Tape feeder

This specification relates to a tape feeder that sends carrier tapes to supply parts.

The technique of mass-producing board products by performing board-to-board work on boards with printed wiring is widespread. As a typical example of a board-to-board work machine that performs board-to-board work, there is a component-mounting machine that carries out component-mounting work. Many component mounters are equipped with a tape feeder that feeds carrier tape to supply components. In general, the tape feeder can use a plurality of types of carrier tapes having different shapes and materials. A technical example of this type of tape feeder is disclosed in Patent Document 1.

The tape feeder of Patent Document 1 has a pair of tape support portions that support both ends (two side edges) in the width direction of the carrier tape, a concave groove provided between the tape support portions, and a tape having a concave groove. It is provided with a support surface provided at the insertion side end portion and located at a height higher than the tape support portion. According to this, it is said that it is possible to avoid a state in which one of both ends of the carrier tape falls into the concave groove and the carrier tape can be stably inserted.

International Publication No. 2016/142789

By the way, in the tape feeder of Patent Document 1, the carrier tape bends at a position where it is inserted into the tape support portion from the support surface provided at a high position. Therefore, when the operator inserts the carrier tape, a feeling of resistance is generated, which is not preferable. Further, the tape feeder is required to have good usability regardless of the type of carrier tape.

Therefore, in the present specification, it is an issue to be solved to provide a tape feeder capable of smooth insertion regardless of the type of carrier tape.

Disclosed is a tape feeder comprising a bottom in contact with, and an insertion-side carrier with an inclined guide that contacts the inferior surface of the side edge while gradually separating upward from the bottom as it advances forward from the insertion position. do.

In the tape feeders disclosed herein, the tape transport path includes a supply side transport path with two transport guides and a guide groove, and an insertion side transport path with a bottom and tilted guide. Therefore, when the embossed carrier tape is inserted into the insertion side transport path, the side edge portion rises along the inclined guide, and when advancing to the supply side transport path, the side edge portion changes from the inclined guide to the transport guide. Transfers smoothly, and the cavity smoothly enters the guide groove. Further, other types of carrier tapes other than the embossed carrier tape smoothly transfer from the inclined guide to the transport guide. Therefore, the operator can smoothly insert the carrier tape regardless of the type.

1. 1. Configuration of Carrier Tape (91, 95) First, the configuration of the carrier tape (91, 95) used in the tape feeder 1 of the embodiment will be described with reference to FIGS. 1 and 2. The carrier tape (91, 95) accommodates the component P in each of the plurality of cavities (921, 961), and these components P can be supplied in order. The carrier tape (91, 95) is provided in a form wound around a reel and is drawn out from the reel for use. The carrier tapes (91, 95) are roughly classified into an embossed carrier tape 91 and a constant thickness carrier tape 95.

As shown in FIG. 1, the embossed carrier tape 91 is composed of a base tape 92 and a cover tape 93. The base tape 92 has a plurality of cavity portions 921. The cavity portion 921 is provided at a constant pitch in the tape length direction and is opened upward to accommodate the component P. The base tape 92 also has a portion higher than the lower surface of the cavity portion 921, specifically, a side edge portion 922 extending outward in the tape width direction from the upper edge portion of the cavity portion 921, and a side edge portion 923. The thickness T of the cavity portion 921 is appropriately changed according to the height of the component P to be housed.

One side edge portion 922 is formed wider in the tape width direction than the other side edge portion 923, and a feed hole 924 is formed by drilling. The feed holes 924 are provided at a constant pitch in the tape length direction. The pitch of the feed hole 924 and the pitch of the cavity portion 921 are preferably, but not limited to, one being an integral multiple of the other. The base tape 92 is formed by embossing a flexible tape-shaped material such as resin.

The width dimension of the cover tape 93 in the tape width direction is smaller than that of the base tape 92. The cover tape 93 has side edges on both sides in the width direction adhered to the base tape 92 to cover the cavity portion 921 and prevent the component P from scattering. The cover tape 93 is arranged so as to avoid the feed hole 924. The cover tape 93 is formed, for example, by using a thin and transparent polymer film.

As shown in FIG. 2, the constant-thickness carrier tape 95 is composed of a base tape 96, a bottom tape 97, and a cover tape 98. The base tape 96 is made of a flexible material such as paper or resin, and has a constant thickness. The base tape 96 has a plurality of cavity portions 961. The cavity portion 961 is formed by drilling at a constant pitch in the tape length direction, and accommodates the component P. The position of the cavity 961 in the tape width direction is off the center. The bottom tape 97 is adhered to the lower side of the base tape 96. The width dimension of the bottom tape 97 in the tape width direction substantially matches that of the base tape 96. The bottom tape 97 covers the underside of the cavity 961 and prevents the component P from falling off. The bottom tape 97 is formed by using a thin paper material, a polymer film, or the like, and is transparent or translucent.

The base tape 96 and the bottom tape 97 have side edge portions 962 and side edge portions 963 on both sides separated from the cavity portion 961. One side edge portion 962 is formed wider in the tape width direction than the other side edge portion 963, and the feed hole 964 is formed by drilling. The feed holes 964 are provided at a constant pitch in the tape length direction. Base tape may be used as a general term for base tape 96 and bottom tape 97. The cover tape 98 is formed in the same shape as the cover tape 93 of the embossed carrier tape 91 and is adhered to the base tape 96 to prevent the component P from scattering.

2. 2. Overall Configuration of Tape Feeder 1 of the Embodiment Next, the overall configuration of the tape feeder 1 of the embodiment will be described with reference to FIG. The right side of FIG. 3 corresponds to the front side of the tape feeder 1, and the left side of FIG. 3 corresponds to the rear side of the tape feeder 1. The tape feeder 1 is formed in a flat shape having a small thickness in the width direction (the front and back directions of the paper surface in FIG. 3). The tape feeder 1 is of a method called an autoloading feeder. A plurality of tape feeders 1 are arranged and used in the component mounting machine. The tape feeder 1 is composed of a feeder main body 2, an insertion guide member 3, a tape transfer path 4, a tape transfer mechanism 7, a control unit 8, and the like.

The feeder main body 2 is formed in a flat shape having a length in the front-rear direction, a short length in the vertical direction, and a small thickness in the width direction. The insertion guide member 3 is formed of a member different from the feeder main body 2. The insertion guide member 3 is coupled to the vicinity of the intermediate height on the rear side of the feeder main body 2 by using a mounting plate 31, a mounting screw 32, or the like. By adopting a configuration in which the insertion guide member 3 is not integrated with the feeder main body 2 but is retrofitted as a separate body, the workability of processing and assembling the member is improved, and the manufacturing cost is further reduced.

The tape transport path 4 is provided from the insertion guide member 3 to the upper part of the front side of the feeder main body 2. The tape transport path 4 guides the transport of the embossed carrier tape 91 and the constant thickness carrier tape 95. The tape transport path 4 includes a supply-side transport path 5 on the feeder main body 2 side and an insertion-side transport path 6 on the insertion guide member 3. A supply position 51 for supplying the component P is provided near the front end of the supply-side transport path 5. An insertion position 61 for inserting the carrier tape (91, 95) is provided near the rear end of the insertion-side transport path 6.

The supply-side transport path 5 extends at an angle from approximately the middle height of the rear portion of the feeder main body 2 to near the upper surface of the front portion of the feeder main body 2. Not limited to this, the supply side transport path 5 may extend horizontally. The supply position 51 is located on the upper side near the front end of the supply side transport path 5. A tape peeling mechanism 52 is provided behind the supply position 51 of the supply-side transport path 5. A levitation prevention member 53 is provided on the rear side of the tape peeling mechanism 52 of the supply side transport path 5. The detailed configuration of the tape transport path 4 will be described later separately.

The carrier tapes (91, 95) are conveyed by the tape transfer mechanism 7 and proceed from the rear side of the supply side transfer path 5 toward the supply position 51 on the front side. At this time, the carrier tape (91, 95) is prevented from floating from the supply-side transport path 5 by the floating prevention member 53. Further, in the carrier tape (91, 95), one side edge of the cover tape (93, 98) is peeled off by the tape peeling mechanism 52. Subsequently, the cover tape (93, 98) is folded back on the other side edge, and the component P can be supplied at the supply position 51.

The tape transport mechanism 7 transports the carrier tape (91, 95) inserted at the insertion position 61 to the supply position 51. The tape transport mechanism 7 has a first sprocket 71, a second sprocket 72, and a front servomotor 75 on the lower side of the supply-side transport path 5 near the front of the feeder main body 2. The first sprocket 71 is rotatably supported substantially below the supply position 51. The second sprocket 72 is rotatably supported under the tape peeling mechanism 52. The first sprocket 71 and the second sprocket 72 have the same diameter and are provided with engaging protrusions all around the outer circumference. The engaging protrusions of the first sprocket 71 and the second sprocket 72 penetrate the engaging groove formed in the supply side transport path 5 and engage with the feed hole (924, 964) of the carrier tape (91, 95).

The front servomotor 75 rotationally drives the first sprocket 71 and the second sprocket 72 at equal angular velocities via a gear mechanism of abbreviation. As a result, the tape transport mechanism 7 can transport the carrier tape (91, 95) to the supply position 51. The carrier tape (91, 95) from which the component P is taken out at the supply position 51 is discharged forward.

The tape transport mechanism 7 also has a third sprocket 73, a fourth sprocket 74, and a rear servomotor 76 on the lower side of the supply side transport path 5 near the rear of the feeder main body 2. The third sprocket 73 and the fourth sprocket 74 are rotatably supported under the supply side transport path 5. The fourth sprocket 74 is located behind the third sprocket 73. The third sprocket 73 and the fourth sprocket 74 have the same diameter. Engagement protrusions are provided on the entire circumference of the outer circumference of the third sprocket 73. Engagement protrusions are discretely provided on the outer periphery of the fourth sprocket 74. For example, the fourth sprocket 74 has two engaging protrusions that are 180 ° apart. Therefore, the number of engaging protrusions on the fourth sprocket 74 is smaller than that on the third sprocket 73. The engaging protrusions of the third sprocket 73 and the fourth sprocket 74 penetrate the engaging groove formed in the supply side transport path 5 and engage with the feed hole (924, 964) of the carrier tape (91, 95).

The rear servomotor 76 rotationally drives the third sprocket 73 and the fourth sprocket 74 via a gear mechanism of abbreviation. As a result, the tape transport mechanism 7 can transport the carrier tape (91, 95) to the front side along the supply side transport path 5. The fourth sprocket 74 and the rear servomotor 76 correspond to a feeding mechanism provided near the rear end of the supply side transport path 5 to feed carrier tapes (91, 95).

Further, the next tape holding portion 77 is provided on the upper side of the supply-side transport path 5 near the rear of the feeder main body 2. The next tape holding unit 77 allows the insertion of the second carrier tape (91, 95) while the first carrier tape (91, 95) is being conveyed to the supply position 51. Further, the next tape holding unit 77 holds the tip of the second carrier tape (91, 95) at the standby position 7B (described later). The next tape holding portion 77 is composed of a tape holding member 78, an operating lever 79, a stopper member 7A, and the like.

The tape holding member 78 is arranged on the upper side of the supply side transport path 5 on the rear side of the fourth sprocket 74. The tape holding member 78 is a member that is long in the front-rear direction, and the lower portion on the rear side is cut out in a tapered shape to facilitate the insertion of the carrier tape (91, 95) (see FIG. 4). The tape holding member 78 is brought into contact with and separated from the supply-side transport path 5, and is normally pressed downward by a spring of reference numeral. The tape holding member 78 holds the inserted first carrier tape (91, 95) between the supply side transport path 5 and restricts the insertion of the second carrier tape (91, 95). ..

The front end of the operating lever 79 is swingably supported by the feeder body 2. The rear end of the operation lever 79 projects to the rear of the feeder main body 2 and can be raised by the operator. The operating lever 79 raises the tape holding member 78 against the spring when the rear end is raised. According to this ascending operation, the operator inserts the tip of the second carrier tape (91, 95) to the lower side of the tape holding member 78, and the operator inserts the upper side of the first carrier tape (91, 95) in use. Can be layered on.

The stopper member 7A is provided at a position on the front side of the tape holding member 78 and the fourth sprocket 74. The stopper member 7A regulates the tip of the inserted second carrier tape (91, 95) and causes the stopper member 7A to stand by at the standby position 7B in the supply-side transport path 5. The standby position 7B is set on the front side of the position where the engaging projection of the fourth sprocket 74 penetrates the supply side transport path 5. The stopper member 7A releases the restriction on the tip of the second carrier tape (91, 95) after the rear end of the first carrier tape (91, 95) has passed through the fourth sprocket 74.

As a result, the feed hole (924, 964) near the tip of the second carrier tape (91, 95) engages with a small number of engaging protrusions of the fourth sprocket 74 and is conveyed forward at a low speed. When the tip of the second carrier tape (91, 95) reaches the third sprocket 73, the second carrier tape (91, 95) is conveyed forward at high speed by the third sprocket 73. Finally, the second carrier tape (91, 95) is automatically loaded up to the supply position 51 by the cooperation of the third sprocket 73, the second sprocket 72, and the first sprocket 71. The applicant discloses a detailed configuration example of the tape transport mechanism 7 in International Publication No. 2016/098235.

The control unit 8 is provided on the rear side of the front servomotor 75 of the feeder main body 2, and is not limited to this, and may be provided at another position of the feeder main body 2. The control unit 8 is communicated and connected to the upper control unit of the component mounting machine. The control unit 8 controls the supply of the component P at the supply position 51 by controlling the tape transfer mechanism 7 according to a command from the upper control unit.

Further, the control unit 8 acquires a detection signal from the sensor shown in the figure that detects the end of use of the first carrier tape (91, 95). Based on this detection signal, the control unit 8 waits for the tip of the second carrier tape (91, 95) after the rear end of the first carrier tape (91, 95) has passed through the fourth sprocket 74. The tape transfer mechanism 7 is controlled so as to automatically transfer from 7B to the supply position 51. That is, the control unit 8 also serves as an automatic loading control unit.

3. 3. Detailed Configuration of Tape Transport Path 4 Next, the detailed configuration of the tape transport path 4 will be described with reference to FIG. As described above, the tape transport path 4 includes the supply side transport path 5 and the insertion side transport path 6. In FIG. 4, a part of the side wall material on the front side forming the supply side transport path 5 and the insertion side transport path 6 is omitted.

The supply side transport path 5 has two transport guides (55, 56) and a guide groove 58. The two transport guides (55, 56) are formed by a portion extending in parallel in the anteroposterior direction while being separated, and the upper surface of the portion serves as a guide. Tapered chamfered portions 57 are provided at the rear ends of the two transport guides (55, 56) to facilitate transfer of the carrier tape (91, 95). The space between the two transport guides (55, 56) is the guide groove 58. The groove width dimension of the guide groove 58 is set to be slightly larger than the outer shape of the cavity portion 921 of the embossed carrier tape 91.

One transport guide 55 contacts and supports the lower surface of the wide side edge portion 922 having the feed hole 924 of the inserted embossed carrier tape 91. The other transport guide 56 contacts and supports the lower surface of the narrow side edge portion 923 of the embossed carrier tape 91. When the side edge portion 922 and the side edge portion 923 are supported, the cavity portion 921 automatically enters the guide groove 58. On the other hand, the constant-thickness carrier tape 95 is bridged and supported by two transport guides (55, 56), and has no portion to enter the guide groove 58.

The insertion side transport path 6 is arranged behind the supply side transport path 5. If the insertion-side transport path 6 is omitted, the carrier tape (91, 95) may be inserted into the guide groove 58 while standing upright in the width direction, which is not preferable. The insertion side transport path 6 has a bottom portion 62 and an inclined guide 63. The bottom portion 62 is formed by most of the upper surface of the insertion guide member 3.

The inclined guide 63 is formed on the upper side of one of the two side edges in the width direction of the bottom portion 62 (the side edge on the back side in FIG. 4), and extends in the front-rear direction. The upper surface of the inclined guide 63 serves as a guide. The tilt guide 63 is tilted with respect to the bottom 62 so as to gradually move upward from the bottom 62 as it advances forward from the insertion position 61. The height H from the bottom portion 62 at the front end of the tilt guide 63 is set to be larger than the thickness T of the largest cavity portion 921 of the embossed carrier tape 91.

The insertion side transport path 6 further has two side wall members 64 and a levitation suppressing member 66. The two side wall members 64 are provided so as to stand up from two side edges in the width direction of the bottom portion 62. A tapered chamfered portion 65 is provided inside the two side wall members 64 so as to face each other, facilitating the insertion of the carrier tape (91, 95). In FIG. 4, the side wall material on the front side is not shown, and the side wall material 64 on the back side is in contact with the outside of the inclined guide 63. The buoyancy inhibitor 66 is bridged over the upper edges of the two side wall members 64. A tapered chamfered portion 67 is provided on the lower surface of the rear end of the levitation suppressing member 66, facilitating the insertion of the carrier tape (91, 95). A bottom 62, two side wall members 64, and a buoyancy inhibitor 66 form a rectangular insertion slot in front of the insertion position 61.

The carrier tape (91, 95) is inserted forward from the insertion position 61 via the insertion slot. At this time, the two side wall members 64 suppress the swing of the carrier tape (91, 95) in the tape width direction. Further, the levitation suppressing material 66 suppresses the carrier tape (91, 95) from levitation from the bottom portion 62 and the inclined guide 63. Further, the inclined guide 63 contacts the lower surface of the side edge portion 922 on the wide side of the embossed carrier tape 91 and the lower surface of the side edge portion 962 on the wide side of the constant thickness carrier tape 95, and guides them diagonally forward and upward. do.

Therefore, when the embossed carrier tape 91 is inserted, the bottom portion 62 contacts and supports the lower surface of the cavity portion 921 up to a certain position in the middle of the insertion side transport path 6, and the inclined guide 63 supports the lower surface of the cavity portion 921. Separated from the lower surface of the portion 922. Then, in front of the insertion-side transport path 6 past a certain position, conversely, the bottom portion 62 is separated from the lower surface of the cavity portion 921, and the inclined guide 63 is in contact with the lower surface of the side edge portion 922, so that the embossed carrier tape is used. Supports the whole of 91.

Further, when the constant-thickness carrier tape 95 is inserted, the bottom portion 62 contacts the lower surface of the constant-thickness carrier tape 95 to support the constant-thickness carrier tape 95 in a limited range on the front side of the insertion position 61. Then, in the range where the inclined guide 63 exists, the inclined guide 63 comes into contact with the lower surface of the side edge portion 962 to support the entire constant-thickness carrier tape 95.

Here, the inclined guide 63 of the insertion side transport path 6 and the two transport guides (55, 56) of the supply side transport path 5 are arranged on one plane. That is, the tilt guide 63 and the transport guides (55, 56) have the same tilt angle. On the other hand, the tilt angle of the bottom portion 62 is smaller than the tilt angle of the tilt guide 63.

4. Action of Tape Feeder 1 of the Embodiment Next, the action when the operator inserts the carrier tape (91, 95) into the tape feeder 1 will be described with reference to FIGS. 5 and 6. In addition, it will be described in comparison with the configuration of the comparative example of FIGS. 7 and 8.

In FIG. 5, the embossed carrier tape 91 is inserted from the insertion position 61 toward the front. The embossed carrier tape 91 advances while the side edge portion 922 on the wide side is in contact with and supported by the inclined guide 63. At this time, since the side edge portion 922 on the wide side is supported, the embossed carrier tape 91 can advance with almost no inclination in the tape width direction. In contrast, the configuration in which the tilt guide 63 contacts the lower surface of the side edge portion 923 on the narrow side cannot be adopted because the embossed carrier tape 91 tends to tilt in the tape width direction.

The embossed carrier tape 91 reaches the boundary position between the insertion side transport path 6 and the supply side transport path 5 with the cavity portion 921 floating from the bottom portion 62. Here, since the tilt guide 63 and the transport guides (55, 56) are arranged on one plane, the side edge portion 922 smoothly moves from the tilt guide 63 to the transport guide 55 without changing the traveling direction. You can transfer. Further, the cavity portion 921 can smoothly enter the guide groove 58 located in the front without changing the traveling direction. Therefore, the operator can smoothly insert the embossed carrier tape 91.

Further, in FIG. 6, the constant thickness carrier tape 95 is inserted from the insertion position 61 toward the front. The constant-thickness carrier tape 95 reaches the boundary position between the insertion-side transport path 6 and the supply-side transport path 5 in a state where the wide side edge portion 962 is in contact with and supported by the inclined guide 63. Here, since the tilt guide 63 and the transport guide (55, 56) are arranged on one plane, the constant-thickness carrier tape 95 can be transferred from the tilt guide 63 to the transport guide (55,) without changing the traveling direction. You can smoothly transfer to 56). Therefore, the operator can smoothly insert the constant-thickness carrier tape 95.

On the other hand, in the first comparative example shown in FIG. 7, the insertion side transport path 6X does not include the inclined guide 63. Further, the configuration of the supply-side transport path 5 is the same as that of the embodiment. The bottom portion 62X of the insertion-side transport path 6X is arranged on the same plane as the transport guides (55, 56). Therefore, the constant-thickness carrier tape 95 can be smoothly transferred from the bottom portion 62X to the transport guides (55, 56).

However, when the embossed carrier tape 91 is transferred from the bottom portion 62X to the transport guide (55, 56), the embossed carrier tape 91 sinks by the thickness T of the cavity portion 921, and the side edge portion 922 comes into contact with the transport guide 55, and the side edge portion 91 comes into contact with the transport guide 55. The portion 923 comes into contact with the transport guide 56, and the cavity portion 921 enters the guide groove 58. In this way, the traveling direction of the embossed carrier tape 91 changes downward. Further, the downward change in the traveling direction of the embossed carrier tape 91 collides with the tape holding member 78 and is forcibly performed. Therefore, when the operator inserts the embossed carrier tape 91, a feeling of resistance is generated, which is not preferable.

Further, in the second comparative example shown in FIG. 8, the insertion side transport path 6Y does not include the inclined guide 63. Further, the configuration of the supply-side transport path 5 is the same as that of the embodiment. The front end of the bottom portion 62Y of the insertion-side transport path 6Y is arranged lower than the transport guide (55, 56) by the thickness T of the cavity portion 921. Therefore, in the embossed carrier tape 91, the side edge portion 922 and the side edge portion 923 traveling higher than the bottom portion 62Y smoothly transfer to the transport guides (55, 56), and the cavity portion 921 smoothly enters the guide groove 58. ..

However, since the constant-thickness carrier tape 95 advances along the bottom portion 62Y arranged low, it is necessary to ride on the carrier tape while colliding with the transport guides (55, 56), and the traveling direction changes upward. Further, the upward traveling direction of the constant-thickness carrier tape 95 is forcibly changed to the forward direction by the tape holding member 78. Therefore, when the operator inserts the constant-thickness carrier tape 95, a feeling of resistance is generated, which is not preferable. Even in the embossed carrier tape 91 having a small thickness T of the cavity portion 921, a feeling of resistance is generated by the same action.

Unlike the first comparative example and the second comparative example, in the tape feeder 1 of the embodiment, the tape transport path 4 includes the insertion side transport path 6 having the bottom portion 62 and the inclined guide 63. Therefore, when the embossed carrier tape 91 is inserted into the insertion-side transport path 6, the side edge portion 922 rises along the inclined guide 63, and when the embossed carrier tape 91 advances to the supply-side transport path 5, the side edge portion 922 rises. The inclined guide 63 smoothly transfers to the transport guide 55, and the cavity portion 921 smoothly enters the guide groove 58. Further, the constant-thickness carrier tape 95 smoothly transfers from the inclined guide 63 to the transport guides (55, 56). Therefore, the operator can smoothly insert the carrier tape regardless of the type.

5. Application and Modification of the Embodiment Although the tilt guide 63 is one in the embodiment, it may be provided on both side edges of the bottom portion 62 in the width direction to be two. Further, although the tape feeder 1 of the embodiment is an auto-loading feeder, it may be a general tape feeder for performing splicing work. However, in the tape feeder 1 of the embodiment, the distance between the insertion position 61 and the fourth sprocket 74 is larger than that of a general tape feeder due to the configuration restriction including the next tape holding portion 77. Therefore, in the tape feeder 1 of the embodiment, the insertion length for inserting the carrier tape (91, 95) becomes large, and the effect of smooth insertion becomes remarkable. This embodiment can be applied and modified in various ways.
