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.

[Prior art]

The locking piece is a so-called "tag pin", and as shown in FIGS. 1 and 2, it is composed of a head 1 for attaching a price tag, a filament 3, and a horizontal bar 2 that passes through clothing, etc. The locking piece T consisting of these three parts is planted in a comb shape on the connecting rod 5 via the connecting part 4, and is integrally molded 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.
20 to 50 locking pieces t are planted. The locking piece assembly T has a spacing l between the locking pieces t on the connecting rod 5 due to mold manufacturing and loading and driving into the mounting device.
The normal one is arranged around 2mm.

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 controlled by the intermediate bar 1.
2. Transmit the message to the slider 13 to move the push rod 14 toward the horizontally grooved hollow needle 15.
Push the horizontal bar 2 of one locking piece t located at the rear of the hollow needle 15 into the hollow needle 15.
The price tag is fed to the back side of the clothing, etc. through which the tag is penetrated, and the price tag is fixed to the clothing, etc. using the locking piece (t). A guide groove 16 is provided at the front of this attachment device A, and the connecting rod 5 is inserted into this groove and the horizontal rod 2 of one locking piece t passes through the hollow needle 15 while being fed downward. In this case, 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) to intermittently rotate the gear 18 one tooth at a time to send the locking piece.

As mentioned above, the interval l between the locking pieces t on the connecting rod 5 is about 2 mm, and therefore the interval between the connecting parts 4 is also about 2 mm.
mm.

Although the interval 1 between the locking pieces t planted on the connecting rod 5 is set to a certain value for the above-mentioned reason, there has recently been an increasing need to change this interval 1. More specifically, making the mold smaller and having a smaller heat capacity is not only advantageous in terms of thermoeconomics, but also has the advantage that the mold can be manufactured at low cost.

Further, in the case of a locking piece assembly T having a significantly long filament portion, it is necessary to further increase the interval 1 between the locking pieces t.

When the distance of the connecting portion 4 changes as described above, a problem arises in the feeding mechanism of the mounting device. That is, in the conventional mounting device, as shown in FIG.
Since the pitch of 8 is meshed with the connecting portion 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 locking piece assembly has a spacing of about 2 mm between the connecting parts 4,
Although it can be loaded into a conventional attachment device and locked to an article, locking piece assemblies T having connecting portions 4 of other pitches have the disadvantage that they cannot be fed.

By the way, when developing a feeding mechanism for a locking piece assembly in place of the above-mentioned gear, in order not to waste locking pieces, the locking pieces should be fed until the last one of the locking pieces is fed to the front surface of the hollow needle. A feeding mechanism is required that can feed the aggregate into the guide groove.

[Purpose of the invention]

Therefore, in order to avoid wasting the locking pieces, the present invention provides a feeding mechanism that can feed the locking piece assembly into the guide groove until the last locking piece is supplied to the front surface of the hollow needle. An object of the present invention is to provide a locking piece attachment device equipped with the following.

[Structure of the invention]

The present invention has been made to achieve the above object, and includes rotatably providing a friction wheel that comes into contact with the connecting portion of the locking piece assembly behind the guide groove in which the locking piece assembly is installed. The present invention is characterized in that a support plate is swingably attached to the friction wheel, and a sending piece having a protrusion that engages with the friction wheel is swingably attached to the support plate.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 5 is a front view of the main parts of the locking piece attaching device of the present invention, showing the state during the driving operation of the locking piece, and FIG. 6 is a front view similar to FIG. FIG. 7 is an exploded perspective view of a friction wheel, a support plate, and a feeding piece that constitute the main parts of the locking piece attaching device of the present invention. In FIGS. 5 and 6, the same components as those shown in FIG. 3 are denoted by the same reference numerals, and the explanation thereof will be omitted.

Guide groove 16 provided in the front part of the pistol-shaped main body 10
A friction wheel 22 is rotatably provided on the side of the connecting rod 5, and the friction wheel 22 makes contact with the connecting portion 4 installed on the connecting rod 5 and sends the connecting rod 5 by the friction generated by this contact. The outer periphery of this friction wheel 22 is provided with teeth that are narrower than the pitch of the connecting portion 4. Note that instead of these teeth, an oblique groove formed by knurling may be used. The friction wheel of the present invention is not limited to a wheel with fine teeth carved therein or a groove formed by knurling as described above, but a wheel with rubber or the like having a large coefficient of friction affixed thereto, or a wheel made entirely of rubber or the like. Including those who did. Therefore, there is no problem even if the pitch of the connecting portion 4 is changed.

Further, a support plate 24 is swingably provided coaxially with the friction wheel 22. A feed piece 25 is swingably provided on one side of the support plate 24 (on the right side in the drawing) via a pin 24a protruding from an intermediate position on the side. One side of the upper part of the sending piece 25 facing the friction wheel 22 is curved along the outer periphery of the friction wheel 22, and the friction wheel 22 is curved along the outer periphery of the friction wheel 22.
A protrusion 25a is provided that engages with the thin teeth of. Further, a slit 24b extending in the vertical direction is provided at the lower part of the support plate 24, and a slit 25b extending in the vertical direction is also provided at the lower part of the sending piece 25. Slit 24b and slit 25b
The slits 24b have substantially the same length in the vertical direction, but the length (width) in the horizontal direction is set larger for the slit 24b. A protrusion 19a protruding from the side surface of the tip of a slide bar 19 that is moved back and forth by the intermediate lever 12 (which is operated by the lever 11) is fitted into the slits 24b and 25b. As a result, the support plate 24 and the sending piece 25 are oscillated.

The reason why the width of the slit 24b is made larger than that of the slit 25b is to allow the sending piece 25 to rotate relative to the supporting piece 24.

Next, the operation of the above device will be explained. When the locking piece driving operation is completed (see FIG. 5), when the grip on the lever 11 is released, the slide bar 19 is moved backward by the intermediate lever 12. As the slide bar 19 retreats, the protrusion 19a comes into contact with one inner surface of the slit 25, and the feed piece 25 touches the pin 2.
4a as a fulcrum, rotates toward the friction wheel 22 side, and the protrusion 25
a engages with the thin teeth of the friction wheel 22, and in this state, the feeding piece 25 and the supporting piece 24 engage with the friction wheel 22.
The friction wheel 22 is rotated in the direction of the arrow a shown in FIG. 6 using the rotation center as a fulcrum, and as a result, the friction wheel 22 rotates in the same direction and sends the connecting rod 5 in the direction of the arrow b shown in the figure.

In this way, the sending piece 25 is rotated about the pin 24a to engage the protrusion 25a with the friction wheel 22, and in this state, the sending piece 25 is rotated about the rotation center of the friction wheel 22, i.e. When the protrusion 25a is moved along the outer circumference of the friction wheel 22, the protrusion 25a engages with the friction wheel 22 without slipping and rotates together with the friction wheel 22. It can be rotated.

When the feeding operation of the connecting rod 5 is finished and the next driving operation is started, the projection 19a comes into contact with the other inner surface of the slit 25b due to the advance of the slide bar 19, and the feeding piece 25 generates friction using the pin 24a as a fulcrum. The protrusion 25b is rotated away from the wheel 22, and the protrusion 25b is removed from the friction wheel 22. In this state, the feed piece 25 is rotated together with the support plate 24 in the opposite direction to the previous direction using the rotation center of the friction wheel 22 as a fulcrum. be moved. Therefore, when entering the next driving operation, the protrusion 25b first comes off from the friction wheel 22, so there is no problem of rotating the friction wheel 22 in the direction opposite to the direction of the arrow a.

Note that in order to engage the protrusion 25a of the feed piece 25 with the thin teeth of the friction wheel 22 and rotate the feed piece 25 about the rotation center of the friction wheel 22, the protrusion 19 is
Although slits 24b and 25b having different widths from a are used, the present invention is not limited to this.

〔Effect of the invention〕

As explained above, the present invention provides a rotatable friction wheel that abuts the connecting portion of the locking piece assembly behind the guide groove in which the locking piece assembly is mounted, and a support plate is attached to the friction wheel. Since the feeding piece having a protrusion that engages with the friction wheel is swingably attached to the support plate, the last one of the locking pieces is attached to the front surface of the hollow needle. The locking piece assembly can be fed into the guide groove until it is fed. Therefore, in the present invention, even the last locking piece in the locking piece assembly is not wasted.

Also, after bringing the protrusion of the feed piece into contact with the friction wheel,
Since the feed piece is rotated using the rotation center of the friction wheel as a fulcrum, the friction wheel can be reliably rotated and the locking piece assembly can be reliably fed.
