[0067] Hereinafter, the embodiments will be described in detail with appropriate reference to the accompanying drawings. However, sometimes, detailed description necessary above is omitted. For example, sometimes, detailed description of matters already well known, repeated description of substantially the same structure is omitted. This is to avoid the following description from becoming unnecessarily lengthy and to make it easy for those skilled in the art to understand.

[0068] Note that the inventors provide the accompanying drawings and the following description in order for those skilled in the art to fully understand the present disclosure, and do not intend to limit the subject matter described in the technical solution by them.

[0069] Hereinafter, a tape cutting apparatus according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0070] Figure 1 is a perspective view of a tape cutting apparatus according to an embodiment of the present disclosure. In addition, Figure 2A and Figure 2B is a perspective view of the front end portions of a first carrier tape and a second carrier tape cut by the tape cutting apparatus. Also, Figure 3A is a perspective view showing a tape setting position of a carrier tape. Also, Figure 3B is a perspective view showing a tape cutting position of a carrier tape.

[0071] The tape cutting apparatus 10 according to the present embodiment is configured to cut various carrier tapes of various kinds and various widths and thicknesses as shown in Figure 2A and Figure 2B Figure 2A The first carrier tape 200 shown in is a carrier tape having the smallest tape width among a plurality of carrier tapes that can be cut by the tape cutting apparatus 10 of the present embodiment. In addition, Figure 2B ​The second carrier tape 300 shown is the carrier tape with the largest tape width. For example, the tape width of the former is 8 mm, and the tape width of the latter is 104 mm.

[0072] As shown in Figure 2A and Figure 2B The first carrier tape 200 and the second carrier tape 300 each have a base tape 202, 302, and a cover tape 204, 304 attached to the base tape 202, 302.

[0073] The base tapes 202, 302 are provided with a plurality of member grooves 202a, 302a in the form of embossing that house members. The plurality of member grooves 202a, 302a are arranged in the length direction of the base tapes 202, 302. In addition, a plurality of feed holes 202b, 302b in the form of through holes arranged in the length direction are formed in the base tapes 202, 302. Note that, as shown in Figure 2A In the case of the first carrier tape 200 with a small tape width, the plurality of feed holes 202b are formed only in one side portion in the width direction, as shown in Figure 2B In the case of the second carrier tape 300 with a large tape width, the plurality of feed holes 302b are formed in both side portions in the width direction with the member grooves 302a in between, as shown in

[0074] The cover tapes 204, 304 are attached to the base tapes 202, 302 in a manner to cover the openings of the member grooves 202a, 302a.

[0075] The tape cutting apparatus 10 of the present embodiment cuts the first carrier tape 200 and the second carrier tape 300 in a manner that the leading ends 204a, 304a in the length direction of the cover tapes 204, 304 are located a predetermined distance D forward of the leading ends 202c, 302c of the base tapes 202, 302, as shown in Figure 2A and Figure 2B Specifically, the tape cutting apparatus 10 first performs a first cutting process that cuts both the base tapes 202, 302 and the cover tapes 204, 304. In addition, the tape cutting apparatus 10 performs a second cutting process that cuts only the base tapes 202, 302 at a position that is separated by the predetermined distance D from the cut surface of the new base tapes 202, 302 formed by the first cutting process. The first cutting process and the second cutting process are performed simultaneously, the leading ends 204a, 304a of the cover tapes 204, 304 are formed by the first cutting process, and the leading ends 202c, 302c of the base tapes 202, 302 are formed by the second cutting process.

[0076] Details of the tape cutting apparatus 10 of the present embodiment will be described later, as shown in Figure 3AAs shown, the first carrier tape 200 is provided outside the housing 12 in front of the housing 12. In addition, the tape cutting apparatus 10 is configured to cut the first carrier tape 200 inside the housing 12. Note that, in Figure 3A and Figure 3B , the first carrier tape 200 is shown as an example of a variety of carrier tapes that can be cut by the tape cutting apparatus 10, but other types of carrier tapes are equally possible.

[0077] Specifically, the tape cutting apparatus 10 is configured to be able to carry a variety of carrier tapes including the first carrier tape 200 from a tape setting position P1 shown in Figure 3A to a tape cutting position P2 shown in Figure 3B . Specifically, at the tape setting position P1, the carrier tape is set to the tape cutting apparatus 10 in such a way that the length direction thereof coincides with the left-right direction of the tape cutting apparatus 10. The carrier tape set at the tape setting position P1 is moved in the width direction thereof, in the case of the present embodiment, in the front-rear direction of the tape cutting apparatus 10, to the tape cutting position P2 located behind the tape setting position P1 and inside the housing 12. When disposed at the tape cutting position P2, the carrier tape penetrates the housing 12 in the left-right direction of the housing 12. That is, the carrier tape passes through the opening 12a provided in the housing 12 at the tape cutting position P2, and is located outside the opening 12a at the tape setting position P1.

[0078] Note that the opening 12a is present on both the right side surface and the left side surface of the housing 12.

[0079] The structure of the tape cutting apparatus 10 will be described in detail from here.

[0080] Figure 4 is a perspective view of the main body portion of the tape cutting apparatus. In addition, Figure 5 is an exploded perspective view of the main body portion of the tape cutting apparatus.

[0081] As shown in Figure 4 and Figure 5 , the tape cutting apparatus 10 has a main body portion 14. Note that the main body portion 14 is a portion obtained by removing the housing cover 16, the legs 18, and the like from the housing 12 shown in Figure 1

[0082] As shown in Figure 4 and Figure 5 , the tape cutting apparatus 10 has a tape holding unit 20 that holds a carrier tape.

[0083] Figure 6 is a perspective view of the tape holding unit. In addition, Figure 7 is a plan view of the tape holding unit. Furthermore, Figure 8 is an exploded perspective view of the tape holding unit. Moreover, Figure 9A ​is a perspective view of a tape holding unit that holds the state of the first carrier tape. Also, Figure 9B is a perspective view of a tape holding unit that holds the state of the second carrier tape.

[0084] As shown in Figure 9A and Figure 9B , the tape holding unit 20 is configured to be able to hold a plurality of carrier tapes including the first carrier tape 200 and the second carrier tape 300.

[0085] Specifically, in the case of the present embodiment, the tape holding unit 20 holds a plurality of carrier tapes including the first carrier tape 200 and the second carrier tape 300 in a manner in which the length direction of the plurality of carrier tapes coincides with the left-right direction of the tape cutting apparatus 10. In addition, the tape holding unit 20 holds the plurality of carrier tapes in a state in which the cover tapes (the cover tape 204 of the first carrier tape 200 and the cover tape 304 of the second carrier tape 300) face upward. That is, in the case of the present embodiment, the width direction of the carrier tapes coincides with the front-rear direction of the tape cutting apparatus 10, the length direction of the carrier tapes coincides with the left-right direction of the tape cutting apparatus 10, and the thickness direction of the carrier tapes coincides with the up-down direction of the tape cutting apparatus 10.

[0086] In addition, the tape holding unit 20 is supported in a movable manner in the plate-shaped intermediate base member 22 in the main body portion 14 as shown in Figure 5 . Specifically, the tape holding unit 20 includes a unit base member 24 that is installed to the intermediate base member 22 in a movable manner in the front-rear direction of the tape cutting apparatus 10 via a slide rail 26. Due to this, the tape holding unit 20 moves in parallel between a tape cutting position P2 for cutting the carrier tape and a tape setting position PI for setting the carrier tape to the tape holding unit 20.

[0087] Also, the tape holding unit 20 is configured in a manner in which a plurality of carrier tapes including the first carrier tape 200 and the second carrier tape 300 are supported at both sides in the width direction thereof. That is, in the case of the first carrier tape 200 and the second carrier tape 300, the tape holding unit 20 supports the outer side portions in the width direction with respect to the embossed member grooves 202a, 302a.

[0088] Figure 10 is a perspective view of a tape holding unit that holds the state of the first carrier tape. Also,

[0089] As shown in Figure 7 , Figure 8 and Figure 10As shown, the belt holding unit 20 includes a plurality of first belt support members 28 that support one side portion of the width direction of various carrier belts. The first belt support members 28 are spaced apart in the left-right direction of the belt cutting device 10 and have a first belt support surface 28a that contacts the base belt in the carrier belt to support the belt. Furthermore, each of the first belt support members 28 is plate-shaped and fixed to the unit base member 24 via a fixing block 30. It should be noted that, in this embodiment, the first belt support members 28 support the front portion of the carrier belt in the state held in the belt holding unit 20.

[0090] In addition, such as Figure 10 As shown, the fixing block 30, on which the first belt support member 28 is mounted, is provided with a plurality of first positioning pins 32 that engage with the feed hole of the carrier belt. The first positioning pins 32 are arranged such that they protrude from the first belt support surface 28a of the first belt support member 28. Thus, as... Figure 9A and Figure 9B As shown in the first carrier belt 200 and the second carrier belt 300, the first locating pin 32 engages with a feed hole formed on one side of the carrier belt supported on the first belt support surface 28a in the width direction. The movement of the carrier belt in the width direction and length direction (i.e., the front-back direction and the left-right direction of the belt cutting device 10) is restricted when the first locating pin 32 is engaged with the feed hole.

[0091] like Figure 9A and Figure 9B As shown in the first carrier belt 200 and the second carrier belt 300, the movement of the carrier belt in the thickness direction (i.e., the vertical direction of the belt cutting device 10) when the first positioning pin 32 is engaged with the feed hole is restricted by the belt pressing member 34.

[0092] Specifically, such as Figure 10 As shown, the belt pressing member 34 has a belt pressing surface 34a that is spaced apart from the first belt support surface 28a of the first belt support member 28 and faces it. In this embodiment, the belt pressing surface 34a is hemispherical. It should be noted that, depending on the type of carrier belt, i.e., depending on the thickness of the carrier belt, the belt pressing surface 34a does not contact the carrier belt. As a countermeasure, the lowest point of the belt pressing surface 34a is located below the apex of the first positioning pin 32 (see reference). Figure 11A Therefore, regardless of the thickness of the carrier tape, the first positioning pin 32 will not fall out of its feed hole.

[0093] It should be noted that when the belt pressing member 34 is present on the first belt support surface 28a of the first belt support member 28, the carrier belt cannot be placed on the first belt support surface 28a, that is, the first positioning pin 32 cannot be inserted into the feed hole. Therefore, the belt pressing member 34 retracts from above the first belt support surface 28a of the first belt support member 28. Specifically, as... Figure 8 and Figure 10 As shown, the belt pressing member 34 is mounted on the fixing block 30 via the sliding guide 36 in a manner that allows it to move in the front-rear direction of the belt cutting device 10. Therefore, when the carrier belt is placed on the first belt support surface 28a, the belt pressing member 34 can retract forward from above the first belt support surface 28a. It should be noted that, in this embodiment, the movement of the belt pressing member 34 in the front-rear direction is performed manually by the user.

[0094] In this embodiment, the first positioning pin 32 can retract downward relative to the first support surface 28a of the first support member 28.

[0095] Figure 11A This is a partial cross-sectional view showing the first locating pin in the first engaged position. Figure 11B This is a partial cross-sectional view showing the first locating pin in the first disengaged position.

[0096] like Figure 11A and Figure 11B As shown, the first locating pin 32 is positioned at a first engagement position protruding from the first belt support surface 28a of the first belt support member 28. Figure 11A The position shown) and the first engagement / disengagement position located below the first belt support surface 28a ( Figure 11B The manner in which the movement is relative to the first belt support member 28 is set between the positions shown.

[0097] Specifically, in the location Figure 11A When the first engagement position is shown, the first positioning pin 32 enters as shown. Figure 9A and Figure 9B The first carrier belt 200 and the second carrier belt 300, as shown, are placed in the feed hole of the carrier belt on the first carrier belt support surface 28a of the first carrier belt support member 28. Additionally, in the area located... Figure 11B When the first engagement / disengagement position is shown, the first positioning pin 32 is located outside the feed hole of the carrier belt placed on the first belt support surface 28a of the first belt support member 28.

[0098] In such Figure 11BWhen the first positioning pin 32 is in the first engagement / disengagement position as shown, the carrier belt placed on the first belt support surface 28a of the first belt support member 28 can move in its length direction (in the left-right direction of the belt cutting device 10 in this embodiment). Thus, the user can... Figure 11A The carrier belt is removed from the belt holding unit 20 with the pressing member 34 present above the first belt support surface 28a of the first belt support member 28 as shown.

[0099] It should be noted that, in this embodiment, the first engagement position of the plurality of first positioning pins 32 ( Figure 11A ) and the first card release position ( Figure 11B The movement between the multiple first positioning pins 32 is simultaneous and performed manually by the user. Figure 8 , Figure 11A ,and Figure 11B As shown, it is mounted on the positioning pin drive rod 38. The positioning pin drive rod 38 is supported on a plurality of fixed blocks 30 in a manner that allows it to swing around a swing center line C1 extending in the left-right direction along the belt cutting device 10. A plurality of first positioning pins 32 are provided at the rear end 38a of the positioning pin drive rod 38.

[0100] When the user lifts the front end 38b of the pin drive lever 38 upwards, multiple first positioning pins 32 simultaneously move from the first engaging position ( Figure 11A ) Towards the first engagement release position ( Figure 11B The first positioning pins 32 move downwards. It should be noted that the rear end 38a of the positioning pin drive rod 38 is subjected to an upward force via the spring 40. Therefore, when the positioning pin drive rod 38 is not operated by the user, the plurality of first positioning pins 32 remain in the first engaged position. Furthermore, when the first positioning pin 32 swings around the swing center line C1, the first positioning pin 32 engages with the feed hole of the carrier belt, and the carrier belt moves downwards together with the first positioning pin 32. However, this downward movement of the carrier belt is restricted by the first belt support member 28. That is, the first belt support surface 28a of the first belt support member 28 is fixed, so even if the first positioning pin 32 moves downwards while in contact with the feed hole, the carrier belt cannot move.

[0101] like Figure 6~Figure 8 As shown, the belt holding unit 20 includes a second belt support member 42 and a third belt support member 44 supporting the other side portion of the belt in the width direction. Figure 7 As shown, the second belt support member 42 and the third belt support member 44 are positioned opposite the first belt support member 28 in the front-rear direction of the belt cutting device 10. Details of the second belt support member 42 and the third belt support member 44 will be explained below.

[0102] Figure 12is a perspective view showing the second tape supporting member and the third tape supporting member. In addition, Figure 13 is an exploded perspective view of the second tape supporting member and the third tape supporting member. Moreover, Figure 14 is a perspective view of the second tape supporting member showing a state after the tape pressing member is moved above the second positioning pin.

[0103] As shown in Figure 12 and Figure 13 , the second tape supporting member 42 and the third tape supporting member 44 are block-shaped and have second tape supporting surfaces 42a and third tape supporting surfaces 44a that support the other side portion in the width direction of the various kinds of tape. The second tape supporting member 42 and the third tape supporting member 44 are provided at intervals in the left-right direction of the tape cutting apparatus 10 and contact the base tape in the tape to support the tape. Note that in the case of the present embodiment, the second tape supporting member 42 and the third tape supporting member 44 support the portion of the tape on the rear side of the tape cutting apparatus 10 in the state in which the tape is held by the tape holding unit 20.

[0104] As shown in Figure 13 , the second tape supporting member 42 has a block 46 and a cover 48 that is attached to the front surface of the block 46. Note that the second tape supporting surface 42a is constituted by the upper surface of the block 46 and the upper surface of the cover 48. In addition, the second tape supporting member 42 is provided with a second positioning pin 50 that engages with the feed hole of the tape.

[0105] The second positioning pin 50 engages with the feed hole on the other side portion in the width direction of the tape on the second tape supporting surface 42a of the second tape supporting member 42 (the portion on the rear side of the tape cutting apparatus 10 in the case of the present embodiment).

[0106] Specifically, with respect to a tape such as the second tape 300 shown in Figure 2B that has a feed hole on both sides in the width direction, the second positioning pin 50 engages with the feed hole on the other side portion in the width direction of the tape.

[0107] In contrast, with respect to a tape such as the first tape 200 shown in Figure 2A that has a feed hole only on one side portion in the width direction (the portion on the front side of the tape cutting apparatus 10 in the case of the present embodiment), there is no feed hole on the other side portion in the width direction that engages with the second positioning pin 50. Therefore, the second positioning pin 50 does not engage with the feed hole of such a tape.

[0108] Note that in the case of the present embodiment, the second tape supporting member 42 has the second positioning pin 50 that engages with the feed hole of the tape, and in contrast, the third tape supporting member 44 does not have a positioning pin that engages with the tape.

[0109] As for the tape carrier as shown in Figure 2B the tape carrier having the feeding hole on the other side portion in the width direction is engaged with the feeding hole on the other side portion in the width direction of the tape carrier by the second positioning pin 50, so that the movement of the tape carrier in the width direction and the length direction (in the case of the present embodiment, the front-rear direction and the left-right direction of the tape cutting device 10) is restricted.

[0110] As for the tape carrier as shown in Figure 9B the tape carrier having the feeding hole on the other side portion in the width direction is engaged with the feeding hole on the other side portion in the width direction of the tape carrier by the second positioning pin 50, so that the movement of the tape carrier in the width direction and the length direction (in the case of the present embodiment, the front-rear direction and the left-right direction of the tape cutting device 10) is restricted.

[0111] Figure 14 is a perspective view showing the state of the tape pressing member after retreating from above the second positioning pin.

[0112] When the tape pressing member 52 exists on the second tape supporting surface 42a of the second tape supporting member 42, the tape carrier cannot be placed on the second tape supporting surface 42a, that is, the second positioning pin 50 cannot be inserted into the feeding hole. Therefore, as shown in Figure 14 the tape pressing member 52 retreats from above the second tape supporting surface 42a of the second tape supporting member 42. In the case of the present embodiment, the tape pressing member 52 retreats toward the rear of the tape cutting device 10.

[0113] Specifically, as shown in Figure 13 the tape pressing member 52 is installed to the block 46 of the second tape supporting member 42 via the slide rail 54 in a manner that it can move in the front-rear direction of the tape cutting device 10. Thus, when the tape carrier is placed on the second tape supporting surface 42a, the tape pressing member 52 can retreat from above the second tape supporting surface 42a toward the rear. Note that in the case of the present embodiment, the movement of the tape pressing member 52 in the front-rear direction is performed manually by the user.

[0114] Note that as shown in Figure 12 and Figure 13 the same tape pressing member 56 as the tape pressing member 52 is also provided to the third tape supporting member 44. However, since the third tape supporting member 44 does not have the positioning pin engaged with the feeding hole, the tape pressing member 56 is fixed to the third tape supporting member 44 in a manner that it cannot move.

[0115] In addition, the second positioning pin 50 can also retreat downward relative to the second tape supporting surface 42a of the second tape supporting member 42, like the first positioning pin 32.

[0116] Figure 15A is a front view of the second tape supporting member in a state in which the second positioning pin is located at the second engagement position, and Figure 15B is a front view of the second tape supporting member in a state in which the second positioning pin is located at the second engagement release position. Also, Figure 16 is a side view of the second tape supporting member in a state in which the second positioning pin is located at the second engagement position. Note that, Figure 15A and Figure 15B illustrates the second tape supporting member 42 in a state in which the cover 48 is removed.

[0117] As shown in Figure 15A , Figure 15B and Figure 16 , the second positioning pin 50 is provided to the second tape supporting member 42 in a manner so as to be movable between a second engagement position (position shown by A) protruding from a second tape supporting surface 42a of the second tape supporting member 42 and a second engagement release position (position shown by B) located below the second tape supporting surface 42a. Figure 14 A. Figure 14 B.

[0118] Specifically, in the case of the present embodiment, as shown in Figure 13 , a swing block 58 that swings about a swing center line C2 extending in the width direction of the tape (in the case of the present embodiment, the front-rear direction of the tape cutting apparatus 10) is provided between the block 46 of the second tape supporting member 42 and the cover 48. The second positioning pin 50 is provided to this swing block 58. Also, the swing block 58 is urged to the left by a torsion spring 59 so as to maintain the second positioning pin 50 at the second engagement position (position shown by A). Therefore, when the tape that is in a state in which the feed hole is engaged to the second positioning pin 50 is moved to the right, the second positioning pin 50 moves from the second engagement position to the second engagement release position (position shown by B). As a result, it is possible to take out the tape from the tape holding unit 20 in a state in which the tape pressing member 52 is present above the second positioning pin 50. Figure 14 A. Figure 14 B.

[0119] Also, in the case of the present embodiment, the second tape supporting member 42 and the third tape supporting member 44 are provided to the tape holding unit 20 in a manner so as to be relatively movable in the width direction of the tape (in the case of the present embodiment, the front-rear direction of the tape cutting apparatus 10) with respect to the first tape supporting member 28. Specifically, in the case of the present embodiment, the first tape supporting member 28 is fixed to the tape holding unit 20 as described above, and the second tape supporting member 42 and the third tape supporting member 44 are provided to the tape holding unit 20 in a manner so as to be movable in the front-rear direction of the tape cutting apparatus 10. Thus, as shown in Figure 9A and Figure 9BThe first carrier tape 200 and the second carrier tape 300, which are different in width, are supported at both sides in the width direction by the first tape support member 28, the second tape support member 42, and the third tape support member 44.

[0120] In the case of the second carrier tape 300 provided with the feeding hole at both sides in the width direction, the position adjustment of the second tape support member 42 and the third tape support member 44 is performed before the carrier tape is set to the tape holding unit 20. Specifically, the positions of the second tape support member 42 and the third tape support member 44 in the width direction of the carrier tape (in the front-rear direction of the tape cutting apparatus 10 in the case of the present embodiment) are adjusted in correspondence with the carrier tape set to the tape holding unit 20. Figure 2B

[0121] In the case of the present embodiment, first, the second tape support member 42 and the third tape support member 44 are connected via the first shielding members 60, 62 and the "コ" shaped link member 64 connecting the first shielding members 60, 62 as shown in Figure 8 The first shielding member 60 extends rearward from the second tape support member 42, and the first shielding member 62 extends rearward from the third tape support member 44. The rear side portions of the first shielding members 60, 62 are connected by the link member 64. Thus, the position adjustment of the second tape support member 42 and the third tape support member 44 can be performed simultaneously. Note that the functions of the first shielding member 60 and the second shielding member 62 will be described later.

[0122] In the case of the present embodiment, as shown in Figure 12 and Figure 13 As the locking mechanism for fixing the third tape support member 44 at a position corresponding to the carrier tape set to the tape holding unit 20, the third tape support member 44 is provided with a locking pin 66.

[0123] Figure 17A is a view showing a locked state of the third tape support member with respect to the unit base member of the tape holding unit by the locking pin. In addition, Figure 17B is a view showing a state where the locking of the third tape support member with respect to the unit base member of the tape holding unit by the locking pin is released.

[0124] As shown in Figure 17A and Figure 17B The locking pin 66 is provided to the third tape support member 44 in a manner that it can move in the thickness direction of the carrier tape (in the up-down direction of the tape cutting apparatus 10 in the case of the present embodiment). The plurality of positioning holes 24a, which are through holes, engaged with the locking pin 66 are provided to the unit base member 40 of the tape holding unit 20. Figure 7 ​As shown, the unit base member 24 with the retaining unit 20 is formed. When the locking pin 66 is engaged in one positioning hole 24a, the other side portion of the carrier tape corresponding to the positioning hole 24a in the width direction (in this embodiment, the portion on the rear side of the tape cutting device 10) is supported on the second tape support surface 42a of the second tape support member 42 and the third tape support surface 44a of the third tape support member 44. That is, in order to enable the second tape support member 42 and the third tape support member 44 to support various carrier tapes with different widths, a plurality of positioning holes 24a are formed at positions corresponding to the aforementioned widths.

[0125] It should be noted that, in this embodiment, the positioning of the second belt support member 42 and the third belt support member 44 is performed by the user. However, regarding the positioning hole 24a, when the third belt support member 44 is positioned above, the user cannot see the positioning hole 24a. That is, the user cannot confirm that the locking pin 66 is located above the positioning hole 24a corresponding to the carrier belt that will be cut next.

[0126] Therefore, as Figure 7 and Figure 8 As shown, a positioning guide rail member 68 for positioning the second belt support member 42 and the third belt support member 44 is installed on the unit base member 24. Furthermore, a positioning roller 70 that rolls on the positioning guide rail member 68 is installed on the first shielding members 60 and 62. It should be noted that... Figure 8 The positioning roller 70 installed on the first shielding member 62 is not visible in the image.

[0127] The positioning guide rail member 68 has a plurality of "V"-shaped grooves 68a for engaging the positioning roller 70. The arrangement of these grooves 68a corresponds to the arrangement of the positioning holes 24a. Therefore, when the positioning roller 70 is engaged in one groove 68a, the locking pin 66 is positioned above the corresponding positioning hole 24a. Thus, the user can adjust the position of the second belt support member 42 and the third belt support member 44 based on the feel of the positioning roller 70 engaging in the groove 68a.

[0128] In addition, such as Figure 13 and Figure 17AAs shown, the locking pin 66 is exerted upward force by the spring 72. That is, the locking pin 66 is held outside the positioning hole 24a of the unit base member 24 of the retaining unit 20 by the spring 72. A locking pin drive rod 74 is provided on the third belt support member 42 to press the locking pin 66 toward the positioning hole 24a in order to push the locking pin 66 into the positioning hole 24a against the force of the spring 72. The locking pin drive rod 74 is supported on the third belt support member 44 in a manner that allows it to swing around a swing center line C3 extending along the length direction of the carrier belt (in this embodiment, the left-right direction of the belt cutting device 10) as a center. In addition, the locking pin drive rod 74 has a contact portion 74a that contacts the upper end of the locking pin 66. Moreover, the locking pin drive rod 74 has a cam follower 76. The driving of the locking pin 66 by the cam follower 76 and the locking pin drive rod 74 will be described later.

[0129] In the case of Figure 2B and Figure 9B When a carrier belt 300, as shown, with feed holes on both sides in the width direction, is placed in the belt holding unit 20, the user first adjusts the positions of the second belt support member 42 and the third belt support member 44. When the positions of the second belt support member 42 and the third belt support member 44 are adjusted, the belt pressing members 34 and 52 retract from above the plurality of first positioning pins 32 and second positioning pins 50 under the user's operation. In this state, the user places the carrier belt on the first belt support surface 28a of the first belt support member 28, the second belt support surface 42a of the second belt support member 42, and the third belt support surface 44a of the third belt support member 44. Simultaneously, the user moves the plurality of first positioning pins 32 and second positioning pins 50 into the feed holes of the carrier belt. After the carrier belt is placed and the positioning pins are moved into the feed holes, the belt pressing members 34 and 52 move upwards on the carrier belt under the user's operation. Thus, the carrier belt with feed holes on both sides in the width direction is placed in the belt holding unit 20.

[0130] In the case of Figure 2A and Figure 9AWhen a carrier belt, as shown in the first carrier belt 200, has a feed hole on only one side in the width direction, is placed in the belt holding unit 20, the user first inserts a plurality of first positioning pins 32 into the feed hole of the carrier belt, and then moves the belt pressing member 34 upward toward the first positioning pins 32. Next, the user moves the second belt support member 42 and the third belt support member 44 toward the carrier belt. As a result, the other end of the carrier belt in the width direction enters between the second belt support surface 42a and the belt pressing member 52, and enters between the third belt support surface 44a and the belt pressing member 56. Moreover, when the other end of the carrier belt in the width direction contacts the second positioning pin 50, the placement of the carrier belt with a feed hole on only one side in the width direction into the belt holding unit 20 is completed.

[0131] It should be noted that, in this embodiment, as Figure 16 and Figure 17A As shown, the second belt support member 42 and the third belt support member 44 have belt guide surfaces 42b and 44b extending obliquely downward from the leading edges (edges on the side of the first belt support member 28) of the second belt support surface 42a and the third belt support surface 44a. When the second belt support member 42 and the third belt support member 44 are moved toward a carrier belt that has a feed hole only on one side in the width direction, the ends of the carrier belt in the width direction are guided by the belt guide surfaces 42b and 44b, and easily enter between the second belt support surface 42a and the belt pressing member 52, and between the third belt support surface 44a and the belt pressing member 56.

[0132] The belt holding unit 20 described above can hold different types of carrier belts, such as those with different widths, different thicknesses, and those with feed holes located on one side or both sides of the width direction. Furthermore, different types of carrier belts can be placed at the belt holding unit 20 at the belt setting position P1 outside the housing 12, and after this placement, they can be conveyed to the belt cutting position P2 inside the housing 12.

[0133] Figure 18A This is a perspective view of the main body of the belt holder unit in its belt setting position while holding the first carrier belt. Additionally, Figure 18B This is a perspective view of the main body of the belt holding unit in the belt-cutting position while holding the first carrier belt. Furthermore, Figure 19A This is a perspective view of the main body of the belt holder unit in its belt setting position while holding the second carrier belt. Furthermore, Figure 19B This is a perspective view of the main body of the belt holding unit in the belt-cutting position while holding the second carrier belt. It should be noted that... Figure 18A and Figure 18B Corresponding to Figure 3A and Figure 3B .

[0134] As shown in Figure 18B and Figure 19B , when the tape holding unit 20 is located at the tape cutting position P2, the carrier tape is located above the tape cutting head 80 for cutting the carrier tape, as with the first carrier tape 200 and the second carrier tape 300. In addition, as shown in Figure 18A and Figure 19A , when the tape holding unit 20 is located at the tape setting position PI, the carrier tape is located at a position above which the tape cutting head 80 is separated in the width direction (in the case of the present embodiment, the front-rear direction of the tape cutting apparatus 10), as with the first carrier tape 200 and the second carrier tape 300. Specifically, the carrier tape is located at a position above which the tape cutting head 80 is separated in the front direction. Note that details of the tape cutting head 80 will be described later.

[0135] In addition, when the tape holding unit 20 moves from the tape setting position PI to the tape cutting position P2, the lock pin 66 provided to the third tape support member 44 changes from the state shown in Figure 17B to the state shown in Figure 17A .

[0136] Figure 20 is a side view showing a portion of the main body portion of the cam surface with which the cam follower of the lock pin drive lever comes into contact. Note that in Figure 20 , the illustration of the first shield member 62 is omitted.

[0137] As shown in Figure 20 and Figure 18A~Figure 19B , the main body portion 14 includes a top base member 82 disposed at an interval above the intermediate base member 22. The intermediate base member 22 and the top base member 82 are linked at their respective rear ends via a spacer member 84. That is, the top base member 82 is cantilevered supported to the spacer member 84.

[0138] When the tape holding unit 20 moves from the tape setting position PI to the tape cutting position P2, the carrier tape held by the tape holding unit 20 enters the space between the intermediate base member 22 and the top base member 82, as with the first carrier tape 200 and the second carrier tape 300 shown in Figure 18B and Figure 19B . As a result, the cam follower 76 of the lock pin drive lever 74 provided to the third tape support member 44 that supports the carrier tape also enters the space between the intermediate base member 22 and the top base member 82.

[0139] As shown in Figure 20 , a cam surface 82a with which the cam follower 76 comes into contact is provided to the top base member 82. The cam surface 82a is formed so as to be lower in the rear side portion than in the front side portion.

[0140] According to such a cam surface 82a, when the tape holding unit 20 moves from the tape setting position PI to the tape cutting position P2, the cam follower 76 moves downward while rolling on the cam surface 82a. By this, the lock pin driving lever 74 swings, and its contact portion 74a presses the lock pin 66 downward as shown in FIG. 8. By this, the lock pin 66 enters the positioning hole 24a of the unit base member 24, and the second tape support member 42 and the third tape support member 44 are locked so as not to move with respect to the unit base member 24. Figure 17A

[0141] On the other hand, when the tape holding unit 20 moves from the tape cutting position P2 to the tape setting position PI, the cam follower 76 separates from the cam surface 82a, and the lock pin 66 is retracted from the positioning hole 24a by the spring 72 as shown in FIG. 9. By this, at the tape setting position PI, the second tape support member 42 and the third tape support member 44 can move with respect to the unit base member 24. As a result, at the tape setting position PI, a carrier tape having a different width can be set to the tape holding unit 20. Figure 17B

[0142] Hereinafter, the tape cutting head 80 of the tape cutting apparatus 10 for cutting the carrier tape held by the tape holding unit 20 will be described.

[0143] Figure 21 Figure 22 is a perspective view and a side view showing the main body portion of the tape cutting head. In addition, Figure 23 is a perspective view of the tape cutting head. Furthermore, Figure 24 is an exploded perspective view of the tape cutting head. Furthermore, Figure 25 is a perspective view showing the tape cutting head and the tape receiving member. Note that in Figure 21 and Figure 22 , the illustration of a part of the constituent elements such as the tape holding unit 20 is omitted so that the tape cutting head 80 can be seen.

[0144] As shown in FIG. 10, the tape cutting head 80 holds a first cutting blade 90 and a second cutting blade 92 for cutting the carrier tape. Figure 23

[0145] The first cutting blade 90 has a blade edge 90a extending in the width direction of the carrier tape (in the case of the present embodiment, the front-rear direction of the tape cutting apparatus 10) while extending obliquely upward in the front direction. The first cutting blade 90 is a cutting blade for performing a first cutting process of cutting both the base tape and the cover tape in the carrier tape.

[0146] ​​​​The second cutting blade 92 has a cutting edge 92a extending along the width direction of the carrier tape (in this embodiment, the front-rear direction of the tape cutting device 10). The second cutting blade 92 is a cutting blade used to perform a second cutting process that cuts only the base tape.

[0147] The first cutting edge 90 and the second cutting edge 92 are held at the tape cutting head 80 such that their cutting edges 90a and 92a are separated by a predetermined distance D in the longitudinal direction of the carrier tape (in this embodiment, the left-right direction of the tape cutting device 10). Thus, as... Figure 2A and Figure 2B The carrier tape is cut such that the front end of the cover tape in the longitudinal direction is located at a predetermined distance D ahead of the front end of the base tape, as shown in the first carrier tape 200 and the second carrier tape 300.

[0148] The cutting head 80 is driven by a cutting blade drive device 94. In this embodiment, the cutting blade drive device 94 is a cylinder. The cutting head 80 is driven by the cutting blade drive device 94 in the thickness direction of the carrier tape (in this embodiment, the vertical direction of the tape cutting device 10).

[0149] With cutting head 80 Figure 21 and Figure 22 As shown, a through hole 22a is formed in the intermediate base member 22 in the main body 14. Furthermore, the cutting blade drive device 94 is mounted on the bottom base member 96, which is spaced apart from the intermediate base member 22 and located below it. It should be noted that... Figure 21 and Figure 22 The diagram shows the state where the tape cutting head 80 is in its lowest position. This position is the position where the tape cutting head 80 does not interfere with the tape holding unit 20 when the tape holding unit 20 moves from the tape setting position P1 to the tape cutting position P2 or vice versa; that is, the retracted position of the tape cutting head 80.

[0150] In order to cut the carrier tape positioned at the tape cutting position P2 by the tape holding unit 20, the tape cutting head 80 rises from the retracted position under the action of the cutting blade drive device 94. At this time, as Figure 6 and Figure 7 As shown, the tape cutting head 80 passes through the through hole 24b formed in the unit base member 24 of the tape holding unit 20. Thus, the tape cutting head 80 is able to cut the carrier tape held in the tape holding unit 20.

[0151] like Figure 25As shown, a belt receiving member 98, which receives the carrier belt pressed by the first cutting blade 90 and the second cutting blade 92, is mounted on the lower surface of the top base member 82 when the belt cutting head 80 rises to cut the carrier belt. The belt receiving member 98 is positioned opposite the belt cutting head 80 in the thickness direction of the carrier belt (in this embodiment, the vertical direction of the belt cutting device 10) and has a belt receiving surface 98a for receiving the carrier belt. It should be noted that a recess 98b is formed in the belt receiving surface 98a to allow the cutting edge 90a of the first cutting blade 90 to pass entirely through the belt receiving surface 98a. As a result, the cutting edge 90a of the first cutting blade 90 can completely cut both the base belt and the cover belt.

[0152] like Figure 23 As shown, the second cutting blade 92 is held in the tape cutting head 80 in a manner that allows it to swing around the swing center line C4 extending along the length direction of the carrier tape, the reasons for which will be explained later. In this embodiment, the second cutting blade 92 is held in the cutting blade holding member 100, which is supported in the tape cutting head 80 in a manner that allows it to swing around the swing center line C4.

[0153] The second cutting edge 92, as described above, does not cut the cover tape but only the base tape. Therefore, it is necessary to position the cutting edge 92a of the second cutting edge 92 relative to the tape-receiving surface 98a of the tape-receiving member 98 such that the gap between the cutting edge 92a of the second cutting edge 92 and the tape-receiving surface 98a of the tape-receiving member 98 is approximately equal to the thickness of the cover tape. Therefore, in this embodiment, as... Figure 21 and Figure 22 As shown, a stop member 102 that contacts the cutting blade retaining member 100 is provided on the top base member 82, which is provided with a receiving member 98. In this embodiment, the stop member 102 is a screw that engages with a threaded hole formed in the top base member 82, and has a contact surface 102a at its front end that contacts the cutting blade retaining member 100. Since the stop member 102 is a screw, the position of the contact surface 102a in the thickness direction of the carrier tape (in this embodiment, the vertical direction of the tape cutting device 10) can be adjusted.

[0154] It should be noted that, in this embodiment, the portion of the cutting edge holding member 100 that contacts the contact surface 102a of the stop member 102 can be adjusted in position relative to the cutting edge 92a of the second cutting edge 92. In this embodiment, a stop receiving member 104 is mounted on the cutting edge holding member 100 to receive the stop member 102 in a manner that allows it to move in the thickness direction of the carrier tape (in this embodiment, the vertical direction of the tape cutting device 10). The stop receiving member 104 has a contact surface 104a that contacts the contact surface 102a of the stop member 102. The stop receiving member 104 is configured to move relative to the cutting edge holding member 100, thus allowing adjustment of the relative position of the contact surface 104a with respect to the cutting edge 92a of the second cutting edge 92.

[0155] Therefore, in this embodiment, the position of the contact surface 102a of the stop member 102 and / or the position of the contact surface 104a of the stop receiving member 104 can be adjusted according to the thickness of the cover tape in the cut carrier tape. As a result, it is possible to cut only the base tape in various carrier tapes without cutting the cover tape.

[0156] From this point onward, we will explain why the second cutting edge 92 is positioned on the cutting head 80 in a swingable manner.

[0157] like Figure 22 As shown, the second cutting blade 92 in the tape cutting device 10 of this embodiment cuts both the base tape 202 of the narrow first carrier tape 200 and the base tape 302 of the wide second carrier tape 300, but does not cut the cover tapes 204 and 304. In particular, in order to completely cut the base tape 302 entirely in the width direction without cutting the cover tape 304 in the wide carrier tape 300, it is necessary to strictly manage the inclination of the cutting edge of the second cutting blade 92 (the inclination when viewed in the length direction of the carrier tape). However, this is difficult in practice.

[0158] Furthermore, in this embodiment, the top base member 82, which is provided with the belt support member 98, is cantilevered. Therefore, when the second cutting edge 92 contacts the carrier belt, the top base member 82 flexes and deforms via the carrier belt and the belt support member 98 in a manner that avoids the belt cutting head 80. This will be explained in detail below.

[0159] Figure 26 This is a conceptual diagram showing the top base member flexing and deforming as the second cutting edge contacts the base of the carrier belt.

[0160] like Figure 26As shown, when the tape cutting head 80 is moved by the action of the cutting blade driving device 94 and the blade edge 92a of the second cutting blade 92 comes into contact with the base tape 402 in the tape 400, the top base member 82 is pressed by the tape cutting head 80 via the base tape 402, the cover tape 404, and the tape receiving member 98. As a result, the top base member 82 is deformed in a manner to avoid the tape cutting head 80.

[0161] At this time, in the case where the second cutting blade 92 is not provided to the tape cutting head 80 in a manner to be able to swing, the blade edge 92a of the second cutting blade 92 can not be able to cut the base tape 402 in the entire width direction.

[0162] Figure 27A is a conceptual diagram of a comparative example in which the second cutting blade is not provided to the tape cutting head in a manner to be able to swing. Figure 27B is a conceptual diagram of an embodiment in which the second cutting blade is provided to the tape cutting head in a manner to be able to swing.

[0163] As shown in the comparative example, when the top base member 82 is pressed by the tape cutting head 80 via the base tape 402, the cover tape 404, and the tape receiving member 98 and is thereby deformed, the tape 400 received by the tape receiving member 98 is inclined. In the comparative example in which the second cutting blade 92 is not provided to the tape cutting head 80 in a manner to be able to swing, the blade edge 92a of the second cutting blade 92 cannot be inclined in correspondence with the inclination of the tape 400. As a result, the blade edge 92a of the second cutting blade 92 cannot pass through the entire base tape 402, and a cut remaining is generated in the base tape 402. Depending on the situation, a part of the cover tape 404 is cut by the second cutting blade 92. Figure 27A In the embodiment shown in

[0164] , also as in the comparative example, when the top base member 82 is pressed by the tape cutting head 80 via the base tape 402, the cover tape 404, and the tape receiving member 98 and is thereby deformed, the tape 400 received by the tape receiving member 98 is inclined. However, the second cutting blade 92 is provided to the tape cutting head 80 in a manner to be able to swing, and therefore the blade edge 92a can be inclined in correspondence with the inclination of the tape 400. As a result, the blade edge 92a of the second cutting blade 92 can pass through the entire base tape 402, and the base tape 402 can be completely cut in the entire width. Figure 27B

[0165] ​It should be noted that, preferably, when cutting a carrier belt with a large width, such as the second carrier belt 300, the portion of the cutting blade holding member 100 that contacts the stop member 102 (in this embodiment, the stop receiving member 104) is respectively provided on both sides of the carrier belt in the width direction (in this embodiment, the front-rear direction of the belt cutting device 10) relative to the second cutting blade 92. If the portion contacting the stop member 102 is only on one side, the cutting blade holding member 100 may rotate around the contact point with the stop member 102. As a result, the second cutting blade 92 may not be able to cut the base belt entirely in the width direction.

[0166] Moreover, in this embodiment, such as Figure 1 and Figure 5 As shown, the cutting device 10 includes second shielding members 110 and 112 that seal the opening 12a of the housing 12. To explain the function of the second shielding members 110 and 112, a comparative example will be used to explain the problems that occur when the second shielding members 110 and 112 are not present.

[0167] Figure 28 This is a side view of a comparative example of a tape cutting device with the second carrier tape passing through the opening in the housing. Additionally, Figure 29 This is a side view of a comparative example of a belt cutting device after the second carrier belt has been removed from the belt cutting device.

[0168] like Figure 28 As shown, when the second carrier tape 300 is in the tape cutting position P2, the second carrier tape 300 passes through the opening 12a of the housing 12 (i.e., housing cover 16). The opening 12a of the housing 12 is sized to accommodate the maximum width and thickness of the carrier tape that the tape cutting device 10 can cut. In this embodiment, the opening 12a is the size through which the second carrier tape 300 can pass.

[0169] like Figure 29 As shown, when the second carrier tape 300 after cutting is removed from the cutting device 10, a space S1 communicating with the opening 12a appears within the housing 12. This space S1 is the space between the unit base member 24 of the holding unit 20 and the top base member 82 of the main body 14. As a result, a user's finger can enter this space S1 through the opening 12a. Furthermore, a first cutting blade 90 and a second cutting blade 92 are located below the space S1. Therefore, there is a possibility that the user's finger entering the space S1 may come into contact with the first cutting blade 90 and the second cutting blade 92.

[0170] Thus, the reason why the user's finger comes into contact with the first cutting blade 90 and the second cutting blade 92 arranged in the housing 12 is because the tape cutting apparatus 10 is configured to be able to cut a plurality of tapes having different widths and thicknesses. That is, in the case of cutting only a tape having a small width and thickness like the first tape 200, the opening 12a of the housing 12 through which such a tape passes is sized such that the user's finger cannot pass therethrough. On the other hand, when a tape having a large width and thickness like the second tape 300 can be cut, the opening 12a of the housing 12 through which such a tape passes is sized such that the user's finger can pass therethrough.

[0171] In order to block the opening 12a of the housing 12 from the user's finger, as shown in Figure 5 The second shielding members 110, 112 are provided to the tape cutting apparatus 10.

[0172] In the case of the present embodiment, as shown in Figure 5 The second shielding members 110, 112 are installed to the intermediate base member 22 of the main body portion 14 in a manner that they are movable in the up-and-down direction. In addition, the second shielding members 110, 112 are urged in the upward direction by springs 114. Note that the second shielding members 110, 112 are identical in operation and function except that they are left-right symmetrical in shape, and thus only the second shielding member 110 will be described from here on.

[0173] Figure 30 is a side view of the tape cutting apparatus in a state in which the opening of the housing is blocked by the second shielding member. In addition, Figure 31 is a side view of the tape cutting apparatus in a state in which the second tape passes through the opening of the housing.

[0174] As shown in Figure 30 When the second shielding member 110 is raised to the maximum and opposes the opening 12a of the housing 12 in the length direction of the tape (in the case of the present embodiment, the left-and-right direction of the tape cutting apparatus 10), most of the opening 12a is blocked. The second shielding member 110 is raised to a distance L between the upper end thereof and the upper edge of the opening 12a, which is sized such that the user's finger cannot pass therethrough.

[0175] As shown in Figure 31As shown, in the case where the second tape 300 having a large thickness passes through the opening 12a of the housing 12, that is, in the case where the second tape 300 is disposed at the tape cutting position P2 just before and just after being cut by the tape cutting head 80, the second shield member 110 comes into contact with the second tape 300 and stops. When the cut second tape 300 is taken out of the tape cutting apparatus 10, the second shield member 110 is urged upward by the spring 114. Thus, the spring 114 urges the second shield member 110 in the upward direction with a force that does not crush the tape in the thickness direction by the second shield member 110. Further, by the second tape 300 coming into contact with the second shield member 110, the user's fingers are prevented from entering the space between the second tape 300 and the unit base member 24 of the tape holding unit 20.

[0176] Note that, in the case of a tape having a small thickness like the first tape 200, that is, a tape having a thickness smaller than the distance L, the tape does not come into contact with the second shield member 110.

[0177] The second shield member 110 does not always block the opening 12a of the housing 12. When the tape holding unit 20 is present at a position other than the tape cutting position P2, the second shield member 110 does not oppose the opening 12a.

[0178] The reason is as follows. Since the tape holding unit 20 moves from the tape setting position PI to the tape cutting position P2, the held tape moves from the outside of the opening 12a to the inside of the opening 12a. At this time, when the second shield member 110 opposes the opening 12a, the tape cannot enter the opening 12a. Therefore, when the tape is present outside the opening 12, the second shield member 110 retreats downward from the position opposing the opening 12a.

[0179] Therefore, the movement of the second shield member 110 is linked to the movement of the tape holding unit 20.

[0180] Figure 32 and Figure 33 are a perspective view and a side view showing the position of the second shield member when the tape holding unit is present at the tape setting position. Further, Figure 34 and Figure 35 are a perspective view and a side view showing the position of the second shield member when the tape holding unit is present at the tape cutting position.

[0181] As Figure 32~Figure 35As shown, in the case of the present embodiment, the second shielding member 110 is raised toward the position opposite the opening 12a of the housing 12 in conjunction with the movement of the tape holding unit 20 from the tape setting position Pl to the tape cutting position P2. In addition, the second shielding member 110 is lowered from the position opposite the opening 12a in conjunction with the movement of the tape holding unit 20 from the tape cutting position P2 to the tape setting position Pl. In order to achieve such a linkage, in the case of the present embodiment, a drive linkage mechanism that links the tape holding unit 20 and the second shielding member 110 is provided to the tape cutting apparatus 10.

[0182] Specifically, in the case of the present embodiment, the drive linkage mechanism is composed of a cam groove 110a provided to the second shielding member 110, and a cam follower 116 provided to the tape holding unit 20 and disposed within the cam groove 110a. As shown, Figure 33 and Figure 35 As shown, the cam groove 110a extends at a constant width from the front end thereof toward the rear. Also, near the rear end of the cam groove 110a, the width of the cam groove 110a gradually expands. That is, the lower side surface 110b of the cam groove 110a extends in a straight line in the front-rear direction from the front end to a relay point 110c, and is inclined downward from the relay point 110c to the rear end. Therefore, according to such a cam groove 110a, when the tape holding unit 20 is located at the tape setting position Pl, the second shielding member 110 is restricted from being raised toward the position opposite the opening 12a. In addition, when the tape holding unit 20 is located at the tape cutting position P2, the second shielding member 110 is allowed to be raised toward the position opposite the opening 12a.

[0183] The reason for making the second shielding member 110 link with the tape holding unit 20 using such a drive linkage mechanism composed of the cam groove 110a and the cam follower 116, and the spring 114 that exerts a force in the upward direction on the second shielding member 110, is because the thicknesses of the various kinds of carrier tapes disposed to the opening 12a are different. It is possible to raise the second shielding member 110 using only the cam groove 110a and the cam follower 116, but in that case, the second shielding member 110 can possibly crush a carrier tape having a large thickness in the thickness direction thereof. Or it can possibly create a gap of a size that a user's finger can enter between a carrier tape having a small thickness and the second shielding member 110. Considering the differences in the thicknesses of such various kinds of carrier tapes, instead of raising the second shielding member 110 using only the cam groove 110a and the cam follower 116, the spring 114 is used.

[0184] When the tape holding unit 20 moves from the tape setting position Pl toward the tape cutting position P2, the cam follower 116 rolls on the lower side surface 110b of the cam groove 110a and moves in the rearward direction. Before the cam follower 116 reaches the relay point 110c, a portion of the carrier tape (strictly speaking, a carrier tape having a thickness smaller than the thickness of the second shielding member 110) disposed to the opening 12a is crushed in the thickness direction thereof by the second shielding member 110. In addition, a gap of a size that a user's finger can enter is created between the carrier tape and the second shielding member 110. Figure 30A portion of the carrier belt (shown as a distance L) enters the opening 12a. When the cam follower 116 passes the relay point 110c, the second shielding member 110 begins to rise toward a position opposite to the opening 12a. Through this drive linkage mechanism, the second shielding member 110 does not obstruct the entry of the carrier belt into the opening 12a, and the second shielding member 110 can be linked with the belt holding unit 20.

[0185] It should be noted that, in this embodiment, the cam groove 110a is provided on the second shielding member 110, and the cam follower 116 is provided on the belt holding unit 20. Alternatively, the cam groove may be provided on the belt holding unit 20, and the cam follower may be provided on the second shielding member 110.

[0186] like Figure 35 As shown, when the belt holding unit 20 is in the belt cut position P2, the second shielding member 110 may be forcibly lowered if it is pressed downward against the force of the spring 114. In order to suppress such forced lowering of the second shielding member 110, a one-way locking member 118 is provided in the belt holding unit 20 to engage with the second shielding member 110 and limit the lowering.

[0187] Specifically, the one-way locking member 118 is a member having ratchet teeth 118a. A leaf spring 120 that contacts the ratchet teeth 118a is disposed on the second shielding member 110. The leaf spring 120 extends obliquely downward from the second shielding member 110 toward the ratchet teeth 118a.

[0188] In addition, such as Figure 32 and Figure 33 As shown, when the belt holding unit 20 is in the belt setting position P1, the one-way locking member 118 does not contact the second shielding member 110. On the other hand, as Figure 34 and Figure 35 As shown, when the belt holding unit 20 is in the belt cut-off position P2, the one-way locking member 118 contacts the second shielding member 110 via the leaf spring 120.

[0189] Based on such a one-way locking member 118 and a leaf spring 120 of a second shielding member 110, in such a way... Figure 34 and Figure 35 When they are in contact as shown (when the belt holding unit 20 is in the belt cutting position P2), the descent of the second shielding member 110 is restricted. On the other hand, the rise of the second shielding member 110 is permitted. The reason for this is that after the cut carrier belt is removed from the belt cutting device 10, the second shielding member 110 needs to rise to block the opening 12a of the housing 12.

[0190] It should be noted that, as described above, when the belt holding unit 20 is in the belt setting position P1, such asFigure 33 As shown, the second shielding member 110 is not located opposite the opening 12a of the housing 12. Instead, the first shielding member 60 provided on the belt holding unit 20 is located opposite the opening 12a. Thus, when the belt holding unit 20 is in the belt setting position P1, the first shielding member 60 covers the opening 12a. Furthermore, as... Figure 35 As shown, when the belt holding unit 20 is in the belt cutting position P2, the first shielding member 60 is present in a position not opposite to the opening 12a.

[0191] In this embodiment, as described above and as follows Figure 23 As shown, the drive device 94 that drives the cutting blade of the belt cutting head 80 is a cylinder that operates using air pressure. The belt cutting device 10 of this embodiment operates without the use of electricity.

[0192] Figure 36 This is an air circuit diagram for activating the cutting device involved in this embodiment.

[0193] like Figure 36 As shown, the air circuit that operates the cutting device 10 according to this embodiment includes a compressed air source 130 such as a compressor, a manual start valve 132 for starting the operation of the cutting device 10 manually by the user, a mechanical valve 134 that operates under external force, a pneumatic valve 136 that operates under the supply of pilot air, a cutting blade drive device 94 (cylinder), and a timing reporting cylinder 138 for reporting the timing of the removal of the carrier tape to the user. It should be noted that... Figure 36 In the diagram, the manual start valve 132, the mechanical valve 134, and the pneumatic valve 136 are shown in the closed state.

[0194] Manual start valve 132 is a 5-port valve, and as Figure 1 It is disposed on the front surface of the housing 12 with the shut-off device 10 as shown. The manual start valve 132 is opened / closed by user operation.

[0195] Mechanical valve 134 is a 3-port valve, and as Figure 20 As shown, it is disposed on the intermediate base member 22. The mechanical valve 134 changes from the closed state to the open state when it contacts the mechanical valve actuating rod 140 disposed on the belt holding unit 20. The mechanical valve actuating rod 140 contacts the mechanical valve 134 when the belt holding unit 20 is in the belt cut-off position P2.

[0196] Pneumatic valve 136 is a 3-port valve, and as Figure 4 It is installed on the bottom base component 96 as shown. The pneumatic valve 136 changes from the closed state to the open state when the pilot pressure reaches the specified pressure.

[0197] Timing report uses cylinder 138, such asFigure 4 It is positioned near the manual start valve 132 as shown. Additionally, its rod 138a is as follows... Figure 1 It protrudes from the front surface of the housing 12 as shown.

[0198] like Figure 36 As shown, when the belt cutting device 10 is in the closed state before its operation begins, air from the compressed air source 130 is supplied to the rod-side port of the cutting blade drive device 94 (cylinder), and the rod 94a is in a retracted state. That is, the belt cutting head 80 is retracted to a position that does not interfere with the movement between the belt setting position P1 and the belt cutting position P2 of the belt holding unit 20.

[0199] When the user sets the manual start valve 132 to the open state, air from the compressed air source 130 is supplied to the mechanical valve 134. At the same time, the rod-side port of the cutting blade drive device 94 (cylinder) is connected to the atmosphere.

[0200] If the mechanical valve 134 is open (with the belt holding unit 20 in the belt-cutting position P2), the air supplied from the manual start valve 132 passes through the mechanical valve 134 and the closed pneumatic valve 136, supplying the head-side ports of the cutting blade drive device 94 (cylinder) and the timing reporting cylinder 138. As a result, the belt cutting head 80 moves toward the belt holder 20, which is held in the belt-cutting position P2. Simultaneously, the rod 138a of the timing reporting cylinder 138 advances.

[0201] Furthermore, the air following the opening of the mechanical valve 134 is supplied to the pneumatic valve 136 as pilot air via the speed controller 142.

[0202] The forward movement of the lever 94a of the cutting blade drive device 94 is as follows: Figure 22 As shown, the tape cutter 80 stops upon contact between the stop receiving member 104 and the stop member 102. That is, when the cutting of the carrier tape by the second cutting blade 92 of the tape cutter 80 is completed, the tape cutter 80 stops at the position where the cutting is completed. Approximately simultaneously, Figure 1 The timing report shown is achieved by using the rod 138a of cylinder 138 to advance to its maximum extent (to protrude to its maximum extent from housing 12).

[0203] The pilot pressure reaches a prescribed pressure after the tape cutting head 80 waits for a prescribed time (for example, 2 to 3 seconds) at the cut completion position, and the pneumatic valve 136 becomes the open state from the closed state. The flow rate of the pilot air is adjusted by the speed controller 142 in a manner that the pilot pressure reaches the prescribed pressure after the tape cutting head 80 waits for the prescribed time at the cut completion position. Note that the reason for causing the tape cutting head 80 to wait for the prescribed time at the cut completion position is to reliably cut the base tape of various kinds of carrier tapes having different shearing resistances and thicknesses by the second cutting blade 92 by spending time.

[0204] When the pneumatic valve 136 becomes the open state, the head side ports of the cutting blade driving device 94 (cylinder) and the timing reporting cylinder 138 are each connected to the atmosphere. Thus, the rod 94a of the cutting blade driving device 94 is retracted under the weight of the tape cutting head 80.

[0205] When the tape cutting head 80 moves to the cut blade retreat position at which the blade edge 92a of the second cutting blade 92 is away from the cut base tape, the rod 138a of the timing reporting cylinder 138 is retracted. The speed controller 142 disposed between the pneumatic valve 136 and the timing reporting cylinder 138 adjusts the flow rate in a manner that the rod 138a is retracted at the timing at which the tape cutting head 80 reaches the cut blade retreat position. The user can confirm the retraction of the rod 138a and take out the cut carrier tape from the tape cutting apparatus 10 in the length direction (in the case of the present embodiment, the left-right direction of the tape cutting apparatus 10) without moving the tape holding unit 20 to the tape setting position PI. That is, after the cutting is completed, there is no unnecessary waiting time (waiting is not necessary), and the carrier tape can be immediately taken out.

[0206] The tape cutting apparatus 10 according to such a structure is operated by the user as follows.

[0207] First, the user adjusts the position of the contact surface 102a of the stop member 102 and / or the position of the contact surface 104a of the stop receiving member 104 according to the thickness of the cover tape of the carrier tape to be cut. Figure 22 This adjustment is performed when the kind of the carrier tape to be cut by the tape cutting apparatus 10 is changed.

[0208] Next, the user pulls the tape holding unit 20 to the tape setting position PI in the forward direction. With respect to the tape holding unit 20 on the tape setting position PI, the user sets the carrier tape as described above. Thus, the tape holding unit 20 holds the carrier tape.

[0209] Next, the user presses the tape holding unit 20 holding the carrier tape toward the rearward direction to move it to the tape cutting position P2.

[0210] Further, the user operates the manual start valve 132 to be set to the open state. By confirming the advance of the rod 138a of the timing reporting cylinder 138, the user can know the start of the cutting of the tape.

[0211] After a lapse of a certain time from the operation of the manual start valve 132 to be set to the open state, the rod 138a of the timing reporting cylinder 138 is retracted. When the retraction of the rod 138a is confirmed, the user lifts the pin driving lever 38 to pull out the positioning pin 32 from the feeding hole of the tape (moves the positioning pin 32 toward the first engagement release position (first engagement release position) and in the downward direction) and pulls the tape in the longitudinal direction of the tape, and takes out the tape of which the cutting is completed from the tape cutting apparatus 10. Then, the user operates the manual start valve 132 to be set to the closed state. Figure 11B
