Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hang tag attachment machine for attaching hang tags such as price tags to products.

(Prior art) A tag attaching machine reciprocates a needle with a thread threaded through a hole at its tip, projects the needle toward the front of the machine frame, and pierces the object to be attached, such as cloth. Grasp the tip of the thread and place it there, hook the thread that comes out sideways from the hole of the needle with the thread hook, lift it once, and then pull it back to align the leading and trailing ends of the thread. It held the aligned parts in its beak, formed a knot using a rotating knot mechanism, and attached a tag.

When attaching tags to thin objects, these hang tag attachment machines can easily insert the needle directly into the object without protecting it, but when attaching tags to hard or thick objects, Depending on the attachment, it becomes difficult to insert the needle through the attachment, and if you try to force the needle through the attachment, problems such as needle breakage or bending may occur, making it difficult to attach the tag smoothly. Can not do it.

Therefore, it is necessary to provide a tube needle that covers and protects the needle so that no external force is applied to the needle when piercing a thick object. A horizontal crack including the generatrix opposite the hole of the needle was formed straight from the base end to the tip, and was attached with screws to a predetermined position on the front end plate making up the machine frame.

(Problems to be Solved by the Invention) In the above-mentioned conventional tag attaching machine, the split of the tube needle is oriented horizontally at the base end, so the thread hooked with the thread hook is first lifted from the tip of the needle. There is a problem in that when the thread is lifted up, it comes into contact with the edge of the horizontal crack and is subjected to frictional force, making it difficult to form a knot smoothly afterwards.Also, since the needle is attached with a screw, A drawback is that it is cumbersome to switch between thin and thick objects.

If the upper edge of the crack at the base of the cylindrical needle is removed in order to reduce the frictional force that the thread receives while leaving the horizontally straight crack, the cylindrical needle will not only have insufficient strength, but also be difficult to attach. There is a problem.

In view of such conventional drawbacks, the present invention provides a cylindrical needle that does not increase the frictional force applied to the thread, maintains sufficient strength of the cylindrical needle, and
To provide a hang tag attaching machine that can easily attach and detach a tube needle depending on the thickness, thinness, hardness, and softness of the object to be attached.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a needle having a hole at its tip, through which a thread is inserted, and reciprocates toward an object loading section; A cylindrical needle is attached to a predetermined location on the machine frame to cover and protect the needle that penetrates the object, and a thread is hooked from the tip of the needle to a thread hook formed at the tip.

Hereinafter, the operation of the tag attaching machine according to the above embodiment of the present invention will be explained.

First, the thread T pulled out from the bobbin (not shown) stored in the handle 7c is passed through the needle hole 20a of the needle 20, the needle 20 is attached to a predetermined position, and then the drive lever 11 is closed for the first time. When operated, the needle 20 penetrates the slit 9a of the front end plate 9.
It protrudes from the lower end through hole 9b and is protected by the cylinder needle 10, and at the same time, the clamping plate 46d,
47b diagonally downward and backward, the thread gripping section 45 was stationary at a position approximately corresponding to the lowest end of the segment 44.
revolves around the center of the segment 44 in a counterclockwise direction, rises slightly, and rotates in the same direction until it reaches a position where the clamping plates 46d and 47b face diagonally upward and backward, and pull the yarn end to a predetermined position. Wind it around the outer periphery of the presser member 48 by the length. Furthermore, at the same time, the threading member 34, which had been stationary at a predetermined position,
Move forward, and the thread hook 34b at the tip is attached to the front end plate 9.
It projects forward through the slit 9a and stops at a predetermined position above and in front of the thread support piece 67. During this time, both the knot forming mechanism 5 and the thread shifting mechanism 6 are in a stationary state.

In this state, after the tube needle 10 covering the needle 20 is pierced through the hang tag U and the object to be attached V, the second closing operation of the drive lever 11 is performed.

By this second closing operation, the needle 20
The threading member 34 performs a backward stroke and returns to its original position between the side plates 7a and 7b, but immediately after starting to return, the threading hook 34b of the threading member 34 is inserted into the needle hole 2 of the needle 20.
0a, hooks the thread T protruding horizontally from the needle hole 20a and the longitudinal crack 10a on the tip side, and then ascends once avoiding the thread support piece 67 to hold the thread T without receiving large frictional resistance. After being lifted and pulled back and passing over the thread support piece 67, it descends to the vicinity of the side of the needle 20, and at the same time as the needle 20 returns, the thread T is pulled back to a position slightly rearward from its original position.

In time with the return of the needle 20 to its original position, the thread gripping section 45 starts to revolve clockwise and rotate on its axis, as shown in FIG.
4 and reaches the position where it engages with the opening/closing cam 49, and the yarn end is pressed and held between the yarn end receiving plate 4a and the presser member 48, and then the knot is formed. The notches 46g, 47 of the clamping plates 46d, 46b, which are oriented upward, provide the thread T with the slack necessary for knot formation by the section 54.
j, 47k are aligned and opened by the opening/closing cam 49, and the thread at the position that will be the thread end during the next hanging tag attaching operation is inserted into the open notches 46g, 47j,
47k, and by rotating the opening/closing cam 49, the notches 46g, 47j, and 47k are closed to grasp the thread. At approximately the same time as such movement of the thread gripping section 45, the thread shifting plate 66 of the thread shifting section 63 rotates from the upright position to push down the thread that has been wrapped around the hang tag U and the object to be attached V.

The operation of these thread gripping parts 45 and the thread shifting plate 66
Almost simultaneously with the completion of the operation, the knot forming section 54 of the knot forming mechanism 5 operates, and both ends of the double thread T passed through the needle hole 20a and through the hang tag U and the object to be attached V are formed into a ring shape. They are tied together, and the ends are cut off by both beaks 56 and 57 to attach the hang tag U. During this knot forming operation, the thread hooking member 3
4 moves forward from the backward position and returns to the original position while giving the necessary slack to the thread. At the same time, the thread gripping part 45 returns to the original position while holding the thread end, and the next hanging tag attaching operation is carried out. Prepare for.

When targeting thin or soft objects,
Put your hand on the handle part 29b, turn the locking member 29, make the release recess 29b of the engagement rod 29a face the notch 10e, pull out the cylindrical needle 10, and lower it in the same manner as described above. Able to operate tag mounting machine and attach tags.

According to the above embodiment of the present invention, the threading member is
Since the knot forming section moves forward when performing the knot forming operation, the thread is given enough slack necessary for knot forming, which contributes to smooth and reliable knot forming.

(Effects of the Invention) The present invention is constructed as described above, and the cylindrical needle has a horizontal distal end side vertical crack facing the puncture needle hole, an upwardly facing base side vertical crack, and an upwardly facing vertical crack on the proximal end side that is inclined with respect to the axis. and an inclined crack that communicates the vertical crack with the vertical crack on the distal end side, and the longitudinal crack on the distal end side is continuous from the tip of the outer cylindrical needle to the position where the thread hooking member starts hooking the thread with the thread hook, and the inclined split is The thread should be formed with an inclination angle that smoothly guides the portion of the thread hooked by the thread hook of the thread hook of the thread hook and raised that comes into contact with the upper edge of the inclined crack into the proximal vertical crack. Accordingly, it is possible to reliably avoid increasing the frictional force that the thread receives from the cylindrical needle, and there is no need to cut out the edges of the crack, so that the strength of the cylindrical needle can be sufficiently maintained. In the invention described above, by attaching the cylindrical needle detachably with the engaging rod body, it is possible to easily adapt to the thickness, thinness, hardness and softness of the object to be attached. It has a notch formed by cutting out a portion that intersects with the locking member, and the engagement rod of the locking member is engaged with the notch of the cylindrical needle to lock the cylindrical needle in a predetermined position. By having a locking member that locks and a release recess that releases the locked state, the needle can be locked and released simply by rotating the locking member, and it can be used for both thick and thin objects. This has the effect of making it very easy to switch between the two.
