Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a locking piece attachment device used for attaching a price tag to a product or for connecting two or more articles.

[Conventional technology]

The locking piece is a so-called "tag pin", and as shown in FIGS. 1 and 2, it consists of a head 1 for attaching a price tag, a filament 3 extending in a T shape from the center of the head 1, and a filament 3 extending from the center of the head 1 in a T-shape. A horizontal bar 2 fixed perpendicularly to the end of 3 and penetrating clothing, etc.
This locking piece t consisting of three parts is
It is planted in a comb shape on the connecting rod 5 via the connecting portion 4, and is integrally formed as a locking piece assembly T from a synthetic resin such as nylon or polypropylene.

The reason why this locking piece assembly T is used is that it is easy to produce, and it is easy to perform various processes such as packaging, transportation, and driving.
The book locking piece t is planted.

For this locking piece assembly T, the interval l between the locking pieces t on the connecting rod 5 is normally arranged at around 2 mm for mold manufacturing and for loading and driving into the mounting device. .

As shown in FIG. 3, the mounting device A for driving the locking piece t is provided with a lever 11 swingably provided on the grip portion 10a of the main body 10, and the movement of the lever 11 is transmitted to the intermediate lever 12 and the slider 13. Push rod 1
4 toward the horizontally grooved hollow needle 15 attached to the tip of the main body 10, and then move the horizontal bar 2 of one locking piece t located at the rear of the hollow needle 15 to the hollow needle 15. , and feed it to the back side of clothing etc. through which this hollow needle 15 has penetrated, and then remove the locking piece t.
to fix the price tag to clothing, etc. A guide groove 16 is provided in the front part of this attachment device A, and the connecting rod 5 is inserted into the guide groove 16 and is fed downward when the horizontal rod 2 of one locking piece t passes through the hollow needle 15. In this step, the connecting portion 4 is cut by the cutting blade 17.

As shown in FIG. 4, the feeding mechanism of the conventional mounting device A is such that a gear 18 is engaged between the connecting portions 4 that are set on the connecting rod 5, and as the lever 11 is grasped and swung, the slide bar 19 is moved. is moved, and a ratchet pawl is driven by a cam mechanism (not shown), and the gear 18 is intermittently rotated tooth by tooth to send the locking piece.

As mentioned above, the interval l (pitch) between the locking pieces t on the connecting rod 5 constituting one set of locking piece assemblies T is approximately 2.
mm, and therefore the interval between the connecting portions 4 is also approximately 2 mm.

The spacing l between the locking pieces t planted on the connecting rod 5 is set to a certain value for the above reasons, but recently it has been made more compact to improve productivity and ease of handling. There has been an increasing need to change this interval l in order to increase the density. More specifically, reducing the heat capacity by making the mold smaller is not only advantageous in terms of temperature control, but also in that the mold can be manufactured at a lower cost.

In this way, when the interval l between the locking pieces t, that is, the interval between the connecting parts 4 changes, it is impossible to feed with the feeding mechanism of the mounting device that uses a conventional feeding gear, in other words, the feeding pitch is constant. This caused a problem in which jamming occurred at the entrance of the hollow needle, making it impossible to drive the needle.

That is, in the conventional mounting device, since the gear 18 is meshed with the connecting portion 4 as shown in FIG. 4, if the spacing (pitch) of the connecting portion 4 is different, it will naturally not match the pitch of the gear 18. Therefore, if the connecting parts 4 are a collection of locking pieces with a spacing of around 2 mm, they can be loaded into a conventional attachment device and locked to an article, but locks with connecting parts 4 of other pitches can be used. The stopper assembly T had a drawback that it could not be fed.

Another problem is that the connecting rods 5 after the locking pieces t have been cut are sequentially fed out from the lower end opening of the connecting rod loading guide groove 16 provided in the mounting device A.

The connecting rod 5 has a comb-shaped connecting portion 4 that has been cut off and has a sharp tip, and is easily caught on clothes, etc. to which price tags are being fixed. When this happens, there is a problem in that the price tag fixing work must be temporarily stopped and the connecting rod 5 must be cut with a cutter, scissors, or the like.

[Problem to be solved by the invention]

The present invention was made in view of the above-mentioned problems, particularly the latter problem, and allows the portion of the connecting rod where the remains of the connecting portion remain to be removed manually without using cutting tools such as cutters or scissors. The purpose is to make it so that it can be easily torn to pieces.

[Means to solve the problem]

That is, the locking piece attaching device according to the present invention attaches the locking piece through the connecting part into the horizontally grooved hollow needle attached to the distal end of the main body by the pushing rod which is moved forward by the pulling operation of the lever pivotally supported on the main body. In a locking piece attachment device in which a horizontal bar of a locking piece attached to a connecting rod is pushed in, a feed piece is attached to a cam plate disposed behind the guide groove so as to be movable up and down along the guide groove. A link piece for rotating the feed piece is pivotally supported on the feed piece, and a cutting blade is fixed to the lower part of the feed piece facing the connecting rod in the guide groove. A presser piece is provided on the head, which engages with a pin fixed to the lower part of the link piece and forcibly pulls down the link piece to form a cut groove formed by the cutting blade on the connecting rod. It is.

[Effect]

When the lever is pulled, the link piece is forcibly pulled down by the presser piece provided on the head of the lever, which causes the feed piece to rotate and the cutting blade attached to the feed piece to connect to the connecting rod. The cutting blade bites into the connecting rod to form a cutting groove.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 5 is a front view showing the lever in a released state, FIG. 6 is a front view showing the lever in a half-grip state, and FIG. 7 is a front view showing the lever in the deepest grip state.

(Latching piece feeding state) As shown in FIG.
A recess 20 is provided on the side of the recess 20, and a cam plate 21 is housed in the recess 20 so as to be slidable vertically (along the direction of movement of the connecting rod 5). A cam guide surface 21a is obliquely formed on the lower side of the cam plate 21, and a contact portion 19a formed at the tip of the slide bar 19 comes into contact with the cam guide surface 21a.

This slide bar 19 is provided with a protrusion 19b, which allows the lever 11 to be gripped and the intermediate lever 1 to be gripped.
When lever 2 rotates in the direction of arrow A, this intermediate lever 1
An auxiliary intermediate lever 22 connected to the protrusion 1
9b, and as a result, the slide bar 19 advances and the vertical cam plate 21 is raised by the contact portion 19a at the tip of the slide bar 19. When the slide bar 19 is pushed in the farthest position, the state shown in FIG. 6 is reached. .

Note that the auxiliary intermediate lever 22 is connected to the cam plate 21.
When the slide bar 19 is at the highest position, it comes off the protrusion 19b, so the slide bar 19 does not move forward any further.
The cam plate 21 remains at the top.

A free end 23a of a stepped elastic piece 23 made of phosphor bronze is located above the cam plate 21, and as shown in FIG. This cam plate 21 contacts the bottom of the recess 20. Then, since the free end 23a of the elastic piece 23 contacts and presses the cam portion formed at the top of the feed piece 25, the feed piece 25
is rotated counterclockwise, the cutting blade 25b provided at the extended end of this feeding piece 25 comes out from the side surface of the connecting rod 5, and the deep cutting groove 5a formed in the forward feeding process is exposed on this connecting rod 5. do.

(Step of raising the feed piece) Next, when the lever 11 is grasped, the slide bar 1
9 moves forward and contacts the cam guide surface 21a of the cam plate 21, pushing the cam plate 21 up as shown in FIG. When the cam plate 21 is raised in this manner, the elastic piece 23 is lifted, and the elastic piece 23 stores elastic energy for pushing down the cam plate 21 and rotating the feed piece 25 counterclockwise.

Further, a feed piece 25 is provided on the cam plate 21 so as to be able to freely swing around a shaft 25a provided at the upper part of the feed piece 25, and an upper end portion of a link piece 26 for swinging the feed piece 25 is attached to the shaft. 26a. A slit 26b is formed in the middle part of this link piece 26, and this slit 26
A pin 21b protruding from the cam plate 21 is engaged with the pin 21b to prevent the link piece 26 from shifting laterally.

Further, a pin 26c is protruded from the lower end of the link piece 26, and when the lever 11 is gripped, that is, when the lever 11 is rotated in the direction of arrow B shown in FIG. The presser piece 11b protruding from the upper end of the link piece 11 contacts the pin 26c and presses down the link piece 26. As a result, the feed piece 25
rotates about the shaft 25a in a direction approaching the connecting rod 5, that is, clockwise.

The auxiliary intermediate lever 22 is swingably provided on the main body 10 by a shaft 22a, and a pin 22b is protruded from the intermediate portion of the auxiliary intermediate lever 22. 1
2c, and rotates as the intermediate lever 12 rotates.

(Process of driving the locking piece) When the lever 11 is squeezed, the locking piece assembly T
The locking piece t of the book is struck into a product such as clothing, and this final state is the state shown in FIG.

Immediately before reaching this state, the cam plate 21 is pushed up to the uppermost position by the slide bar 19, and the holding piece 11b of the lever 11 connects to the pin 26c of the link piece 26 to push the link piece 26 down.

Then, the feed piece 25 rotates (clockwise) toward the connecting rod 5 using the shaft 25a as a fulcrum, and the cutting blade 25b provided at its extended end sharply bites into the connecting rod 5 to cut the cut groove 5a. to engrave.

Note that since the cam plate 21 is supported by the slide bar 19 at the top and its position is regulated, the feed piece 25 swings around the fixed shaft 25a and cuts into the connecting rod 5. Since the pushing rod 14 enters the hollow needle 15 with the blade 25b being cut, there is no possibility that the locking piece t will be driven in incorrectly.

Note that the cutting blade 25b is a type of cutting blade, and the force that bites into the connecting rod 5 is not a spring force or the like but the force of gripping the lever 11, so the biting is done reliably and deeply, and the connecting rod 5 cannot be manually operated. The cut groove 5a can be cut to such an extent that it can be broken off by cutting.

Simultaneously with the cutting operation of the cutting blade 25, the pushing rod 14 enters into the hollow needle 15 and causes the horizontal bar 2 to enter the back side of the product such as clothing. As described above, when the pushing rod 14 moves forward, the cutting blade 25 is connected to the connecting rod 5.
Since the cutting is started at , the connecting rod 5 does not move up and down, and the horizontal rod 2 can be accurately fed into the hollow needle 15.

(Returning process of the feeding piece) Next, when the grip force on the lever 11 is loosened from the state shown in FIG. 7, the lever 11 and the like instantly return to the state shown in FIG. 5.

In the return process, the intermediate lever 12 rotates clockwise to release the protrusion 19c of the slide bar 19.
When this happens, this slide bar 19 is moved back. In this state, since the slide bar 19 has come out from below the cam plate 21, the cam plate 21 is lowered by the restoring elastic force of the elastic piece 23 from the state shown in FIG. 7 to the state shown in FIG. 5.

At this time, the blade 25b of the feed piece 25 remains bitten into the side surface of the connecting rod 5, so the connecting rod 5 is pulled down by the feed piece 25 that descends together with the cam plate 21, pushing down the connecting rod 5 and moving to the next Horizontal bar 2 of locking piece t
is aligned with the axis of the hollow needle 15 to prepare for driving.

Although details are not shown, the hollow needle 15
A notch is provided near the entrance of the locking piece t to accommodate about half of the front part of the horizontal bar 2 of the locking piece t, and the remaining part is supported by a guide part provided on the main body. In this state, the downward movement of the feed piece 25, cam plate 21, link piece 26, and locking piece assembly T is stopped, and finally the state shown in FIG. 5 is reached.

When the lever 11 is squeezed again from this state, the lever 11 rotates in the direction of arrow B shown in FIG. intermediate lever 1
2, the slider 13 moves forward and the slide bar 19 engages with the auxiliary intermediate lever 22.
moves forward, pushes up the cam plate 21, and enters the locking piece feeding state.

Then, the connecting rod 5 is pulled down again until the horizontal rod 2 reaches the next driving position.

When the above-mentioned operation is repeated, the locking piece t is cut from the locking piece assembly T and the remaining connecting rods 5 are sequentially fed out from the lower end opening of the guide groove 16.
Since this has grooves 5a formed by cutting blades 25b at appropriate pitches, the connecting rod 5 protruding from the main body can be torn off when it reaches an appropriate length.

In the above embodiment, an example of a device was shown in which the slide bar 19 was advanced by the auxiliary intermediate lever 22 to raise the cam plate 21, but the slide bar 1
9 contact portion 19a and cam guide surface 21 of cam plate 21
By appropriately setting the relationship with a, the auxiliary intermediate lever 22 can be omitted, and the cam plate 21 can be raised by directly advancing the slide bar 19 using the intermediate lever 12.

〔Effect of the invention〕

As described above, the present invention pivots the feed piece in a swingable manner on a cam plate which is disposed behind the guide groove of the locking piece attachment device so as to be able to move up and down along the guide groove. A link piece for rotating the feed piece is pivotally supported, a cutting blade is fixed to the lower part of the feed piece facing the connecting rod in the guide groove, and a pin is fixed to the head of the lever at the lower part of the link piece. Since the connecting rod is provided with a presser piece that engages with and forcibly pulls down the link piece to form a groove formed by the cutting blade, the portion of the connecting rod where the remains of the connecting portion remain can be removed with cutters or scissors. It can be easily torn into pieces by hand without using cutting tools such as.

Furthermore, since it is the force of grasping the lever that causes the cutting blade to bite into the connecting rod, the cutting groove can be reliably provided.
