FIG. 1 is a front view of main parts of a pull-tab assembly device 100, and FIG. 2 is an exploded perspective view of a slider provided with a pull-tab 13.

The pull-tab assembly apparatus 100 of this structure is an apparatus which assembles the pull-tab 13 on each slider main body 15 (refer FIG. 2) conveyed intermittently. The pull-tab assembly device 100 includes a slider transport path P1, a reversing unit P2, a reversing driving unit P3, a positioning unit P4, and a pressing unit P5.

In the following description, in the pull-tab assembly device 100 shown in FIG. 1, the up, down, left, and right directions are the directions when the device is viewed from the front, the direction toward the front side of the device is taken as the front, and the direction toward the back side of the device The direction is set to the rear.

As shown in FIG. 2, the slider 11 has a tab mounting post 17. The base end 17 a of the tab mounting post 17 is connected to the upper wing plate 15 a of the slider body 15, and the free end 17 b of the tab mounting post 17 is not connected to the top. The flap 15a is connected. The handle 13 has an opening 19 formed at one end in the longitudinal direction. One end of the opening 13 side of the slider 13 is inserted into the gap between the free end 17b of the slider mounting post 17 of the slider 11 and the upper wing plate 15a of the slider body 15. That is, the free end 17b of the pull-tab mounting post 17 is inserted into the opening hole 19 of the pull-tab 13. Then, the slider 11 is pressurized from above in the direction indicated by the arrow P with the free end 17b of the tab mounting post 17 inserted from the opening 19 of the tab 13. As a result, the pull-tab mounting post 17 is compressed, thereby preventing the pull-tab 13 from falling off from the pull-tab mounting post 17.

The pull-tab assembly device 100 shown in FIG. 1 conveys the above-mentioned slider body 15 and pull-tab 13 separately, assembles the pull-tab 13 on the pull-tab mounting post 17 and compresses the pull-tab mounting post 17, thereby producing a tape pull片的拉头11。 The slider 11. Hereinafter, the slider conveying path P1, the reversing unit P2, the reversing driving unit P3, the positioning unit P4, and the pressing unit P5 will be described respectively.

The slider conveying path P1 is an intermittent conveying conveying path that operates by drawing a rectangular trajectory in the vertical plane of the conveying path, and the plurality of slider bodies 15 are sequentially conveyed while maintaining a predetermined fixed interval along the conveying direction. The slider conveyance path P1 of this structure conveys the slider body 15 from the right side of FIG. 1 toward the left side.

FIG. 3 is a perspective view of the reversing unit P2, and FIG. 4 is a front view of the reversing unit P2.

As shown in FIGS. 3 and 4, the turning unit P2 has a rotating shaft 21, which rotates The shaft 21 is inclined along an axis Ax1 inclined at an inclination angle α of 45° with respect to the slider conveying direction STD (left-right direction in the figure) of the slider conveying path P1, and the reversing unit P2 is freely rotatable around the rotating shaft 21 Support. The pair of pull-tab clamping portions 23A and 23B that support the pull-tab 13 are disposed on the reversing unit P2 with the rotary shaft 21 as the axis of symmetry away from the rotary shaft 21 by an equal distance from each other. That is, the pull-tab clamping portions 23A and 23B are arranged at equal radial distances from each other with respect to the axis Ax1.

In the state shown in FIGS. 3 and 4, the pull-tab clamping parts 23A and 23B are arranged as follows: one pull-tab clamping part 23A is arranged at the pull-tab supply position (first position) PO1 for supplying the pull-tab 13 and the other The pull-tab clamping portion 23B is arranged at a pull-tab assembly position (second position) PO2 that assembles the pull-tab 13 to the slider body 15 transported by the slider transport path P1. The flip drive unit P3 (refer to FIG. 1 ), which will be described in detail later, rotates the flip unit P2 from this state by 180 degrees around the rotating shaft 21 on the axis Ax1 to invert the drive, thereby arranging the pull-tab clamping unit 23A at The pull-tab assembly position PO2, and the pull-tab clamping part 23B is arrange|positioned at the pull-tab supply position PO1. In other words, the reversing drive unit P3 alternately arranges the pair of pull-tab clamping parts 23A and 23B at the pull-tab supply position PO1 and the pull-tab assembly position PO2.

The handle clamping parts 23A and 23B include a flat base 25 on which the handle 13 is placed, and a jig 27 that clamps the handle 13 to the base 25 in the thickness direction of the handle. The pedestal 25 is parallel to the slider transport direction STD at the slider supply position PO1 and becomes the horizontal direction, and crosses the slider transport direction STD at the slider assembly position PO2 to become the vertical direction. In addition, in order to prevent slippage and damage of the pull tab 13, it is preferable to lay a non-slip member such as a resin plate or a resin sheet on the surface of the base 25.

5 is a diagram showing the clip at the position PO1 where the pull-tab of the reversing unit P2 is supplied The operation explanatory view of the state after the tool 27 is released from clamping.

When the follower 33 provided at the front end of the clamp release lever 31 to be described later is pressed as shown by arrow PA in the figure, the clamp 27 of the pull-tab supply position PO1 is released from clamping as shown by arrow QA in the figure. In this state, the pull-tab 13 is supplied to the pedestal 25 of the pull-tab supply position PO1 by a pull-tab transport mechanism such as a robot arm (not shown).

In addition, in the slider conveyance path P1, the slider body 15 is conveyed so that the free end 17b of the handle attachment post 17 may be ahead in the slider conveyance direction STD. As a result, the free end 17b of the handle attachment post 17 is inserted into the opening hole 19 of the handle 13 supported by the handle clamping portion 23B of the handle assembly position PO2. At this time, the jig 27 of the pull-tab assembly position PO2 is in a state where the opening 19 of the pull-tab 13 is inserted into the pull-tab mounting post 17 of the slider body 15. In this state, the slider 13 is clamped to the pedestal 25 while being inclined in the direction indicated by the arrow QB in the drawing due to the transportation of the slider body 15.

That is, in the reversing unit P2, first, the handle clamping part 23A of the handle supply position PO1 is unclamped, and the handle 13 is placed on the pedestal 25 by a handle conveying mechanism such as a robot arm. The slider 13 placed on the base 25 is clamped by the clamp 27 of the slider clamping part 23B. Then, the reversing unit P2 is turned 180 degrees around the axis Ax1 by the reversing drive unit P3, and the pull-tab clamping unit 23A moves from the pull-tab supply position PO1 to the pull-tab assembly position PO2. At the pull-tab assembly position PO2, the pull-tab 13 clamped by the jig 27 is attached to the pull-tab mounting post 17 of the slider main body 15 conveyed by the slider conveyance path P1.

6 is an enlarged perspective view of the pull-tab assembly position PO2.

At the slider assembly position PO2 of the slider conveyance path P1, a pressing unit P5 for pressing the slider mounting post 17 of the slider body 15 is arranged. The pressing unit P5 has The lift slider 43 provided on the hold-down frame 41 is freely liftable. The lifting slider 43 has a punch 45 disposed above the pull-tab mounting post 17 of the slider body 15, and presses and presses the pull-tab mounting post 17 by the lowering operation with respect to the pressing frame 41. The slider attachment column 17 is compressed, and the slider 11 to which the slider 13 is attached is conveyed toward the downstream side in the conveyance direction on the slider conveyance path P1.

According to the reversing unit P2 of the above structure, the supply side of the pull-tab 13 and the assembly side of the pull-tab 13 are separately arranged. Therefore, the handle 13 positioned at the handle supply position PO1 can be arranged at the handle assembly position PO2 while maintaining its positioning state. Therefore, the positional error between the pull-tab supply and the pull-tab assembly is reduced, and it is possible to prevent the pull-tab 13 from entering the pull-tab mounting post and being mistakenly transported or other assembly errors in advance. In addition, since the pull tab 13 is placed and clamped on the flat base 25, various pull tabs 13 having different shapes can be easily assembled to the slider body without complicated adjustment work. In addition, even special-shaped pull tabs can be easily handled.

Conventionally, every time the type of the pull tab 13 is changed, it is replaced with a dedicated pull tab supply chute and adjusted. However, according to this structure, such a complicated replacement operation is no longer necessary. In addition, since the clamping is based on the elastic force of the spring, it is no longer necessary to adjust the clamping force. Therefore, the replacement can be performed simply and quickly, thereby improving the productivity of the slider and realizing efficient automatic production.

Here, a more specific mechanism and operation of the reversing unit P2 will be described.

7 is a schematic configuration diagram of the reversing unit P2 that schematically shows the internal structure of the reversing unit P2.

As shown in Figures 5 and 7, the flip unit P2 has a trapezoidal shape when viewed from the front The frame 51 serves as a base. The frame 51 is a symmetrical shape centered on the axis Ax1, and has an upper surface 51a, a lower surface 51b, and a pair of inclined surfaces 51c. The pair of inclined surfaces 51c intersect the axis Ax1 at an inclination angle of 45° and become mutually orthogonal surfaces.

The frame 51 is formed with a through hole 53 penetrating the upper surface 51a and the lower surface 51b along the axis Ax1. The rotating shaft 21 fixed to the base member 55 is inserted into the through hole 53. The rotating shaft 21 rotatably supports the frame 51 via a rolling bearing 57.

The driven gear 61 is attached to the lower surface 51b side of the frame 51 on the base member 55 side. The rotating shaft 21 is inserted into the inner peripheral surface of the driven gear 61, and the driven gear 61 rotates together with the rotation of the rotating shaft 21. The driven gear 61 meshes with a drive gear 63 (refer to FIG. 7) described in detail later, and the drive frame 51 is reversed by the drive of the drive gear 63.

The pair of inclined surfaces 51c of the frame 51 are provided with the aforementioned pull-tab clamping portions 23A and 23B. Since the handle clamping parts 23A and 23B and its driving mechanism have the same structure with the axis Ax1 as the axis of symmetry, the handle clamping unit 23A and its driving mechanism will be described here.

The pedestal 25 of the pull-tab clamping portion 23A is arranged parallel to the inclined surface 51c of the frame 51. A jig 27 is arranged on the upper surface side of the pedestal 25 so as to be elastically biased toward the pedestal 25. The jig 27 has a first arm member 67 (refer to FIG. 3 at the same time) provided across the front-rear direction of the pedestal 25, a roller 69 supported in parallel with the pedestal 25, and a first rotation support portion 71. The first rotation support portion 71 rotatably connects the first arm member 67 and the second arm member 73. Between the second arm member 73 and the first arm member 67 The first spring material 75 is provided. The first spring material 75 is a tension spring that urges the first arm member 67 clockwise in the figure around the first rotation support portion 71. The first arm member 67 is restricted from rotating in the clockwise direction in the drawing by a stopper (not shown). In other words, the first arm member 67 is urged clockwise in the figure with the first rotation support 71 as the center, and is rotatably supported in the counterclockwise direction in the figure.

In addition, as for the second arm member 73, a second spring material 77 is suspended between the second arm member 73 on the side of the pull-tab assembly position PO2. The second spring material 77 is a tension spring that urges the second arm member 73 clockwise in the figure about the arm rotation axis 79.

That is, the clamp 27 generates a pressing force to the pedestal 25 by urging the first arm member 67 and the second arm member 73 clockwise in the figure by the second spring material 77. In addition, the first arm member 67 is also urged to the pedestal 25 by the first spring material 75. Therefore, the jig 27 combines forces in different directions based on the first spring material 75 and the second spring material 77 to reliably hold the pull tab 13 on the pedestal 25 via the roller 69.

Next, the unclamping of the jig 27 will be described.

The upper surface 51 a of the frame 51 is provided with a lever support portion 81 that supports the L-shaped clamping release lever 31 in a swingable manner. A follower 33 is provided at one end of the clamp release lever 31, and a groove 83 is formed at the other end.

In the groove 83 of the clamp release lever 31, a locking pin 87 protruding outward from the end face of the outer peripheral portion of the first gear 85 supported on the frame 51 in the axial direction is locked. the first The gear 85 meshes with a second gear 89 provided coaxially with the arm rotation shaft 79.

Therefore, when the follower 33 is pressed, the clamp release lever 31 rotates about the lever support 81 and drives the locking pin 87 locked in the groove 83 in the circumferential direction of the first gear 85. In this way, the first gear 85 rotates clockwise in the figure, and drives the second gear 89 counterclockwise in the figure. When the second gear 89 is driven in the counterclockwise direction in the figure, the second arm member 73 and the second gear 89 rotate in the counterclockwise direction in the figure, and the clamp 27 rotates away from the pedestal 25 (refer to the arrow in FIG. 5) QA). Thereby, the clamping by the clamp 27 is released.

When the follower 33 of the clamp release lever 31 is released, the second arm member 73 rotates clockwise in the figure by the elastic restoring force of the second spring material 77. In this way, the locking pin 87 is driven in the circumferential direction via the second gear 89 and the first gear 85, and the clamp release lever 31 returns to the original position. Thereby, the clamping by the jig 27 starts again.

Next, the reversing drive unit P3 shown in FIG. 1 that reversely drives the reversing unit P2 will be described.

Although not shown, the reversing drive unit P3 uses a linear motion driven shaft as a drive source, which is provided at the lower portion of the pull-tab assembly device 100 and is raised and lowered by a crank mechanism or a cam mechanism that is rotationally driven by a motor action. In addition, the aforementioned pressing unit P5 and the positioning unit P4 described later also operate using the linearly driven shaft as a power source. Each of the linearly driven driven shafts moves up and down at a predetermined timing by a crank mechanism or a cam mechanism. Thereby, the operation timing of each part can be easily synchronized.

Next, the positioning unit P4 will be described.

8 is a front perspective view of the positioning unit P4 viewed from the front, FIG. 9 FIG. 10 is a plan view of the positioning unit P4, and FIG. 10 is a rear perspective view of the positioning unit P4 viewed from the rear.

The positioning unit P4 is disposed opposite to the handle clamping part 23A of the handle supply position PO1 shown in FIG. 1, and positions the handle 13 supplied to the handle clamping part 23A at a predetermined position. As shown in FIGS. 8 to 10, the positioning unit P4 includes a contact block 161 and a pull-tab pulling mechanism 165 that are arranged to face the pull-tab clamping portion 23A of the pull-tab supply position PO1. The pull-tab pull mechanism 165 includes a pin (insertion member) 163 having a diameter that can be inserted into the opening 19 (see FIG. 2) of the pull-tab 13, and the pin 163 is inserted into the opening 19 of the pull-tab 13 Pull toward the abutment block 161. The pin 163 as an insertion member may be any shape that can be inserted into the opening 19 of the pull-tab 13 and moves the pull-tab 13, and is not limited to the pin shape, and may be other shapes or components.

As shown in FIG. 9, the block driving mechanism 169 and the pull-tab pulling mechanism 165 that drive the contact block 161 are arranged in parallel on the base 167. The block driving mechanism 169 and the pull-tab pulling mechanism 165 are respectively connected to the link mechanism 171, and the link mechanism 171 can move forward and backward in the left-right direction in the figure.

The link mechanism 171 has a first link member 173, a second link member 175, and a coupling member 177. One end portion of the first link member 173 on the left side in the figure is connected to a block driving mechanism 169 that supports the contact block 161. The left end of the second link member 175 in the figure is connected to the pull-tab pulling mechanism 165. The connecting member 177 connects the other end of the first link member 173 and the other end of the second link member 175 via the swing shaft 179, and a swing member 177 is provided between these other ends The swing shaft 179 is movably supported. In other words, the swing shaft 179 is arranged between the other end of the first link member 173 and the other end of the second link member 175.

As shown in FIG. 10, the connecting member 177 is connected to the tie rod 181 at the end that crosses the first link member 173 from the swing shaft 179. The end of the tie rod 181 on the opposite side to the connecting member 177 is connected to the one end 183 a of the L-shaped rod 183. The L-shaped lever 183 is swingably supported on the base 167 by a swing shaft 185 provided in an L-shaped bent portion. The other end 183b of the L-shaped lever 183 is connected to the linear driven shaft 94.

According to this link mechanism 171, when the straight-line driven shaft 94 moves up and down (in the PD1 direction in the figure), the L-shaped lever 183 swings (in the PD2 direction in the figure), and the pull rod 181 reciprocates (in the PD3 direction in the figure). In this way, the first link member 173 and the second link member 175 reciprocate (the PD5 and PD6 directions in the figure) by the swing of the coupling member 177 (the PD4 direction in the figure). At this time, the first link member 173 and the second link member 175 move in directions opposite to each other. When one direction moves to the right, the other direction moves to the left.

Next, the pull-tab pulling mechanism 165 and the block driving mechanism 169 connected to the link mechanism 171 described above will be described more specifically.

FIG. 11 is a partial cross-sectional configuration diagram showing the schematic configuration of the block driving mechanism 169.

The support block 191 is fixed to the base 167. The support block 191 supports one end side of the first slider 193 in the longitudinal direction so as to advance and retract in the left-right direction in the figure. The other end of the first slider 193 in the longitudinal direction is inserted into the groove 197 of the first guide block 195. The first slider 193 is connected to a coupling shaft 187 provided at the front end portion of the first link member 173 on the left side in the figure.

In addition, a spring accommodating portion 199 is formed in the first guide block 195, and a floating spring material 201 is accommodated in the spring accommodating portion 199. The floating spring material 201 is a compression spring that floatingly supports the first guide block 195 relative to the first slider 193 in the left-right direction in the figure. In addition, a pin 203 is provided on the upper surface of the first slider 193. The pin 203 is inserted into a long hole-shaped pin hole 205 formed in the first guide block 195.

The abutment block 161 is supported on the left side of the first guide block 195 in the figure. The abutment block 161 follows the forward and backward movement of the first link member 173 and can move in the left-right direction in the figure. In addition, the movable range of the contact block 161 can be adjusted by the stopper 207 and the stopper 209 (refer to FIG. 9 ).

FIG. 12 is a partial cross-sectional configuration diagram showing the schematic configuration of the pull-tab pulling mechanism 165.

The support block 191 supports the one end side of the second slider 211 (sliding member) in the longitudinal direction so as to advance and retract in the left-right direction in the figure. The other end side of the second slider 211 in the longitudinal direction is inserted into the groove portion 215 of the second guide block 213.

A floating spring material 217 connected to the second slider 211 is connected to the second guide block 213. As a result, the second guide block 213 is floatingly supported by the second slider 211 in the left-right direction in the figure. In addition, a pin 219 is provided on the upper surface of the second slider 211. The pin 219 is inserted into the long hole-shaped pin hole 221 formed in the second guide block 213.

In addition, the second guide block 213 has a ring-shaped front end protrusion 223 (see FIG. 8) on the left side in the figure, and an L-shaped lever member 225 is rotatably supported by the front end protrusion 223 about a shaft 227 (rotation support portion). . The lever member 225 is provided with a pin 163 protruding upward at one end 225a on the left side in the figure. In addition, at the other end 225b The spring material 229 connected to the second guide block 213 is connected. As the spring material 229, a material having an elastic constant larger than the floating spring material 217 is used.
