Feeder
[0006]
[0001] This specification relates to a feeder.
[0002] Conventionally, a component mounter that detachably mounts a feeder for feeding and transporting a carrier tape is known (see, for example, Patent Document 1). This feeder has a reel holder that rotatably holds a reel around which a carrier tape is wound, a tape feeding mechanism that feeds the carrier tape drawn from the reel held by the reel holder to a component supply position, and a peeling mechanism that peels a cover tape from the carrier tape to expose the components in the carrier tape. In this feeder, the reel holder, the tape feeding mechanism, and the peeling mechanism are housed in a case formed in a box shape.
[0003] Further, the above-mentioned component mounter has a plurality of slots that detachably hold feeders, respectively, and a drive device including a motor provided for each slot and applying a driving force to the carrier tape in the feeder held in the slot. The component mounter drives the drive device corresponding to the slot in a state where the feeder is held in the slot, thereby feeding and transporting the carrier tape from the feeder held in the slot, picking up components from the cavity of the carrier tape, and mounting them on a substrate.
[0004] Japanese Patent Application Laid-Open No. 2019-075445
[0005] In the component mounter described in Patent Document 1 mentioned above, since a drive device for applying a driving force to the carrier tape in the feeder is provided, it is not necessary to mount a drive device for applying a driving force to the carrier tape on the feeder itself. Therefore, it is possible to simplify the feeder. However, in this system, it is necessary to provide a drive device for applying a driving force to the carrier tape for each component mounter and further for each slot, so the cost of the component mounter increases, and inconveniences such as the entire component mounter cannot be operated during the repair when a failure occurs in one of the plurality of drive devices may occur.
[0006] Therefore, instead of a component mounting machine, it is conceivable to equip the feeder with a drive device that provides driving force to the carrier tape. With a system in which a drive device is provided for each feeder, it becomes unnecessary to provide a drive device for the component mounting machine, thus making it possible to suppress inconveniences such as increased costs for the component mounting machine.
[0007] Incidentally, in circuit board production equipment where component mounting machines attach various types of components to circuit boards, it is necessary to prepare in advance multiple types of carrier tapes with different tape widths and tape reels to store those carrier tapes. Furthermore, even if there are components that are used infrequently, it is necessary to prepare a feeder that corresponds to the carrier tape and tape reel that stores that carrier tape for those components. However, if it is necessary to prepare the entire feeder, including the drive unit and reel holder, as surplus equipment even for feeders that store infrequently used components, the equipment costs may become excessive or the space required for feeder storage may become excessively large.
[0008] This specification aims to provide a feeder that can reduce equipment costs in feeder operation and save storage space.
[0009] This specification discloses a feeder comprising: a feeder body having a feed drive source that generates a feed drive force for feeding and transporting a carrier tape; a feed sprocket that applies the feed drive force generated by the feed drive source to the carrier tape; a holder portion having a reel holder that rotatably holds a reel around which the carrier tape is wound; and a mounting portion that detachably attaches the holder portion to the feeder body, wherein the mounting portion has a first locking portion that attaches the feeder body and the holder portion in a first positional relationship; and a second locking portion that attaches the feeder body and the holder portion in a second positional relationship different from the first positional relationship.
[0010] Furthermore, this specification discloses a feeder comprising: a feeder body having a feed drive source that generates a feed drive force for feeding and transporting a carrier tape; a winding drive source that generates a winding drive force for winding up a cover tape peeled off the base tape of the carrier tape; a feed sprocket that applies the feed drive force generated by the feed drive source to the carrier tape; and a winding gear that applies the winding drive force generated by the winding drive source to the cover tape; a holder portion having a reel holder that rotatably holds a reel around which the carrier tape is wound; a collection box for collecting the cover tape; and a detachable portion for attaching and detaching the collection box to the reel holder; and a mounting portion for detachably attaching the holder portion to the feeder body, wherein the mounting portion has a reel holder mounting portion that allows the reel holder to be attached to the feeder body when the collection box is attached to the reel holder by the detachable portion and when the collection box is not attached to the reel holder.
[0011] According to this disclosure, it is possible to reduce equipment costs for feeder operation and save storage space.
[0012] Furthermore, this specification also discloses the technical idea of changing "the feeder described in claim 1" to "the feeder described in claim 1 or 2" in claim 3 of the original application, the technical idea of changing "the feeder described in claim 1" to "the feeder described in any one of claims 1 to 3" in claim 4 of the original application, and the technical idea of changing "the feeder described in claim 7" to "the feeder described in claim 7 or 8" in claim 9 of the original application.

[0014] Hereinafter, embodiments of the feeder according to this disclosure will be described with reference to Figures 1 to 17.
[0015] 1. Configuration of the component mounting machine for setting the feeder - The feeder 20 according to this embodiment is a device that supplies components to be mounted on a circuit board to the component picking position S (see Figures 4 to 9). The feeder 20 is detachably incorporated into the component mounting machine 1.
[0016] The component mounting machine 1 is installed in a circuit board production line that produces circuit boards by mounting components onto them. The component mounting machine 1 picks up or grasps components supplied to the component picking position S by the feeder 20, transfers them to the circuit board, and mounts them.
[0017] The component mounting machine 1 includes a feeder set stand 10, as shown in Figures 1 and 2. The feeder set stand 10 is a box-shaped base for setting multiple feeders 20. The feeder set stand 10 has slots 11, as shown in Figures 1 and 2. The slots 11 are gaps into which the feeders 20 can be inserted one by one in a detachable manner. The slots 11 are formed in a shape that allows the feeders 20 to be supported in a vertical position. Multiple slots 11 are arranged side by side on the feeder set stand 10. The number of slots 11 on the feeder set stand 10 is, for example, 20.
[0018] As shown in Figures 1 and 2, the feeder set stand 10 has a clamp groove 12 into which the feeder 20 fits, and a connector 13 to which the power lines and signal lines of the feeder 20 are connected. The clamp groove 12 and the connector 13 are provided corresponding to each slot 11. The clamp groove 12 has an upper groove 12u provided at the top of the space that accommodates the feeder 20, and a lower groove 12d provided at the bottom of that space. The upper groove 12u is formed in a T-shape in cross-section so that a protrusion provided on the upper part of the feeder 20 can be inserted, as shown in Figure 16, for example. The lower groove 12d is formed so that the lower part of the feeder 20 can be clamped. The connector 13 is provided on the side wall on the front side of the feeder set stand 10, which is close to the substrate. Positioning protrusions or positioning holes for positioning the feeder 20 within the slot 11 may be provided on this side wall.
[0019] Furthermore, as described later, the feeder 20 can have its assembly configuration switched, and the feeder set stand 10 of the component mounting machine 1 is provided in types corresponding to the assembly configuration of the feeder 20. The feeder 20 can be set on the feeder set stand 10 in an assembly configuration corresponding to the type of feeder set stand 10.
[0020] The feeder 20 is capable of transporting the carrier tape 2. The components supplied by the feeder 20 are electronic components such as transistors, diodes, and resistors that make up electronic circuits. These components include, for example, tiny components such as 0201 size (0.2 mm x 0.1 mm) and large components such as capacitors.
[0021] 2. Carrier Tape and Tape Reel Configuration The carrier tape 2 is formed in a long shape. The carrier tape 2 generally has a tape width predetermined as a standard, such as 4 mm, 8 mm, 12 mm, 16 mm, or 24 mm. As shown in Figure 3, the carrier tape 2 has a base tape 2a and a cover tape 2b. The base tape 2a has component storage sections that store components arranged at predetermined intervals along the length of the tape. The cover tape 2b is a film-like member that covers the component removal opening of the base tape 2a.
[0022] When the cover tape 2b is attached to the base tape 2a, the components are contained within the component storage section of the base tape 2a, and when the cover tape 2b is peeled off the base tape 2a, the components are exposed from the component storage section and can be removed to the outside. The carrier tape 2 may be an embossed tape in which the component storage section of the base tape 2a protrudes downward, or it may be a paper tape with groove-shaped component storage sections on its surface. The carrier tape 2 is wound around a reel 3.
[0023] The reel 3 is formed in a disc shape. The reel 3 is made of, for example, resin or corrugated cardboard. As shown in Figure 3, the reel 3 has a holding hole 3a and a reel flange 3b. The holding hole 3a is a through hole that penetrates in the direction of the rotation axis and is necessary for holding the reel 3 on the feeder 20. The reel flange 3b is a disc-shaped part that spreads out from the holding hole 3a. The holding hole 3a is positioned on the axis of the reel flange 3b and extends in the reel width direction (hereinafter referred to as the reel width direction Y as appropriate), which coincides with the tape width direction Y of the carrier tape 2 wound around the reel 3.
[0024] The reel flanges 3b are provided in pairs, separated in the reel width direction Y. The pair of reel flanges 3b are arranged to sandwich the carrier tape 2 to be wound around. The pair of reel flanges 3b are separated in the reel width direction Y such that a gap greater than or equal to the tape width of the carrier tape 2 to be wound around is formed. Generally, the reel 3 used is one in which the distance between the pair of reel flanges 3b in the reel width direction Y (i.e., the reel width) is predetermined by a standard (e.g., JIS standard), but non-standard reels may also be used.
[0025] 3. Feeder Configuration The feeder 20 is a tape feeder capable of housing the reel 3. The feeder 20 can be configured as either a manually replaceable general-purpose feeder that discharges the cover tape 2b peeled off the base tape 2a of the carrier tape 2 to the outside of the feeder, or an automatically replaceable cassette-type feeder that incorporates a collection box for collecting the cover tape 2b peeled off the base tape 2a of the carrier tape 2.
[0026] Hereinafter, the general feeder 20 will be simply referred to as feeder 20, a feeder 20 with a standard assembly configuration will be referred to as A-feeder 20A, and a feeder 20 with a cassette-type assembly configuration will be referred to as B-feeder 20B. Furthermore, a feeder set stand 10 corresponding to A-feeder 20A will be referred to as A-feeder set stand 10A (see Figure 1), and a feeder set stand 10 corresponding to B-feeder 20B will be referred to as B-feeder set stand 10B (see Figure 2).
[0027] As shown in Figures 4 to 9, the feeder 20 comprises a feeder body 30, a holder 40, and a mounting part 50. Figures 4, 5, and 6 show the A feeder 20A, and Figures 7, 8, and 9 show the B feeder 20B.
[0028] The feeder body 30 is a main body component that forms the housing of the feeder 20, including the skeletal portion and the mounting portion that is attached to the slot 11 of the parts mounting machine 1. The feeder body 30 is detachable from the slot 11 of the feeder set stand 10 of the parts mounting machine 1 and is formed in a flat shape. The feeder body 30 is located on the upper part of the feeder 20. The above-mentioned parts sampling position S is provided on the upper part of the front end of the feeder body 30.
[0029] The feeder body 30 includes a feed drive source 31 and a feed sprocket 32. The feed drive source 31 and the feed sprocket 32 constitute a tape transport mechanism that feeds and transports the carrier tape 2. The feed drive source 31 and the feed sprocket 32 are located at the upper end of the feeder body 30 and at the downstream end (i.e., the front end) in the tape transport direction X. The feed drive source 31 is a drive source that generates the feed drive force to feed and transport the carrier tape 2. The feed drive source 31 is an electric motor or the like that is rotationally driven by power supply. The feed sprocket 32 is a rotating body that transmits the feed drive force generated by the feed drive source 31 to the carrier tape 2. The feed drive source 31 and the feed sprocket 32 may mesh with each other via one or more gears.
[0030] The feeder body 30 has a transport path 33. The transport path 33 is a passage that transports and supports the carrier tape 2 pulled out from the reel 3. The transport path 33 is in contact with the lower surface of the carrier tape 2 and supports the carrier tape 2 from below. The transport path 33 extends along the tape transport direction X. The transport path 33 supports the carrier tape 2 with its upper surface facing upward or diagonally upward, and with the inner surfaces of its vertical walls facing to the sides on both sides in the tape width direction Y.
[0031] The external teeth, which are engaging projections at the upper end of the feed sprocket 32 described above, protrude above the transport path 33. These external teeth engage with the feed holes of the carrier tape 2, which is pulled out from the reel 3 and transported on the transport path 33. When the feed drive source 31 generates a feed drive force in this engaged state, the feed sprocket 32 rotates in the forward direction due to the feed drive force, and the carrier tape 2 is fed and transported in the tape transport direction X.
[0032] The feeder body 30 has a tape guide 34. The tape guide 34 is a guide that guides the carrier tape 2 being transported on the transport path 33. The tape guide 34 is positioned above the feed sprocket 32 and faces the feed sprocket 32 in the vertical direction Z across the transport path 33. The carrier tape 2 is transported in the tape transport direction X while being sandwiched between the tape guide 34 and the transport path 33. On the downstream side of the tape transport direction X of the tape guide 34, there is an exposed portion (not shown) that is exposed upward and serves as a part picking position S.
[0033] The tape guide 34 is detachably attached to the front and upper end of the feeder body 30, which is the downstream end in the tape transport direction X. The tape guide 34 may be replaceable with respect to the feeder body 30 depending on the type of carrier tape 2 to be transported. The tape guide 34 is formed in a U-shape in cross-section so that it can contact the upper and side surfaces of the carrier tape 2. When the carrier tape 2 is transported in the tape transport direction X, it is guided in contact with the upper and side walls of the tape guide 34.
[0034] The tape guide 34 has a folded portion (not shown). The folded portion is the part where the cover tape 2b, which has been peeled off from the base tape 2a of the carrier tape 2 pulled out from the reel 3, is folded back toward the upstream side in the tape transport direction X. The folded portion is provided on the upstream side of the tape guide 34 in the tape transport direction X.
[0035] The holder portion 40 is a component capable of holding the reel 3. The holder portion 40 is constructed separately from the feeder body portion 30 and is detachable from the feeder body portion 30. The holder portion 40 is formed in a flat shape and is attached to the feeder body portion 30 by a mounting portion 50. The holder portion 40 is located at the bottom of the feeder 20. The holder portion 40 includes a reel holder 41, a collection box 42, and a detachable portion 43.
[0036] The reel holder 41 is a member that rotatably holds the reel 3 around which the carrier tape 2 is wound. The reel holder 41 is formed in a substantially angular shape (for example, a square shape) in a side view, as shown in Figure 5, for example. There may be multiple types of reel holders 41, depending on the type of reel 3 and the width of the reel in the width direction Y. In this case, each reel holder 41 only needs to have a common structure in the part that is attached to the feeder body 30.
[0037] The reel holder 41 is configured to allow a single reel 3 to be attached and detached. The reel holder 41 has a reel holding shaft 41a that rotatably supports the reel 3. A reel storage space for housing the reel 3 is formed around the reel holding shaft 41a.
[0038] The reel holder 41 has a reel cover 41b. The reel cover 41b is a plate-shaped member that covers part or all of the reel storage space of the reel holder 41 from the outside in the reel width direction Y. The reel cover 41b has the function of holding the reel 3 stored in the reel storage space. The reel cover 41b is openable and closable, and is normally closed, but can be opened for replacement or maintenance of the reel 3.
[0039] The collection box 42 is a component for collecting the cover tape 2b that has been peeled off from the base tape 2a of the carrier tape 2. The collection box 42 is constructed separately from the reel holder 41 and is detachable from the reel holder 41. In a side view, the collection box 42 is formed in a roughly angular shape (for example, a square shape). The collection box 42 has a cover storage space for collecting and storing the cover tape 2b. The reel holder 41 is located on the rear side of the holder portion 40, which is the upstream side in the tape transport direction X, and the collection box 42 is located on the front side, which is the downstream side in the tape transport direction X. The reel holder 41 and the collection box 42 are detached from each other by a detachable portion 43.
[0040] The feeder body 30 includes a winding drive source 35 and a winding gear 36. The winding drive source 35 and the winding gear 36 form a cover tape retrieval mechanism that applies winding drive force to wind up the cover tape 2b peeled off from the base tape 2a. The winding drive source 35 and the winding gear 36 are positioned midway in the tape transport direction X of the feeder body 30, and are located upstream of the feed drive source 31 and the feed sprocket 32 in the tape transport direction X. The winding drive source 35 is an electric motor or the like that generates the winding drive force to be applied to the cover tape 2b peeled off from the base tape 2a. The winding gear 36 is a disc-shaped member that applies the winding drive force generated by the winding drive source 35 to the cover tape 2b.
[0041] The cover tape 2b, peeled off from the base tape 2a, is folded back at the folded portion of the tape guide 34 of the feeder body 30 and guided to a predetermined recovery path in the feeder body 30. Then, the cover tape 2b is guided to the winding gear 36 while tension is applied from the tensioner, and is sequentially peeled off from the base tape 2a by the winding drive force generated by the winding drive source 35 and recovered in the recovery box 42 or discharged outside the feeder 20.
[0042] The collection box 42 is positioned below the winding drive source 35 and the winding gear 36. The tape inlet of the collection box 42 is exposed upwards below the winding drive source 35 and the winding gear 36. After the cover tape 2b is peeled off from the base tape 2a, it is driven by the winding drive source 35, passes through the winding gear 36, and is collected in the collection box 42.
[0043] The attachment / detachment part 43 is a part for attaching / detaching the collection box 42 to / from the reel holder 41. The attachment / detachment part 43 has a rail running part 43a provided on the reel holder 41 and a rail 43b provided on the collection box 42. The rail running part 43a is provided at the lower end of the reel holder 41. The rail 43b is provided at the lower end of the collection box 42 and is formed to extend in a rod shape upstream in the tape conveyance direction X from the lower end part of the collection box 42. The rail running part 43a and the rail 43b are formed in a cross-sectional concavo-convex shape (for example, T-shaped) that fits into each other. The reel holder 41 and the collection box 42 are attached / detached from each other by relatively moving along the rail 43b in the tape conveyance direction X in a state where the rail running part 43a is fitted into the rail 43b. The reel holder 41 and the collection box 42 are attached and fixed in a state where the end faces in the tape conveyance direction X face or contact each other.
[0044] The attachment part 50 is a part for detachably attaching the holder part 40 to the feeder main body part 30. The feeder main body part 30 and the holder part 40 can be positioned and attached to each other in a first positional relationship, and can also be positioned and attached to each other in a second positional relationship. The first positional relationship corresponds to the A feeder 20A, and only the reel holder 41 of the holder part 40 is attached to the feeder main body part 30. The second positional relationship corresponds to the B feeder 20B, and both the reel holder 41 and the collection box 42 of the holder part 40 are attached to the feeder main body part 30.

The feeder main body 30 and the collection box 42 are then mounted and fixed in a predetermined positional relationship in which relative movement in the tape transport direction X is restricted.
[0054] The first locking portion 51 described above engages the second engaging portion 53b on the main body side and the first engaging portion 54a on the holder side by fastening a screw 55 between the holes when the axis of the hole in the second engaging portion 53b on the main body side and the axis of the hole in the first engaging portion 54a on the holder side are aligned, thereby attaching the feeder main body 30 and the reel holder 41 of the holder portion 40 in the first positional relationship (see Figures 4 to 6).
[0055] Furthermore, the second locking portion 52 is fastened with screws 55 between the holes, such that the axis of the hole in the first engaging portion 53a on the main body side coincides with the axis of the hole in the first engaging portion 54a on the holder side, and the axis of the hole in the second engaging portion 53b on the main body side coincides with the axis of the hole in the second engaging portion 54b on the holder side, thereby engaging the first engaging portion 53a on the main body side with the first engaging portion 54a on the holder side, engaging the second engaging portion 53b on the main body side with the second engaging portion 54b on the holder side, and engaging the third engaging portion 53c on the main body side with the third engaging portion 54c on the holder side, thereby attaching the feeder main body 30 and the holder portion 40 (specifically, the reel holder 41 and the collection box 42) in a second positional relationship (see Figures 7 to 9).
[0056] The first engaging portion 53a on the main body side, the second engaging portion 53b on the main body side, the first engaging portion 54a on the holder side, and the second engaging portion 54b on the holder side form a reel holder mounting portion for attaching the reel holder 41 to the feeder main body 30 when the recovery box 42 is attached to the reel holder 41 by the attachment / detachment portion 43 and when the recovery box 42 is not attached to the reel holder 41. The third engaging portion 53c on the main body side and the third engaging portion 54c on the holder side form a recovery box mounting portion for attaching the recovery box 42 to the feeder main body 30 when the recovery box 42 is attached to the reel holder 41 by the attachment / detachment portion 43.
[0057] Furthermore, the first locking portion 51 and the second locking portion 52 may include a spring that biases the holder portion 40 toward the release side relative to the feeder body portion 30 in the above-described positional relationship, a hook portion that hooks the holder portion 40 onto the feeder body portion 30 against the biasing force of the spring and restricts the movement of the holder portion 40 toward the release side, and a lever portion that operates the hook portion.
[0058] The feeder body 30 includes a first tape introduction section 37 and a second tape introduction section 38.
[0059] The first tape introduction section 37 is the part in the A feeder 20A that guides the carrier tape 2 of the reel 3 to the parts picking position S within the feeder body 30. That is, the first tape introduction section 37 guides the carrier tape 2 wound around the reel 3, which is held in the reel holder 41, to the parts picking position S when the feeder body 30 and the holder section 40 are in a first positional relationship by the first locking section 51.
[0060] The first tape introduction section 37 has a first introduction port 37a and a first introduction passage 37b. The first introduction port 37a is an opening that opens to the outside of the feeder body 30. The first introduction port 37a is the entrance through which the carrier tape 2, pulled out from the reel 3 in the reel holder 41, passes when it is introduced into the feeder body 30. The first introduction passage 37b extends from the first introduction port 37a toward the parts picking position S as a transport path 33, and is the passage through which the carrier tape 2 that has passed through the first introduction port 37a flows.
[0061] The second tape introduction section 38 is the part in the B feeder 20B that guides the carrier tape 2 of the reel 3 to the parts picking position S within the feeder body 30. That is, the second tape introduction section 38 guides the carrier tape 2 wound around the reel 3, which is held in the reel holder 41, to the parts picking position S when the feeder body 30 and the holder section 40 are in a second positional relationship by the second locking section 52.
[0062] The second tape introduction section 38 has a second inlet 38a and a second introduction passage 38b. The second inlet 38a is an opening that opens to the outside of the feeder body 30. The second inlet 38a is the entrance through which the carrier tape 2, pulled out from the reel 3 in the reel holder 41, passes when it is introduced into the feeder body 30. The second inlet 38a is located in a different position from the first inlet 37a in the feeder body 30. The second introduction passage 38b extends from the second inlet 38a toward the parts picking position S as a transport path 33, and is the passage through which the carrier tape 2 that has passed through the second inlet 38a flows. A part of the first introduction passage 37b (especially the latter half) and a part of the second introduction passage 38b (especially the latter half) are common to each other. Specifically, the second introduction passage 38b merges with the first introduction passage 37b midway.
[0063] The feeder 20 includes a control unit 60. The control unit 60 controls the drive of the feed drive source 31 and the drive of the winding drive source 35. The control unit 60 is mainly composed of a microcomputer and includes a control board and the like. The control unit 60 is located in the feeder body 30. The control unit 60 is electrically connected to the feed drive source of the feed drive source 31 and is also electrically connected to the winding drive source 35.
[0064] The feeder 20 is equipped with an electrical connector 61. The electrical connector 61 is an external connector that electrically connects to the connector 13 of the feeder set stand 10, thereby electrically connecting the control unit 60 and the main control unit of the component mounting machine 1. The electrical connector 61 is located at the front end of the feeder main body 30.
[0065] Furthermore, the drive of the feed drive source 31 and the drive of the winding drive source 35 by the control unit 60 may be performed in synchronous motion. In this case, each of these drive sources may be driven intermittently so that the carrier tape 2 is transported intermittently at predetermined intervals. In addition to controlling the drive of the feed drive source 31 and the winding drive source 35, the control unit 60 may also have a function to manage the feeder information of the feeder 20. In particular, the control unit 60 may be able to associate and link the feeder information of the feeder body 30 with the feeder information of the holder section 40 (reel holder 41 and collection box 42) attached to the feeder body 30.
[0066] The feeder information described above refers to information associated with unique identification information defined for each feeder body 30, each holder 40, and each reel 3. The feeder information may include, for example, the type and identification information of the tape guide 34 attached to the feeder body 30, the size of the reel holder 41, the type and identification information of the reels 3 stored in the reel holder 41, and the type and tape width of the carrier tape 2.
[0067] Each of the housings of the feeder main unit 30, the holder unit 40, and the reel 3 is fitted with a label or plate containing feeder information related to itself. This feeder information can be read using a predetermined reading device. This reading of feeder information is performed in an external setup area. The read feeder information is sent to the host computer for storage and, after storage, is used for matching associated feeder information. The host computer is positioned above the feeder 20 and is a device that integrates and controls components such as the parts mounting machine 1.
[0068] 4. Effects of the Feeder In the feeder 20 described above, the feeder body 30 and the holder 40 are provided separately. Before the holder 40 is attached to the feeder body 30, the reel 3 on which the carrier tape 2 is wound is held in the reel holder 41 of the holder 40 by operation by an operator or robot in an external setup area.
[0069] For example, when a reel 3 with an empty carrier tape 2 is held in the reel holder 41, a new reel 3 is set in the reel holder 41 by replacing the empty reel 3. At the same time, in the B feeder 20B, when a collection box 42 with the cover tape 2b wound up is attached to the feeder body 30, a new collection box 42 is set in place by replacing the collection box 42.
[0070] The holder unit 40 can be transported after the reel 3 and collection box 42 are set up as described above, and can be positioned relative to the feeder body 30 at the mounting unit 50 and attached to the feeder body 30 by operation by an operator or robot. Multiple holder units 40 can be stored together in a reel storage unit (not shown) of the buffer station. Each holder unit 40 in the reel storage unit can be selected and attached to the feeder body 30. The selection of the holder unit 40 is performed by a host computer according to the production plan of the circuit board, and the removal of the selected holder unit 40 from the reel storage unit may be performed using a robot or the like.
[0071] The feeder body 30 and the holder 40 are mounted to each other by being positioned at the mounting portion 50 and clamped in a predetermined positional relationship. Specifically, in feeder A 20A, the feeder body 30 and the reel holder 41 of the holder 40 are mounted to each other in a first positional relationship. In feeder B 20B, the feeder body 30 and the reel holder 41 and the collection box 42 of the holder 40 are mounted to each other in a second positional relationship.
[0072] After the feeder body 30 and holder 40 are attached as described above, the carrier tape 2 is pulled out from the reel 3 of the reel holder 41 and supported on the transport path 33 of the feeder body 30. Then, the cover tape 2b is peeled off from the base tape 2a at the tip of the carrier tape 2. The base tape 2a is then engaged with the feed sprocket 32 of the feed drive source 31, and the cover tape 2b is folded back at the folded portion and guided to the tensioner and winding gear 36 inside the feeder body 30.
[0073] The feeder 20, with its feeder body 30 and holder 40 integrated, is mounted in the slot 11 of the component mounting machine 1. Feeder A 20A is mounted in the slot 11 of the A feeder set stand 10A, and feeder B 20B is mounted in the slot 11 of the B feeder set stand 10B. When power can be supplied to the feeder 20 by mounting the feeder 20 in the slot 11, the control unit 60 in the feeder body 30 is activated, and the feed drive source 31 and the winding drive source 35 become able to drive according to commands from the control unit 60.
[0074] When the feed drive source 31 is driven by a command from the control unit 60, the carrier tape 2 is fed and transported along the transport path 33 in the tape transport direction X. When the winding drive source 35 is driven by a command from the control unit 60, the cover tape 2b is guided along the recovery path to outside the feeder 20 or to the recovery box 42. In this case, the base tape 2a of the carrier tape 2 is intermittently fed along the transport path 33 toward the part picking position S, transferring from the reel holder 41 to the feeder body 30 by the feed drive force of the feed drive source 31, while the cover tape 2b, peeled off from the base tape 2a, is discharged outside the feeder 20 or recovered in the recovery box 42 by the winding drive force of the winding drive source 35.
[0075] As a result, the components stored in each component storage section of the base tape 2a are sequentially exposed and can be removed to the outside. After being exposed, when these components reach the component picking position S, they are held by the suction nozzle of the component mounting machine 1 and transferred to the substrate. When a component is picked up at the component picking position S, the feed drive force from the feed drive source 31 causes the portion of the base tape 2a containing the component storage section from which the component has been removed to be discharged as waste tape from the tape discharge port on the front side of the feeder 20.
[0076] When the amount of carrier tape 2 stored on the reel 3 in the feeder 20 becomes low, or when the feeder 20 is no longer scheduled to be used in the component mounting machine 1, the feeder 20 is removed from the slot 11 of the component mounting machine 1, and the holder section 40 is removed from the feeder body 30 in an external setup area or similar location. During this removal, the base tape 2a is cut at the waste tape portion or similar. After the holder section 40 is removed from the feeder body 30, a new holder section 40, or a holder section 40 with a new reel 3 or a new collection box 42 attached, is attached to the feeder body 30, and the feeder 20 is then mounted in the slot 11 of the component mounting machine 1.
[0077] Thus, in the feeder 20, the feeder body 30 and the holder 40 are detachably attached to each other by the mounting portion 50. The feeder body 30 includes a feed drive source 31 for feeding and transporting the carrier tape 2 (specifically, the base tape 2a), and a feed sprocket 32 for applying the feed drive force generated by the feed drive source 31 to the carrier tape 2. The holder 40 also includes a reel holder 41 that rotatably holds the reel 3.
[0078] In the structure of this feeder 20, the feeder body 30, which has a feed drive source 31 and a feed sprocket 32 for feeding and driving the carrier tape 2, and the holder 40, which has a reel holder 41 for rotatably holding the reel 3, are detachable from each other. Therefore, for example, when a component of the carrier tape 2 runs out in the feeder 20 due to substrate production, the holder 40 can be removed from the feeder body 30, thereby separating the reel 3 with the component loss from the feeder body 30, which includes the feed drive source 31 and the feed sprocket 32. Then, by detachably attaching the holder 40 that holds the new reel 3 to the feeder body 30, a feeder 20 can be constructed in which the reel 3 is integrated with the feeder body 30.
[0079] Furthermore, the feeder body 30 includes a winding drive source 35 that generates winding drive force to wind up the cover tape 2b peeled off the base tape 2a, and a winding gear 36 that applies the winding drive force to the cover tape 2b. In the B feeder 20B, the holder 40 further includes a collection box 42 for collecting the cover tape 2b peeled off the base tape 2a.
[0080] In the structure of this feeder 20, the feeder body 30, which has a winding drive source 35 and a winding gear 36 for winding up the cover tape 2b, and the holder 40, which has a collection box 42, are detachable from each other. Therefore, for example, when a shortage of carrier tape 2 occurs in the feeder 20 due to substrate production, the holder 40 can be removed from the feeder body 30, thereby separating the collection box 42, which is full of cover tape 2b, from the feeder body 30, which includes the winding drive source 35 and the winding gear 36. Then, by detachably attaching the holder 40 with a new collection box 42 to the feeder body 30, a feeder 20 can be constructed in which the collection box 42 is integrated with the feeder body 30.
[0081] The mounting section 50 includes a first locking section 51 for mounting the feeder body section 30 and the holder section 40 in a first positional relationship, and a second locking section 52 for mounting the feeder body section 30 and the holder section 40 in a second positional relationship. The feeder 20 becomes an A feeder 20A when the feeder body section 30 and the holder section 40 are mounted in a first positional relationship by the first locking section 51, and becomes a B feeder 20B when the feeder body section 30 and the holder section 40 are mounted in a second positional relationship by the second locking section 52. When the feeder body section 30 and the holder section 40 are mounted in a first positional relationship, the collection box 42 is not attached to the reel holder 41, and when the feeder body section 30 and the holder section 40 are mounted in a second positional relationship, the collection box 42 is attached to the reel holder 41 by the attachment / detachment section 43.
[0082] In other words, the feeder body 30 and the holder 40 are mounted in a first positional relationship when the collection box 42 is not attached to the reel holder 41, and in a second positional relationship when the collection box 42 is attached to the reel holder 41 by the attachment / detachment part 43.
[0083] According to the structure of the feeder 20 described above, a common feeder body 30 can be used to construct both the A-feeder 20A and the B-feeder 20B. Furthermore, when constructing the A-feeder 20A and the B-feeder 20B, a common reel holder 41 can be used while changing the mounting position, which is the assembly configuration of the reel holder 41 to the feeder body 30. Therefore, the feeder 20 allows for the commonization of the feeder body 30 and the reel holder 41. As a result, it is not necessary to prepare an entire feeder including the drive unit and holder unit for each type, which reduces equipment costs and manufacturing costs for feeder operation, and also saves storage space for the feeder 20.
[0084] In other words, in the feeder 20 structure described above, the holder section 40 does not house the feed drive source 31, feed sprocket 32, winding drive source 35, winding gear 36, and control unit 60. Therefore, the holder section 40 itself is less expensive than the entire feeder 20 including the feeder body section 30. Consequently, even when it is necessary to prepare surplus equipment considering, for example, changeovers, it is not necessary to prepare the entire feeder 20 including the feeder body section 30 as surplus equipment; it is sufficient to prepare only the holder section 40 as surplus equipment. This makes it possible to keep the equipment costs for feeder operation lower compared to when the entire feeder 20 including the feeder body section 30 is prepared as surplus equipment. In addition, the space for storing surplus equipment in the external setup area can be limited to the holder section 40. This makes it possible to save space when storing the feeder 20.
[0085] In particular, in the feeder structure described above, even for parts that are not used frequently, it is sufficient to provide a carrier tape 2 for storing the parts and a reel holder 41 for holding the reel 3 around which the carrier tape 2 is wound, within the feeder 20. This reduces equipment costs and saves storage space.
[0086] Furthermore, the feeder body 30 has a first tape introduction section 37 corresponding to the A feeder 20A and a second tape introduction section 38 corresponding to the B feeder 20B. The first tape introduction section 37 guides the carrier tape 2 of the reel 3 held by the reel holder 41 in the A feeder 20A to the parts picking position S in the feeder body 30. The first tape introduction section 37 has a first inlet 37a and a first introduction passage 37b extending from the first inlet 37a toward the parts picking position S. The second tape introduction section 38 guides the carrier tape 2 of the reel 3 held by the reel holder 41 in the B feeder 20B to the parts picking position S in the feeder body 30. The second tape introduction section 38 has a second inlet 38a provided at a different position from the first inlet 37a, and a second introduction passage 38b extending from the second inlet 38a toward the parts picking position S and merging with the first introduction passage 37b midway.
[0087] In this feeder 20 structure, the transport path of the carrier tape 2 within the feeder body 30 can be made compatible with both A feeder 20A and B feeder 20B, which have different assembly configurations, thereby increasing the versatility of the feeder body 30.
[0088] Furthermore, the feeder body 30 has three body-side engaging portions 53a, 53b, and 53c, which constitute the first locking portion 51 and the second locking portion 52. The holder portion 40 has three holder-side engaging portions 54a, 54b, and 54c, which constitute the first locking portion 51 and the second locking portion 52.
[0089] In the A feeder 20A, the first locking part 51 consists of a second engaging part 53b on the main body side and a first engaging part 54a on the holder side, which engage with each other via a screw 55, thereby mounting the feeder main body 30 and the reel holder 41 of the holder part 40 in a first positional relationship. In the B feeder 20B, the second locking part 52 consists of a first engaging part 53a on the main body side and a first engaging part 54a on the holder side, which engage with each other via a screw 55, and a second engaging part 53b on the main body side and a second engaging part 54b on the holder side, which engage with each other via a screw 55, as well as a third engaging part 53c on the main body side and a third engaging part 54c on the holder side, which engage by fitting, thereby mounting the feeder main body 30 and the reel holder 41 and collection box 42 of the holder part 40 in a second positional relationship.
[0090] In the structure of this feeder 20, the feeder body 30 and the holder 40 can be made compatible with both A-feeder 20A and B-feeder 20B, which have different assembly configurations, thereby increasing the versatility of the feeder body 30 and the holder 40.
[0091] Furthermore, in the feeder 20, when the holder section 40 is attached to the feeder body section 30, the feeder information of the feeder body section 30 and the holder section 40, and the tape information of the reel 3 are read by a predetermined reading device, and each piece of information is associated with each other and stored in a memory unit such as a host computer. After the information is stored, the setting of the feeder 20 into the slot 11 of the component mounting machine 1 is controlled based on that information. Therefore, the feeder 20 can be assembled with the feeder body section 30 and the holder section 40 in one assembly configuration selected from multiple configurations, and that assembly configuration can be associated with the carrier tape 2, enabling the component mounting of components onto the circuit board by the component mounting machine 1 to be performed appropriately.
[0092] Furthermore, when the holder unit 40 is removed from the feeder body unit 30 of the feeder 20, the feeder information of the feeder body unit 30 and the holder unit 40, as well as the tape information of the reel 3, are read, and the feeder information is deleted from the storage unit. Therefore, the association between the feeder 20 and the carrier tape 2 can be dissolved after the holder unit 40 is removed from the feeder body unit 30, thus avoiding the association continuing unnecessarily for a long period of time.
[0093] In the above embodiment, the main body side engaging portion 53 corresponds to the "one side engaging portion" described in the claims, the main body side first engaging portion 53a corresponds to the "one side first engaging portion" described in the claims, the main body side second engaging portion 53b corresponds to the "one side second engaging portion" described in the claims, the main body side third engaging portion 53c corresponds to the "one side third engaging portion" described in the claims, the holder side engaging portion 54 corresponds to the "other side engaging portion" described in the claims, the holder side first engaging portion 54a corresponds to the "other side first engaging portion" described in the claims, the holder side second engaging portion 54b corresponds to the "other side second engaging portion" described in the claims, and the holder side third engaging portion 54c corresponds to the "other side third engaging portion" described in the claims.
