A tag attachment apparatus is disclosed that includes a slide for driving a pawl, gear means for driving the slide, and a band lever for driving the gear means.

When the band lever is actuated, the push rod drives the bar portion of the fastener through the needle.

When the band lever is released, spring means return the push rod and cause the toothed member to drive the toothed wheel.

A release control is provided for disengaging the pawl from the teeth of the toothed wheel and withdrawing the fastener assembly from the device.

The present invention particularly relates to an improvement in the tag attachment apparatus according to the above-mentioned US Pat. No. 3,759,435.

In accordance with various embodiments of the invention, the tag attachment apparatus includes:
Gear means consisting of a slotted needle with a side opening, a toothed wheel, a pawl cooperable with the toothed wheel, a push rod, a slide connected to the push rod, and at least one gear segment. an actuator for driving the gear means, and a return spring means, the gear means driving and returning the push rod to actuate the pawl.

In one embodiment, the gear means supports a pair of radially spaced protrusions, and the pawl supports the contact portion.

The protrusion and the contact portion constitute an idle motion.

When the user squeezes the actuator, the gear means rotates and near the end of its rotation, one protrusion drives the contact in one direction to move the pawl from the first position to the second position.

When the user releases the actuator, the return spring means returns the actuator, gear means, push rod, and slide to their respective initial positions, driving the pawl from the second position to the first position to drive the toothed wheel. and then advance the fastener assembly.

In another embodiment, the pawl supports a pair of contact members movable relative thereto.

The gear means supports a pair of radially spaced projections which cooperate alternately with each of the contact members.

The contact members are each individually rotatably mounted on the pawls, with spring means forcing them towards their normal or initial position.

The contact members alternately bend when the projections cooperate with them.

According to one embodiment of the invention, a tag attachment device includes a slotted needle having a side opening, a toothed wheel, a pawl cooperable with the toothed wheel, and a push rod.
The slide includes a knife, an actuator, and gear means coupled to the actuator, the slide having a gear segment cooperable with the gear means.

As the slide moves in one direction, it drives a push rod to separate the bar portion of the fastener from the coupling member of the fastener assembly;
Push the bar portion into the needle such that the filament portion passes through the side opening of the needle.

Movement of the slide also drives the pawl from the first position to the second or ready position.

Return spring means drive the actuator, gear means, slide and push rod to their respective initial positions.

When the actuator is actuated, a spring drives the pawl to the first position, and a protrusion carried by the gear segment cooperates with a contact on the pawl to drive the pawl from the first position to the second position. , thereby advancing the fastener assembly to a position where the bar portion of the next successive fastener is aligned with the needle and push rod.

In another embodiment, the slide is used only to drive the push rod and the fastener assembly is advanced by a simple pawl and ratchet mechanism.

The pawl is mounted on a pivot supported by the plate.

This plate is fixed directly to the band lever, and when the band lever is released, a ratchet wheel, which is fixed coaxially to the feed wheel, is driven by the pawl.

The pawl has an extension or bundle that can be engaged by the pawl to remove the fastener assembly from the device.

Also, in accordance with another embodiment of the invention, a push rod is advanced to push the bar portions of the fastener assembly, thereby separating the bar portions of one fastener from the other portions of the fastener assembly, and The bar portion is moved through the hollow needle such that the filament portion passes through a side slot of the needle.

The pawl moves between a first position and a second position relative to the toothed wheel.

No movement is imparted to the pawl when it moves from the first position to the second position.

However, a spring is used to move the pawl from the second position to the first position and drive the toothed wheel.

Rotation of the toothed wheel advances the fastener assembly to a position where the bar portion of the preceding fastener is aligned with the push rod.

However, the spring is prevented by the latch from moving the pawl from the second position to the first position during part of the operating cycle.

This latch latches the pawl to prevent drive movement.

However, when the push rod is retracted far enough so that the leading spring portion is aligned with the needle, the latch disengages and the spring allows the pawl to move and drive the toothed wheel.

According to another embodiment of the invention, the pawl and push rod are actuated by cooperating gear wheels, one of which has a notch or groove that controls the action of the pawl.

The pawl is movable from a first position to a second position, and the pawl drives the toothed wheel while the pawl returns from the second position to the first position.

A link is movably connected to the pawl and supports a projection received in the groove.

The groove has spaced contact surfaces disposed at opposite ends.

The gears are driven by actuators that can be operated manually.

When the gear having the groove is driven in one direction, near the end of the one-way movement of the gear, the protrusion contacts one of the contact surfaces and moves the pawl from the first position to the second position. urge

When the grooved gear is driven in the opposite direction, near the end of its travel, the protrusion contacts the contact surface at the other end and moves the pawl from the second position to the first position, causing the toothed wheel to move from the second position to the first position. to drive.

When the toothed wheel is driven, the fastener assembly is indexed to bring the leading bar portion into alignment with the hollow needle.

The ends of the groove are oriented with respect to the protrusion so as to travel a suitable distance and not interfere with centering the push rod with the needle hole of the preceding bar portion.

Next, some specific examples of the present invention will be described with reference to the accompanying drawings.

Referring to the embodiments of FIGS. 1-9, a tag attachment apparatus, designated generally at 27, is illustrated.

Device 27 has a body 28 with two body sections 29 and 30.

The body 28 has a guideway 32 adapted to receive a fastener assembly 33 of the type illustrated in FIGS. 4 and 5.
It has a nose section 31 with a.

Fastener assembly 33 includes a plurality of fasteners 34.

Each fastener 34 is comprised of a bar portion 35 and a head or button portion 36 connected by a filament portion 37.

Fasteners 34 are coupled to a common support member or runner 38 by respective coupling members 39.

Guideway 32 is adapted to receive a common carrier member 38, coupling member 39 and bar portion 35, with filament portion 37 extending from the side of device 2T.

1. The nose 31 is equipped with a hollow needle 40 having an elongated slot 41.

Bar portion 35 can pass through a hole or passageway 42 extending through needle 40 .

On the other hand, filament portion 37 passes through or projects through slot 41 .

The needle 40 has a rear cutting edge 43 for cutting the bar portion 35 from its coupling member 39.

Needle 40 has a slot 44 through which bar portion 35 can enter needle 40 .

The actuator, indicated generally at 45, includes a band lever 46 for engagement by a user's finger.

This band lever 46 is rotatably installed relative to the main body 28 by a pin or shaft 45'.

Lever 46 is drivingly connected to gear means, generally indicated at 47, by a link or coupling member 48.

The connecting member 48 is connected to the band lever 46 by means of a pin 48'.
and are respectively pivotably mounted on gear means 47 by means of pins 49.

Gear means 47 consists of a pair of gear segments 50 and 51, each having teeth 52 and 53.

Gear segments 50 and 51 are connected to each body section 29
and 30, and are pivotally mounted on the main body 28 by posts 54 and 55 whose axes are aligned with each other.

The slide, designated generally at 56, has each body section 2
It is guided to slide within guideways or slots 57 and 58 in 9 and 30.

Slide 56 has a plurality of sets of holes 59 for receiving teeth 52 and 53.

The slide 56 therefore comprises a gear section, more particularly a rack that meshes with the gears 50 and 51.

Since a release device or push rod 60 is fixed to the slide 56, when the band lever 46 is manually operated, the slide 5
6 and push rod 60 move as a unit.

Since the push rod 60 is guided by the guide member 60'',
The push rod 60 moves while aligning its axis with the hole 42 of the needle 40.

When the user places the main body 28 in the palm of his/her hand and firmly grasps the band lever 46, the band lever 46 is moved to the pin 45'.
3 in a counterclockwise direction (FIG. 1), thereby rotating gear means 41 counterclockwise and driving slide 56 and push rod 60 to the left. As it moves, it drives the bar portion 35 of the fastener 34 through the needle 40, thereby separating the bar portion 35 from its respective coupling member 39.

The return spring mechanism, indicated generally at 61, includes a cavity 62 formed within the body.

This cavity has a container member 6 housed therein.
3 movements are possible.

The insert member 63 is pivotally connected to the gear segments 50 and 51 by a pin structure indicated at 64.

Inside the cavity 62, one end of the compression spring 61' is connected to the main body 28.
The other end of the spring 61' is pressed against the member 63.

When the band lever 46 is released from being tightly squeezed by the user, the return spring mechanism 61 causes the band lever 46 to

Return to the starting position of each family shown in Figure 1.

Apparatus 27 includes a fastener assembly feeding mechanism, generally designated 65, for feeding fastener assemblies 34 one bar portion 35 at a time into alignment with the axis of bore 42 of needle 40.

The feed mechanism 65 has a toothed wheel 66 fixed to a shaft 61 that is rotatably mounted in a bore 68 in the body section 30 .

A toothed wheel 66 is located in the space between body section 30 and member 69, which is cut away in FIG. 1 but is fully disclosed in U.S. Pat. No. 3,759,435.

The wheel 66 has a plurality of teeth 70 arranged on its circumference that engage the coupling member 39 .

Gear 66 is rotated counterclockwise (FIGS. 1, 6 and 9) by the action of cooperable pawls generally indicated at 11.

The pawl 71 is installed so that it can reciprocate as a whole,
Toothed member T2 with two basic parts, namely teeth T3
and a link or link member 74.

A pin 75 pivotally connects members T2 and 74.

Member 72 is provided with a slot, indicated generally at 76, through which shaft 67 extends.

The member 72 is configured to swing back and forth above the shaft 67 as a result of the movement of the link member γ4.

The teeth 73 are hook-shaped and each time they engage one tooth TO of the toothed wheel 66, causing the wheel 66 to rotate.

Since the thrower 1-76 has a parallel earth wall 77 and a lower wall 78 arranged at an angle with respect to the teeth 73,
Movement of member 72 in one direction causes teeth 73 to disengage from wheel 66, and movement of member T2 in the opposite direction causes teeth 73 to engage wheel 66.

To achieve this cam movement, parallel walls 77 and 78
and tooth 73 form an acute angle A.

When member 72 is moved sufficiently by link member 74, one end of slot-shaped hole 16 contacts shaft 76.

Walls 7T and 78 are at an angle with respect to tooth γ3, so that movement of member 12 in one direction will cause tooth γ3 to disengage from engagement between two adjacent teeth 70, and movement in the opposite direction will cause tooth 1 to move out of engagement between two adjacent teeth 70.
3 engages the wheel 66.

Further movement of member 72 in the direction of engagement of teeth 73 as described above causes wheel 66 to rotate.

A resilient member 19 having a projection or stop 80 is provided on the member 69 to prevent the wheel 66 from rotating as the member 72 swings back and forth relative to the wheel 66.

Stop 80 is located between two adjacent teeth γ0 to prevent rotation of wheel 66 except when wheel 66 is actuated by member γ2 or when fastener assembly 34 is pulled upwardly from guideway 32. I have to.

Link member 74 is supported at its rear end by member 81 which is slidable within cavity 82 of body section 30 .

Member 81 presses link member 74 against protrusion or pin 83 by spring 84 .

The structure described above is identical to that of US Pat. No. 37,594.35, and more detailed structures are described in that US patent.

Referring now to the improvements of the present invention, link member 74 is shown in FIG. 1 as having a single downwardly projecting contact or protrusion 85.

The contact portion 85 has a contact surface or stop surface 86 with which a pin or protrusion 87 connected to the gear segment 51 can cooperate.

In the position shown in FIG.
The contact surface 86 is pressed as a reaction against this.

One end of spring 88 presses against the rear end of link member T4, and the other end of spring 88 presses against body section 30.

In the position shown in FIG. 1, member 72 is in the first position of the actuation sequence, which is the same as the last position of the actuation sequence.

When the actuator 45 is squeezed hard, the gear means 47
Accordingly, projection 87 moves counterclockwise, and during this counterclockwise movement link member 74 moves to the left (FIG. 1) under the biasing action of spring 88.

Link member 74 moves from the position of FIG. 1 through the position of FIG. 9 toward the position of FIG. When stopped, the protrusion 87 stops i]'l1
Do not touch B6.

When the user stops squeezing the actuator 45,
The return spring mechanism 61 rotates the gear means 47 clockwise.

When the protrusion 87 moves and contacts the contact surface 86, the protrusion 87 begins to drive the link member 74 one step to the right against the action of the spring 88.

As gear means 41 approaches the end of its clockwise movement, link member γ4 drives member 72 into position.

In this position, end 90 of slot 16 contacts shaft 67, pivoting member 72 counterclockwise from the position of FIG. 6 to the position of FIG.

Since the link member γ4 continues to be driven to the right by the clockwise rotation of the gear means 4γ and the protrusion 87, the toothed member γ
2 drives wheel 66 counterclockwise.

Counterclockwise rotation of wheel 66 then forces subsequent bar portion 35 into needle hole 42 and end 60' of push rod 60.
align with the axis of

Thus, wheel 66 rotates an angle to move fastener assembly 33 a distance equal to the distance from the centerline of one bar section 35 to the centerline of the next adjacent bar section 35.

Springs 61' and 88 act in opposite directions.

Note that because spring 88 is relatively light and spring 61' is relatively heavy, release of hand lever 46 by the user will overcome the force of spring 88.

Assuming that device 27 is loaded with fastener assembly 33, the operating sequence of device 27 is outlined as follows.

When the user firmly squeezes the actuator 45, the gear means 4
7 rotates counterclockwise (FIG. 1) to drive the slide 56 and push rod 60 1 to the left (FIG. 1).

When the end 60' of the push rod 60 acts on one end of the bar portion 35, the knife 43 cuts the coupling member 39 and the push rod 60
As 0 continues to move, bar portion 35 moves through needle 40.

During counterclockwise rotation of gear means 4γ, link member 74 moves to the left under the action of spring 88, thereby moving member 72 from the position of FIG. 1 to the position of FIG.

When the user releases the grip on the actuator 45, the return spring mechanism 61 drives the gear means 47 clockwise (FIG. 6) to pull the push rod 60 out of the needle 40 and remove the end 6.
0' away from the next bar part 35
can enter the needle through slot 44.

As the clockwise movement continues, the protrusion 87 contacts the contact surface 86 and drives the link member 74 to the right,
This moves member 72 into a position between adjacent teeth of wheel 66 to drive wheel 66 and sequentially advance fastener assembly 33.

Like parts in the embodiments of FIGS. 22 and 23 are designated with the same reference numerals as parts in FIGS. 1-9.

The link members 74g have contact surfaces 152 and 153, respectively.
A pair of spaced apart recesses or notches 150 and 151 are provided.

Spring 1, shown in the drawing as a helical tension spring
54 is connected at one end to a post 155 on link member 14g and at the other end to a pin 156 attached to body section 30.

Spring 154 forces pawl 71 into the position shown.

The latch, indicated generally at 157, has a pair of arms 1
58 and 159.

Arms 158 and 159 have contact surfaces 160 and 161, respectively.

A projection 162 fixed to the gear segment 51 of the gear means 47 is in contact with the contact surface 160 in FIG.

A compression spring 163 housed within a recess 164 in body section 30 urges arm 158 of latch 157.

As shown, spring 163 connects contact surface 160 to protrusion 162.
The arm 159 is slightly separated from the link member 74g at the position shown in FIG.

When the user operates the actuator 45, the gear 47
rotates counterclockwise around the shaft 51, moves the slide 56 and push rod 60 to the left, and presses the bar portion 35.
is separated from its coupling member 39 and each filament portion 37 passes through the slot 41 such that the bar portion 35 moves within the hole 42 of the needle 40.

The counterclockwise rotation of gear 4γ also causes protrusion 162 to move away from contact surface 160, thereby causing arm 159 to rotate about pivot 165 and contact link member 74g of pawl 71 between recesses 150 and 151. Make it.

The gear 47 rotates counterclockwise by a predetermined amount to create a recess 150.
Once inside, protrusion 162 contacts contact surface 152 to move link member 74g to the left and rotate toothed member T2 clockwise (FIG. 22).

Near the end of the leftward movement of link member 74g, recess 151
is in a position to receive the end of arm 159 so that latch 157 can rotate clockwise under the bias of spring 163.

When the user stops squeezing the actuator 45, the return spring mechanism 61 releases the actuator 45, the link 48, and the gear 4.
7. Return the slide 56 and the push rod 60 to their initial positions (FIG. 22), and the spring 154 connects the link member 74g.
Push link member 74g slightly to the right until contact surface 153 of latch 14g contacts contact surface 161 of latch 14γ.

Even if the link member 74g moves slightly, the toothed member 1
2 does not drive toothed wheels.

When the gear 47 rotates clockwise enough so that the protrusion 162 contacts the contact surface 160, the protrusion begins to drive the latch 157 into position.

In that position, contact surface 160 separates from contact surface 153, thereby disengaging latch 157, and spring 154 moves link member 74g to the right such that contact surface 166 of projection 167 on link member 74g disengages stop 169. Contact surface 6
Contact 8.

When the return spring mechanism 61 returns the various components to their initial positions, the latch 157 is again in the initial position shown in FIG. 22.

Latch 157 prevents spring 154 from driving toothed wheel 66 by pawl 71 until near the end of travel of push rod 60.

More specifically, the claw 71 has a push rod 60 that is connected to the bar part 3.
The feed wheel 66 cannot be driven until it leaves the path of No. 5.

In this way, it is possible to prevent the leading bar portion 35 from colliding with the retreating push bar 60.

Spring 154 becomes active before latch 157 is released by projection 162 contacting and driving contact surface 160.

Furthermore, since the gear 47 and the pawl 71 are connected to allow free movement, the protrusion 162 can move a predetermined distance relative to the contact surface 152 without imparting any movement to the link member 74g.

Referring to the specific example of FIGS. 24 and 25, tag attachment device 27H is identical to tag attachment device 27, except as shown in the drawings and described below.

Like parts in the embodiment of FIGS. 24 and 25 are designated with like reference numerals as in the embodiment of FIGS. 1-9.

The gear segment 51 of the gear 47 has a groove or notch 200
is provided, which is arcuate and eccentric with respect to the shaft 54.

Link member 201 is preferably movably connected to link member 74h of pawl 71 by a pin or pivot 202.

Link 201 is shown having a protrusion or pin 203 housed within groove 200.

Groove 200 has spaced apart ends or contact surfaces 2
04 and 205.

When the actuator 45 is actuated, the gear 47 rotates clockwise (FIG. 24), and the push rod moves to the right, causing the cutting edge 43 to separate the bar portions 35 from their respective coupling members 39, thereby forcing the bar portions 35 into the needles 40. during which the filament portion 37 passes through the slot 41.

Near the end of clockwise rotation of gear 47, contact surface 204 contacts protrusion 203, thereby driving the link member one step to the right and rotating toothed member γ2.

The clockwise rotation of the gear 47 is completed, and the actuator 45
is released, the return spring mechanism 61 moves the actuator 4
5. Drive link 48, gear 47 and slide 56 to their initial positions, and near the end of the counterclockwise rotation of gear 47, the protrusion contacts contact surface 205 and drives link member 74h to the left. , thereby rotating the toothed member γ2 clockwise to drive the toothed wheel 66 so that the adjacent next bar portion 35 of each fastener 34 is centered with the hole in the needle 40. .

The spacing and location of the contact surfaces 204 and 205 are such that the push rod 60 is out of the path of travel of the leading bar portion 35 before the leading bar portion 35 is advanced and centered with the hole 42, thereby Push rod 60 with which 35 retreats
The spacing and position should be such as to prevent collisions.

Other embodiments and modifications of the invention will readily suggest themselves to those skilled in the art and are provided without departing from the scope of the invention as set forth in the claims.
