Description

[Detailed description of the invention] The present invention is particularly concerned with a machine for punching out locking pieces for locking labels such as regular tags on fabrics, etc. In particular, a plurality of locking pieces are connected from a cartridge that is more closely connected than conventional ones. This invention relates to a locking piece punching machine suitable for punching out locking pieces.

2. Description of the Related Art A locking piece has conventionally been used to lock a label such as a regular tag to a product, particularly a fabric such as clothing.

1 and 2 are views showing a cartridge 5 in which 30 to 5 locking pieces are connected, and each locking piece is connected to the head 1.
, a filament portion 2, and a horizontal bar 3, which are arranged in a comb shape at regular intervals and connected by a connecting rod 4, forming an integral skin type.

FIG. 3 is a side view showing the structure of a conventional locking piece punching machine. To briefly explain the locking piece punching mechanism, the connection of the square locking piece cartridge 5 (head not shown) Stick 4 into groove 6
The cartridge 5 is loaded by inserting it in the direction of the arrow.

Next, by squeezing the grip lever 7, the piston pin 8 is pushed forward (to the left), the tip of the piston pin 8 pushes the end of the horizontal bar 3 of the locking piece, and the locking piece enters the needle tube 9. Pushed in.

At this time, the locking piece is moved to the connecting rod 4 by the action of the cutter 10.
The needle is cut off from the needle, and only one piece is pushed forward through the needle tube 9.

Further, when the grip lever 7 is squeezed in the negative direction, the auxiliary lever 11 that is linked to this tilts forward about the shaft 21, and the rod 1
Push the protrusion 13 provided on 2 forward.

The rod 12 is connected to the gear sending piece 16 by a cam (not shown), and when the rod 12 moves forward (leftward in FIG. 3), the gear sending piece 16 is lowered.

Then, the gear feed spring 14 attached to the gear feed piece 16 is released from the feed gear 15 with which it has been engaged so far and moves downward.

Next, when the grip lever 7 is loosened, the auxiliary lever 11 returns to the state shown in FIG. 3 due to the force of the spring 18.

At this time, the auxiliary lever 11 returns the piston pin 8 to its original position and simultaneously pushes the protrusion 17 of the rod 12 backward (to the right), and in conjunction with this, the gear sending piece 16 attempts to rise again. .

Then, the gear feed spring 14 engages with the lower tooth of the feed gear 15 that was previously engaged and pushes it up, causing the gear 15 to turn by one pitch.

When the feed gear 15 rotates, the cartridge 5 meshed with it is sent downward one frame, and the horizontal bar 3 of the next locking piece is sent out in front of the punching needle 8.

By repeating the above operations, the locking pieces are continuously driven out.

As can be understood from the above explanation, the locking piece cartridge 5
is sent out one frame at a time by the rotation of the feed gear 15 of the punching machine, so naturally each locking piece is attached at intervals (
P) in FIG. 1 was matched to the tooth pitch of the feed gear 15.

However, recently, cartridges have been improved, and cartridges have been manufactured in which the intervals P between the locking pieces are small and the locking pieces are closely arranged.

This is because the head 1 of the locking piece is likely to move if the distance between the locking pieces is large, and if a large number of cartridges are stacked and packaged, the head of the locking piece of one cartridge will move closer to the filament part of another cartridge. This is because they can get into the gaps between the two and become entangled, causing trouble in handling.

Therefore, by arranging the locking pieces closely and preferably shortening the filament portion, cartridges have been manufactured that eliminate entanglement between the locking pieces and improve manufacturing efficiency. .

However, if the pitch P of the cartridge changes, it goes without saying that the conventional punching machine cannot be used.

This is because when the pitch P of the cartridge changes, a gear with a pitch that matches this pitch is required, and furthermore, the vertical movement pitch of the gear sending piece that sends this gear, the reciprocating distance of the rod that operates this gear, etc. all change. In the end, the design of the punching machine itself had to be changed.

However, changing the model of the punching machine every time the pitch of the cartridge is changed is extremely inconvenient for the user, so we solved this inconvenience and somehow improved the pitch of the conventional punching machine. There was a strong demand for a way to load dense cartridges.

Therefore, the inventor of the present invention has repeatedly considered a locking piece punching machine that can continuously punch out locking pieces one by one by using a conventional wide pitch gear and loading a new narrow pitch cartridge. This led to the invention described above.

Hereinafter, the present invention will be specifically explained with reference to the drawings.

FIG. 4 is an enlarged view of the gear portion of the locking piece punching machine of the present invention.

The punching mechanism other than this part is omitted because it is the same as the conventional one shown in FIG.

In FIG. 4, the feed gear 15 has teeth 19 and teeth 20 with a low tooth height arranged alternately.

Then, the tooth pitch P of the gear 15 and the arrangement pitch P of the locking pieces
It is different from , and is approximately 4p = 3P.

As explained in FIG. 3, the state shown in FIG. 4 is that the gear feed spring 14 is now raised and the most unfired locking piece A1 (Ao
(has already been fired) is sent to the front of the piston pin 8.

At this time, if a conventional gear, that is, a gear with high tooth height, is used, the pitch P of the gear and the pitch P of the locking piece will be different, so the locking piece A1 will not mesh with the teeth of the gear and will not be fed smoothly. However, in the case of the present invention, since the teeth 20 with a low tooth height are arranged every other tooth, the locking piece A1 is placed on top of the low teeth 20 as shown in FIG. It is sent.

The stopping position of the locking piece A1 is fixed when the horizontal bar 3 of the locking piece (not shown in FIG. 4) hits a stopper (not shown) at the needle tube 9. Regarding sending the locking piece downward, it is possible to completely remove the teeth with low tooth height, but gear 1
As explained in FIG.
If all these low teeth are removed, when the gear feed spring 14 comes off the gear and goes down, the next tooth will be too far away and it will not be possible to catch it and push it up. be.

Therefore, as in the present invention, the height of the teeth can be made low so that the locking piece A1 can be placed thereon, and the gear sending spring 14 needs to be low enough to be locked.

By the way, the engagement portion between the gear 15 and the gear sending spring 14,
Not only is there some play in the engagement portion between the gear sending piece 16 equipped with the gear sending spring 4 and the rod 12, but also the cartridge 5 itself is made of Hewei resin and is flexible, so 3/4 Even when using a pitch cartridge 5, the horizontal bar 3 of the locking piece A1 at the leading end of the cartridge 5 is not connected to the needle tube 9.
When the gear 15 hits a stopper (not shown) located at , the gear 15 will no longer rotate.

Therefore, the horizontal bar 3 of the locking piece A1 at the most distal end of the cartridge 5 stops at the needle tube 9, and there is no problem in ejecting the locking piece A□ at the most distal end.

As mentioned above, in this invention, the tooth height of every other feed gear is lowered, and the tooth height of the lower gear is made low enough to engage with the gear feed spring. It becomes possible to eject not only cartridges with a pitch of P, but also cartridges with a pitch as close as 3/4 pitch.

Furthermore, since conventional molds can be used for everything other than the feed gear, manufacturing costs are also low.
