Description

  The present invention relates to a component supply apparatus and a component supply method for supplying a component to a nozzle of a transfer head of a component mounting apparatus.

  Conventionally, a carrier tape has been used to supply components to a nozzle of a transfer head of a component mounting apparatus. The carrier tape includes a base tape in which a plurality of recessed or embossed component receiving portions for storing components are formed side by side in the longitudinal direction of the tape, and a base so as to cover the plurality of component receiving portions in a state where the components are stored. And a top tape attached to the tape. The top tape is peeled from the base tape so that the nozzle of the transfer head of the component mounting apparatus can adsorb the components in the component accommodating portion of the carrier tape.

  For example, Patent Document 1 discloses that the top tape is peeled off from the base tape by using a blade having a cutting edge. Specifically, a blade is disposed on a tape path of a carrier tape that is fed in the tape longitudinal direction (tape feeding direction). When the blade edge of the blade enters the tape in the longitudinal direction between the base tape and the top tape from the front end side of the moving carrier tape, the top tape is peeled off from the base tape. In addition, the component supply apparatus described in patent document 1 is comprised so that the part of the one side of the tape width direction of a top tape may peel from a base tape.

  Moreover, in the case of the component supply apparatus described in Patent Document 1, a plurality of carrier tapes are sequentially and automatically fed in the tape feeding direction. Specifically, the plurality of carrier tapes are sequentially fed so that the trailing edge of the preceding carrier tape in the tape feeding direction follows the leading edge of the succeeding carrier tape in the tape feeding direction.

  The component supply apparatus described in Patent Document 1 is configured to wait until the timing at which the feeding is started in a state where the subsequent carrier tape is stacked on the preceding carrier tape that is fed in the tape feeding direction. ing.

  Specifically, the preceding carrier tape is fed in the tape feeding direction on the tape running surface of the tape guide portion on which the carrier tape runs, and is directed toward the tape guide portion by a pad disposed above the tape running direction. It is energized. That is, the preceding carrier tape is fed in the tape feeding direction so as to interrupt between the tape running surface of the tape guide portion and the pad.

  On the other hand, the succeeding carrier tape is stacked on the preceding carrier tape that is fed in the tape feeding direction, and waits when the front end in the tape feeding direction comes into contact with the pad.

  When the trailing edge of the preceding carrier tape in the tape feeding direction passes the leading edge of the succeeding carrier tape (that is, when the overlapping state is eliminated), the tape of the tape guide portion generated by the trailing edge of the preceding carrier tape intervening The subsequent carrier tape enters the gap between the running surface and the pad. In this way, the subsequent carrier tape is fed in the tape feeding direction following the preceding carrier tape.

  However, in the case of the component supply apparatus described in Patent Document 1, when there is no carrier tape between the tape running surface of the tape guide portion and the pad, there is a possibility that a thin carrier tape cannot be interrupted and fed. There is. Alternatively, when the preceding carrier tape is relatively thin and the succeeding carrier tape is relatively thick, the tape running surface and the pad of the tape guide portion caused by the rear end in the tape feeding direction of the thin preceding carrier tape being interposed There is a possibility that a thick subsequent carrier tape cannot enter the narrow gap between the two.

  The component supply apparatus 10 is configured to sequentially feed a plurality of carrier tapes 200 in the tape feeding direction A toward the component supply position Q1. Specifically, the plurality of carrier tapes 200 are sequentially moved in the tape feed direction so that the rear end of the tape feed direction A of the preceding carrier tape 200 follows the front end of the subsequent carrier tape 200 in the tape feed direction A. Send to A. In the following description, in order to distinguish between the preceding carrier tape 200 and the succeeding carrier tape 200, “′” (apostrophe) is given to the reference numerals related to the succeeding carrier tape.

  As shown in FIG. 1, the component supply apparatus 10 is configured to wait for the subsequent carrier tape 200 ′ in a state of being superimposed on the preceding carrier tape 200 until the timing at which the feeding is started.

  FIG. 3 is a partially enlarged view of the component supply apparatus 10 showing the vicinity of the subsequent tape standby position Q3, which is a position where the subsequent carrier tape 200 'waits until the start of feeding thereof.

  As shown in FIG. 3, the subsequent carrier tape 200 ′ loaded into the tape loading slot 12 a stands by in a state where it is stacked on the upper surface 200 a of the preceding carrier tape 200 fed in the tape feeding direction A. The subsequent carrier tape 200 'stands by in a state where its feed hole 208' is engaged with the teeth 14a of the sprocket 14 located on the upstream side in the tape feed direction A. That is, the position that can be engaged with the sprocket 14 is the subsequent tape standby position Q3 where the subsequent carrier tape 200 'waits.

  When the succeeding carrier tape 200 ′ is waiting at the succeeding tape waiting position Q3 with the teeth 14a of the sprocket 14 engaged with the feed hole 208 ′, the succeeding carrier tape 200 ′ is positioned below the succeeding carrier tape 200 ′. The preceding carrier tape 200 fed in the tape feeding direction A toward the component supply position Q1 is not engaged with the sprocket 14. Further, the sprocket 14 engaged with the subsequent carrier tape 200 ′ in the standby state stops rotating (tape feeding is stopped) until the standby of the subsequent carrier tape 200 ′ is released. ). At the start timing of feeding the succeeding carrier tape 200 '(details will be described later), the sprocket 14 rotates and starts feeding the succeeding carrier tape 200' in the tape feeding direction.

  As shown in FIG. 3, the succeeding carrier tape 200 ′ is taped by the succeeding tape restraining mechanism 30 so as to wait in a state of being overlapped (contacted) with the preceding carrier tape 200 fed in the tape feeding direction A. Movement in the feed direction A is restricted. In other words, the subsequent tape stopping mechanism 30 restricts the subsequent carrier tape 200 ′ from moving along with the preceding carrier tape 200 in the tape feeding direction A. Hereinafter, the configuration of the subsequent tape restraining mechanism 30 and related components of the component supply device will be described with reference to FIGS. 3 and 4A to 4F.

  As shown in FIG. 3, the trailing tape stopping mechanism 30 is a stopper that contacts the trailing carrier tape 200 ′ on the leading carrier tape 200 and restricts the movement of the trailing carrier tape 200 ′ in the tape feeding direction A. It has the part 32 and the lock part 34 which locks the stopper part 32 releasably.

  The preceding and succeeding carrier tapes 200 pass through a tape guide portion 12d configured by a space between a lower tape traveling surface 12b and an upper tape traveling surface 12c formed in the main body portion 12 of the component supply device 10. Thus, the tape is guided in the tape feeding direction A along the tape path P shown in FIG. The succeeding tape restraining mechanism 30 is disposed above the tape guide portion 12d and downstream of the sprocket 14 in the tape feeding direction A. The lower tape running surface 12b of the tape guide portion 12d faces the lower surface 200b of the carrier tape 200 so as to be able to support the lower surface side of the carrier tape 200, and the upper tape running surface 12c is the upper surface 200a of the carrier tape 200 (that is, the top It faces the main surface 204a) of the base tape 204 to which the tape 206 is attached.

  In the case of the present embodiment, the stopper portion 32 of the subsequent tape restraining mechanism 30 is formed in the tape width direction (X axis) of the carrier tape 200 fed in the tape feeding direction A on the lower tape running surface 12b of the tape guide portion 12d. It is a member that can freely swing around a swing center line S1 (corresponding to the “first swing center line” in the claims) extending in the direction. For example, the stopper portion 32 is swingably supported by a support pin (not shown) provided in the main body portion 12 of the component supply device 10 and extending in the X-axis direction. The stopper portion 32 has a free end on the upstream side in the tape feed direction A with respect to the swing center line S1, and a free end on the downstream side in the tape feed direction A with respect to the swing center line S1, A trailing tape restraining portion 32a provided on the upstream free end side and an engagement portion 32d provided on the downstream free end side are provided.

  As shown in FIG. 3, the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30 is in contact with the front end 210 ′ of the succeeding carrier tape 200 ′ on the preceding carrier tape 200 in the tape feeding direction A. Thus, the movement of the subsequent carrier tape 200 ′ in the tape feeding direction A is stopped. By this succeeding tape restraining portion 32a, the succeeding carrier tape 200 'can wait at the succeeding tape waiting position Q3 while being superposed on the preceding carrier tape 200.

As shown in FIG. 3, when the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30 is in contact with the front end 210 ′ in the tape feeding direction A of the succeeding carrier tape 200 ′, the succeeding tape restraining portion. 32 a is also in contact with the upper surface 200 a of the preceding carrier tape 200. In the case of the present embodiment, the succeeding tape stopper a32 descends and comes into contact with the upper surface 200a of the preceding carrier tape 200 by its own weight and maintains the contact state. That is, although the details will be described later, when the stopper portion 32 is not locked by the lock portion 34 and can be freely swung, the stopper portion 32 is configured such that the subsequent tape stopping portion 32a moves downward.
Accordingly, even when the subsequent carrier tape 200 ′ is thin, the subsequent carrier tape 200 ′ is suppressed from passing between the subsequent tape stopping portion 32a and the upper surface 200a of the preceding carrier tape 200.

  The engagement portion 32b of the stopper portion 32 of the subsequent tape stopping mechanism 30 is a portion that comes into contact with the lock portion 34 when locked by the lock portion 34, as will be described in detail later.

  The subsequent tape detection mechanism (subsequent tape detection unit) 40 for detecting the state in which the subsequent carrier tape 200 ′ is in contact with the subsequent tape stop portion 32 a of the stopper portion 32 of the subsequent tape stop mechanism 30 is provided with the component supply device 10. May be provided.

  The subsequent tape detection mechanism 40 is in a state where the subsequent carrier tape 200 ′ is waiting at the subsequent tape standby position Q3, that is, the front end 210 ′ of the subsequent carrier tape 200 ′ in the tape feeding direction A is the stopper of the subsequent tape stopping mechanism 30. It is configured to detect the state of contact with the subsequent tape stop portion 32a of the portion 32. Therefore, in the subsequent tape detection mechanism 40, the subsequent carrier tape 200 ′ is in contact with the probe portion 42 that contacts the front end 210 ′ of the subsequent carrier tape 200 ′ that overlaps the previous carrier tape 200 in the tape feeding direction A. And a sensor 44 that detects the movement of the probe unit 42 caused by the above.

  The probe portion 42 of the subsequent tape detection mechanism 40 is provided on the free end side on the upstream side in the tape feeding direction A of the stopper portion 32 of the subsequent tape stop mechanism 30 and swings extending in the tape width direction (X-axis direction). It is supported by the stopper portion 32 so as to be freely swingable around a center line S2 (corresponding to “third swing center line” in the claims). For example, the probe portion 42 can swing on a support pin (not shown) that is attached to the free end side upstream of the tape feed direction A of the stopper portion 32 and extends in the tape width direction (X-axis direction). It is supported.

  Further, the probe portion 42 of the subsequent tape detection mechanism 40 has a free end on the upstream side in the tape feed direction A with respect to the swing center line S2, and a free end on the downstream side in the tape feed direction A with respect to the swing center line S2. A trailing tape contact portion 42a that is provided on the upstream free end side and is in contact with the front end 210 ′ of the subsequent carrier tape 200 ′ in the tape feeding direction A, and provided on the downstream free end. And a detection target part 42b detected by the sensor 44.

  The subsequent tape contact portion 42a of the probe portion 42 of the subsequent tape detection mechanism 40 is earlier than the subsequent tape stop portion 32a of the stopper portion 32 of the subsequent tape stop mechanism 30 in the tape feed direction A of the subsequent carrier tape 200 ′. It is comprised so that front end 210 'may be contacted. This will be described with reference to FIGS. 3, 4A, and 4B.

  FIG. 4A is a partially enlarged view of the component supply device 10 showing the vicinity of the subsequent tape standby position Q3 before the preceding carrier tape 200 is put into the main body 12 of the component supply device 10. FIG. FIG. 4B is a component supply showing the vicinity of the succeeding tape standby position Q3 immediately before the front end 210 of the preceding carrier tape 200 in the tape feeding direction A passes below the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30. 3 is a partially enlarged view of the device 10. FIG.

  4A and 4B also show that the front end 210 'of the succeeding carrier tape 200' in the tape feeding direction A is not in contact with the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30. FIG.

  4A and 4B, the subsequent tape contact portion 42a of the probe 42 of the subsequent tape detection mechanism 40 and the subsequent tape stop portion 32a of the stopper portion 32 of the subsequent tape stop mechanism 30 are arranged in the tape width direction (X axis). Direction). Further, the subsequent tape contact portion 42 a of the probe portion 42 of the subsequent tape detection mechanism 40 is positioned on the upstream side in the tape feeding direction A as compared with the subsequent tape stop portion 32 a of the stopper portion 32 of the subsequent tape stop mechanism 30. Therefore, the front end 210 ′ of the succeeding carrier tape 200 ′ moving in the tape feeding direction A on the preceding carrier tape 200 is in contact with the succeeding tape contact portion 42a of the probe portion 42 of the succeeding tape detecting mechanism 40. While maintaining the contact state with the subsequent tape contact portion 42 a, the subsequent tape stop portion 32 a of the stopper portion 32 of the subsequent tape stop mechanism 30 can be contacted.

  The front end 210 ′ of the subsequent carrier tape 200 ′ in the tape feeding direction A contacts the subsequent tape contact portion 42 a of the probe portion 42 of the subsequent tape detection mechanism 40, and then the subsequent tape stop of the stopper portion 32 of the subsequent tape stop mechanism 30. By contacting the portion 32a, the probe portion 42 swings around the swing center line S2 (swings counterclockwise in the figure). Thereby, the detection target portion 42b provided on the free end side downstream in the tape feeding direction A moves with respect to the swing center line S2.

  Specifically, in the case of the present embodiment, the subsequent tape contact portion 42a on the upstream side in the tape feed direction A with respect to the swing center line S2 is downstream in the tape feed direction A due to contact with the subsequent carrier tape 200 ′. The probe portion 42 is configured such that when it moves to the side, the detection target portion 42b on the downstream side moves substantially upward with respect to the swing center line S2.

  The sensor 44 detects a substantially upward movement of the detection target portion 42b of the probe portion 42 caused by the contact between the front end 210 'of the subsequent carrier tape 200' in the tape feeding direction A and the subsequent tape contact portion 42a. In the case of the present embodiment, the sensor 44 includes a detection area 44a and is configured to detect an object in the detection area 44a. As shown in FIGS. 4A and 4B, when the subsequent carrier tape 200 ′ is not in contact with the subsequent tape contact portion 42 a of the probe portion 42, the detection target portion 42 b exists in the detection area 44 a of the sensor 44. On the other hand, as shown in FIG. 3, when the subsequent carrier tape 200 ′ is in contact with the subsequent tape contact portion 42 a of the probe portion 42 and the subsequent tape stop portion 32 a of the stopper portion 32, the detection target portion 42 b is connected to the sensor 44. Located outside the detection area 44a. As a result, the sensor 44 is in a state where the front end 210 ′ of the subsequent carrier tape 200 ′ in the tape feeding direction A is in contact with the subsequent tape stop portion 32 a of the stopper portion 32 of the subsequent tape stop mechanism 30, that is, the subsequent carrier tape. It is possible to detect a state in which 200 ′ is waiting at the subsequent tape standby position Q3.

  The probe unit 42 of the subsequent tape detection unit 40 is configured such that the distance from the swing center line S2 to the detection target unit 42b is longer than the distance from the swing center line S2 to the subsequent tape contact unit 42a. Is preferred. Thereby, compared with the movement amount of the subsequent tape contact part 42a of the probe part 42 which moves by contact with subsequent carrier tape 200 ', the movement amount of the detection target part 42b which arises as a result can be enlarged. As a result, the sensor 44 detects a large movement of the detection target portion 42, so that the front end 200 ′ of the subsequent carrier tape 200 in the tape feeding direction A is in contact with the subsequent tape stopping portion 32 a of the stopper portion 32. Can be detected with high accuracy.

  Also, as shown in FIGS. 4A and 4B, the subsequent tape contact portion 42a cannot be brought into contact with the subsequent carrier tape 200 ′ or moved upward where the contact becomes unstable due to the free swinging of the probe portion 42. The subsequent tape detection unit 40 includes a probe swing limiter 46 that limits the free swing range of the probe unit 42. The probe swing restricting portion 46 is provided in the main body portion 12 of the component supply device 10 and comes into contact with the portion of the probe portion 42 on the downstream side in the tape feeding direction A with respect to the swing center line S2 from below, and the subsequent carrier The subsequent tape contact portion 42a is relatively maintained at a position where it can come into contact with the tape 200 ′. Accordingly, the front end 210 ′ of the subsequent carrier tape 200 ′ can stably contact the subsequent tape contact portion 42 a of the probe portion 42 when contacting the subsequent tape stopping portion 32 a of the stopper portion 32.

  Returning to the description of the subsequent tape stopping mechanism 30 from the subsequent tape detecting mechanism 40, the stopper contact portion 34a of the lock portion 34 of the subsequent tape stopping mechanism 30 can swing as shown in FIGS. 3, 4A, and 4B. It is a movable member that contacts the engaging portion 32b of the stopper portion 32 so as to be separable and locks the stopper portion 32 so that the stopper portion 32 can be released.

  In the case of the present embodiment, the movable lock portion 34 is configured to swing around a swing center line S1 extending in the tape width direction (X-axis direction). That is, the swing center lines of the stopper portion 32 and the lock portion 34 of the subsequent tape stopping mechanism 20 coincide with each other. For example, the stopper portion 32 and the lock portion 34 are swingably supported by a common support pin (not shown). As a result, compared with the case where the stopper portion 32 and the lock portion 34 are arranged in the main body portion 12 of the component supply device 10 so that the respective swing center lines are at different positions, the stopper portion 32 and the lock portion 34 are The arrangement space is made compact (as a result, the component supply device is made compact).

  In the case of this embodiment, as shown in FIG. 3, the lock portion 34 of the swingable trailing tape restraining mechanism 30 has two free ends and is provided on one free end side of the stopper portion 32. A stopper contact portion 34a that contacts the engaging portion 32b so as to be separable, and a preceding tape contact portion 34b that is provided on the other free end side and contacts the preceding carrier tape 200 are provided.

  The stopper contact portion 34a of the lock portion 34 is configured so that the preceding carrier tape 200 is not restrained by the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30 and the lower portion of the succeeding tape restraining portion 32 is moved in the tape feeding direction A. To pass through.

  Specifically, by contacting at least the upper part with the engaging part 32b of the stopper part 32, the stopper contact part 34a of the lock part 34 causes the carrier tape 200 to pass under the subsequent tape stopping part 32a in the tape feeding direction A. As possible, the trailing tape restraining portion 32a of the stopper portion 32 is placed on the lower tape running surface 12b of the tape guide portion 12d (in this embodiment, the raising and lowering tape running surface 50a formed on the lifting block 50 described later). It is retracted upward (on the upper tape running surface 12c side) and locked (fixed). As a result, the preceding carrier tape 200 is not restrained by the succeeding tape restraining portion 32a of the stopper portion 32, and passes between the succeeding tape restraining portion 32a and the ascending / descending tape running surface 50a of the ascending / descending block 50 in the tape feeding direction A. can do.

  The lifting tape traveling surface 50a will be described. The lifting tape traveling surface 50a is a part of the lower tape traveling surface 12b of the tape guide portion 12d and is configured to be movable up and down toward the sprocket 14. Specifically, the lifting tape running surface 50 a is formed on the upper surface of the lifting block 50 that is biased toward the sprocket 14 by a spring 52. Accordingly, as shown in FIG. 4B, when the subsequent carrier tape 200 ′ does not overlap the preceding carrier tape 200, the engagement between the feed hole 208 of the preceding carrier tape 200 and the teeth 14a of the sprocket 14 is performed. The sprocket 14 enables the preceding carrier tape 200 to be fed in the tape feeding direction A. Further, as shown in FIG. 3, when the succeeding carrier tape 200 ′ overlaps the preceding carrier tape 200, the engagement between the feed hole 208 ′ of the succeeding carrier tape 200 ′ and the teeth 14a of the sprocket 14 is maintained. The subsequent carrier tape 200 ′ can be fed in the tape feeding direction A by the sprocket 14.

  The preceding carrier tape 200 that has passed in the tape feeding direction A between the succeeding tape stop portion 32a of the stopper portion 32 and the ascending / descending tape running surface 50a of the tape guide portion 12d (elevating block 50) is the preceding tape contact portion of the lock portion 34. Until contact with 34 b, as shown in FIGS. 4A and 4B, the contact between the engagement portion 32 b of the stopper portion 32 of the subsequent tape stopping mechanism 30 and the stopper contact portion 34 a of the lock portion 34 is maintained.

  As shown in FIGS. 4A and 4B, the preceding tape contact portion 34b of the lock portion 34 with which the preceding carrier tape 200 comes into contact is positioned downstream of the subsequent tape stopping portion 32a of the stopper portion 32 in the tape feeding direction A. To do. The lock portion 34 is positioned below the preceding tape contact portion 34b and faces the lower surface side of the carrier tape 200 (200 ′) to support at least both ends in the tape width direction of the carrier tape 200 (200 ′) from below. A recessed portion 12e into which the preceding tape contact portion 34b of the lock portion 34 can enter from above is formed on the lower tape running surface 12b of the possible tape guide portion 12d. When the engagement portion 32a of the stopper portion 32 and the stopper contact portion 34a of the lock portion 34 are in contact (when the stopper portion 32 is locked by the lock portion 34), the preceding tape contact portion 34b of the lock portion 34 is In the state where at least a part has entered the recess 12e of the lower tape running surface 12b of the tape guide portion 12d, the process waits.

  FIG. 4C shows that the preceding carrier tape 200 that has passed in the tape feed direction A between the trailing tape restraining portion 32a of the stopper portion 32 and the raising / lowering tape running surface 50a of the tape guide portion 12d (elevating block 50) The state immediately after contacting the preceding tape contact portion 34b is shown.

  As shown in FIG. 4B, the preceding tape contact portion 34b of the lock portion 34 in a state where at least a part thereof has entered the recess 12e of the tape guide portion 12d moves on the lower tape running surface 12b of the tape guide portion 12d in the tape feeding direction. When it comes into contact with the preceding carrier tape 200 moving to A, it rides on the upper surface 200a of the preceding carrier tape 200 as shown in FIG. 4C. In the case of the present embodiment, the leading tape contact portion 34b of the lock portion 34 extends, for example, in the tape width direction (X-axis direction) so that it can easily ride on the upper surface 200a of the preceding carrier tape 200. It is composed of a roller 36 that freely rotates around the existing rotation center line.

  As shown in FIG. 4C, the preceding tape contact portion 34b (roller 36) of the lock portion 34 is brought into contact with the upper surface 200a of the preceding carrier tape 200 fed in the tape feeding direction A and supported on the lower surface side by the lower tape running surface 12b. , The lock portion 34 swings about the swing center line S1 (swings counterclockwise in the figure), whereby the stopper contact portion 34a of the lock portion 34 engages with the engagement portion of the stopper portion 32. It is spaced upward from 32b. As a result, the contact between the stopper contact portion 34a of the lock portion 34 and the engagement portion 32b of the stopper portion 32 is released, and the lock of the stopper portion 32 by the lock portion 34 is released.

  When the lock by the lock portion 34 is released, the stopper portion 32 swings around the swing center line S1 (swings counterclockwise in the figure), and the subsequent tape stop portion 32a is the preceding carrier tape. Lowering toward the upper surface 200a of 200, it contacts.

  In the case of the present embodiment, as shown in FIGS. 4A and 4B, the leading tape contact portion 34b (roller 36) of the lock portion 34 is a recess 12e formed on the lower tape running surface 12b of the tape guide portion 12d. The lock portion 34 is urged by a spring 38 in the direction of entering. Instead of the spring 38, the lock portion 34 may be configured such that the preceding tape contact portion 34b enters the lower tape running surface 12b of the tape guide portion 12d by its own weight. In addition, when the component supply device 10 is configured to be usable with the carrier tape 200 including the embossed component accommodating portion 202 (including the embossed portion protruding from the lower surface 200b), the leading tape contact portion 34b of the lock portion 34 The entering recess 12e may be a groove extending in the tape feeding direction A in which the embossed portion of the carrier tape 200 can move in the tape feeding direction A.

  In FIG. 4D, the subsequent carrier tape 200 ′ is loaded into the main body 12 of the component supply apparatus 10, and the front end 210 ′ in the tape feeding direction A is set to the subsequent tape stopping portion 32 a of the stopper portion 32 of the subsequent tape stopping mechanism 30. The state immediately before contact, that is, the state immediately before the subsequent carrier tape 200 ′ waits is shown.

  As shown in FIG. 4D, the succeeding carrier tape 200 ′ has a tape feeding direction A between the upper surface 200a of the preceding carrier tape 200 and the upper tape running surface 12c of the tape guide portion 12d by, for example, an operator's manual operation. Sent to. As shown in FIG. 3, when the front end 210 ′ in the tape feeding direction A comes into contact with the subsequent tape stopping portion 32a of the stopper portion 32 of the subsequent tape stopping mechanism 30, the subsequent carrier tape 200 ′ is moved to the subsequent tape standby position Q3. Waiting at.

  FIG. 4E shows a state immediately after the rear end 212 of the tape feeding direction A of the preceding carrier tape 200 passes below the subsequent tape stop portion 32 a of the stopper portion 32 of the subsequent tape stop mechanism 30.

  As shown in FIG. 4E, when the rear end 212 of the tape feeding direction A of the preceding carrier tape 200 passes below the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30, the preceding carrier tape 200 and the following The overlap of the carrier tape 200 'is eliminated. As a result, the subsequent carrier tape 200 'is disposed on the lower tape running surface 12b of the tape guide portion 12d (the lifting tape running surface 50a of the lifting block 50). At the same time, the succeeding tape stop portion 32a of the stopper portion 32 descends and comes into contact with the lower tape running surface 12b of the tape guide portion 12d (the lifting tape running surface 50a of the lifting block 50). As a result, the movement of the subsequent carrier tape 200 ′ arranged on the lower tape running surface 12b of the tape guide portion 12d is restricted in the tape feeding direction A by the subsequent tape stopping portion 32a of the stopper portion 32, and the subsequent tape standby Continue to wait at position Q3.

  FIG. 4F shows a state immediately after the preceding carrier tape 200 is separated from the preceding tape contact portion 34 b of the lock portion 34 of the subsequent tape stopping mechanism 30.

  As shown in FIG. 4F, when the contact between the preceding carrier tape 200 and the preceding tape contact portion 34b of the lock portion 34 of the succeeding tape stopping mechanism 30 is resolved, the preceding tape contact portion 34b moves downward. Thus, the lock portion 34 swings about the swing center line S1 so as to enter the recess 12e of the lower tape running surface 12b of the tape guide portion 12d (swings clockwise in the figure).

  When the lock portion 34 swings, the stopper contact portion 34a of the lock portion 34a moves downward to contact the engagement portion 32b of the stopper portion 32, and further pushes the engagement portion 32b downward. As a result, the stopper portion 32b swings about the swing center line S1 (swings clockwise in the figure), and the subsequent tape stop portion 32a moves to the lower tape running surface 12b (elevating / lowering) of the tape guide portion 12d. The block 50 moves upwardly away from the lifting tape running surface 50a). As a result, the subsequent carrier tape 200 ′ waiting at the subsequent tape standby position Q3 can pass in the tape feeding direction A between the subsequent tape stopping portion 32a of the stopper portion 32 and the tape running surface 12b of the tape guide portion 12d. Put into state.

  As shown in FIG. 1, the subsequent carrier tape 200 ′ waiting at the subsequent tape standby position Q 3 is fed in the tape feeding direction A by the sensor 60 disposed on the tape path P as shown in FIG. It is automatically started when the rear end 212 of the direction A is detected. That is, when the sensor 60 detects the rear end 212 of the tape feeding direction A of the preceding carrier tape 200, the sprocket 14 starts to rotate and feeding of the subsequent carrier tape 200 ′ in the tape feeding direction A is automatically started. The

  Next, a flow until the preceding carrier tape 200 is loaded into the component supply apparatus 10 and the feeding of the subsequent carrier tape 200 'to be loaded next is automatically started will be described.

  First, as shown in FIG. 4B, until the feed hole 208 of the preceding carrier tape 200 engages with the teeth 14a of the sprocket 14, the preceding carrier tape 200 supplies the parts from the tape insertion port 12a, for example, manually by the operator. It is thrown into the apparatus 10.

  As shown in FIG. 4B, after the feed hole 208 of the preceding carrier tape 200 is engaged with the teeth 14a of the sprocket 14, the rotation of the sprocket 14 is automatically or manually started. As a result, feeding of the preceding carrier tape 200 in the tape feeding direction A is started.

  As shown in FIG. 4C, the front end 210 of the preceding carrier tape 200 fed in the tape feeding direction A by the sprocket 14 is below the following tape stopping portion 32a of the stopper portion 32 of the following tape stopping mechanism 30 and the lower tape running. The preceding tape contact portion 34b (roller 36) of the lock portion 34 rides on the preceding carrier tape 200 that passes between the surface 12b and moves on the lower tape running surface 12b in the tape feeding direction A. Thereby, the lock of the stopper portion 34b is released, and the subsequent tape stopping portion 32a descends and comes into contact with the upper surface 200a of the preceding carrier tape 200.

  As shown in FIG. 1, when the preceding carrier tape 200 sent to the sprocket 14 in the tape feeding direction A reaches the sprocket 16, the sprocket 14 is in a free rotating state, and the preceding carrier tape 200 is fed by the sprocket 16. Is started. Further, after the preceding carrier tape 200 reaches the sprocket 18, the preceding carrier tape 200 is fed in the tape feeding direction A by the two sprockets 16 and 18 that rotate synchronously.

  As shown in FIG. 4D, the succeeding carrier tape 200 'is overlaid on the preceding carrier tape 200 fed in the tape feeding direction A by the sprockets 16 and 18, for example, manually by the operator. Then, as shown in FIG. 3, the subsequent carrier tape 200 ′ has a tape feed direction A until the front end 210 ′ in the tape feed direction A comes into contact with the subsequent tape stop portion 32 a of the stopper portion 32 of the subsequent tape stop mechanism 30. Sent to and pushed. The subsequent tape detection mechanism 40 detects contact between the front end 210 ′ of the subsequent carrier tape 200 ′ in the tape feeding direction A and the subsequent tape stop portion 32 a of the stopper portion 32 of the subsequent tape stop mechanism 30. As a result, the succeeding carrier tape 200 'waits at the succeeding tape standby position Q3 (preparation for automatic feeding of the succeeding carrier tape 200' is completed).

  As shown in FIG. 4E, the rear end 212 of the preceding carrier tape 200 fed in the tape feeding direction A by the sprockets 16 and 18 is below and below the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30. It passes between the side tape running surface 12b. Subsequently, as shown in FIG. 4F, the rear end 212 of the preceding carrier tape 200 moving in the tape feeding direction A on the lower tape running surface 12b passes the preceding tape contact portion 34b (roller 36) of the lock portion 34. Then, the contact between the preceding carrier tape 200 and the preceding tape contact portion 34b is eliminated. Accordingly, the stopper portion 32 is locked by the lock portion 34, and the subsequent tape stop portion 32a of the stopper portion 32 is retracted upward (on the upper tape running surface 12c side). As a result, the subsequent tape stop portion 32a and the tape guide portion The succeeding carrier tape 200 ′ waiting at the succeeding tape waiting position Q3 can pass in the tape feeding direction A between the lower tape running surface 12b of 12d (the lifting tape running surface 50a of the lifting block 50).

  When the sensor 60 shown in FIG. 1 detects the rear end 212 of the preceding carrier tape 200 being fed in the tape feeding direction A by the sprockets 16 and 18, the sprocket 14 starts to rotate, and the feeding of the subsequent carrier tape 200 ′ is performed. Is started.

  In this way, the plurality of carrier tapes 200 are sequentially fed in the tape feeding direction A.

  As described above, according to the present embodiment, a plurality of carrier tapes 200 can be reliably and sequentially fed in the tape feeding direction A without being affected by the thicknesses of the preceding carrier tape 200 and the succeeding carrier tape 200 ′. it can.

  This will be specifically described.

  First, as shown in FIGS. 4A and 4B, at least a part of the leading tape contact portion 34 b of the lock portion 34 of the trailing tape restraining mechanism 30 is not in contact with the leading carrier tape 200. 12d is disposed in a recess 12e formed in the lower tape running surface 12b. Further, as shown in FIG. 3, the preceding tape contact portion 34b of the lock portion 34 can contact the preceding carrier tape 200 moving in the tape feeding direction A on the lower tape running surface 12b and can ride on the upper surface 200a. It is configured. Therefore, the preceding tape contact portion 34b can move with a stroke greater than the thickness of the carrier tape 200. Accordingly, the lock portion 34 can move with a stroke greater than the thickness of the carrier tape 200, and the stopper contact portion 34b is also separated from the engaging portion 32a of the stopper portion 32 with a stroke greater than the thickness of the carrier tape 200. Can do.

  That is, as shown in FIGS. 4B and 4F, the succeeding tape stop portion 32a of the stopper portion 32 is located below the tape guide portion 12d so that the preceding carrier tape 200 and the succeeding carrier tape 200 ′ can pass in the tape feeding direction A. The stopper contact portion 34a of the lock portion 34 has a stroke larger than the thickness of the carrier tape 200 from the engagement portion 32a of the stopper portion 32 when sufficiently separated from the tape running surface 12b (the raising and lowering tape running surface 50a of the lifting block 50). You can leave at.

  When the stopper contact portion 34a of the lock portion 34 is separated from the engagement portion 32b of the stopper portion 32 by a stroke greater than the thickness of the carrier tape 200, the engagement portion 32b of the stopper portion 32 and the engagement portion 32b of FIG. Contact with the stopper contact portion 34a of the lock portion 34 can be released. Thereby, the stopper part 32 freely swings independently without being influenced by the lock part 34.

  Therefore, as shown in FIG. 4C and FIG. 4E, the trailing tape restraining portion 32 a of the stopper portion 32 has a lower tape running surface 12 b (the raising and lowering of the lifting block 50) as shown in FIGS. 4C and 4E. It is possible to come down and contact toward the tape running surface 50a). That is, regardless of the thickness of the preceding carrier tape 200 that is in contact with the preceding tape contact portion 34b of the lock portion 34, the succeeding tape stopping portion 32a of the stopper portion 32 has its own weight, so that the preceding carrier tape 200 or the tape guide The contact with the lower tape running surface 12b of the portion 12d (the lifting tape running surface 50a of the lifting block 50) can be maintained. As a result, even if the subsequent carrier tape 200 ′ has a small thickness, the subsequent tape stop portion 32a can reliably stand by (when the subsequent carrier tape 200 ′ is stopped by the stopper portion 32, the succeeding tape tape 200 ′ has a small thickness. ) Is prevented from passing in the tape feeding direction A below the succeeding tape stopper 32a).

  As described above, the plurality of carrier tapes 200 can be reliably and sequentially fed in the tape feeding direction A without being affected by the thicknesses of the preceding carrier tape 200 and the succeeding carrier tape 200 '.

  Although the present invention has been described with reference to the above-described embodiment, the present invention is not limited to the above-described embodiment.

  For example, in the case of the above-described embodiment, as shown in FIG. 3, the lock portion 34 of the subsequent tape restraining mechanism 30 is a member that swings about the swing center line S <b> 1. Not limited to this.

  For example, FIG. 5 schematically shows a trailing tape restraining mechanism 130 of a component supply device according to another embodiment of the present invention.

  As shown in FIG. 5, the subsequent tape restraining mechanism 130 includes a stopper 132 that can swing around a swing center line S <b> 1 extending in the tape width direction (X-axis direction), and a tape thickness direction of the carrier tape 200. A stopper portion 134 that is movable in the (Z-axis direction) is provided.

  The stopper portion 132 of the subsequent tape stopping mechanism 130 has a free end on the upstream side in the tape feeding direction A and a free end on the downstream side with respect to the swing center line S1, and is provided on the free end side on the upstream side. Further, the succeeding tape stop portion 132a that contacts the front end 210 ′ of the succeeding carrier tape 200 ′ that is superimposed on the preceding carrier tape 200 and moves in the tape feeding direction A, and the engaging portion provided on the free end side on the downstream side. 132b.

  The lock part 134 of the succeeding tape restraining mechanism 130 comes into contact with the engaging part 132b of the stopper part 132 at least from above, so that the carrier tape 200 moves in the tape feeding direction A between the succeeding tape restraining part 132a and the tape running surface 112b. A stopper 134a that retracts and locks the succeeding tape stopper 132a above the tape running surface 112b so that it can pass through, and a tape feed between the succeeding tape restrainer 132a of the retracted stopper 132 and the tape running surface 112b. And a preceding tape contact portion 134b that can run on the upper surface of the preceding carrier tape 200 that has passed in the direction A.

  The preceding tape contact portion 134b of the lock portion 134 of the succeeding tape stopping mechanism 130 is configured with an inclined surface whose downstream side is lower than the upstream side in the tape feeding direction A.

  As shown in FIG. 5 (a), the tape feed direction on the tape running surface 112b is moved to the preceding tape contact portion 134b of the lock portion 134 at least partially entering the recess 112d formed on the tape running surface 112b. When the preceding carrier tape 200 moving to A comes into contact, the lock portion 134 moves upward and the preceding tape contact portion 134b rides on the upper surface of the preceding carrier tape 200. As a result, the lock of the stopper 132 by the lock 134 is released, and as shown in FIG. 5B, the subsequent tape stopper 132a of the stopper 132 descends and contacts the preceding carrier tape 200.

  As described above, the lock portion of the subsequent tape restraining mechanism included in the component supply device according to the embodiment of the present invention can take various forms, contacts the preceding carrier tape, and If it moves with the stroke more than thickness and can ride on the upper surface of a preceding carrier tape, the form will not be ask | required.

  As shown in FIG. 3, in the case of the component supply apparatus 10 of the above-described embodiment, the lower tape running surface 12 b of the tape guide portion 12 d facing the lower surface 200 b of the carrier tape 200 is continuous in the tape feeding direction A. (As long as the lift tape running surface 50a and the lower tape running surface 12b of the raising and lowering block 50, the carrier tape 200 may be substantially continuous so as to be movable in the tape feeding direction A, and is partially discontinuous. However, the embodiment of the present invention is not limited to this.

  For example, as shown in FIG. 6, the carrier tape 200 is guided by arranging a plurality of freely rotatable rollers 250 in the tape feeding direction A around a rotation center line extending in the tape width direction (X-axis direction). You may comprise the tape running surface 312b to do. The carrier tape 200 is fed in the tape feeding direction A on the plurality of rollers 250. In this case, a part of the preceding tape contact part 134 b of the lock part 134 of the succeeding tape stopping mechanism 130 enters between the adjacent rollers 250.

  Furthermore, in the case of the component supply apparatus 10 of the above-described embodiment, as shown in FIG. 4C, when the contact between the stopper contact portion 34a of the lock portion 34 and the engagement portion 32b of the stopper portion 32 is released (the lock portion 34). When the stopper portion 32 is unlocked), the succeeding tape restraining portion 32a of the stopper portion 32 of the succeeding tape restraining mechanism 30 is lowered toward the preceding carrier tape 200 by its own weight. Instead of its own weight, it is also possible to urge the trailing tape stopping portion 32a toward the preceding carrier tape 200 (that is, the lower tape running surface 12b of the tape guide portion 12d) by a biasing member such as a spring. is there.

  The present invention is applicable to any component supply device that supplies components using a carrier tape.
