Description

Splicing unit

The present invention relates to a splicing unit that replenishes electronic components using a splicing device that splices carrier tapes.

For example, some electronic component mounting machines include a carrier tape containing electronic components, and mount electronic components supplied from the carrier tape on a substrate. The electronic component mounting machine needs to be replenished with a new carrier tape before the carrier tape has run out of electronic components and the production line is stopped. Patent Document 1 describes a supply device that continuously supplies a carrier tape to an electronic component mounting machine. The supply device includes a plurality of cassette-type tape holders that accommodate supply reels, and automatically switches the supply reels by switching the positions of the plurality of cassette-type tape holders. Further, the supply device includes a splicing device that performs splicing of the carrier tape of the supply reel and the carrier tape included in the electronic component mounting machine. The splicing device performs splicing between the end of the carrier tape to be supplied that is likely to run out of parts and the start of the carrier tape for supply.

Japanese Patent Laid-Open No. 2015-76466

By the way, the above-described supply device automatically switches the supply reel and sets it in the splicing device. On the other hand, as a method of splicing, there is also a method in which an operator carries the supply reel by hand and sets it in the splicing device. In this case, for example, the operator unwinds a part of the carrier tape from the supply reel, and inserts the starting end of the unwound carrier tape into the splicing device to perform splicing. At this time, the carrier tape may be unnecessarily unwound from the supply reel. In particular, when the supply reel is unused and the carrier tape is wound up to the position of the outer peripheral edge of the reel, if the tape that stops the tip of the carrier tape is removed, the carrier tape needs to spread outside the reel. It will be solved. Thereby, there exists a possibility of causing the fall of work efficiency.

The present invention has been made in view of the above-described problems, and an object thereof is to provide a splicing unit that can improve the efficiency of work using a splicing device by an operator.

A splicing unit disclosed in this specification includes a splicing device that splics a carrier tape wound around a supply reel, a carrier tape to be supplied, a support unit that rotatably supports the supply reel, and a support unit The carrier tape that is unwound from the supported supply reel includes a restricting portion that restricts movement of the supply reel toward the outside in the radial direction.

According to this, the supply reel is rotatably supported by the support portion. For this reason, before the splicing operation, the carrier tape unwound from the supply reel can be easily pulled out while the supply reel is rotated and set in the splicing device. At this time, since the carrier tape that has been unwound from the supply reel is restricted by the restricting portion from moving in the radial direction of the supply reel, it can be prevented from being unnecessarily unwound. As a result, for example, after the splicing is finished, the operator does not need to rewind the carrier tape that has been unnecessarily unwound onto the supply reel, and the work efficiency can be improved.

(1. Configuration of splicing unit 10)
FIG. 1 shows an overall perspective view of the splicing unit 10. The splicing unit 10 includes a first carrier tape Tc1 of the supply reel 25 of the reel bucket 22 and a second carrier tape Tc2 (see FIG. 2) to be supplied to a reel loaded in a tape feeder of an electronic component mounting machine (not shown). Is a device for splicing by the splicing device 21.

As shown in FIG. 1, the splicing unit 10 includes a carriage unit 11 and a main body control unit 12. The cart unit 11 is configured by attaching a base table 14 on four casters 13 (only three are shown in FIG. 1). A power supply device 15 and a dust box 17 are disposed on the base table 14.

The power supply device 15 includes a battery, and supplies power to the splicing device 21 and the display device 24 when the power switch 12a of the main body control unit 12 is turned on. The dust box 17 is for discarding the cut ends (waste tape) of the first and second carrier tapes Tc1 and Tc2 that are generated during the splicing operation.

The main body control unit 12 is attached to an upper portion of the column portion 18 fixed on the base table 14. The main body control unit 12 includes a splicing device 21, a reel bucket 22, a barcode reader 23, and a display device 24.

The splicing device 21 attaches the end of the second carrier tape Tc2 (see FIG. 2) to be supplied wound around the reel loaded in the tape feeder (not shown) to the supply reel 25 accommodated in the reel bucket 22. This is a device for automatically splicing to the starting end of the wound first carrier tape Tc1. The splicing device 21 includes a main body 21a and an upper cover 21b attached to the main body 21a so as to be openable and closable. When the upper cover 21b is closed, the splicing device 21 has a substantially rectangular parallelepiped shape that is long in one direction. The splicing device 21 is provided with

insertion ports

31a and 31b (only the insertion port 31a on the front side is shown in FIG. 1) communicating with the inside and the outside of the splicing device 21 on each of the side surfaces opposed in the longitudinal direction. The

insertion ports

31a and 31b are provided at a boundary portion between the main body portion 21a and the upper cover 21b, and are formed by cutting out a part of the main body portion 21a and the upper cover 21b.

(1-1. Configuration of carrier tape)
FIG. 2 is a plan view showing a state in which the first carrier tape Tc1 for supply and the second carrier tape Tc2 to be supplied are spliced. The second carrier tape Tc2 is, for example, a carrier tape that runs out of reel components loaded in the tape feeder. The first and second carrier tapes Tc1, Tc2 have the same structure. For this reason, in the following description, 1st carrier tape Tc1 is mainly demonstrated and description about 2nd carrier tape Tc2 is abbreviate | omitted suitably.

The first carrier tape Tc1 includes a base tape Tb, an electronic component e, and a top tape Tt. The base tape Tb is long and narrow with a predetermined width. In the base tape Tb, feed holes Hc and component storage cavities Ct are arranged at the same interval Pc along the longitudinal direction. Each feed hole Hc is formed through the base tape Tb and has a circular shape in plan view of the base tape Tb. Each cavity Ct accommodates an electronic component e to be mounted on the substrate. The top tape Tt is detachably bonded to the upper surface of the base tape Tb.

Returning to FIG. 1, the splicing device 21 has the second carrier tape Tc2 (see FIG. 2) inserted into one of the two

insertion openings

31a and 31b, and the other insertion opening 31b ( The first carrier tape Tc1 for replenishment (see FIG. 2) is inserted into (see FIG. 3). When the first and second carrier tapes Tc1 and Tc2 are inserted into the

insertion ports

31a and 31b, the first and second carrier tapes Tc1 and Tc2 are arranged in the tape transport path 32 provided in the upper part of the main body 21a of the splicing device 21.

The upper cover 21b is provided with a mark 33 indicating that the second carrier tape Tc2 to be replenished should be inserted in accordance with the position of the insertion port 31a (for example, “Old Tape”). Further, the upper cover 21b is provided with a mark 34 indicating that the first carrier tape Tc1 for replenishment should be inserted in accordance with the position of the insertion port 31b (for example, “New Tape”). Each of the

marks

33 and 34 shows the direction of the feed hole Hc and the cavity Ct (see FIG. 2) when the first and second carrier tapes Tc1 and Tc2 are inserted into the

insertion ports

31a and 31b. Accordingly, the operator can easily determine which

insertion port

31a, 31b should be inserted in which direction the first and second carrier tapes Tc1, Tc2 by checking the

marks

33, 34. be able to.

The splicing device 21 holds the upper cover 21b in a closed state at the time of splicing, and when each of the first and second carrier tapes Tc1 and Tc2 is sent from the

insertion ports

31a and 31b to the tape transport path 32 by the operator, Unnecessary portions of the first and second carrier tapes Tc1, Tc2 are cut by a cutting device (not shown). The splicing device 21 cuts the first and second carrier tapes Tc1 and Tc2 at a cutting position Cp passing through the center of the circular feed hole Hc (see FIG. 2). The splicing device 21 transports the first and second carrier tapes Tc1 and Tc2 in a direction close to each other (the transport direction 35 in FIG. 2), and matches the semicircular feed holes Hc at the cutting position Cp with each other. And make it circular.

A splicing device (not shown) is provided at the center of the splicing device 21 to attach a splicing tape (not shown) to the first and second carrier tapes Tc1 and Tc2 fed along the tape transport path 32 and join them together. It has been. The joining device of the splicing device 21 splics the part that is abutted by the splicing tape. When the splicing operation is completed, the splicing device 21 opens the upper cover 21b and sets the spliced carrier tape (first and second carrier tapes Tc1, Tc2) to be taken out.

The reel bucket 22 is provided at a position close to the side surface 21d (see FIG. 3) on one side (the back side in FIG. 1) of the side surfaces 21c and 21d opposed to each other in the longitudinal direction of the main body portion 21a of the splicing device 21. Yes. The reel bucket 22 is provided with an accommodating portion 22a that individually accommodates each of the plurality of supply reels 25. The worker obtains a new supply reel 25 and stores it in each storage section 22a, for example, in a storage box or a reel storage place of a production line. In addition, the reel bucket 22 is provided with a support shaft 41 that supports the supply reel 25 used for splicing, and a holder portion 42 that restricts the first carrier tape Tc1 from being unwound from the supply reel 25. The detailed configuration of the reel bucket 22 will be described later.

The barcode reader 23 is, for example, a cordless handy type that performs wireless communication with the main body control unit 12. The operator performs an operation of reading the barcode 26 of the supply reel 25 taken out from the reel bucket 22 by the barcode reader 23 and the barcode (not shown) of the reel removed from the tape feeder. As a result, the main body control unit 12 executes so-called splicing verification, which checks whether or not the first carrier tape Tc1 (replenishment reel 25) containing correct electronic components has been prepared in the splicing operation.

The main body control unit 12 can communicate with a host computer (not shown) by a wireless LAN through an access point provided in a communication network of a production factory, for example. For example, the main body control unit 12 transmits information such as the read barcode 26 to the host computer. Based on the received information such as the barcode 26, the host computer determines whether or not the component code of the electronic component on which the splicing operation is to be performed is matched. When the main body control unit 12 receives information from the host computer that it is satisfactory, the main body control unit 12 displays that fact on the display device 24. After confirming the display on the display device 24, the worker performs the splicing work using the splicing device 21. As described above, the splicing unit 10 according to the present embodiment indicates that the wrong carrier tape (first carrier tape Tc1) having different types of electronic components is spliced by the process linked to the host computer such as the production line. It is possible to prevent.

The display device 24 includes a touch panel 24a having a display function and an input function. The display device 24 displays, on the touch panel 24a, the position information of the tape feeder to be spliced, the expected time of component shortage, the component information of the barcode 26 read by the barcode reader 23, and the like. In addition, the display device 24 includes an indicator lamp 24c that shines and notifies that the expected time of component shortage has been shortened. In addition, the main body control unit 12 includes a buzzer 12b that notifies the sound that the expected time of component shortage has shortened in conjunction with the indicator lamp 24c. The operations of the indicator lamp 24c and the buzzer 12b will be described later.

(2. Configuration of the reel bucket 22)
Next, the configuration of the reel bucket 22 will be described in detail with reference to FIGS. In the following description, as shown in FIGS. 3 to 5, the supply reel 25 taken out from the reel bucket 22 and placed in the holder portion 42 for performing splicing is replaced with another reel accommodated in the reel bucket 22. In order to distinguish from the supply reel 25, the description will be given as “supply reel 61”. FIG. 3 is a plan view of the splicing unit 10 as viewed from above, and shows a state where the supply reel 61 is disposed in the holder portion 42. FIG. 4 is a side view of the splicing unit 10 as viewed from the reel bucket 22 side, and shows a state in which the supply reel 61 is arranged in the holder portion 42. FIG. 5 is a side view of the reel bucket 22 as viewed from the holder portion 42 side.

Further, in the following description, the state shown in FIG. 4 is the state when the reel bucket 22 is viewed from the front, and description will be made using each direction (front and rear, left and right, up and down) shown in FIGS. In this case, a rear surface 51a (see FIG. 5) on the rear side of the reel bucket 22 is a surface facing the side surface 21d of the splicing device 21.

The reel bucket 22 includes a box portion 51 and a plurality of partition plates 52 that partition the box portion 51. The box portion 51 has a bottomed box shape with the top opened. The reel bucket 22 has a box portion 51 supported from below by a support member 28 fixed to the column portion 18. The support member 28 holds the box portion 51 (reel bucket 22) at a position separated from the splicing device 21 by a certain distance in the front-rear direction.

The partition plates 52 are provided in the box portion 51, and a plurality (9 in this embodiment) of the partition plates 52 are arranged in parallel along the left-right direction so as to face each other. Therefore, in the box part 51, ten accommodating parts 22a partitioned by the partition plate 52 are provided. A replenishment reel 25 can be inserted into each housing portion 22a from above.

Further, the supply reel 25 of the present embodiment includes a pair of discs 25a and a connecting shaft 25b. The pair of discs 25a have the same shape, and face each other in the left-right direction when accommodated in the accommodating portion 22a. The connecting shaft 25b has a substantially disk shape that is thicker than the disk 25a, and connects the centers of the pair of disks 25a to each other. The first carrier tape Tc1 is wound around the outer peripheral surface of the connecting shaft 25b. Further, the supply reel 25 is provided with a through hole 25d (see FIG. 5) penetrating the center of the pair of discs 25a and the connecting shaft 25b in the axial direction. Note that the configuration of the supply reel 25 of the present embodiment is an example, and can be changed as appropriate.

The upper part of the box part 51 and the partition plate 52 is formed in a shape inclined at a predetermined angle upward from the front to the rear. The supply reel 25 is accommodated in the accommodating portion 22 a in a state where a part of the pair of discs 25 a is exposed above the upper ends of the box portion 51 and the partition plate 52. Thereby, for example, the operator can easily take out the supply reel 25 from the housing portion 22a by holding the exposed portion of the disc 25a with his / her hand.

Among the two

side plates

51b and 51c facing each other in the left-right direction of the box portion 51, a support shaft 41 and a holder portion 42 are provided on the right side plate 51c. The support shaft 41 and the holder part 42 of this embodiment are provided integrally with the side plate 51c. For this reason, as will be described later, the side plate 51 c constitutes a part of the holder portion 42.

The support shaft 41 is provided at a position that is substantially the center of the side plate 51c in the front-rear direction and is close to the inclined upper end of the side plate 51c. Further, the support shaft 41 is provided at a position facing the bottom portion 42d of the holder portion 42 with an opening 42e of the holder portion 42 described later interposed therebetween in the vertical direction.

The support shaft 41 has a substantially cylindrical shape that protrudes from the plane on the right side of the side plate 51c and extends along a direction (left-right direction) orthogonal to the plane of the side plate 51c. The support shaft 41 is inserted from the tip end portion 41 a that protrudes into the through hole 25 d (see FIG. 5) of the supply reel 61. The support shaft 41 is inserted into the through-hole 25d so as to rotatably support the supply reel 61. The outer diameter of the tip portion 41 a is larger than the other portion of the support shaft 41. Therefore, the tip portion 41 a protrudes in a direction orthogonal to the axial direction of the support shaft 41. This makes it possible to prevent the supply reel 61 having the support shaft 41 inserted into the through hole 25d from coming off the support shaft 41 once.

The holder portion 42 is provided on the lower side of the side plate 51c, and includes a pair of

first side plates

42a and 42b, a second side plate 42c, and a bottom portion 42d. The pair of

first side plates

42a and 42b has a rectangular plate shape that is long in the up-down direction, and is fixed to the side plate 51c in a state where the planes are opposed to each other in the front-rear direction. Therefore, each plane of the pair of

first side plates

42a and 42b is parallel to the left-right direction and the up-down direction. The front side first side plate 42 a is arranged so as to be flush with the front surface 51 d of the box portion 51. Further, the first side plate 42b on the rear side is disposed so as to be flush with the back surface 51a of the box portion 51. Accordingly, the distance between the

first side plates

42a and 42b in the front-rear direction is the same as the length of the side plate 51c in the front-rear direction.

The second side plate 42c has a rectangular plate shape that is long in the front-rear direction, and is provided in a state in which the side plate 51c of the box portion 51 and the plane are opposed to each other in the left-right direction. The distance between the second side plate 42 c and the side plate 51 c in the left-right direction is slightly longer than the thickness of the supply reel 25. Both ends of the second side plate 42c in the front-rear direction are connected to the

first side plates

42a and 42b.

The bottom portion 42d is formed in a plate shape that closes the space surrounded by the

first side plates

42a and 42b, the second side plate 42c, and the side plate 51c from below. The bottom portion 42d is provided at a position close to the lower end portion of the side plate 51c (the bottom portion 51e of the box portion 51) in the vertical direction.

As described above, the holder portion 42 has a bottomed box shape surrounded by the

first side plates

42a and 42b, the second side plate 42c, the side plate 51c, and the bottom portion 42d, and has an opening 42e at the top. Therefore, the side plate 51 c of this embodiment constitutes the holder part 42. In this case, the side plate 51c functions as a side plate in the present application. The holder portion 42 can insert the supply reel 25 into the enclosed space from the opening 42e. The opening 42e has a substantially rectangular shape that is long in the front-rear direction when viewed from above (see FIG. 3). The second side plate 42c and the side plate 51c are held on the side surface (disk 25a) of the supply reel 61 inserted into the holder portion 42, and the supply reel 61 moves in the left-right direction (the axial direction of the supply reel 61). To regulate.

(3. Arrangement of supply reel 61)
Next, the arrangement of the supply reel 61 will be described. For example, the worker confirms the display on the display device 24, and takes out the supply reel 61 that can be used for splicing from the housing portion 22 a of the reel bucket 22. For example, as shown by an arrow 63 in FIG. 4, the worker inserts the taken-out supply reel 61 into the opening 42 e of the holder portion 42 obliquely from the upper right. The operator inserts the supply reel 61 deeply toward the bottom 42 d of the holder portion 42 while inserting the support shaft 41 into the through hole 25 d of the supply reel 61.

As shown in FIG. 5, the distance L1 between the support shaft 41 and the bottom part 42d of the holder part 42 is longer than the radius R1 of the disk 25a of the supply reel 61. For this reason, the supply reel 61 is separated from the bottom portion 42 d in a state where the supply reel 61 is inserted into the holder portion 42 and supported by the support shaft 41. The lower portion 61a of the supply reel 61 is arranged with a predetermined gap between the lower portion 61a and the inner wall surface 42f of the bottom portion 42d. Similarly, the supply reel 61 is disposed with a predetermined gap between each of the

first side plates

42a and 42b, the second side plate 42c, and the inner wall surface 42f of the side plate 51c. In other words, the support shaft 41 supports the supply reel 61 in the holder portion 42 with a gap provided between the support shaft 41 and the inner wall surface 42 f of the holder portion 42.

As shown in FIGS. 4 and 5, the pair of

first side plates

42a and 42b are arranged in the radial direction of the supply reel 61 (disk 25a) in a state where the supply reel 61 is inserted into the holder portion 42. It is arranged outside the one carrier tape Tc1 and at a position facing the first carrier tape Tc1. Here, for example, when the unused supply reel 61 is used for splicing, the first carrier tape Tc1 may spread outward in the radial direction of the disc 25a when the tape that stops the first carrier tape Tc1 is removed. . In this case, even if the first carrier tape Tc1 is unwound and spreads, as shown by an arrow 64 in FIG. 5, the first carrier tape Tc1 is caught by the first side plate 42a and the second side plate 42c and is restricted from moving outward in the radial direction. . As a result, the first carrier tape Tc1 is prevented from being unnecessarily unwound.

Next, the operator rotates the supply reel 61 around the support shaft 41 while being inserted into the holder portion 42, and pulls out the first carrier tape Tc1. Also at this time, the holder portion 42 suppresses the first carrier tape Tc1 from spreading outward in the radial direction. As shown in FIG. 3, the operator inserts the leading end of the drawn first carrier tape Tc1 into the insertion port 31b of the splicing device 21. When detecting the insertion of the first and second carrier tapes Tc1 and Tc2, the splicing device 21 automatically starts splicing.

Further, as shown in FIG. 3, the support shaft 41 is disposed at the same position as the insertion port 31b in the left-right direction, and is disposed opposite to the insertion port 31b in the front-rear direction. As shown in FIG. 4, the support shaft 41 is disposed at a position shifted downward by a predetermined distance from the position of the insertion port 31 b in the vertical direction. As shown in FIG. 3, the transport direction 66, which is the direction of transporting the first carrier tape Tc1 drawn backward from the supply reel 61 to the insertion port 31b, is the first carrier tape Tc1 on the tape transport path 32. It is along the conveyance direction 35 which is a direction to convey by. The first carrier tape Tc1 is linear in the conveyance path from the supply reel 61 to the tape conveyance path 32 through the insertion port 31b. Thereby, generation | occurrence | production of a twist etc. are suppressed by 1st carrier tape Tc1.

(4. Notification by indicator lamp 24c and buzzer 12b)
Next, notification processing by the indicator lamp 24c and the buzzer 12b will be described. FIG. 6 shows an example of a display screen when the touch panel 24a of the display device 24 is viewed from the front. An information display unit 71 for displaying information such as a collation error due to splicing verification is provided at the center of the touch panel 24a. Below the information display section 71, a barcode display section 72 for displaying the number of the barcode 26 read by the barcode reader 23 is provided.

Also, on the upper right of the touch panel 24a, a radio wave intensity display unit 73 for displaying the intensity of a received radio wave received from an access point such as a production factory is provided. A cancel button 74 is provided below the information display unit 71. The cancel button 74 is used, for example, when it is desired to stop the processing during the above-described splicing verification.

Further, on the left side of the information display section 71, a notice display section 75 is provided for showing a notice of a tape feeder (not shown) that is expected to run out of parts. The touch panel 24a of this embodiment is provided with five notice display parts 75. The notice display section 75 displays information about a tape feeder that is expected to be out of parts received from a host computer (not shown), that is, loaded with the second carrier tape Tc2 to be replenished. For example, the top notice display section 75 includes a module number “2” for identifying the electronic component mounting machine, a slot number “4” indicating the mounting position of the tape feeder to be replenished in the electronic component mounting machine, The estimated time “00:33:30” until the product runs out is displayed. In this case, the notice display unit 75 displays that the second carrier tape Tc2 of the tape feeder mounted in the slot number “4” of the module number “2” will run out of components after 33 minutes and 30 seconds.

For example, the main body control unit 12 collects information about the second carrier tape Tc2 (tape feeder) that is expected to be out of components from the host computer for 10 cases. The main body control unit 12 periodically executes processing to be acquired. The main body control unit 12 displays, on the notice display unit 75, five items of the acquired ten pieces of information that have a short estimated time until a component shortage occurs. Further, the main body control unit 12 causes the notice display unit 75 to display the five cases to be displayed in order from the top of the screen to the bottom in order from the shorter expected time. Therefore, as shown in FIG. 6, the estimated time displayed on the notice display unit 75 increases in order from the top to the bottom of the screen.

Here, if there is a sufficient time until the time when the next part is expected to be cut, that is, the time when the next splicing work needs to be started (the time in the example of FIG. 6 is 30 minutes or more), the worker In some cases, it may be desirable to perform other operations away from the splicing unit 10. However, if the expected time elapses, parts may run out and the production line may be stopped. For this reason, for example, the worker needs to perform another work while paying attention to the time so that the expected time (33 minutes 30 seconds) of the shortest part cut-off does not elapse.

On the other hand, in the splicing unit 10 of this embodiment, the indicator lamp 24c that shines and notifies that the expected time of part shortage has been shortened, and the buzzer 12b that notifies the sound that the expected time of part shortage has been shortened. And. For example, when the shortest expected part cut time (33 minutes and 30 seconds) is shortened to 5 minutes, the main body control unit 12 turns on the indicator lamp 24c and executes a process of sounding the buzzer 12b. The splicing unit 10 may have a configuration in which the timing notified by the indicator lamp 24c or the like can be changed according to the operation of the touch panel 24a.

As a result, the worker who is performing other work on the production line or the like recognizes that the time to start the next splicing work is approaching due to the light of the indicator lamp 24c and the sound of the buzzer 12b. It can be confirmed at a place away from 10. Also, the worker can concentrate on other work until receiving a notification without worrying about the passage of time. As a result, it is possible to increase work efficiency and reduce the number of workers required for the production line.

Note that the means for notifying the worker that the estimated time of part shortage is approaching is not limited to the indicator lamp 24c and the buzzer 12b described above. For example, the splicing unit 10 may be configured to notify the worker's mobile terminal that the expected time is approaching.

(5. Effects of the configuration of the first embodiment)
The splicing unit 10 according to the first embodiment described above includes a splicing device 21 that splices the first carrier tape Tc1 (carrier tape) wound around the supply reel 61 and the second carrier tape Tc2 (carrier tape to be supplied). A support shaft 41 (support portion) that rotatably supports the supply reel 61, and a first carrier tape Tc 1 that is unfastened from the supply reel 61 supported by the support shaft 41 is arranged in the radial direction of the supply reel 61. And a holder portion (restricting portion) for restricting movement toward the outside.

According to this, the supply reel 61 is rotatably supported by the support shaft 41 (support portion). Therefore, before the splicing operation, the first carrier tape Tc1 unwound from the supply reel 61 can be easily pulled out and set in the splicing device 21 while the supply reel 61 is rotated. At this time, the first carrier tape Tc1 that has been unwound from the supply reel 61 is restricted by the holder portion 42 (restriction portion) from moving outward in the radial direction of the supply reel 61, and therefore can be unnecessarily unwound. It is suppressed. As a result, for example, after the splicing is completed, the operator does not need to rewind the first carrier tape Tc1 that has been unnecessarily unwound onto the supply reel 61, and the work efficiency can be improved.

Furthermore, the supply reel 61 has a substantially disk shape. The restricting portion includes a box-shaped holder portion 42 having an opening 42e into which a part of the supply reel 61 can be inserted.

According to this, the supply reel 61 has a substantially disc shape, and is accommodated in the holder portion 42 in a state where a part thereof is inserted from the opening 42 e of the holder portion 42. Then, the movement of the first carrier tape Tc1 unwound from the supply reel 61 is restricted by the holder portion 42.

Furthermore, the supply reel 61 is provided with a through hole 25d in the center of a substantially disk shape. The support portion includes a support shaft 41 that can be inserted into the through hole 25 d of the supply reel 61. The support shaft 41 supports the supply reel 61 in the holder portion 42 with a gap provided between the support shaft 41 and the inner wall surface 42 f of the holder portion 42.

According to this, the support shaft 41 rotatably supports the supply reel 61 by being inserted into the through hole 25d provided in the center of the supply reel 61. The support shaft 41 supports the supply reel 61 in the holder portion 42 with a gap provided between the support shaft 41 and the inner wall surface 42 f of the holder portion 42. As a result, the support shaft 41 can reduce the contact between the supply reel 61 and the holder portion 42, and can easily rotate the supply reel 61 inserted into the holder portion 42. Accordingly, while the movement of the first carrier tape Tc1 is restricted by the holder portion 42, the supply reel 61 can be rotated around the support shaft 41 so that the first carrier tape Tc1 can be easily pulled out.

Further, the splicing device 21 includes an insertion port 31b for inserting the first carrier tape Tc1 (carrier tape) of the supply reel 61, and a tape conveyance path 32 for conveying the first carrier tape Tc1 inserted from the insertion port 31b. Prepare. The support shaft 41 (support portion) is such that the first carrier tape Tc1 drawn from the supply reel 61 is linear in the transport path from the supply reel 61 through the insertion port 31b to the tape transport path 32. The supply reel 61 is supported so that

According to this, the first carrier tape Tc1 of the supply reel 61 is inserted on the tape transport path 32 with the tip portion inserted from the insertion port 31b. The first carrier tape Tc1 is linearly arranged in the conveyance path from the base end portion on the supply reel 61 side through the insertion port 31b to the distal end portion arranged on the tape conveyance path 32. Thereby, it can suppress that twist etc. generate | occur | produce in 1st carrier tape Tc1, and can suppress that 1st carrier tape Tc1 can be unwound from the supply reel 61.

Furthermore, the splicing unit 10 further includes a reel bucket 22 that can accommodate a plurality of supply reels 61. The support shaft 41 (support part) and the holder part 42 (regulation part) are provided integrally with the reel bucket 22.

According to this, the splicing unit 10 can accommodate and carry the plurality of supply reels 61 together in the reel bucket 22. An operator can use each supply reel 61 to perform splicing continuously on a plurality of supply target carrier tapes (second carrier tape Tc2). In addition, since the first carrier tape Tc1 can be prevented from being unnecessarily unwound from the supply reel 61 in a plurality of operations related to splicing, the operator can increase the work efficiency and perform splicing operations one after another. . Furthermore, by providing the support shaft 41 (support portion) and the holder portion 42 (regulation portion) integrally with the reel bucket 22, the number of parts constituting the splicing unit 10 can be reduced.

(6. Second embodiment)
Next, a second embodiment of the splicing unit of the present invention will be described with reference to FIG. FIG. 7 shows the holder part 142 of the second embodiment.
