Detailed Description

Hereinafter, various embodiments and features of the present invention will be described with reference to fig. 1 to 14. Those skilled in the art will appreciate that embodiments and/or features may be combined without undue experimentation and that synergistic effects based on such combinations may also be appreciated by those skilled in the art. In principle, a repetitive description between the embodiments is omitted. The drawings are mainly for describing the invention and may be simplified for convenience of drawing.

Fig. 1 is a schematic perspective view of a combination of an unbonded slider body 10 and a locking member 20 processed by a slider assembling machine. Fig. 2 is a schematic plan view of the pull tab 30 processed by the slider assembling machine. In the present specification, the slider (the slider body 10, the locking member 20, or the pull tab 30) has a front-rear direction that coincides with a slider moving direction for opening and closing the slide fastener. The zipper is closed by the advancement of the slider. The slide fastener is opened by the retraction of the slider. The vertical direction is a direction perpendicular to a fastener tape of a slide fastener to be opened and closed by a slider. The left-right direction is a direction orthogonal to the front-back direction and the up-down direction.

As shown in fig. 1 and 2, the slider includes a slider body 10, a latch member 20, and a pull tab 30. The slider body 10 is made of, for example, metal. The latch 20 is made of, for example, resin, rubber, or metal, and has a desired degree of elasticity for attachment to the slider body 10. The pull tab 30 is a composite part of a metal mounting member 31 and a rubber grip portion 32. The materials of the slider body 10, the latch member 20, and the pull tab 30 are not limited to those described herein.

The slider body 10 has an upper blade 11, a lower blade 12, a coupling post 13, and a pull-tab attachment post 14. The connecting column 13 extends in the vertical direction so as to connect the front end of the upper blade 11 and the front end of the lower blade 12. Left and right flange portions 15 may be provided at left and right side edge portions of the upper blade 11 and/or left and right side edge portions of the lower blade 12. A tape insertion slit 16 is provided between the left and right side edges of the upper blade 11 and/or the lower blade 12 and the flange 15. The tab mounting post 14 is a cantilevered beam that extends from its bonded end 14a in the fore-aft direction all the way to its free end 14b. The joining end 14a of the tab attaching post 14 is joined to the rear end portion of the upper wing panel 11. The free end 14b of the tab attaching post 14 is located above the front end portion of the upper wing panel 11. An upper recess 14e is provided on the upper surface of the free end 14b of the tab attaching post 14. A lower recess, not shown, is provided on the lower surface of the lower blade 12.

As described above, the pull tab 30 is a composite component including the attachment member 31 and the grip portion 32. The attachment member 31 is a component of the pull-tab 30, i.e., a pull-tab component. The attachment member 31 has an attachment ring 31a through which the pull-tab attachment post 14 is inserted. The mounting member 31 is also a core material of the grip portion 32 that is injection molded (but is not necessarily limited thereto). The grip portion 32 is a portion gripped by human fingers, and is, for example, a rubber portion, but is not limited thereto, and may be, for example, a resin portion. The pull tab 30 can be manufactured by introducing a molten material into a molding cavity of a mold apparatus in a state where the attachment member 31 is disposed in the molding cavity, that is, by insert molding.

After the pull-tab mounting post 14 of the slider body 10 is inserted into the mounting ring 31a of the mounting member 31, the latch member 20 is engaged with the slider body 10, and the pull-tab 30 is prevented from falling off from the slider body 10. The locking member 20 has an upper fitting portion 21, a locking portion 22, a leg portion 23, and a lower fitting portion 24. The upper fitting portion 21 is fitted into an upper recess 14e provided at the free end 14b of the tab attaching post 14. The lower fitting portion 24 is fitted in a lower recess provided in the lower blade 12. The latch 22 closes a gap between the free end 14b of the tab attaching post 14 and the front end portion of the upper wing plate 11. The leg portion 23 is received by a groove extending in the up-down direction of the coupling post 13 of the slider body 10. In addition, the specific shape of the latch member is not limited to the illustrated one, and can be thoroughly changed according to the structure of the slider body 10.

The components of the slider to be handled by the slider assembling machine of the present invention are not limited to those shown in fig. 1 and 2. The slider assembling machine of the present invention is also effective for a slider of a type not using the locking member 20, for example, a slider of a type attaching the pull-tab 30 to the slider body 10 by plastic deformation of the pull-tab attaching post 14. Incidentally, in this type of slider, the coupling end 14a of the pull-tab attaching post 14 is coupled to the front end portion of the upper blade 11, and the free end 14b of the pull-tab attaching post 14 is located above the rear end portion of the upper blade 11. The slider assembling machine of the present invention is also effective for a pull tab of a type in which the grip portion 32 is not formed by injection molding, for example, a flat plate-like metal pull tab of a single member.

Hereinafter, the slider assembling machine 40 of the present invention and various features related thereto will be described with reference to fig. 3 to 14. It is assumed that the slider is assembled by the components shown in fig. 1 and 2, but the slider assembling machine of the present invention can be used for assembling various kinds of sliders, not shown. As shown in fig. 3, the slider assembling machine 40 includes a slider body processing part 41 and a pull tab processing part 46. The slider body processed portion 41 and the pull tab processed portion 46 are disposed adjacent to each other. It is envisaged that the slider body processing portion 41 and the tab processing portion 46 are constructed as different devices and are arranged adjacently. Alternatively, a manner in which the slider body treated portion 41 and the tab treated portion 46 are constructed on a common base may be envisaged.

The number of steps of the slider body processing part 41 may be equal to or greater than that of the tab processing part 46 depending on the embodiment. The slider body processing portion 41 has a slider body feeding station S00, a tab mounting station S02, a mounting station S04, and an ejecting station S06. The tab processing section 46 includes an attachment component supply station (tab component supply station) S11, an injection molding station S12, a gate cutting station S13, and a tab delivery station S14. Incidentally, a mode of attaching the pull-tab to the slider body by plastic deformation of the pull-tab attaching post at the attaching station S04 is also conceivable.

The slider body processing portion 41 includes a fixed portion 42 and a rotating portion 43. The rotating portion 43 is provided with 41 st movable portions 51 at equal angular intervals in the circumferential direction. Each 1 st movable portion 51 rotates along the 1 st circular path in accordance with the rotation of the rotating portion 43. Specifically, each 1 st movable portion 51 repeatedly travels along the 1 st circular path by a predetermined angle at predetermined time intervals.

As shown in fig. 4, the 1 st movable portion 51 has 1 or more or a plurality of 1 st arrangement portions 61 in which the slider body 10 is arranged. Although not necessarily limited thereto, the 1 st arrangement portion 61 is configured to hold the slider body 10 such that the tab attaching post 14 of the slider body 10 extends in the vertical direction and the free end of the tab attaching post 14 faces the upper side in the vertical direction. The 1 st movable part 51 includes: a support portion 51g provided with grooves 51s at regular intervals, through which the coupling posts 13 of the slider body 10 are inserted; and a fixing portion 51b to which the supporting portion 51g is fixed. The support portion 51g is, for example, a single thin plate provided with the groove 51s, or a plurality of thin plates arranged with the groove width of the groove 51s therebetween. The thin plate can be inserted into the tape insertion slit 16 of the slider body 10. The 1 st arrangement portion 61 is formed at a position corresponding to the groove 51 s. Incidentally, when the slider body 10 is disposed in the 1 st disposition portion 61, not only the mode in which the tab attaching post 14 extends in parallel with the vertical direction but also the mode in which the tab attaching post 14 extends obliquely with respect to the vertical direction is conceivable.

The rotating portion 43 rotates at regular time intervals by a predetermined angle, 90 ° in the example of the figure. Thereby, the 1 st movable portion 51 disposed on the rotating portion 43 can be moved from a certain station to a station adjacent thereto. The rotating portion 43 is rotated by, for example, torque generated by a stepping motor, but is not limited thereto.

The arrangement of the stations in the slider body processing portion 41 is not limited to the ring shape, and a linear form is also conceivable. A conveyor or a linear actuator may be employed to move the 1 st movable portion 51 between the stations. The details of the mechanism for moving the 1 st movable portion 51 are determined according to the arrangement of the stations. A part or all of the mechanism for performing the work assigned to each station can be attached to the fixing portion 42.

The tab processing portion 46 has a fixing portion 47 and a rotating portion 48. The rotating portion 48 is provided with 42 nd movable portions 52 at equal angular intervals in the circumferential direction. Each 2 nd movable portion 52 rotates along the 2 nd circular path according to the rotation of the rotating portion 48. Each of the 2 nd movable portions 52 repeatedly travels along the 2 nd circular locus by a predetermined angle at predetermined time intervals.

As shown in fig. 5, the 2 nd movable portion 52 has 1 or more or a plurality of 2 nd arrangement portions 62 in which the mounting members 31 (eventually, the tabs 30) are arranged. The rotating portion 48 rotates by a predetermined angle, 90 ° in the illustrated example, at fixed time intervals. This allows the 2 nd movable section 52 disposed on the rotating section 48 to move from a certain station to a station adjacent thereto. The rotating portion 48 is rotated by, for example, torque generated by a stepping motor, but is not limited thereto.

The arrangement of the stations in the tab processing portion 46 is not limited to the ring shape, and a linear form is also conceivable. In order to move the 2 nd movable portion 52 between the stations, a conveyor or a linear actuator is also conceivable. The details of the mechanism for moving the 2 nd movable portion 52 are determined according to the arrangement of the stations. In addition, a part or all of the mechanism for performing the work assigned to each station can be attached to the fixing portion 47.

Each of the 1 st movable portions 51 shown in fig. 4 moves, i.e., circulates, at the stations S00, S02, S04, and S06 of the slider body processing portion 41 in accordance with the rotation of the rotating portion 43. In the slider body feeding station S00, the slider body 10 is fed to the 1 st arrangement portion 61 of the 1 st movable portion 51 by the slider body feeding mechanism 71 j. The slider body feeding mechanism 71j moves in the direction of the dashed arrow corresponding to the arrangement direction of the 1 st arrangement portions 61, and sequentially feeds the slider body 10 to each of the 1 st arrangement portions 61. The slider bodies 10 are fed to the 81 st arrangement portions 61 one by one, but the present invention is not limited to this, and a mode in which a plurality of slider bodies 10 are fed to a plurality of 1 st arrangement portions 61 at the same time is also conceivable.

After the slider body 10 is supplied to the 1 st arrangement portion 61 at the slider body supply station S00, the 1 st movable portion 51 is moved to the tab attaching station S02. The tab attaching station S02 causes the tab attaching post 14 of the slider body 10 to penetrate into the attaching ring 31a of the tab 30 in cooperation with the tab delivery station S14 of the tab handling portion 46. The station arrangement of the slider body processing portion 41 and the station arrangement of the pull tab processing portion 46 are configured such that the pull tab attaching station S02 and the pull tab delivery station S14 are disposed adjacent to each other. The tab attaching station S02 and the tab delivery station S14 may be disposed on a common axis line connecting the rotation center of the rotation portion 43 and the rotation center of the rotation portion 48, but of course, the present invention is not limited thereto. Therefore, before describing the details of the tab attaching station S02, the structure and operation of the tab processing portion 46 will be described.

As shown in fig. 5 (a) and (b) and fig. 6, in the mounting member supply station S11, the mounting member 31 is supplied to the 2 nd arrangement portion 62 of the 2 nd movable portion 52. As shown in fig. 6, a mounting component supply section 76 is provided adjacent to the mounting component supply station S11. The mounting component supply unit 76 is, for example, a belt conveyor. The mounting member 31 is transferred from the belt of the belt conveyor to the 2 nd arrangement portion 62 of the 2 nd movable portion 52, specifically, to the cavity of the lower mold 53. The mounting member 31 is transferred by the holding mechanism 77, but the present invention is not limited thereto, and various other methods such as suction may be adopted.

As shown in fig. 6, the holding mechanism 77 is movable with respect to the belt conveyor and, similarly, with respect to the lower mold 53. The holding mechanism 77 has a plurality of

contact portions

77m, 77n that contact the inner peripheral surface of the mounting ring 31a of the mounting member 31. The intervals between the plurality of

contact portions

77m, 77n can be adjusted. For example, the intervals between the plurality of

contact portions

77m and 77n can be adjusted in a direction parallel to the conveyor surface of the belt conveyor on which the mounting member 31 is disposed. In the acquisition position, the

contact portions

77m, 77n are inserted into the mounting ring 31a, and then the interval between these

contact portions

77m, 77n is enlarged. The

contact portions

77m, 77n contact the inner peripheral surface of the mounting ring 31a, whereby the mounting member 31 is held by the holding mechanism 77. As indicated by the arrow shown in fig. 6, the holding mechanism 77 is moved from the acquiring position to the releasing position. In the release position, the mounting member 31 is released from the holding mechanism 77 by narrowing the interval between the

contact portions

77m and 77n, and is disposed on the 2 nd disposing portion 62, specifically, the lower die 53. In order to realize more stable transfer, a recess 53r (see fig. 6) for avoiding interference with the holding mechanism 77 is provided in the lower die 53, particularly in a movable portion 53e described later. The recess 53r is provided at a position deeper than the recess for disposing the mounting member 31.

A mode is conceivable in which 1 holding mechanism 77 is provided at the station S11 and the mounting members 31 are supplied one by one to the plurality of 2 nd arrangement portions 62. It is also conceivable to provide a plurality of holding mechanisms 77 at the station S11 and supply a plurality of mounting members 31 to a plurality of 2 nd arrangement portions 62 at the same time.

By supplying the mounting member 31 to the 2 nd movable portion 52 in the station S11, as shown in fig. 5 (b), the mounting member 31 is disposed in the 2 nd disposition portion 62 of the 2 nd movable portion 52. In the form of a flat plate-shaped metal pull-tab in which the pull-tab 30 is a single member, the mounting member feeding station S11 is alternatively referred to as a pull-tab feeding station.

Subsequent to the station S11, the 2 nd movable part 52 is moved to the injection molding station S12. At this station S12, a molten or softened material such as a thermoplastic resin or rubber is supplied to the molding cavity of the mold by injection molding, the grip portion 32 is molded, and the grip portion 32 is coupled to the mounting member 31. In some cases, the lower mold 53 is used as the 2 nd movable portion 52, which promotes the smooth process from the arrangement of the mounting member 31 to the injection molding. Specifically, as can be understood from fig. 8, the upper mold 56 is disposed on the lower mold 53, and the cavity of the lower mold 53 and the cavity of the upper mold 56 are spatially combined to form a molding cavity for molding the grip portion 32. A predetermined amount of the molten or softened material supplied from the injection molding machine body 81 is supplied to the molding cavity through a flow path (sprue, runner, and gate) not shown. The material in the molding cavity is solidified by cooling the mold, thereby forming the grip portion 32 (see fig. 9).

Subsequent to the station S12, the 2 nd movable part 52 moves to the gate cutting station S13. In the station S13, the gate portion 32g coupled to the grip portion 32 is cut by the cutter 82. The gate portion 32g is a portion formed by solidification of the molten or softened material at the gate of the flow path of the mold. The same applies to the runner section and the sprue section. In some cases, the gate portion 32g is not completely cut by the cutter 82, and the gate portion is completely cut in correspondence with the displacement of the runner portion or the sprue portion. Thus, the cutter 82 is prevented from contacting the lower die 53, and the life of the cutter 82 is prolonged.

In some forms, the lower die 53 is divided into a fixed portion 53f and a movable portion 53e. In the station S13, the movable portion 53e is moved from the molding position to the retracted position as indicated by an arrow in fig. 10. The movable portion 53e moves in a direction away from the mounting member 31 disposed on the fixed portion 53f, specifically, moves downward in the vertical direction. By this movement of the movable portion 53e, a space is generated below the mounting member 31 disposed on the fixed portion 53f, and the slider body 10 can approach (access) the mounting member 31 from the vertical direction downward. As a result of the displacement of the movable portion 53e relative to the fixed portion 53f, the pull-tab 30 or the pull-tab constituting part is not supported by the movable portion 53e but is supported only by the fixed portion 53f, and a part of the pull-tab 30 or the pull-tab constituting part, for example, the entirety or a part of the mount ring 31a protrudes from the fixed portion 53 f. The displacement prevents the lower die 53 from interfering with the 1 st movable portion 51 in the subsequent tab delivery station S14. Although the pull-tab 30 is no longer supported by the movable portion 53e of the lower die 53, the pull-tab 30 is still stably supported by the fixed portion 53f of the lower die 53. It is also conceivable to move the movable portion 53e of the lower mold 53 from the molding position to the retracted position in the station S14. The molding position and the retracted position are typically disposed at upper and lower sides in the vertical direction, but are not necessarily limited thereto.

As described above, the tab attaching station S02 and the tab delivery station S14 cooperate to insert the tab attaching post 14 of the slider body 10 into the attaching ring 31a of the tab 30. In some embodiments, at least one of the 1 st movable portion 51 located at the tab attaching station S02 and the 2 nd movable portion 52 located at the tab delivery station S14 is moved to attach the tab 30 or the tab component after the 1 st process (injection molding in the above description, but not limited thereto) to the tab attaching post 14 of each slider body 10. By moving the 1 st movable part 51 and/or the 2 nd movable part 52, the plurality of slider bodies 10 and the plurality of pull tabs 30 can be collectively coupled.

For example, in the case where the 1 st process requires a relatively long time, the rotation period of the rotation portion 48 of the tab processing portion 46 becomes long, and in synchronization with this, the rotation period of the rotation portion 43 of the slider body processing portion 41 becomes long. Since the 1 st process is not performed on one pull tab 30 or pull tab constituent part but on a plurality of pull tabs 30 or pull tab constituent parts, and a plurality of slider bodies 10 or pull tab constituent parts or pull tabs 30 are processed correspondingly thereto by other stations, even if the 1 st process requires a relatively long time, it is possible to avoid or suppress a decrease in the assembly efficiency of the entire slider assembly machine 40. The 1 st treatment is 1 or more treatments selected from injection molding, plastic deformation processing, and coloring treatment. In the case of plastic deformation and coloring, it can be understood that the unfinished tab 30 is supplied to the 2 nd arrangement portion 62 of the 2 nd movable portion 52.

The movement of one or both of the 1 st and 2 nd

movable portions

51 and 52 can be performed in various ways. For example, the slider body processing portion 41 and/or the pull tab processing portion 46 is configured to move at least one of the 1 st movable portion 51 located at the pull tab attaching station S02 and the 2 nd movable portion 52 located at the pull tab delivery station S14 so as to attach the respective pull tabs 30 or the pull tab constituent parts subjected to the 1 st process (injection molding in the above description, but not limited thereto) to the pull tab attaching posts 14 of the respective slider bodies 10. In detail, it is possible to perform: the tab attaching station S02 moves the 1 st movable part 51 relative to the 2 nd movable part 52 located at the tab delivery station S14, the tab delivery station S14 moves the 2 nd movable part 52 relative to the 1 st movable part 51 located at the tab attaching station S02, and one or both of the 1 st and 2 nd

movable parts

51, 52 are moved by both the tab attaching station S02 and the tab delivery station S14.

In addition to or in place of the above feature, in some aspects, the slider body processing portion 41 and/or the pull tab processing portion 46 is configured to move at least one of the 1 st and 2 nd

movable portions

51 and 52, and during the movement of at least one of the 1 st and 2 nd

movable portions

51 and 52, the free end of the pull tab attaching post 14 enters the opening of the pull tab 30 or the pull tab constituent member, the pull tab 30 or the pull tab constituent member is hooked to the pull tab attaching post 14, and the pull tab 30 or the pull tab constituent member is detached from the 2 nd disposition portion 62. By moving the 1 st movable part 51 and/or the 2 nd movable part 52, the tab 30 can be stably attached to the tab attaching post 14 of the slider body 10 without, for example, detaching the slider body 10 from the 1 st arrangement part 61.

After the station S13, the 2 nd movable portion 52 moves to the tab delivery station S14. The slider body processing portion 41 is configured to move the 1 st movable portion 51 relative to the 2 nd movable portion 52 in the stop state at the tab delivery station S14. As shown in fig. 11, the 1 st movable part 51 moves toward the 2 nd movable part 52, and the pull-tab attaching post 14 of the slider body 10 is positioned below the attaching ring 31a of the pull-tab 30. Next, the 1 st movable portion 51 moves upward in the vertical direction. In this process, the tab attaching post 14 of the slider body 10 enters the attaching ring 31a of the tab 30 disposed on the fixing portion 53f of the lower die 53, and the tab 30 is hooked to the tab attaching post 14. The movable part 53e moves from the molding position to the retracted position as described above. Therefore, a space is formed below the mounting member 31 disposed in the fixed portion 53f, and the slider body 10 can be moved closer to the mounting member 31 by the movement of the 1 st movable portion 51. Interference of the lower mold 53 with the 1 st movable part 51, which may occur without dividing the lower mold 53, is effectively avoided. When the 1 st movable part 51 reaches the target height as shown in fig. 12, the tab 30 hooked on the tab attaching post 14 is released from the cavity of the 2 nd arrangement part 62, in detail, the fixed part 53 f. Next, the 1 st movable portion 51 is returned to the initial position.

In fig. 11 and 12, the 1 st movable portion 51 is moved, but a mode in which the 2 nd movable portion 52 is moved or a mode in which both the 1 st and 2 nd

movable portions

51 and 52 are moved is also conceivable. The movement locus of the 1 st movable portion 51 is appropriately set according to various factors such as the orientation of the slider body 10 in the 1 st arrangement portion 61, the orientation of the tab 30 in the 2 nd arrangement portion 62, the shape of the slider body 10, and the shape of the tab 30. Various mechanical elements such as a cylinder, a ball screw, a guide member, and a biasing member may be used to move the 1 st movable portion 51. When the 2 nd movable portion 52 is the lower mold 53, the weight of the lower mold 53 cannot be ignored. Therefore, in this case, it is advantageous to move the 1 st movable part 51 instead of the 2 nd movable part 52.

In the tab processing portion 46, the 2 nd movable portion 52 moves from the station S14 to the station S11, and the same processing as described above is repeated.

The 1 st movable portion 51 moves to the mounting station S04 after the station S02. In the station S04, as shown in fig. 13, the locking member 20 is supplied to the slider body 10 and attached. The operation of supplying one slider body 10 and attaching one latch member 20 can be repeatedly performed in the same manner as supplying the slider body 10 to the 1 st arrangement portion 61 shown in fig. 4. In the slider of the type in which the pull-tab 30 is attached to the slider body 10 by plastic deformation of the pull-tab attaching post 14, the plastic deformation of the pull-tab attaching post 14 is performed at this station S04 to prevent the pull-tab 30 from falling off from the slider body 10.

The 1 st movable portion 51 moves to the discharge station S06 after the station S04. A removing mechanism is provided at the ejecting station S06, and the slider body 10 is removed from the 1 st arrangement portion 61 by its operation. In some embodiments, the detaching mechanism includes a detaching tool 83 that contacts the slider body 10 and moves the slider body 10 upward in the vertical direction. The removal tool 83 moves as shown in fig. 14, and removes the slider body 10 from the 1 st arrangement portion 61. The removing tool 83 is a member having a contact end 84, the contact end 84 is in contact with a lower end portion in the vertical direction of the slider body 10 (in the example of the figure, a rear end portion of a lower wing plate of the slider body 10) in a state where the 1 st arrangement portion 61 is arranged, and the removing tool 83 is, for example, a plate material bent at least 1 point. In the illustrated example, the removal tool 83 is an L-shaped plate. The removal tool 83 moves downward from the rear end of the lower blade of the slider body 10, and then moves upward to contact the rear end of the slider body 10, thereby pushing and pulling the slider body 10 upward. The removal tool 83 is moved so that the contact end 84 of the removal tool 83 is positioned below the end of the slider body 10. Next, the removal tool 83 is moved so that the contact end 84 of the removal tool 83 presses the slider body 10 vertically upward. The slider body 10 is moved upward in the vertical direction by the removal tool 83, and then the slider body 10 is separated from the 1 st arrangement portion 61. The coupling post 13 of the slider body 10 is pulled out from the groove 51s of the support portion 51g of the 1 st movable portion 51. A scattering prevention plate 85 for preventing the slider body 10 from scattering can be provided at the station S06.

After the station S06, the 1 st movable portion 51 is moved to the station S00.

Various modifications to the embodiments will be readily apparent to those skilled in the art in light of the above teachings. It is also conceivable that the slider body processing part 41 or the station S02 is configured to move the 2 nd movable part 52 toward the 1 st movable part 51. That is, a mode in which the drive system of the 2 nd movable portion 52 is provided on the slider body processing portion 41 side is conceivable. It is also conceivable that the tab processing portion 46 or the station S14 is configured to move the 1 st movable portion 51 toward the 2 nd movable portion 52. That is, a mode in which the driving system of the 1 st movable portion 51 is provided on the tab processing portion 46 side is conceivable. Reference numerals are set forth in the claims for reference purposes and are not intended to limit the claims.
