More specifically, the insertion device 30 inserts the core thread of the fastener tape 110 and the fastener elements 120 into the slider 180 .

As shown in FIG. 1 , the insertion device 30 is provided on the downstream side of the guide member 905 that guides the conveyance of the fastener chain 100 . Downstream of the guide member 905, there is provided a conveyance path of the fastener chain 100 phantomly shown by a dashed-dotted line. The insertion device 30 can reciprocate between the upstream side and the downstream side in the conveyance path of the fastener chain 100, and can drive the fastener chain 100 to move toward the downstream side in the conveyance direction of the fastener chain 100. The insertion device 30 includes a first clip 10 and a second clip 20 that are arranged adjacent to each other in the left-right direction. The first clamping tool 10 and the second clamping tool 20 are capable of clamping the ends 118 of the respective left and right fastener tapes 110 . In the state where the first clamping part 10 and the second clamping part 20 clamp the end 118 of the zipper tape 110, the insertion device 30 moves toward the downstream side of the chain conveying direction, thereby driving the zipper chain 100 downstream in the same direction.

In one example, the driving mechanism 5 includes an electric cylinder as a linear actuator, and an insertion device 30 is installed at the front end of the cylinder rod. In other examples, the drive mechanism 5 includes a ball screw and a motor for rotating the screw shaft of the ball screw as a linear actuator. In this case, the insertion device 30 is mounted relative to the nut of the ball screw. In other examples, the drive mechanism 5 includes other kinds of linear actuators. In some embodiments, the driving source included in the driving mechanism 5 exemplified above includes a stepping motor, and the position of the insertion device 30 is controlled with high precision by supplying pulses to the stepping motor.

As a further example, the drive mechanism 5 may include any type of motor, a pinion receiving the rotational force of the motor, and a rack engaged with the pinion. The pinion rotates according to the rotational force from the motor. The rack moves forward or backward according to the rotation of the pinion. Insertion means 30 may be fixed at the end of the rack.

As shown in FIG. 10 , the insertion device 30 includes not only the first clamping part 10 and the second clamping part 20 , but also a pusher capable of pressing the first clamping part 10 and the second clamping part 20 . 40, and a driving mechanism 50 capable of moving the pushing member 40. In one aspect of the present disclosure, according to the movement of the push member 40 based on the driving mechanism 50 , the clamping part of the first clamping part 10 clamping the fastener tape 110 and the second clamping part 20 clamping the fastener tape 110 can be adjusted. The left and right spacing of the clamping part. When the insertion device 30 moves from the upstream side to the downstream side in the chain conveying direction, the left-right interval is adjusted to ensure smooth insertion of the left and right element rows L120 into the slider.

As shown in FIG. 9 , the clamping portion of the first clamping tool 10 clamping the fastener tape 110 moves along the movement locus L1. The clamping portion of the second clamping member 20 clamping the fastener tape 110 moves along the movement locus L2.

The core thread of the fastener stringer 170 held by the first holder 10 and the fastener element 120 move along the movement locus L1'. The core thread of the fastener stringer 170 held by the second holder 20 and the fastener element 120 move along the movement locus L2'.

The movement locus L1 and the movement locus L2 have a mirror image relationship with respect to the plane PL100 perpendicularly intersecting the fastener chain 100 at the center in the width direction of the fastener chain 100 . The width direction of the fastener chain 100 refers to the direction perpendicular to the longitudinal direction of the fastener chain 100 . The width direction of the fastener chain 100 is also perpendicular to the thickness direction of the fastener tape. The movement trajectory L1' and the movement trajectory L2' have a mirror image relationship with respect to the plane PL100. Those skilled in the art will surely understand that the mirrored trajectory is beneficial to simplify the structure of the insertion device 30 .

In the device 900 shown in FIG. 1 , the insertion device 30 is illustrated as being movable along a guide rod 999 , but is not necessarily limited thereto. The guide bar 999 is provided parallel to the conveyance path of the fastener chain 100 . In some cases, the driving mechanism 5 includes a ball screw, and the guide rod 999 corresponds to the screw shaft of the ball screw. In some cases, the drive mechanism 5 includes a ball screw, and the guide rod 999 is different from the screw shaft of the ball screw.

In the conveyance path of the fastener chain 100, the 1st slider 181 and the 2nd slider 182 clamped by the 1st slider holding part 910 and the 2nd slider holding part 920 are arrange|positioned. The first slider clamping portion 910 and the second slider clamping portion 920 are sometimes simply referred to as slider clamping portions. The first slider 181 and the second slider 182 are sometimes simply referred to as sliders.

As shown in FIG. 2 , the first slider clamping portion 910 has a pair of arm portions 911, 912 for clamping the tab mounting post 186 of the slider 180 . Each arm part 911,912 has the contact end which contacts the handle attachment column 186, and the opposite end of the opposite side of a contact end. The arm portion 911 has a shape extending from its opposite end toward its contact end and bent at one place so as to approach the other side arm portion 912 . The arm portion 912 also has the same curved shape.

On portions on opposite end sides of the arm portion 911, a rotation shaft is provided, and the arm portion 911 is pivotable about the rotation shaft as a rotation center. The arm portion 912 is also provided with the same rotation axis. A compressed spring 913 is arranged between the opposite ends of the arms 911, 912. Each arm part 911, 912 is biased so that the contact end of each arm part 911, 912 contacts.

Since the first slider clamping portion 910 is constructed as described above, by inserting the handle mounting post 186 of the slider 180 between the contact ends of the arms 911, 912, the first slider clamping portion 910 can The slider 180 is securely held between the arm portions 911 , 912 . The second slider holding part 920 also has the same structure as the first slider holding part 910 . The pair of arms 911 , 912 is replaced by a pair of arms 921 , 922 , and the compressed spring 913 is replaced by a compressed spring 923 . In addition, in some embodiments, a force applying unit other than the compression springs 913, 923 may be used to apply force to the arm. In this regard, numerous modification examples are conceivable, and thus an excessive description will be omitted.

The first slider clamping part 910 and the second slider clamping part 920 can be lifted up and down by the first and second lifting tools 918 and 928 . The first slider clamping portion 910 is configured to be pivotable within a range of 90° relative to the first lifting tool 918 . The second slider clamping portion 920 is configured to be pivotable within a range of 90° relative to the second lifting tool 928 . The first slider clamping portion 910 and the second slider clamping portion 920 can take at least one low position and at least one high position. For example, when the first slider holding part 910 is located at the high position, the slider 180 held by the first slider holding part 910 is placed on the chain conveying path. The same applies to the second slider holding portion 920 .

The first and second elevating tools 918 and 928 are, for example, electric cylinders capable of controlling the position of the tip of the rod with high precision. The electric cylinder has a built-in stepper motor. By appropriately setting the polarity (+ or -) and the number of pulses supplied to the stepping motor, it is possible to precisely control the position of the tip of the rod. In other embodiments, the first and second lifting means 918, 928 are air cylinders or oil cylinders. In other embodiments, the first and second lifting means 918, 928 are linear actuators other than electric cylinders.

The first slider clamping part 910 and the second slider clamping part 920 are installed on the common substrate 930 by means of the first and second lifting tools 918 and 928 respectively. A substrate elevating tool 960 for elevating the substrate 930 is provided below the substrate 930 . The base plate 930 can take at least one elevated position and at least one low position. In some cases, the slider 180 is placed in the chain conveying path when the base plate 930 is in the high position and the slider clamping portion is in the high position. In some cases, when the substrate 930 is in the low position and the slider holding part is in the low position, the slider holding part can receive the supply of the slider 180 .

As can be seen from the illustration example in FIG. 3 , the first slider gripping portion 910 , the second slider gripping portion 920 , and the base plate 930 can move in the left-right direction away from the chain conveyance path. For example, the base plate 930 is provided so as to be movable on one or more guide rails extending in the left-right direction (not shown). In other cases, the base plate 930 is set longer in the left-right direction, and the first slider clamping portion 910 and the second slider clamping portion 920 can move on the guide rails on the base plate 930 . In the case of FIG. 3 , the substrate 930 may reciprocate between a first position shown by a dotted line and a second position shown by a solid line. The first position is a position directly below the chain conveyance path. The second position is a position obtained by shifting the first position in the left-right direction.

Hereinafter, referring to FIG. 3 to FIG. 8 etc., the structure which supplies a slider toward a chain conveyance path will be mainly demonstrated. As shown in FIG.3 and FIG.4, the apparatus 900 has the slider supply part 980 which accumulates and supplies a slider, and the transfer apparatus 970 for transferring a slider. The sliders stored in the slider supply part 980 are moved to the slider holding part by the transfer device 970 . Although one transfer device 970 is used in the illustrated example, two or more transfer devices may be used in other examples.

As shown in FIG. 5 , the slider supply unit 980 includes a moving path 981 for the slider 180 . In addition, the slider supply part 980 may include a vibratory part feeder. The vibratory parts feeder includes a mechanism for moving a slider along a travel path 981 based on controlled vibrations. The detailed structure and operation of the vibratory parts feeder can be understood from the patent gazette disclosed by the applicant.

The movement path 981 is a flat plate that has a downward slope on which the connecting column 185 of the slider 180 slides, and is erected along the vertical direction. The lower inclined surface is oriented to intersect the vertical direction with an appropriate inclination. When the slider 180 moves on the moving path 981, the connecting column 185 of the slider 180 is in contact with the lower inclined surface of the flat panel, an upper wing 183 is arranged on one wall side of the flat panel, and a lower wing 184 is arranged on the other wall side of the flat panel. .

A passage control unit 985 for selectively passing one slider 180 is provided at a terminal portion of the movement path 981 . The pass control part 985 includes a contact part that contacts the slider 180 and a drive part that displaces the contact part in the vertical direction. For example, the control part 985 includes a buffer 985k as a contact part and a linear actuator as a driving part. While the shock absorber 985k of the control part 985 ascends and separates from the slider 180, the slider 180 is allowed to pass. The impact given to the slider 180 is reduced by using the shock absorber 985k.

An elevating tool 986 is disposed adjacent to the terminal portion of the movement path 981 , whereby one slider 180 selectively supplied by the control unit 985 is selectively elevated. The elevating tool 986 has a first flat plate arranged adjacent to the flat plate of the movement path 981 , and a second flat plate arranged at a distance equal to the connecting column 185 of the slider 180 from the first flat plate.

The first flat plate and the second flat plate are arranged, for example, on the movable part of the linear actuator, for example, on the front end of the rod of the electric cylinder. When the rod end of the electric cylinder of the control unit 985 is located at the retracted position, the rod end of the electric cylinder of the elevating tool 986 is also located at the retracted position. One slider 180 passing through the control unit 985 passing through the movement path 981 falls between the first and second flat plates of the elevating tool 986 and is supported at the end of the rod provided with the first and second flat plates. When the lifting tool 986 works, as shown in FIG. 5( a ) to FIG. 5 ( b ), the slider 180 is lifted vertically upward.

As shown in FIG. 6, the transfer apparatus 970 can transfer the slider 180 raised as mentioned above. The transfer device 970 may include, for example, a commercially available adsorption device. 6( a ) and FIG. 6( b ), the suction part 971 of the transfer device 970 suctions the lower surface of the lower blade 184 , and then moves up with the suction part 971 suctioning the slider 180 . As can be seen from FIG. 7 , the transfer device 970 can operate so as to press-fit the handle mounting column 186 of the slider 180 between the pair of arms of the slider gripping portion. The action principle of the adsorption device belongs to the category of technical common sense.

As shown in FIG. 4 and FIG. 7 , the first slider gripping portion 910 can take a lying posture perpendicular to the vertical direction and an inverted posture parallel to the vertical direction by power from a driving source (not shown) such as a motor. The first slider gripping unit 910 receives the supply of the slider 180 in the lying posture, and arranges the gripped slider 180 on the chain conveyance path in the inverted posture. The same applies to the second slider holding portion 920 . As shown in FIG. 8( a ) and FIG. 8 ( b ), in order to dispose the slider 180 clamped by the slider clamping part in the standing posture to the chain conveyance path, the board lifting tool 960 can move from a low position toward High position rises.

Provided as above, the slider 180 is conveyed from the slider supply part 980 to the chain conveyance path. In addition, after the slider 180 passes through the zipper chain 100, the substrate elevating tool 960 returns the substrate 930 to the lower position. The slider holding portion also returns to the low position. The slider clamping part returns to the lodging posture. The slider grip moves to the position shown by the solid line in FIG. 3 . As described with reference to FIGS. 3 to 6 , the slider is moved to the slider holding portion.

When the slider 180 is arranged on the chain conveying path, the insertion device 30 drives and conveys the fastener chain 100 from the upstream side toward the downstream side in the chain conveying direction, and the core thread of the fastener tape 110 and the fastener elements 120 are inserted during this process. Go to the pull head 180.

As can be seen from FIG. 10 , the first clamping member 10 and the second clamping member 20 are respectively provided with a pivotally supported base end portion and a front end portion provided with a clamping portion for clamping the zipper tape 110 . , and the top view is an L-shaped component. The clamping portion is provided so as to protrude inwardly in the left-right direction. In other examples, each clip is formed in a shape other than the L-shape.

The first clip 10 and the second clip 20 are respectively configured to clip or clip the fastener tape 110 . As shown in FIG. 11 , the first clamping member 10 and its clamping portion include an upper portion 10m and a lower portion 10n, and are configured to be adjustable in vertical intervals between the upper portion 10m and the lower portion 10n. When the vertical interval between the upper part 10m and the lower part 10n is minimum, the fastener tape 110 is sandwiched between both. When the vertical distance between the upper part 10m and the lower part 10n is the largest, the fastener tape 110 will not be caught between the two. The second clamping member 20 also includes an upper part 20m and a lower part 20n, and is configured to be able to adjust the vertical distance between the upper part 20m and the lower part 20n.

Regarding the control of the up-and-down distance between the upper part 10m and the lower part 10n of the first clamping part 10, for example, a permanent magnet can be set on one side of the upper part 10m and the lower part 10n, and an electromagnet can be set on the other side, and the upper part can be controlled by the energization control of the electromagnet. Opening and closing of 10m and lower 10n. The same applies to the second holder 20 . Other on-off control methods may also be used.

As shown in FIG. 10 , the first clamping member 10 and the second clamping member 20 respectively have a first pressed portion 18 and a second pressed portion protruding inwardly in the left-right direction between the front end and the base end. Section 28. The first pushed portion 18 and the second pushed portion 28 are portions pushed by the pusher 40 . The first pressed portion 18 and the second pressed portion 28 respectively include surfaces 16 and 26 that intersect non-perpendicularly with the moving direction of the pusher 40 by the drive mechanism 50 .

The surface 16 of the first pressed portion 18 and the surface 26 of the second pressed portion 28 are inclined surfaces that are separated from the pusher 40 as they extend inwardly in the left-right direction.

The pushing member 40 can move along the chain conveying direction on the insertion device 30 according to the driving of the driving mechanism 50 . When the pusher 40 moves toward the upstream side in the chain conveying direction, the pusher 40 contacts the first pushed portion 18 and contacts the second pushed portion 28 . When the pushing member 40 further moves upstream in the chain conveying direction, the first pushed portion 18 is pushed away toward the outside in the left-right direction, and the first clamping member 10 pivots toward the outside in the left-right direction. Likewise, the second pushed portion 28 is pushed away toward the outside in the left-right direction, and the second clamping member 20 pivots toward the outside in the left-right direction. In this way, the left-right interval between the clamping portion of the first clamping member 10 and the clamping portion of the second clamping member 20 increases.

When the push member 40 moves toward the downstream side in the chain conveyance direction, the first clamping member 10 pivots inwardly in the left-right direction according to the biasing force received by an urging member such as a spring not shown in the figure. The second holder 20 pivots inwardly in the left-right direction in response to a biasing force received from an urging member such as a spring not shown. When the pushing member 40 is no longer in contact with the first pushed part 18 and the second pushed part 28, the first clamping part 10 and the second clamping part 20 return to the initial position, and the first clamping part 10 The left-right distance between the clamping portion of the second clamping member 20 and the clamping portion of the second clamping member 20 returns to the initial value.

In some embodiments, the pushing member 40 is configured to be movable in a direction other than the chain conveying direction. For example, in other embodiments, the pushing member 40 is configured to be movable along the vertical direction, and the clamping portion and the second clamping portion of the first clamping member 10 are adjusted according to the vertical movement of the pushing member 40 . The left and right spacing of the clamping part of the piece 20.

In the illustrated example of FIG. 10 , the pusher 40 includes a first rotating body 41 arranged to be able to contact the first pressed portion 18 and a second rotating body arranged to be able to contact the second pushed portion 28 . 42. By arranging the first rotating body 41 and the second rotating body 42, it is possible to avoid a strong collision between the pushing member 40 and the pushed part, and it is possible to ensure that each clamping member pivots toward the left-right direction outer side and toward the left-right direction more smoothly. direction inward pivoting.

Also, the pusher 40 shown in FIG. 10 includes a base 48 extending in the left-right direction, a first arm 43 provided at the left end of the base 48 , and a second arm 45 provided at the right end of the base 48 . The first rotating body 41 is rotatably provided at the front end portion of the first arm 43 . The second rotating body 42 is rotatably provided at the front end portion of the second arm 45 .

The drive mechanism 50 is any device capable of moving the pusher 40 . In one example, the driving mechanism 50 includes an electric cylinder as a linear actuator, and a pusher 40 is installed at the front end of the cylinder rod. In other examples, the drive mechanism 50 includes a ball screw and a motor for rotating the screw shaft of the ball screw as a linear actuator.

Referring to FIG. 9 and FIG. 12 , the process of the slider 180 passing through the zipper chain 100 will be described in detail. First, the ends 118 of the fastener tapes 110 of the zipper chain 100 are clamped by the first clamping part 10 and the second clamping part 20 . In some cases, the zipper chain 100 is severed by the cutting mechanism 940 to form the end 118 of the zipper tape 110 .

Between time t0 and time t1 shown in FIG. 12 , the insertion device 30 moves downstream in the chain conveyance direction in a state where the fastener tape 110 is clamped by the first clamping tool 10 and the second clamping tool 20 . In some cases, the downstream movement of the insertion device 30 is controlled with high precision by supplying pulses to the stepping motor. According to the downstream movement of the insertion device 30, the end portion 118 of each fastener tape 110, for example, the core wires of the opposite side edge portions of the fastener tape 110 pass through the upper flap of the first slider 181 held by the first slider holding portion 910. 183 and the lower wing plate 184.

When time t1 in FIG. 12 is reached, the core wire of each fastener tape 110 is in a state about to collide with the connecting post 185 of the first slider 181 . At time t1 , the insertion device 30 starts to increase the left-right distance between the clamping part of the first clamping part 10 and the clamping part of the second clamping part 20 . In some cases, the drive mechanism 50 moves the pusher 40 toward the upstream side in the chain conveyance direction according to the supply pulses to the stepping motor of the drive mechanism 50 . According to the movement of the pushing member 40 , the first clamping member 10 pivots outward in the left-right direction, and the second clamping member 20 pivots outward in the left-right direction. As a result, the left-to-right interval between the clamping portion of the first clamping member 10 and the clamping portion of the second clamping member 20 increases. The increase of the left-right distance between the clamping part of the first clamping part 10 and the clamping part of the second clamping part 20 means that the zipper tape 110 clamped by the first clamping part 10 is different from that clamped by the second clamping part 20 . The increase of the left-right interval of the fastener tape 110 held, in short, means the increase of the left-right interval of the left and right core threads, or the increase of the left-right interval of the subsequent left and right fastener element rows. In this way, the left and right core wires and the subsequent element rows can smoothly travel in the left and right spaces of the connecting column 185 of the first slider 181 .

At time t2, the movement of the pusher 40 stops, and the left-right distance between the clamping portion of the first clamping member 10 and the clamping portion of the second clamping member 20 is kept constant. At time t3, the left-right distance between the clamping portion of the first clamping member 10 and the clamping portion of the second clamping member 20 starts to decrease. Between time t2 and time t3, the core thread of each fastener tape 110 enters into the left-right space of the connection column 185 of the 2nd slider 182 clamped by the 2nd slider clamping part 920. As shown in FIG. In addition, this space is also called the front opening of the slider 180 . The slider 180 has two front openings on the left and right of the connecting column 185 . The slider 180 has a rear opening on the opposite side of the front opening.

The left and right fastener stringers 170 are closed by the passing of the second slider 182, and the left and right element rows L120 are in a meshed state. When the left and right element rows L120 mesh, the left-right interval of the left-right fastener tape 110 decreases. Therefore, at time t3, the insertion device 30 starts to reduce the left-right distance between the clamping portion of the first clamping member 10 and the clamping portion of the second clamping member 20 in order to ensure or promote the reduction of the left-right interval of the fastener tape 110 . Work at intervals. The drive mechanism 50 moves the pusher 40 toward the upstream side in the chain conveyance direction. The first clamping part 10 pivots inwardly in the left-right direction, and the second clamping part 20 pivots inwardly in the left-right direction. In this way, the left-right distance between the clamping portion of the first clamping component 10 and the clamping portion of the second clamping component 20 returns to the initial value, thereby ensuring that the left and right zipper elements 120 are well engaged with each other. At time t4, the movement of the pusher 40 stops, and the left-right distance between the clamping portion of the first clamping member 10 and the clamping portion of the second clamping member 20 is kept constant.

The left-right interval between time t0 and time t1 coincides with the left-right interval after time t4. The change rate of the left-right interval between time t1 and time t2 matches the change rate of the left-right interval between time t3 and time t4.

As shown in FIG. 9 , the clamping portion of the first clamping tool 10 clamping the fastener tape 110 moves along the movement locus L1. The clamping portion of the second clamping member 20 clamping the fastener tape 110 moves along the movement locus L2. The core thread of the fastener stringer 170 held by the first holder 10 and the fastener element 120 move along the movement locus L1'. The core wire of the fastener stringer 170 held by the second holder 20 and the fastener element 120 move along the movement locus L2'.

After the zipper chain 100 passes through the first slider 181, as shown in FIG. 13, the device 900 shown in FIG. Displacement of the zipper chain 100 passing between the first slider 181 and the second slider 182 is well suppressed.

After the fastener chain 100 passes through the first slider 181 and the second slider 182 , the device 900 shown in FIG. 1 lowers the cutting mechanism 940 for cutting the fastener chain 100 at the partition 130 . The cutting mechanism 940 may include, for example, a cutting knife with a sharp edge. The device 900 may include a cutting table provided below the zipper chain 100 when the cutting mechanism 940 cuts the zipper chain 100 .

In some cases, the pressing member 950 or the cutting mechanism 940 is provided on the movable part of the linear actuator, such as the front end of the rod of the electric cylinder, and is controlled to work at an appropriate timing. The downstream fastener chain 100 separated from the upstream fastener chain 100 by the cutting mechanism 940 falls along the inclined plate 990 for slider collection by its own weight, and falls into a collection box not shown.

It can be seen from the above description that the device 900 includes a plurality of linear actuators. In some cases, apparatus 900 may include more than one logic circuit or more than one computer for controlling multiple linear actuators.

In some cases, the device 900 includes a computer including at least a storage unit and a CPU (Central Processing Unit: central processing unit). A control value set (Control value set) classified according to the size of the fastener chain and the slider is stored in the storage unit of the computer. In some cases, a first control value included in the set of control values is used for movement control of insertion device 30. The second control value contained in the control value set is used for the movement control of the push member 40 . In some cases, the first and second control values are binary control values, which can be H level (High level) (=1) and L level (Low level) (=0).

When a slider of a different size is inserted into a fastener chain of a different size, the locus of movement shown in FIG. 12 will change. For example, compared with the case of inserting a small-sized slider into a small-sized zipper chain, when a large-sized slider is inserted into a large-sized zipper chain, it is required to increase the interval between time t1 and time t2 in FIG. 12 and The interval between time t3 and time t4.

In some cases, the moving speed of the pusher 40 by the driving mechanism 50 and the moving speed of the insertion device 30 by the driving mechanism 5 are fixed. In this case, by appropriately adjusting the timing at which the second control value changes from L level to H level, the interval between time t1 and time t2 and the interval between time t3 and time t4 in FIG. 12 can be adjusted. The case shown in FIG. 12 includes a first control value that does not change over time and a second control value that changes over time.

In some cases, the computer can also adjust the moving speed of the pushing member 40 based on the driving mechanism 50 and the moving speed of the insertion device 30 based on the driving mechanism 5 . In addition, in some cases, a driver is provided between the computer and the driving mechanism 5 . Likewise, a driver is provided between the computer and the drive mechanism 50 .
