermined number or the like, the carrier tape 90 is cut off an appropriate length including the cavity 911 for housing the component 93. Parts 93 stored in the cut-off portion are to be discarded.

By the way, for example, in the case where there is no margin in the number of specific component types, it is a priority that no discarding of components occurs in the splicing process. Therefore, in the cutting process, the cutting point setting unit 21 in the present embodiment performs the first end of the first carrier tape 901 (see FIGS. 1 and 2) which is one of the pair of carrier tapes 90 (hereinafter referred to as “first The first cutting point T1 is set so that the tape end Dt1 ′ ′) is maintained without being cut off.

Specifically, the cut position setting unit 21 can adopt the following mode. In the first aspect, the cutting position setting unit 21 is configured to position the first tape end Dt1 at the arrangement position of the first cutter 141 in the tape conveyance path 112 (corresponding to the first cutting position Pc1) in the cutting process. One tape end Dt1 is set to the first cutting point T1. In the second embodiment, in the cutting process, the cutting position setting unit 21 inserts the first carrier tape 901 at the first tape end Dt1 relative to the arrangement position (the first cutting position Pc1) of the first cutter 141 in the tape conveyance path 112. The first cutting point T1 is set so as to be positioned on the side of the insertion port 111 to be cut.

In any of the first and second embodiments described above, the first tape end Dt1 of the first carrier tape 901 is not cut off by the cut of the first cutter 141. However, in the first embodiment, when the end portion of the first carrier tape 901 is inclined with respect to the longitudinal direction, the surplus portion protruding to the front side in the transport direction than the first tape end Dt1 (hatched line in FIG. 2 Part) is cut off. Thus, when the splicing tape 83 is attached, the surplus portion can be prevented from interfering with the second carrier tape 902 which is the other of the pair of carrier tapes 90.

Hereinafter, the operation mode of splicing processing for setting the first cut portion T1 by the cut portion setting portion 21 so as to maintain the first tape end Dt1 without being cut off in the cutting processing as described above is referred to as “regulatory mode”. . Here, in the normal mode splicing process described above, the first cutting point T1 and the second cutting point T2 are selected by the cutting point setting unit 21 so that both the first carrier tape 901 and the second carrier tape 902 are cut in the cutting process. The cutting point T2 is set.

Specifically, in the normal mode splicing process, for example, as shown in the first and second rows of FIG. The cutting point T1 is set. FIG. 4 shows two types of first carrier tapes 901, a first carrier tape 901 whose type can not be determined, and a first cut portion T1 corresponding thereto. In addition, since the second carrier tape 902 is symmetrical to the first carrier tape 901, in FIG.

On the other hand, in the splicing process in the restriction mode, the first tape end Dt1 of the first carrier tape 901 always remains even after the cutting process, so the first feed hole from the first tape end Dt1 in the longitudinal direction The length up to 912 is undefined. Therefore, in the cutting process of the splicing process in the restriction mode, the cutting point setting unit 21 of the present embodiment performs the second process based on the positional relationship between the plurality of feed holes 912 of the first carrier tape 901 and the first tape end Dt1. A second cutting point T2 of the carrier tape 902 is set. Specifically, the cut position setting unit 21 first selects the first position according to the operation state of the carrier tape transport device 13 (for example, the angle of the sprocket 131) when the first tape end Dt1 is detected by the tape end detection sensor 18. The length N1 from one tape end Dt1 to the first feed hole 912 is determined.

Next, the cutting point setting unit 21 sets the length N2 (see the third row in FIG. 6) from the tape end Dt2-2 of the second carrier tape 902 after the execution of the cutting process to the first feed hole to the next feed hole. The second cutting point T2 in the second carrier tape 902 is set so as to be equal to or less than the value (Nf−N1) obtained by subtracting the length N1 from the interval Nf of the matching feed holes 912 (N2 ≦ Nf−N1). According to such a configuration, execution of the cutting process can cut off a portion of the second carrier tape 902 that is unnecessary for splicing. Therefore, after being spliced, the state of the joint between the first carrier tape 901 and the second carrier tape 902 can be improved, and the spacing Nf of the perforations 912 at the joint can be maintained properly.

In the regulation mode of the splicing process, in addition to cutting the second carrier tape 902 as described above, the second carrier tape 902 is also the same as the first carrier tape 901, the tape end of the second carrier tape 902 , “The second tape end Dt2” may not be cut off. That is, the cutting point setting unit 21 sets the second cutting point T2 so that the second tape end Dt2 of the second carrier tape 902 is maintained without being cut.

At this time, the cutting position setting unit 21 is configured such that the second tape end Dt2 is positioned at the arrangement position of the second cutter 142 in the tape conveyance path 112 (corresponding to the second cutting position Pc2) in the cutting process. Dt2 may be set to the second cutting point T2. Further, the cutting position setting unit 21 is positioned so that the second tape end Dt2 is positioned on the insertion port 111 side where the second carrier tape 902 is inserted relative to the arrangement position of the second cutter 142 in the tape conveyance path 112 in the cutting process. The second cutting point T2 may be set to

The mode switching unit 22 switches between the normal mode and the restriction mode as an operation mode of the splicing process. In the present embodiment, the mode switching unit 22 switches between the normal mode and the restriction mode in accordance with the state of the switch 17 (the normal mode, two types of restriction modes, and the automatic selection mode). The first type of restriction mode is a type in which the second cutting point T2 of the second carrier tape 902 is set in accordance with the positional relationship between the feed hole 912 of the first carrier tape 901 and the first tape end Dt1. The second type of restriction mode is a type in which the second cutting position T2 is set so that the second tape end Dt2 of the second carrier tape 902 is maintained without being cut off during the cutting process.

In the above-mentioned "automatic selection mode", the operation mode of the splicing process is automatically selected according to the type and the state of the first carrier tape 901 and the second carrier tape 902 into which the splicing device 10 is inserted. In the present embodiment, the mode switching unit 22 switches between the normal mode and the restriction mode according to the number of empty cavities in the first carrier tape 901 detected by the component detection sensor 19.

Specifically, the mode switching unit 22 performs splicing, for example, when the number of empty cavities among the plurality of cavities 911 located from the end side of the first carrier tape 901 is equal to or less than a prescribed number (for example, one). Switch the operation mode of the process to the restriction mode. In addition, a worker etc. can set the above-mentioned prescribed number arbitrarily. Further, the type of regulation mode selected in the automatic selection mode may be fixed to any one of two types, or may be further selectable by the switch 17.

The position adjustment unit 23 adjusts the positioning of the first carrier tape 901 and the second carrier tape 902 with respect to the splicing position Ps based on the positional relationship between the plurality of feed holes 912 of the first carrier tape 901 and the first tape end Dt1. Do. Specifically, in the tape sticking process performed after the cutting process, the spacing Nf of the feed holes 912 at the joint between the first carrier tape 901 and the second carrier tape 902 is properly maintained regardless of the operation mode of the splicing process As such, adjust their positioning.

1-2. Splicing by Splicing Device 10 Splicing by the splicing device 10 will be described with reference to FIGS. 1, 2 and 4 to 6. Hereinafter, the carrier tape 90 inserted from the insertion port 111 on the left side of FIG. 1 is also referred to as a first carrier tape 901, and the carrier tape 90 inserted from the insertion port 111 on the right side of FIG. The splicing process is a process of splicing the front end of the first carrier tape 901 to the rear end of the second carrier tape 902. The switch 17 is selected in any state by the switching operation of the operator.

As shown in FIG. 5, the control device 20 first executes recognition processing of the pair of carrier tapes 90 (step 10 (hereinafter, "step" is described as "S")). Specifically, when detecting that the first carrier tape 901 has been inserted from the insertion port 111, the control device 20 causes the carrier tape transport device 13 to transport the first carrier tape 901 along the tape transport path 112. Then, the control device 20 recognizes the type and the state of the first carrier tape 901 based on the signals according to the detection results of the tape end detection sensor 18 and the component detection sensor 19.

By the recognition process for the first carrier tape 901, the length N1 from the first tape end Dt1 to the first feed hole 912, the number of empty cavities, and the spacing Nc of adjacent cavities 911 are recognized. In the configuration in which a photoelectric sensor is adopted as the component detection sensor 19 as in the present embodiment, the control device 20 can recognize the interval Nc of the cavities 911 when the number of empty cavities is two or more. When the number of empty cavities is 1 or less, the controller 20 assumes that the distance Nc between the cavities 911 is unknown.

The same recognition processing as that for the first carrier tape 901 is also performed for the second carrier tape 902. At this time, when the interval Nc of the cavities 911 of the first carrier tape 901 and the second carrier tape 902 is different, the control device 20 may notify the operator of an error as the type is different.

Next, the control device 20 executes a cutting point setting process (S20). When the switch 17 is in the state of the automatic selection mode (S21: Yes), the mode switching unit 22 sets the number of empty cavities among the plurality of cavities 911 located from the end side of the first carrier tape 901. It is determined whether the specified number has been reached (S22). The mode switching unit 22 sets the operation mode of the splicing process to the normal mode when the number of empty cavities is equal to or more than the specified number (S22: Yes). On the other hand, when the number of empty cavities is less than the specified number (S22: No), the mode switching unit 22 sets the operation mode of the splicing process to the restriction mode.

When the switch 17 is in the normal mode (S23: Yes), the mode switching unit 22 sets the operation mode of the splicing process to the normal mode. On the other hand, when the switch 17 is in any of the two restriction modes (S21: No, S23: No), the mode switching unit 22 sets the operation mode of the splicing process to the restriction mode. .

When the splicing process is set to the normal mode, the cut location setting unit 21 first sets the first cut location T1 of the first carrier tape 901 (S24). In detail, as shown in each row of FIG. 4, the cutting point setting unit 21 sets a first cutting point T1 at the center of adjacent cavities 911, which is a place where all the empty cavities are cut off. When the number of empty cavities is less than the specified number, the cutting position setting unit 21 sets the first cutting position T1 at a position to be cut away from the first tape end Dt1 by the specified length or more.

In addition, the number of empty cavities may be one or less, and the interval Nc between adjacent cavities 911 may not be known. In this case, as shown in the third row of FIG. 4, the cut position setting unit 21 has a type (Nc = Nf) where the spacing Nc of the cavities 911 is equal to the spacing Nf of the feed holes 912 and a half type (Nc = Nc). In consideration of Nf / 2), a position shifted by only 1⁄4 of the gap Nc from the cavity 911 to the cavity 911 is set as the first cutting point T1 so that the cavity 911 is not cut in any cases.

Next, the cutting point setting unit 21 sets a second cutting point T2 of the second carrier tape 902 (S25). The method of setting the second cutting point T2 in the normal mode is substantially the same as the setting (S24) of the first cutting point T1, and thus the detailed description is omitted. As a result, in the second carrier tape 902, the second cutting point T2 is set so that all the empty cavities are cut off and the centers of the adjacent cavities 911 are cut.

When the splicing process is set to the restriction mode, the cutting point setting unit 21 first sets the first tape end Dt1 to the first cutting point T1 (S31). For example, as shown in the first row of FIG. 6, the cutting point setting unit 21 sets the intersection point of the part line Lp of the first carrier tape 901 and the edge line Le as the first tape end Dt1, and this first tape end Dt1 is The first cutting point T1. This prevents the first tape end Dt1 from being cut off as shown in the second row of FIG. 6 in the later cutting process (S50). If the first carrier tape 901 has a surplus portion, the surplus portion is cut off in the cutting process (S50).

Next, the cut location setting unit 21 determines whether cutting of the second carrier tape 902 is permitted (S32). When the first type allowing cutting of the second carrier tape 902 out of the two types of restriction modes is selected according to the state of the switch 17 (S32: Yes), the cutting position setting unit 21 selects the second carrier tape 902. The second cutting point T2 of the second is set (S33). In the present embodiment, when the restriction mode is set in the automatic selection mode (S22: No), processing is performed assuming that the first type of restriction mode is selected.

In the setting of the second cutting point T2 (S33), the cutting point setting unit 21 first determines the difference between the distance Nf between the adjacent feeding holes 912 and the length N1 from the first tape end Dt1 to the first feeding hole 912 ( Calculate Nf-N1). Then, as shown in the third row of FIG. 6, the cutting location setting unit 21 uses the second tape from the feed hole 912 of the predetermined number (the third in FIG. 6) from the rear end of the second carrier tape 902. A point separated by the above difference (Nf-N1) on the end Dt2 side is set as a second cutting point T2.

At this time, the rear end of the second carrier tape 902 is cut off slightly longer than the above difference (Nf-N1) in order to reliably prevent overlapping of the first carrier tape 901 and the second carrier tape 902 after splicing. The second cutting point T2 may be set to The cutting point setting unit 21 performs the second tape end Dt2 of the second carrier tape 902 as the second tape end Dt2 of the second carrier tape 902 when it is the second type that does not allow the cutting of the second carrier tape 902 among the two types of regulation modes The second cutting point T2 is set (S41).

For example, as shown in the fourth row of FIG. 6, the cutting point setting unit 21 sets the intersection point of the part line Lp of the second carrier tape 902 and the edge line Le as a second tape end Dt2, and this second tape end Dt2 is Let it be the second cut point T2. This prevents the second tape end Dt2 from being cut off as shown in the fifth row of FIG. 6 in the later cutting process (S50). When the second carrier tape 902 has a surplus portion, the surplus portion is cut off in the cutting process (S50).

Subsequently, when the first carrier tape 901 and the second carrier tape 902 in which the first cutting point T1 and the second cutting point T2 are set as described above are positioned at the splicing position Ps, the position adjustment unit 23 It is determined whether the distance Ce in the transport direction between the first tape end Dt1 and the second tape end Dt2 exceeds a specified value Vc (S42). Here, the first carrier tape 901 and the second carrier tape 902 are positioned such that the distance Nf of the feed holes 912 at the joint between the first carrier tape 901 and the second carrier tape 902 is maintained.

However, due to the setting of the first cutting point T1 and the second cutting point T2 as described above, in the cutting process (S50), the first tape end Dt1 and the second tape end Dt2 are not cut off together. Therefore, the first carrier tape 901 and the second carrier tape 902 may overlap to some extent or be separated to some extent by being positioned. If the first carrier tape 901 and the second carrier tape 902 overlap or separate to a certain extent, there is a risk of causing splicing defects or causing operation defects when using the spliced carrier tape 90. is there.

Therefore, in the above determination (S42), the position adjustment unit 23 determines whether the first carrier tape 901 and the second carrier tape 902 are separated beyond the specified value Vc or overlap with each other. The control device 20 is normal when the distance Ce in the transport direction of the first tape end Dt1 and the second tape end Dt2 does not exceed the specified value Vc as shown in the fifth row of FIG. 6 (S42: No) Then, the disconnection point setting process (S20) is ended. On the other hand, when the distance Ce in the transport direction of the first tape end Dt1 and the second tape end Dt2 exceeds the specified value Vc (S42: Yes), the position adjustment unit 23 executes an error process (S43).

The above error processing includes restricting the application of the pair of splicing tapes 83 by the tape application device 16 later. As a result, the tape sticking apparatus 16 is restricted from sticking the pair of splicing tapes 83. In addition, the operator may be notified of an error to prompt the operator to decide whether to interrupt the tape sticking process or to allow continuation. As a result, the operator can cope with an error such as changing the selected operation mode or preparing the carrier tape 90 which has been manually cut.

Thereafter, the cutting process by the cutting device 14 is performed (S50). Specifically, the first carrier tape 901 is conveyed such that the first cutting position T1 set in the cutting position setting process (S20) is positioned at the first cutting position Pc1 on the tape conveyance path 112. Similarly, the second carrier tape 902 is conveyed such that the second cutting point T2 is located at the second cutting position Pc2 on the tape conveyance path 112. Thereafter, the cutting device 14 is driven such that the first cutter 141 passes the first cutting point T1 and the second cutter 142 passes the second cutting point T2.

By the above-described cutting process (S50), the first carrier tape 901 and the first carrier tape 901 and the second cutting point T2 are included in the edge line Le regardless of the operation mode in which the splicing process is performed. The second carrier tape 902 is cut. Thereafter, a tape sticking process is performed by the tape sticking apparatus 16 (S60). Specifically, the position adjustment unit 23 first performs the first carrier tape 901 and the second carrier tape 902 with respect to the splicing position Ps based on the positional relationship between the feed hole 912 of the first carrier tape 901 and the first tape end Dt1. Adjust the positioning of

The carrier tape transport device 13 transports the first carrier tape 901 and the second carrier tape 902 so as to approach the position adjusted by the position adjustment unit 23, and positions the first carrier tape 901 and the second carrier tape 902 with respect to the splicing position Ps. Then, the tape application device 16 is driven to attach the pair of splicing tapes 83 to the front and back surfaces of the first carrier tape 901 and the second carrier tape 902.

Thereby, the pair of splicing tapes 83 is pressed against the first carrier tape 901 and the second carrier tape 902. The first carrier tape 901 and the second carrier tape 902 are adhered to the pair of carrier tapes 90 by applying a predetermined pressing force. Thereafter, the upper cover 12 is opened, and the removal process is performed (S70). Thus, the pair of splicing tapes 83 is peeled off from the base tape 81 and can be taken out of the splicing device 10 together with the spliced first carrier tape 901 and the second carrier tape 902.

Effects of the Configuration of the Embodiment The splicing device 10 described above transports the first carrier tape 901 and the second carrier tape 902 each having a plurality of cavities 911 for housing the components 93 in a direction in which the first carrier tape 901 and the second carrier tape 902 approach. At the splicing position Ps by the cutting device 14 that performs the cutting process (S50) for cutting the first cutting point T1 of the first carrier tape 901 and the second cutting point T2 of the second carrier tape 902, respectively A tape sticking device 16 for sticking the splicing tape 83 to the first carrier tape 901 and the second carrier tape 902 positioned with respect to each other, and a straight line Lp parallel to the longitudinal direction of the first carrier tape 901 and passing through a plurality of cavities 911 And the first carrier te A cutting point setting unit that sets a first cutting point T1 so that the first tape end Dt1 is maintained without being cut off in the cutting process (S50) with the point of intersection with the end Le of the tape 901 as the first tape end Dt1. And 21.

According to such a configuration, the first carrier tape 901 which is one of the pair of carrier tapes 90 to be subjected to the splicing process is not cut off the first tape end Dt1 in the cutting process (S50) of the splicing process in the regulation mode. Maintained. Thereby, when the component 93 is stored in the first cavity 911 from the first tape end Dt1 of the first carrier tape 901, generation of discarding of the component 93 accompanying the execution of the cutting process (S50) is prevented. Can.
