Description

  The present invention relates to a tape cutting device for cutting a tape in which an electronic component is accommodated.

  FIG. 35A shows a top view of the tape feeder. FIG. 35B shows a side view of the tape feeder. The tape feeder 100 is attached to an electronic component mounting machine (not shown). The tape feeder 100 includes a feeder body 101, a tape 102, a reel 103, and a sprocket 104.

  The reel 103 is attached to the feeder main body 101. The tape 102 is wound around the reel 103. The tape 102 includes a carrier tape 102a and a pair of front and back cover tapes 102b. The carrier tape 102a has a large number of feed holes 102aa and a large number of component accommodating portions 102ab. A large number of feed holes 102aa are arranged in the longitudinal direction at predetermined pitches. Many component accommodating parts 102ab are arranged in the longitudinal direction for every predetermined pitch. The pair of front and back cover tapes 102b are affixed to the front and back surfaces of the carrier tape 102a. The pair of front and back cover tapes 102b seal the front and back openings of a large number of component housing portions 102ab. An electronic component (not shown) is enclosed in each of the large number of component accommodating portions 102ab.

  The sprocket 104 is attached to the feeder main body 101. On the outer peripheral surface of the sprocket 104, feed dogs 104a are arranged at predetermined pitches. The feed dog 104a can be engaged with and disengaged from the feed hole 102aa of the tape 102. The sprocket 104 is rotationally driven by a motor (not shown). As the sprocket 104 rotates, the tape 102 is pulled out from the reel 103. A component supply position 108 is set at the tip of the feeder main body 101. The electronic component of the tape 102 is taken out from the component supply position 108 by a suction nozzle (not shown) of the electronic component mounting machine. The extracted electronic component is mounted on the substrate.

  The sprocket 104 causes a large number of component accommodating portions 102ab to reach the component supply position 108 in order and stepwise. The unit rotation amount of the sprocket 104 (that is, the unit feed amount of the tape 102) corresponds to the pitch between the large number of component accommodating portions 102ab.

  As a large number of electronic components of the tape 102 are mounted on the substrate, the tape 102 is gradually consumed. When the remaining amount of the tape 102 becomes equal to or less than the predetermined amount, an operation of joining a new tape to the tape 102 being used, that is, a splicing operation is executed.

  FIG. 36 (a) shows a schematic diagram of the first stage of the splicing work of the tape. FIG. 36B shows a schematic diagram of the second stage of the splicing work of the tape. FIG. 36 (c) shows a schematic diagram of the third stage of the tape splicing operation.

  In the splicing operation, first, as shown in FIG. 36A, the operator uses a scissors 106 to move the vicinity of the tip 105c of the new tape 105 to a predetermined cutting position 105d (ideally, the short side of the tape 102). Cutting is performed at a predetermined position extending in the direction (for example, a straight line position passing through the center of the feed hole 105aa). Similarly, the operator uses the scissors 106 to close the vicinity of the rear end 102c of the tape 102 in use to a predetermined cutting position 102d (ideally, a predetermined position (for example, a feed hole) extending in the short direction of the tape 102. A straight line passing through the center of 102aa))).

  Next, as shown in FIG. 36B, the operator aligns the cutting position 105d of the new tape 105 with the cutting position 102d of the tape 102 in use. Then, as shown in FIG. 36C, the operator connects the new tape 105 and the tape 102 in use by the connecting tape 107. In this way, the splicing operation is executed.

JP-A-4-243757 JP-A-6-336362

  However, during the splicing operation, as shown in FIG. 36A, the cutting position 105d of the new tape 105 may be displaced in the longitudinal direction as the cutting position 105da. Similarly, the cutting position 102d of the tape 102 in use may be displaced in the longitudinal direction as the cutting position 102da.

  In such a case, as shown in FIG. 36C, the pitch of the large number of feed holes 102aa and the pitch of the large number of feed holes 105aa deviate from each other at the tape connection position (cutting positions 102d and 105d). End up. For this reason, the pitch of many component accommodating parts 105ab and the pitch of many component accommodating parts 102ab will shift | deviate from a tape connection position. Therefore, as shown in FIGS. 35 (a) and 35 (b), when the spliced tape 102 is pulled out by the sprocket 104, the component accommodating portion 102ab with respect to the component supply position 108 at the tape connection position. (In other words, electronic components) will shift. Therefore, it becomes difficult for the suction nozzle of the electronic component mounting machine to take out the electronic component from the component supply position 108.

  Further, at the time of splicing work, as shown in FIG. 36A, the cutting position 105d of the new tape 105 may be inclined with respect to the short-side direction as the cutting position 105db. Similarly, the cutting position 102d of the tape 102 in use may be inclined with respect to the short-side direction like the cutting position 102db.

  In such a case, the connecting operation itself between the new tape 105 and the tape 102 in use becomes difficult. Further, there is a possibility that the new tape 105 and the tape 102 in use are connected in a “polyline shape”.

  Thus, in the splicing operation, it is extremely important to cut the tapes 102 and 105 at the ideal cutting positions 102d and 105d. That is, it is extremely important to improve the cutting accuracy of the tapes 102 and 105.

  As an apparatus for cutting a tape, Patent Document 1 discloses an automatic tape connecting apparatus. Patent Document 2 discloses a tape connecting jig. When the automatic connection device of Patent Document 1 and the tape connection jig of Patent Document 2 are used, the cutting accuracy of the tape can be improved as compared with the case where the scissors 106 are used.

  However, when the automatic connection device of Patent Document 1 and the tape connection jig of Patent Document 2 are used, the tape may move in the front-back direction when the tape is cut. That is, in the case of the automatic connection device of Patent Document 1, the tape is not fixed from the front and back directions when the tape is cut. For this reason, there exists a possibility that a tape may move to the front and back direction at the time of tape cutting | disconnection by the shearing force of a cutter, etc. Further, in the case of the tape connecting jig of Patent Document 2, as shown in FIG. 4 of the same document, the safety cover covers the tape from the front side when the tape is cut. However, this document does not describe “the safety cover restricts the movement of the tape in the front and back direction”. For this reason, there exists a possibility that a tape may move to the front and back direction at the time of tape cutting | disconnection by the pressing force of a cutter, etc.

  Further, as shown in FIG. 35B, the tape 102 is wound around the reel 103. For this reason, the tape 102 pulled out from the reel 103 has a “roller”. Due to the “winding wrinkle”, the tape 102 is more easily moved in the front and back direction when the tape 102 is cut. In this regard, in the case of the tape connecting jig of Patent Document 2, as shown in FIG. 1 of the same document, the safety cover can swing with a predetermined swing radius. For this reason, the safety cover approaches the tape while drawing an arc-shaped track from an oblique direction with respect to the vertical line (vertical line). Therefore, the tape can easily escape to the outside in the radial direction of the swing radius of the safety cover. Therefore, the tape cutting accuracy is reduced.

  Moreover, in the case of the jig for tape connection of patent document 2, as shown in FIG. 4 of the same document, the blade edge | tip receiving plate is arrange | positioned directly under a cutter. For this reason, in the final stage at the time of cutting the tape, the tape is crushed between the cutter and the blade receiving plate. Therefore, irregularities are likely to occur on the cut surface of the tape. That is, the tape cutting accuracy is lowered.

  The tape cutting device of the present invention has been completed in view of the above problems. An object of the present invention is to provide a tape cutting device in which the tape is difficult to move in the front and back direction when the tape is cut.

  (1) In order to solve the above-mentioned problems, the tape cutting device of the present invention regulates the movement of the tape in the front and back direction when the tape is cut, and the cutter that cuts the tape for electronic components at a predetermined cutting position. And a front / back direction restricting portion.

  The tape cutting device of the present invention includes a front and back direction restricting portion. For this reason, when the tape is cut, the tape hardly moves in the front-back direction. Therefore, the tape cutting accuracy can be improved.

  (1-1) Preferably, in the configuration of the above (1), it is better to have a configuration including a cutter insertion hole into which the cutter after cutting the tape enters. According to this configuration, the entire cut position of the tape is cut by shearing. For this reason, there is little possibility that the tape will be crushed like the tape connecting jig of Patent Document 2. Therefore, the tape cutting accuracy can be improved.

  (2) Preferably, in the configuration of (1) above, a base having a guide groove for guiding the tape on the surface thereof is provided, and the front and back direction restricting portion presses the tape from the front side when cutting the tape. Therefore, it is better to have a structure that is a pressing member that sandwiches the tape from the front and back directions with the groove bottom surface of the guide groove.

  According to this configuration, the surface of the tape is pressed by the pressing member when the tape is cut. In addition, the back surface of the tape is pressed by the groove bottom surface of the guide groove. For this reason, the tape is difficult to move in the front and back direction.

  (2-1) Preferably, in the configuration of (2) above, the pressing member may be in contact with the tape from a direction perpendicular to the surface of the tape. According to this configuration, the load in the short direction of the tape hardly acts on the tape from the pressing member. For this reason, unlike the tape connection jig of Patent Document 2, there is little possibility that the tape will escape in the short direction. Therefore, the tape cutting accuracy can be improved.

  (3) Preferably, in the configuration of the above (1) or (2), it is better to have a configuration in which a short direction restricting portion that restricts the movement of the tape in the short direction when the tape is cut is provided. According to this configuration, when the tape is cut, the tape hardly moves not only in the front and back direction but also in the short direction. Therefore, the tape cutting accuracy can be improved.

  (4) Preferably, in the configuration of the above (3), the tape has a plurality of feed holes arranged at predetermined pitches along the longitudinal direction, and the short-side direction restricting portion includes the tape. A sprocket having a plurality of feed teeth that engage with the feed holes of the tape when cutting, and positioning that engages with the feed holes other than the feed holes with which the feed teeth engage when cutting the tape And a pin.

  According to this configuration, the feed dog of the sprocket is engaged with an arbitrary feed hole when the tape is cut. In addition, positioning pins are engaged with other feed holes. For this reason, at the time of tape cutting, the tape can be fixed at at least two places in the longitudinal direction of the tape. For this reason, when the tape is cut, the tape hardly moves in the short direction.

  (5) Preferably, in any one of the constitutions (1) to (4), the operation unit operated by the operator, and the tape is fed downstream by a predetermined feed amount in conjunction with the operation unit. A distance between the reference position set upstream with respect to the cutting position and the cutting position is set to an integral multiple of the feed amount. Good.

  According to this configuration, the operator can manually move the operation unit to feed the tape and cut the tape. For this reason, even when there is no supply of electricity, the tape can be cut with high accuracy.

  Further, according to this configuration, the distance between the reference position and the cutting position is set to an integral multiple of the feed amount. For this reason, by aligning the position to be cut (cutting target position) of the tape with the reference position and moving the operation unit, the position to be cut of the tape can be easily and accurately aligned with the cutting position.

  (5-1) Preferably, in the configuration of (5) above, the cutting position is preferably arranged at a position where it cannot be visually recognized from the outside. According to this configuration, the cut position of the tape can be aligned with the cutting position easily and with high accuracy even though the cutting position cannot be visually recognized.

  (6) Preferably, in the configuration of (5), the tape has a plurality of feed holes arranged at a predetermined pitch along the longitudinal direction, and the tape feed portion is interlocked with the operation portion. And a ratchet having a plurality of regulating teeth, and a pawl member that can be engaged with and disengaged from the regulating teeth and regulates the rotation direction of the gears in a direction to feed the tape from the upstream side to the downstream side. And a sprocket having a plurality of feed teeth that rotate in conjunction with the gear and engage with the feed holes of the tape, and the feed amount is an integral multiple of the pitch of the plurality of regulation teeth It is better to have a configuration set to.

  The tape feeding part has a ratchet part and a sprocket. The ratchet part has a gear and a pawl member. The gear has a plurality of restriction teeth. The feed amount is set to an integral multiple of the pitch of the plurality of regulating teeth. According to this configuration, it is possible to reliably align the cut position of the tape with the cutting position.

  Further, the pawl member allows rotation in the forward direction of the gear (the direction in which the tape is fed from the upstream side to the downstream side). On the other hand, the pawl member prohibits rotation in the reverse direction of the gear (the direction in which the tape is fed from the downstream side to the upstream side). For this reason, there is little possibility that the tape is fed in the reverse direction.

  (6-1) Preferably, in the configuration of (6) above, the distance between the insertion position disposed upstream of the reference position and the reference position is an integral multiple of the feed amount. The tape is sent by the operator from the insertion position to the reference position, and the tape feeding unit confirms that the tape has been fed by the feeding amount to the operator. It is better to adopt a configuration in which the pawl can be transmitted by a change in the reaction force received by the operator when getting over the restriction tooth of the gear.

  According to this configuration, the insertion position, the reference position, and the cutting position are arranged from the upstream side to the downstream side. From the insertion position to the reference position, the tape is fed by the operator's own power. Here, the distance between the insertion position and the reference position is set to an integral multiple of the feed amount. Further, the tape feeding unit can transmit to the operator that the tape has been fed by the unit feeding amount by a change in the reaction force when the pawl member gets over the regulating tooth. For this reason, the operator can recognize that the tape has reached the reference position based on the number of times the reaction force is felt.

  For example, when the distance between the insertion position and the reference position is set to three times the feed amount, the operator recognizes that the tape has reached the reference position by feeling the reaction force change three times. can do.

  (7) Preferably, in any one of the constitutions (1) to (6), a base having a guide groove for guiding the tape on the surface thereof, and a storage portion disposed on the front side of the base for storing the cutter A cutter unit having a stopper unit capable of regulating the movement of the cutter, a closed mode in which the cutter unit is closed with respect to the base, and an open mode in which the cutter unit is opened with respect to the base; In the closed mode, the stopper portion allows the cutter to move, so that the cutter can protrude from the receiving portion. In the open mode, the stopper portion is the cutter. It is better to have a configuration in which the cutter cannot be protruded from the accommodating portion by restricting the movement.

  The closed mode is used when cutting the tape. On the other hand, the open mode is used when removing the cut tape, when exchanging the cutter, or during maintenance. According to this configuration, in the closed mode, the cutter can protrude from the accommodating portion. For this reason, the tape can be cut. On the other hand, in the open mode, the cutter cannot protrude from the accommodating portion. For this reason, safety is high.

  According to the present invention, it is possible to provide a tape cutting device in which the tape is difficult to move in the front and back direction when the tape is cut.

  As shown in FIG. 11, the first housing part 200 and the second housing part 206 are arranged inside the main body 20. The first housing part 200 and the second housing part 206 are arranged in the left-right direction via the partition wall 207. As will be described later, the first accommodating portion 200 accommodates the ratchet portion 40 of the tape feeding portion 4, the link member 42, the rotation restricting member 43, and the pawl member releasing portion 5. The second housing portion 206 accommodates the sprocket 41 of the tape feeding portion 4. The common rotating shaft 49 of the tape feeding unit 4 is supported by the partition wall 207. In the first housing part 200, a rotation restricting member mounting wall 200a and a first pawl member mounting wall (not shown) are arranged.

[Tape feeding unit 4]
FIG. 12 is a perspective view of the tape feeding portion and the pawl member releasing portion of the tape cutting device according to the present embodiment. FIG. 13 is an exploded perspective view of the tape feeding portion and the pawl member releasing portion. FIG. 14 is an exploded perspective view of the vicinity of the rotation regulating member of the tape feeding unit. FIG. 15 is an exploded perspective view of the tape feeding unit near the common rotating shaft.

  As shown in FIGS. 12 to 15, the tape feeding unit 4 includes a ratchet unit 40, a sprocket 41, a link member 42, a rotation regulating member 43, and a common rotating shaft 49. The common rotating shaft 49 extends in the left-right direction. The common rotating shaft 49 passes through the partition wall 207.

  Hereinafter, the direction in which the tape 9 is fed from the front (upstream side) to the rear (downstream side) of the rotation direction of the common rotating shaft 49 is referred to as “forward direction (upward direction → backward → downward → forward direction)”. On the other hand, the direction in which the tape 9 is fed from the rear to the front is referred to as “reverse direction (the direction in which the top 9 rotates in the forward direction → the lower direction → the rear direction)”.

  As shown in FIG. 11, the sprocket 41 is housed in the second housing portion 206. The sprocket 41 is fixed to the left end of the common rotating shaft 49. On the outer peripheral surface of the sprocket 41, feed dogs 410 are arranged at predetermined pitches. The feed dog 410 near the upper edge of the sprocket 41 enters the groove of the guide groove 205 from the feed dog protrusion hole 202. As shown in FIG. 4, the feed dog 410 is engaged with the feed hole 900 of the tape 9 inside the guide groove 205. For this reason, when the sprocket 41 is rotated, the tape 9 moves in the guide groove 205. On the other hand, when the tape 9 is moved, the sprocket 41 rotates.

  As shown in FIG. 11, the link member 42 is accommodated in the first accommodating portion 200. The link member 42 includes a driven pin 420, an engaged portion 421, a second pawl member support pin 422, and a main body 423.

  The main body 423 is attached to the common rotating shaft 49. The main body 423 is not fixed to the common rotating shaft 49. For this reason, the main body 423, that is, the link member 42 is rotatable with respect to the common rotation shaft 49. A spring 42 a is attached to the main body 423. When the link member 42 is rotated in the forward direction or the reverse direction with respect to the neutral position shown in FIG. 12, a biasing force is generated in the link member 42 to return to the neutral position.

  The driven pin 420 protrudes from the upper left surface of the main body 423 toward the left. The engaged portion 421 is disposed on the upper rear side of the main body 423. As shown by hatching in FIG. 13, an engaged portion 431 of a rotation restricting member 43 described later is engaged with the engaged portion 421. For this reason, the forward rotation of the engaged portion 421 is restricted. The second pawl member support pin 422 protrudes from the lower right surface of the main body 423 toward the right.

  As shown in FIG. 11, the ratchet portion 40 is housed in the first housing portion 200. The ratchet portion 40 includes a gear 400, a first pawl member 401, a second pawl member 402, a spring 401b, and a spring 402b. The first pawl member 401 and the second pawl member 402 are included in the concept of the “pawl member” of the present invention.

  The gear 400 is fixed to the right end of the common rotating shaft 49. The gear 400 is connected to the sprocket 41 via the common rotating shaft 49. The gear 400 and the sprocket 41 rotate integrally. On the outer peripheral surface of the gear 400, the restriction teeth 400a are arranged for each predetermined pitch.

  As shown in FIG. 15, a first pawl member support pin 200ba projects from the right surface of the first pawl member mounting wall 200b of the first housing portion 200. The first pawl member 401 is rotatably attached to the first pawl member support pin 200ba. A release pin 401 a protrudes from the right surface of the first pawl member 401. The spring 401b is interposed between the first pawl member support pin 200ba and the first pawl member 401. The first pawl member 401 meshes with the restriction tooth 400a of the gear 400 by the biasing force of the spring 401b.

  The first pawl member 401 regulates the rotation direction of the gear 400 with respect to the base 2. That is, the first pawl member 401 allows the gear 400 to rotate in the forward direction. On the other hand, the first pawl member 401 prohibits the rotation of the gear 400 in the reverse direction.

  The second pawl member 402 is rotatably attached to the second pawl member support pin 422 of the link member 42. A release pin 402 a protrudes from the right surface of the second pawl member 402. The spring 402 b is interposed between the second pawl member support pin 422 and the second pawl member 402. The second pawl member 402 meshes with the restriction tooth 400a of the gear 400 by the biasing force of the spring 402b.

  The second pawl member 402 regulates the rotation direction of the gear 400 with respect to the link member 42. That is, the second pawl member 402 allows the gear 400 to rotate in the forward direction. On the other hand, the second pawl member 401 prohibits the rotation of the gear 400 in the reverse direction.

  As shown in FIG. 14, a swing shaft 200aa is inserted through the rotation regulating member mounting wall 200a of the first housing part 200. The rotation restricting member 43 includes a driven pin 430, an engaging portion 431, and a main body 433. The main body 433 is attached to the swing shaft 200aa. The driven pin 430 protrudes from the upper left surface of the main body 433 toward the left. The engaging portion 431 is disposed in front of the upper portion of the main body 433. As shown by hatching in FIG. 13, the engaging portion 431 is engaged with the engaged portion 421. A spring 43 a is in contact with the main body 433. The engaging portion 431 is biased forward (in a direction to engage with the engaged portion 421) by a spring 43a.

[Pawl member releasing portion 5]
The pawl member release portion 5 includes an engagement / disengagement lever 50, a spring 51, a bracket 52, a pair of bolts 53, and a pair of washer rings 54. The bracket 52 has a flat plate shape. The bracket 52 is fixed to the right surface of the rotation restricting member mounting wall 200a via a pair of bolts 53 and a pair of washers 54.

  The engagement / disengagement lever 50 has a C-shaped bar shape that bulges forward. The lower end of the engagement / disengagement lever 50 is rotatably attached to the first pawl member support pin 200ba. As shown in FIG. 11, the upper end of the engagement / disengagement lever 50 protrudes upward from the engagement / disengagement lever protrusion hole 208. The front edge of the engagement / disengagement lever 50 is in contact with the release pin 401 a of the first pawl member 401 and the release pin 402 a of the second pawl member 402. For this reason, when the engagement / disengagement lever 50 is swung forward, the first pawl member 401 and the second pawl member 402 can be swung via the release pin 401a and the release pin 402a.

  The spring 51 is interposed between the bracket 52 and the engagement / disengagement lever 50. When the engagement / disengagement lever 50 is swung forward with respect to the neutral position shown in FIG. 12, the engagement / disengagement lever 50 generates a biasing force that returns to the rear.

<Tape cutting method>
Next, a tape cutting method performed using the tape cutting device of this embodiment will be described. FIG. 16 shows a timing chart of the tape cutting method. As shown in FIG. 16, the tape cutting method includes an insertion process, a forward movement process, a backward movement process, and an extraction process.

[Insertion process]
As shown in FIG. 16, in this step, the operator moves the tape 9 to the reference position. Here, the “insertion position” of the tape 9 refers to a position where the feed hole 900 at the tip of the tape 9 abuts the feed dog 410 of the sprocket 41 as shown in FIG. The “insertion end” of the sprocket 41 refers to the angle of the sprocket 41 at the insertion position. The “insertion end” of the gear 400 refers to the angle of the gear 400 at the insertion position. As shown in FIG. 16, when the tape 9 is moved, the sprocket 41 and the gear 400 are rotated with the movement of the tape 9. Hereinafter, the content of this process is demonstrated concretely.

(the first stage)
FIG. 17 shows a transparent right side view in the first stage of the insertion process of the tape cutting method of the tape cutting device of the present embodiment. FIG. 17 corresponds to FIG. FIG. 18 shows an enlarged cross-sectional view in the first stage of the insertion process in the frame XVIII in FIG.

  As shown in FIGS. 17 and 18, in the first stage of this process, an operator (not shown) inserts the tape 9 into the guide groove 205 of the base 2. Specifically, as shown in FIG. 1, the operator inserts the tape 9 into the introduction portion 205 a of the guide groove 205 through the gap between the plate 60 and the base 2. Here, the groove width of the introduction part 205a is set wider than the part of the guide groove 205 other than the introduction part 205a. For this reason, the operator can insert the tape 9 easily.

  As shown in FIGS. 17 and 18, the inserted tape 9 sinks below the upstream pressing member 61 of the tape pressing portion 6. For this reason, the upstream holding member 61 moves upward while compressing the spring 62. Therefore, the urging force of the spring 62 acts on the tape 9 from above via the upstream holding member 61. That is, the tape 9 is sandwiched from above and below by the lower surface of the upstream holding member 61 and the groove bottom surface of the guide groove 205. Therefore, even when the tape has “curl wrinkles” (see FIG. 35B), the “curl wrinkles” can be corrected.

(Second stage)
FIG. 19 shows a transparent right side view of the tape cutting device of this embodiment in the second stage of the insertion process of the tape cutting method. FIG. 19 corresponds to FIG. As shown in FIG. 19, in the second stage of this process, the operator moves forward until the cut position C (virtual line) of the tape 9 and the engraving line A (reference position) of the plate 60 are aligned. The tape 9 is moved from the rear to the rear.

  When moving, the tape 9 passes above the feed dog protruding hole 202. For this reason, the feed dog 410 of the sprocket 41 is engaged with the feed hole 900 of the tape 9. Therefore, as the tape 9 moves, the sprocket 41 rotates in the forward direction. The sprocket 41 and the gear 400 are connected via a common rotating shaft 49. For this reason, when the sprocket 41 rotates in the forward direction, the gear 400 also rotates in the forward direction.

  The first pawl member 401 and the second pawl member 402 allow the gear 400 to rotate in the forward direction. For this reason, rotation of the sprocket 41 and the gear 400 is not prohibited by the first pawl member 401 and the second pawl member 402.

  Moreover, when the tape 9 is accidentally sent until the cut position C passes the score line A, the tape 9 can be returned from the downstream side to the upstream side by operating the pawl member release portion 5. Yes (see the extraction step described later).

[Outward movement process]
As shown in FIG. 16, in this process, when the operator depresses the operation lever 310, first, the position C to be cut of the tape 9 is changed from the reference position A to the cutting position B (position just below the cutter 311f). Move. Next, the tape 9 is pressed by the tape pressing pusher 311c. In addition, the positioning pin 311 e is inserted into the feed hole 900 of the tape 9. That is, the tape 9 is fixed from the up and down direction (front and back direction) and the left and right direction (short direction). Then, the cut position C of the tape 9 is cut by the cutter 311f. Hereinafter, the content of this process is demonstrated concretely.

(the first stage)
FIG. 20 shows a transparent right side view of the tape cutting device of this embodiment in the first stage of the forward movement process of the tape cutting method. FIG. 20 corresponds to FIG. As shown in FIG. 1, in this step, the operator pushes down the operation lever 310 of the operation unit 31 from above to below. The operation lever 310 swings around the swing shaft 303. For this reason, as shown in FIG. 20, the slider 311 slides downward in the accommodating part 300a.

  At this time, the tape feed pusher 311b of the slider 311 is disengaged from the engaged portion 301b of the cover 301 as shown in FIG. As shown in FIG. 6, the tape feed pusher 311 b slides downward in the pusher insertion slit 302 b of the downstream pressing member 302. As shown in FIG. 11, the tape feed pusher 311 b slides downward in the pusher insertion hole 204 of the main body 20. Then, the tape feed pusher 311b moves the first housing portion 200 of the main body 20 downward.

  Here, the lower end portion of the tape feed pusher 311 b of the slider 311 is in contact with the front end of the driven pin 430 of the rotation restricting member 43. Further, the driven pin 430 is disposed rearward of the swing shaft 200aa of the rotation restricting member 43. For this reason, when the slider 311 slides downward, the driven pin 430 is pushed backward by the lower end of the tape feed pusher 311b. That is, the rotation restricting member 43 swings about the swing shaft 200aa against the biasing force of the spring 43a (see FIG. 12). Therefore, the engaging portion 431 of the rotation restricting member 43 is disengaged from the engaged portion 421 of the link member 42.

  Further, the lower end portion of the tape feed pusher 311 b of the slider 311 is in contact with the upper end of the driven pin 420 of the link member 42. Further, the driven pin 420 is disposed behind the common rotating shaft 49. For this reason, when the slider 311 slides downward, the driven pin 420 is pushed downward by the lower end portion of the tape feed pusher 311b. That is, the link member 42 swings in the forward direction about the common rotation shaft 49 against the urging force of the spring 42a (see FIG. 12). Here, the engaging portion 431 of the rotation restricting member 43 is already detached from the engaged portion 421 of the link member 42. For this reason, the swing of the link member 42 is not restricted by the rotation restricting member 43.

(Second stage)
FIG. 21 shows a transparent right side view of the tape cutting device of the present embodiment in the second stage of the forward movement process of the tape cutting method. FIG. 21 corresponds to FIG. When the operator further depresses the operation lever 310 of the operation unit 31, the slider 311 slides further downward. For this reason, as shown in FIG. 21, the link member 42 swings in the forward direction.

  Here, the second pawl member 402 prohibits the rotation of the gear 400 in the reverse direction. For this reason, the gear 400 cannot rotate in the opposite direction relative to the link member 42. Therefore, the gear 400 also rotates in the forward direction together with the link member 42. In this case, the gear 400 rotates in the forward direction with respect to the first pawl member 401. For this reason, the rotation of the gear 400 is allowed by the first pawl member 401.

  The gear 400 and the sprocket 41 are connected via a common rotating shaft 49. For this reason, when the gear 400 rotates in the forward direction, the sprocket 41 also rotates in the forward direction. The feed dog 410 of the sprocket 41 and the feed hole 900 of the tape 9 are engaged. Therefore, when the sprocket 41 rotates in the forward direction, the tape 9 is fed from the front toward the rear.

  FIG. 22 shows an enlarged view in the frame XXII of FIG. In FIG. 22, the tape feed pusher 311b is omitted. As shown in FIG. 22, in the second stage of the forward movement process, the slider 311 slides downward until the positioning pin 311e approaches the positioning pin insertion hole 302a (see FIG. 6) of the downstream pressing member 302. Here, a gap L <b> 1 is secured between the downstream pressing member 302 and the tape 9. That is, the downstream pressing member 302 is not in contact with the tape 9.

(Third stage)
FIG. 23 shows a transparent right side view of the tape cutting device of the present embodiment in the third stage of the forward movement process of the tape cutting method. FIG. 23 corresponds to FIG. When the operator further depresses the operation lever 310 of the operation unit 31, the slider 311 slides further downward. However, as shown in FIG. 23, when the link member 42 swings, the driven pin 420 is displaced forward with respect to the lower end portion of the tape feed pusher 311b. That is, the driven pin 420 is disengaged from the track of the lower end portion of the tape feeding pusher 311b. For this reason, the pressing force is not applied to the driven pin 420 from the tape feed pusher 311b. Therefore, the swinging of the link member 42, the gear 400, and the sprocket 41 stops. At the same time, the movement of the tape 9 stops. The cut position C of the tape 9 stops at the cutting position B.

  Thus, the distance from the reference position A to the cutting position B corresponds to the swing distance of the link member 42, the gear 400, and the sprocket 41. That is, the distance from the reference position A to the cutting position B and the feed amount of the tape 9 by the tape feed section 4 are the same. The distance from the reference position A to the cutting position B corresponds to an integral multiple of the pitch of the restriction teeth 400a of the gear 400.

  FIG. 24 shows an enlarged view in the frame XXIV of FIG. In FIG. 24, the tape feed pusher 311b is omitted. As shown in FIG. 24, even if the tape 9 stops, the slider 311 continues to slide downward. For this reason, the tape pressing pusher 311c of the slider 311 presses the downstream pressing member 302 from above against the urging force of the spring 311d (see FIG. 7). The downstream pressing member 302 moves downward while consuming the gap L1 shown in FIG. The downstream pressing member 302 presses the tape 9 from above. The tape 9 is sandwiched between the lower surface of the downstream pressing member 302 and the groove bottom surface of the guide groove 205. For this reason, even if the tape has “curl wrinkles” (see FIG. 35B), the “curl wrinkles” can be corrected.

  As shown in FIG. 23, the front portion of the tape 9 is sandwiched between the lower surface of the upstream holding member 61 and the groove bottom surface of the guide groove 205. For this reason, the tape 9 stopped at the cutting position B is fixed from two directions in the front-rear direction.

  As shown in FIG. 24, the positioning pin 311e engages with the feed hole 900 of the tape 9 from above. As shown in FIG. 23, the feed dog 410 of the sprocket 41 is engaged with the feed hole 900 in the front portion of the tape 9. For this reason, the tape 9 stopped at the cutting position B is fixed from the left-right direction (short direction) at two places in the front-rear direction.

(Fourth stage)
FIG. 25 is a transparent right side view of the tape cutting device of this embodiment in the fourth stage of the forward movement process of the tape cutting method. FIG. 25 corresponds to FIG. When the operator further depresses the operation lever 310 of the operation unit 31, the slider 311 slides further downward. However, the tape 9 remains stopped.

  FIG. 26 shows an enlarged view in the frame XXVI of FIG. In FIG. 26, the tape feed pusher 311b is omitted. As shown in FIG. 26, the positioning pin 311e enters the feed hole 900 of the tape 9 more deeply. As shown in FIG. 7, the tape pressing pusher 311c can be immersed in the lower surface of the main body 311a against the urging force of the spring 311d. For this reason, the tape pressing pusher 311c is immersed in the main body 311a in accordance with the amount of the positioning pin 311e entering. The urging force of the spring 311d is increased by the immersion of the tape pressing pusher 311c. For this reason, the clamping force from the up-down direction with respect to the tape 9 becomes large.

(Fifth stage)
FIG. 27 shows a transparent right side view of the tape cutting device of the present embodiment in the fifth stage of the forward movement process of the tape cutting method. FIG. 27 corresponds to FIG. When the operator further depresses the operation lever 310 of the operation unit 31, the slider 311 slides further downward. However, the tape 9 remains stopped.

  FIG. 28 shows an enlarged view in the frame XXVIII of FIG. In FIG. 28, the tape feed pusher 311b is omitted. As shown in FIG. 28, the positioning pin 311 e enters deeper into the feed hole 900 of the tape 9. The pressing force of the tape pressing pusher 311c against the tape 9 increases according to the amount of the positioning pin 311e entering. The cutter 311 f cuts the cut position C of the tape 9 while entering the cutter insertion hole 203 of the main body 20.

[Returning process]
As shown in FIG. 16, in this step, the operator releases the operation lever 310 to move the tape pressing pusher 311c, the positioning pin 311e, the cutter 311f, and the link member 42 backward. Hereinafter, the content of this process is demonstrated concretely.

(the first stage)
FIG. 29 is a transparent right side view of the tape cutting device of the present embodiment in the first stage of the backward movement process of the tape cutting method. FIG. 29 corresponds to FIG. When the operator releases the operation lever 310 of the operation unit 31, the operation lever 310 swings upward by the biasing force of the spring 304 (see FIG. 6). For this reason, the slider 311 slides upward.

  When the slider 311 slides upward, the positioning pin 311e is retracted from the feed hole 900 of the front portion 9a of the tape 9 and the positioning pin insertion hole 302a of the downstream pressing member 302. Further, the tape pressing pusher 311 c is separated from the downstream pressing member 302. Further, the downstream pressing member 302 is separated from the front portion 9 a of the tape 9 by the urging force of the spring. Further, the cutter 311f moves upward.

  Further, when the slider 311, that is, the tape feed pusher 311 b slides upward, the driven pin 420 can enter below the tape feed pusher 311 b. For this reason, the link member 42 is swung in the reverse direction by the biasing force of the spring 42a (see FIG. 12). Here, the second pawl member 402 allows the gear 400 to rotate in the forward direction. For this reason, the link member 42 and the second pawl member 402 swing in the opposite direction with respect to the gear 400. On the other hand, the first pawl member 401 prohibits the rotation of the gear 400 in the reverse direction. For this reason, even if the link member 42 and the second pawl member 402 swing in the opposite directions, the gear 400 does not move. Therefore, the sprocket 41 and the front portion 9a of the cut tape 9 are also immovable.

(Second stage)
FIG. 30 shows a transparent right side view of the tape cutting device of the present embodiment in the second stage of the backward movement process of the tape cutting method. FIG. 30 corresponds to FIG. In this stage, the operating lever 310 is further swung upward by the biasing force of the spring 304 (see FIG. 6). For this reason, the slider 311 slides further upward. When the slider 311 slides upward, the rotation restricting member 43 swings due to the urging force of the spring 43a (see FIG. 12). Then, the engaging portion 431 engages with the engaged portion 421 of the link member 42. By the engagement, the forward swing of the link member 42 is prohibited.

[Removal process]
As shown in FIG. 16, in this step, the operator pulls out the tape 9 from the tape cutting device 1 by pulling the engagement / disengagement lever 50 forward. Hereinafter, the content of this process is demonstrated concretely.

  In addition, this process can also be performed by “the switching operation from the closed mode to the open mode” described later.

(the first stage)
FIG. 31 is a transparent right side view of the tape cutting device of the present embodiment in the first stage of the take-out process of the tape cutting method. FIG. 31 corresponds to FIG. As shown in FIG. 31, when the operator pulls the engagement / disengagement lever 50 forward, the engagement / disengagement lever 50 swings around the first pawl member support pin 200ba. Here, the lower edge (C-shaped outer edge) of the engagement / disengagement lever 50 is in contact with the release pin 401 a of the first pawl member 401 and the release pin 402 a of the second pawl member 402. For this reason, when the engagement / disengagement lever 50 swings, the first pawl member 401 swings around the first pawl member support pin 200ba. In addition, the second pawl member 402 swings around the second pawl member support pin 422. For this reason, the first pawl member 401 and the second pawl member 402 are disengaged from the gear 400. Therefore, the gear 400 and the sprocket 41 can freely rotate not only in the forward direction but also in the reverse direction.

(Second stage)
FIG. 32 shows a transparent right side view of the tape cutting device of the present embodiment in the second stage of the removal process of the tape cutting method. FIG. 32 corresponds to FIG. As shown in FIG. 32, in this stage, the operator pulls the front portion 9 a of the tape 9 forward from the tape cutting device 1 with the engagement / disengagement lever 50 being pulled. In addition, the operator pulls the rear portion 9 b of the tape 9 backward from the tape cutting device 1.

  As described above, according to the tape cutting device 1 of the present embodiment, the tape 9 can be cut without using electric power only by the human power of the operator.

<Operations when switching the mode of the tape cutting device>
Next, the movement at the time of switching from the closed mode to the open mode of the tape cutting device of this embodiment will be described. FIG. 33 is a partial cross-sectional view as seen from the front in the closed mode of the tape cutting device of the present embodiment. FIG. 34 is a partial cross-sectional view as seen from the front in the open mode of the tape cutting device. The closed mode is used when the tape 9 is cut. The open mode is used when the cut tape 9 is taken out from the tape cutting device 1 or when maintenance (for example, cleaning of the guide groove 205) is performed.

  As shown in FIG. 33, in the closed mode, the spring 81 biases the stopper main body 80 in a direction in which the engaging portion 80a protrudes into the accommodating portion 300a. However, the lower end portion 800 of the stopper main body 80 is in contact with the upper surface of the main body 20 of the base 2. For this reason, the stopper main body 80 does not swing. Therefore, the slider 311, that is, the cutter 311 f can move in the housing portion 300 a without interfering with the engaging portion 80 a.

  As shown in FIGS. 33 and 34, when the opening / closing part 30 is opened upward about the swinging shaft 21, the tape cutting device 1 is switched from the closed mode to the open mode. As shown in FIG. 34, in the open mode, the lower end portion 800 of the stopper main body 80 is separated from the upper surface of the main body 20 of the base 2. For this reason, the stopper body 80 is swung by the urging force of the spring 81. Therefore, the engaging part 80a protrudes into the accommodating part 300a. When viewed from the reciprocating direction of the slider 311, an overlap margin L <b> 2 exists between the engaging portion 80 a and the slider 311. For this reason, the movement of the slider 311 in the accommodating part 300a is regulated by the engaging part 80a. Therefore, in the open mode, the cutter 311f is held in the housing portion 300a.

  Note that switching from the open mode to the closed mode is performed by closing the opening / closing unit 30 as shown in FIG. 34 to FIG. 33.

<Effect>
Next, the effect of the tape cut device 1 of this embodiment is demonstrated. The tape cutting device 1 of this embodiment includes an upstream pressing member 61 and a downstream pressing member 302. For this reason, when the tape 9 is cut, the tape 9 hardly moves in the vertical direction. Therefore, the cutting accuracy of the tape 9 can be improved. Even if the tape 9 has “curl wrinkles”, the “curl wrinkles” can be corrected. Moreover, the tape 9 can be fixed from the up-down direction (front and back direction) at two places in the longitudinal direction of the tape 9.

  Further, according to the tape cutting device 1 of the present embodiment, when the tape 9 is cut, the positioning pin 311 e is engaged with the feed hole 900 of the tape 9. In addition, the feed dog 410 of the sprocket 41 is engaged with the feed hole 900 of the tape 9. For this reason, when the tape 9 is cut, the tape 9 hardly moves in the left-right direction. Therefore, the cutting accuracy of the tape 9 can be improved. Moreover, the tape 9 can be fixed from the left-right direction (short direction) at two places in the longitudinal direction of the tape 9.

  Moreover, as shown in FIG. 17, in order to ensure safety, the cutting position B is arranged at a position where it cannot be visually recognized from the outside. For this reason, it is difficult to visually confirm that the cut position C and the cut position B are aligned.

  In this regard, according to the tape cutting device 1 of the present embodiment, the distance between the reference position A and the cutting position B matches the feed amount of the tape 9 by the tape feed unit 4. For this reason, the operator can reliably feed the cut position C of the tape 9 to the cutting position B by aligning the cut position C of the tape 9 with the reference position A and pushing down the operation lever 310 for a predetermined stroke. be able to. In other words, the cut position C and the cut position B of the tape 9 can be aligned without visual confirmation. For this reason, the tape 9 can be cut at a desired position (for example, between the component housing portion 901 containing the electronic components and the empty component housing portion 901). Therefore, there is little possibility that the empty component housing portion 901 is connected to the tape 9 after cutting (the tape 9 to be used). Moreover, there is a small possibility that the component housing portion 901 containing the electronic components is connected to the tape 9 after cutting (the tape 9 that is not used). Moreover, since the cut position C and the cut position B can be aligned without visual confirmation, the safety is high.

  Further, according to the tape cutting device 1 of this embodiment, the operator can manually move the operation lever 310 to feed the tape 9 and cut the tape 9. For this reason, even if there is no supply of electricity, the tape 9 can be accurately cut.

  Further, according to the tape cutting device 1 of the present embodiment, the feed amount of the tape 9 by the tape feed section 4 is set to an integral multiple of the pitch of the restriction teeth 400a of the gear 400. For this reason, the to-be-cut position C of the tape 9 can be reliably aligned with the cutting position B. Moreover, the sprocket 41 is rotated stepwise by the ratchet portion 40. For this reason, it is easy to align the cut position C of the tape 9 with the cut position B. Further, the first pawl member 401 and the second pawl member 402 prohibit the rotation of the gear 400 in the reverse direction. For this reason, in the state in which the first pawl member 401 and the second pawl member 402 are engaged with the gear 400, the possibility that the tape 9 is fed in the reverse direction is small.

  Further, the tape cutting device 1 of the present embodiment can be switched between a closed mode and an open mode. In the closed mode, the cutter 311f can protrude from the housing portion 300a. For this reason, the tape 9 can be cut. On the other hand, in the open mode, the cutter 311f cannot protrude from the housing portion 300a. For this reason, safety is high.

  Further, according to the tape cutting device 1 of the present embodiment, as shown in FIG. 28, the cutter insertion hole 203 into which the cutter 311f after cutting the tape 9 enters is arranged. Therefore, the entire cut position C of the tape 9 is cut by shearing. Therefore, the cutting accuracy of the tape 9 can be improved.

  Further, according to the tape cutting device 1 of the present embodiment, as shown in FIG. 24, the downstream pressing member 302 comes into contact with the tape 9 from the direction perpendicular to the surface (upper surface) of the tape 9 (directly above). . For this reason, the load in the short direction (left-right direction) of the tape 9 does not easily act on the tape 9 from the downstream pressing member 302. For this reason, there is little possibility that the tape 9 will run away in the short direction. Therefore, the cutting accuracy of the tape 9 can be improved.

  Further, according to the tape cutting device 1 of the present embodiment, the downstream pressing member 302 is in contact with the tape 9 in the immediate vicinity of the cutting position B as shown in FIG. Further, a positioning pin 311e is inserted into the feed hole 900 in the immediate vicinity of the cutting position B. For this reason, the cutting accuracy of the tape 9 can be improved as compared with the case where the tape 9 is positioned only at a position separated from the cutting position B.

  Further, according to the tape cutting device 1 of the present embodiment, as shown in FIG. 17, the insertion position and the reference position A are arranged from the upstream side (front) to the downstream side (rear). From the insertion position to the reference position A, the tape 9 is fed by the operator's own power. Here, the distance between the insertion position and the reference position A is set to an integral multiple of the pitch of the restriction teeth 400a of the gear 400. When the first pawl member 401 and the second pawl member 402 get over the restriction tooth 400a of the gear 400, the reaction force applied to the operator increases momentarily. In addition, a “click” sound is heard when the control tooth 400a of the gear 400 is overcome. The operator can recognize that the tape has reached the reference position based on the number of times that the reaction force is sensed by tactile sense and the number of times that the sound of “click” is heard. For this reason, the to-be-cut position C of the tape 9 can be easily and reliably sent to the reference position A.

<Others>
The embodiment of the tape cutting device of the present invention has been described above. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible.

  In the above embodiment, the distance between the reference position A and the cutting position B is matched with the feed amount of the tape 9 by the tape feed unit 4, but the distance is an integral multiple of the feed amount of the tape 9. I just need it. In this case, the operator may press down the operation lever 310 a plurality of times.

  Further, the pitch of the feed holes 900 and the pitch of the component accommodating portions 901 in the tape 9 are not particularly limited. For example, the pitch may conform to the standard of JIS C 0806-3. In the above embodiment, the downstream pressing member 302 is disposed in the opening / closing part 30. However, the downstream pressing member 302 may be disposed on the main body 20 of the base 2.

  Further, the distance between the insertion position and the reference position A and the distance between the reference position A and the cutting position B are not particularly limited. For example, you may change suitably according to the specification of the tape 9, etc. The position of the cut position C of the tape 9 is not particularly limited. For example, you may change suitably according to the specification of the tape 9, etc. Further, the cut position C may be set so as not to cross the feed hole 900.
