Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Technical Field] The present invention relates to an automatic price tag device for attaching price tags, etc. to cloth products.

[Prior art]

Conventionally, when performing such work, as shown in Fig. 1, a price tag 2 is applied to a cloth 1, and a price tag attaching machine 3
After passing the needle 4 through the hole 2a of the price tag and the cloth 1, the trigger 5 was pulled and the binding piece 6a was driven in. As is well known, the attaching machine 3 is pistol-shaped, and a bundle of binding pieces 6 is mounted in a vertical groove at the tip, and when the trigger 5 is pulled, the binding pieces are ejected one by one along the groove in the needle 4 (see Fig. 3). It has a structure that Therefore, cloth 1 and price tag 2 are
As shown in the figure, they are connected by a binding piece 6a. Although the development of this price tag attaching machine greatly improved the troublesomeness of attaching price tags using thread binding, it was still difficult to hold the cloth in the left hand and apply the price tags one by one to the designated positions with the right hand, holding both in the left hand. After transferring the labels, the attachment machine had to be held in the right hand again, and it was impossible to attach the price tags continuously while holding the attachment machine in one hand.

On the other hand, there are known automatic price tag attaching machines that do not require manual handling of price tags; The drawback was that it was not possible to send out just the price tag after removing the price tag. In other words, since the lever and the price tag feeding means are mechanically interlocked, when the lever is pulled, the binding pieces are ejected together with the price tag, so the binding pieces are wasted.

[Purpose of the invention]

Therefore, the present invention aims to eliminate such conventional drawbacks.

[Structure of the invention]

The present invention that achieves this object includes: a box for storing a price tag; a slider for feeding the price tag from the box to a predetermined exit; a driving member serving as a driving source;
It is comprised of a drive transmission member that transmits the driving force of the drive member to the slider, and a clutch member that performs drive switching. The drive transmission member includes a cam that is applied with a rotational force by the drive member and rotates when disengaged from the stopper, and the slider is slid in the price tag sending direction by the rotation of the cam. It consists of a link rod. Further, the clutch member includes a rod that is rotatably attached to the front surface of the box and that interlocks with a flapper, a stopper that engages with the cam, and a stopper that rotates in synchronization with the rotation of the flapper. It consists of a latch lever that releases the engagement of the stopper.

In the present invention, a mainspring is used as the drive source of the feeding device, and a gear, a cam, and a link are combined as the drive transmission member. In addition, each part of the device is equipped with a simple adjustment mechanism so that it can be adapted to various thicknesses, lengths, and hole positions of price tags.

〔Example〕

Embodiments of the price tag feeding device of the present invention having these features will be described in detail below with reference to the accompanying drawings. FIG. 3 is a perspective view showing the price tag feeding device of the present invention integrated into the price tag attaching machine 3. This device has a box 7 for storing the price tag 2.
, a slider 8 that feeds the price tag from the box 7 to a predetermined exit, a drive member 9 that serves as a drive source, a drive transmission member 10 (see FIG. 7) that transmits this drive force to the slider 8, and a clutch that switches the drive. It is composed of a member 11 (see FIG. 7). Note that 3a extending to the lower end of the attachment device 3 is a cap that can be covered by the needle 4.

As you can see from Figure 4, Box 7 has a price tag 2 inside.
are stored in an overlapping manner, and are maintained in a press-contact state by the presser plate 12. Two core rods 13, 13 are fixed to the presser plate 12 and pass through the bottom surface 7a of the box 7, and a spring 1 is installed between the presser plate 12 of each core rod 13, 13 and the inner surface of the box bottom surface 7a.
4 and 14 are wrapped around each other, and this applies the required pressing force to the holding plate 12. Further, an angled guide 15 is fixed to the inner surface of the box in order to prevent the holding plate 12 from wobbling in the lateral direction when it moves. Therefore, the notch 12a formed at the end of the presser plate 12 lightly touches the guide 15, so that the presser plate 12
can be moved vertically without blurring. A slider 8 is attached to the top surface of the box, which is connected to a link rod of a drive transmission member 10 as will be described later, and slides along the top surface of the box. Further, the slider 8 is integrally provided with a pusher piece 16, and the pusher piece 1
6 is a curved portion 16a and a stepped portion 16 as shown in FIG.
b, and is fixed to the slider 8 via a shaft 17 with a nut 18. The curved portion 16a is partially buried in the guide 15, and the remaining portion is in contact with the price tag 2. Further, the end of the price tag 2 is engaged with the stepped portion 16a of the push piece 16, so that when the push piece 16 moves to the left together with the slider 8, only one price tag 2 is sent out from the box 7. For this reason, the height of the stepped portion 16b must be dimensioned to be somewhat lower than the thickness of the price tag 2. Incidentally, in this embodiment, the thickness of the price tag 2 is 0.45 mm, and the stepped portion 16
The height of b is 0.3 mm. When using price tags of different lengths, loosening the nut 18 of the pusher piece 16 allows the pusher piece 16 to be moved along the elongated hole 8a of the slider 8 (see also FIG. 3). price tag 2
In order to make the irregularities even more perfect, the guide 15 may be brought into contact with the end face of the price tag 2.

An opening 19 is provided in the upper left part of the box 7, and only one price tag 2 is ejected from this opening 19 by movement of the slider 8. The gap between the openings 19 can be adjusted using an adjusting plate 20 provided near the openings 19. The adjusting plate 20 has a longitudinally extending elongated hole 21 and is attached to the side surface of the box by a screw 22, so that by loosening the screw 22, the adjusting plate 20 can be moved up and down.
A flapper 24 is pivotally attached to the upper surface of the box via a hinge 23, and a pin 25 is in contact with the upper surface of the flapper 24. As can be seen from FIG. 3, the flapper 24 has a notch at the center of its tip, where the hole 2a of the price tag 2 sent out is located, and the needle 4 of the attaching machine 3 passes through the flapper 24. The pin 25 is connected to the clutch member 11 as will be described later and is movable a predetermined distance in the longitudinal direction, so that the flapper 2
4 is the hinge 23 by the angle regulated by this pin 25.
It can be rotated using the fulcrum as a fulcrum. Box 7
A hinge 26 is provided at the upper right end of the box 7 so that the top surface of the box 7 can be opened together with the slider 8, flapper 24 and adjustment plate 20 as shown in phantom lines in FIG. can be placed in box 7 from above. Note that when opening the box 7, the pin 25 that gets in the way is removed, or the pin 25 is installed in advance so that it can be rotated through 90 degrees. In the case of a type in which the top surface of the box is opened, the guide 15 is attached to the bottom surface 7a or side surface of the box. In addition to this, the price tag 2 may be inserted on the top surface or the end surface in FIG. 3.

As can be seen from FIG. 6, the drive member 9 uses a mainspring in this embodiment. Various sources including a motor are conceivable as the driving source for the feeding device, but a mainspring is most desirable in terms of its weight and required rotational torque. One end of the drive member 9 is wound around the shaft 27, and the other end engages with a notch 28a formed in the side surface of the cover 28. The upper end of the shaft 27 has a square cross section and projects upward through the cover 28, and by rotating the shaft 27 with a box handle 29, the mainspring can be wound. The driving force from the mainspring is transmitted to the slider 8 via the drive transmission member 10. The drive transmission member 10 of this embodiment is composed of a gear 30, a pinion 31, a camshaft 32, a cam 33, a roller 34 (FIG. 7), and a link rod 35 (FIG. 7). , are housed within the support plate 36 and the substrate 37. The gear 30 is fitted below and coaxially with the drive member 9, and a pinion 31 on the camshaft 32 meshes with the gear 30. The cam shaft 32 is pivotally supported between the cover 28 and the support plate 36, and a cam 33 is fitted to the lower end of the shaft.
As can be seen from FIG. 7, the cam 33 has the shape of two blades, and each blade has a flag 33a on the lower surface of its tip.
and 33b are provided (FIG. 6). Therefore, the cam 33 is constantly applied with a force to rotate counterclockwise in FIG. 7 by the driving member 9;
Since the flag 33a is engaged with the stopper 38, it is stopped at this position. FIG. 7 is a plan view of the drive transmission member 10, in which the box 7, gear 30, pinion 31, camshaft 32, cam 33, and roller 34 are shown in imaginary lines. cam 3
A roller 34 is in contact with the box 3, and the roller 34 is installed in the box 7, as can be seen from FIG. Further, a substantially U-shaped support frame 39 is fixed to the bottom surface of the box 7, and both sides of the support frame 39 are connected to the base plate 37.
The box 7 can be slid back and forth along a guide 40 formed in the box 7. The right end of the supporting frame 39 projects inward, and an L-shaped link rod 35 is pivotally attached to this portion via a pin 41. An elongated hole 35a is formed at one end of the link rod 35 and supported by a pin 42 on the base plate 37, and the other end is pivotally connected to the slider 8. Therefore cam 3
3 rotates 180 degrees counterclockwise, the roller 34
The box 7 is pushed upward as seen in FIG. 7, and the link rod 35 pivoted to the support frame 39 pivots clockwise about the pin 42, causing the slider 8 to move to the left. The pushed up box 7 is pulled back to its original position by the action of the spring 43. The spring 43 connects the tip of the supporting frame 39 and the base plate 3.
It is installed between 7. The detailed operating conditions thereof will be described later in FIG. 8 together with the operation of the clutch member 11.

As mentioned above, since the rotation of the cam 33 is restrained by the stopper 38, the clutch member 11 is provided to operate the cam 33. The clutch member 11 has a stopper 38 that stops the cam 33.
, a latch lever 44 that releases the stopper 38, and a rod 4 that operates the latch lever 44.
It consists of 5. The right end of the stopper 38 is pivotally connected to a pin 46 on the board 37, the left end abuts a pin 47 on the board 37, and the lower surface of the stopper 38 is biased clockwise by a spring 48. Also the 6th
As can be seen from the figure, the stopper 38 is formed with a stepped portion 38a, which is attached to the flag 33a of the cam 33.
(or 33b) is engaged, the cam 33
operation is stopped. To release the cam restraint of the stopper 38, the stopper 38 may be slightly turned counterclockwise to release the engagement between the flag 33a and the stepped portion 38a. The latch lever 44 does this, and the center part of the latch lever 44 is connected to the board 3.
7, and a roller 44 at one end.
a is provided and contacts the stopper 38, and the other end is hook-shaped and is locked to a pin 49 on the board 37. The rod 45 is attached to the left side of the board 37 so as to be slidable in the vertical direction, and the lower end is attached to the spring 5.
It is pulled downward by 0. A long hole 45a is formed in the rod 45 in the longitudinal direction, and the substrate 3
Up and down movement can be performed along pins (not shown) on 7. The upper end of the rod 45 is the flapper 24
As the flapper 24 rotates, the pin 25 and the rod 4
5 is pushed up, and then the flag 51 provided on the rod 45 pulls the hook of the latch lever 44, causing the roller 44a to rotate the stopper 38 counterclockwise and remove this stepped portion 38a from the flag 33a of the cam 33. . Since the spring 48 is constantly acting on the stopper 38, the release operation of the stopper 38 by the latch lever 44 is instantaneous.
Therefore, when the cam 33 rotates 180 degrees, the flag 33b on the opposite side is moved again to the step 38a of the stopper 38.
engage with.

As can be seen from FIG. 3, a lever 52 is provided near the opening 19 of the box 7, the center of which is pivoted to the side surface of the board 37, and when the lever 52 is pressed down, the other end The flapper 24 is pushed up. The lever 52 is used when first pulling out the price tag 2 in the box 7, but it can also be used in the unlikely event that the price tag feeding operation of the slider 8 does not work properly due to the flapper 24. Furthermore, as can be seen from FIG. 6, the price tag attaching machine 3 is attached to the left side of the board 37 via a screw 53, so that by loosening this, not only can the attaching machine 3 be removed, but also the attaching machine 3 can be rotated. needle 4
The vertical position of can be aligned with the hole 2a of the price tag.

Next, the manner of use of the apparatus of the present invention and the order of operation of each part will be explained with reference to FIGS. 3 and 8. First, a predetermined bundle of price tags 2 is stored in the box 7, and the push piece 16 of the slider 8 is adjusted according to the length of the price tags 2. Next, the gap between the box openings 19 is adjusted using the adjusting plate 20 of the box openings 19. The mainspring of the driving member 9 is wound in advance by the handle 29. Then, when the lever 52 is pushed down, the price tag 2 becomes 1.
(This operation is exactly the same as that by the flapper 24 described below), but the hole 2a of the price tag 2 and the attaching machine 3
If the needles 4 do not match, adjust the position of the needles 4 using the screw 53 described in FIG. After adjusting each part, insert the needle 4 into the specified cloth item and pull the trigger 5.
If the needle 4 is removed after pulling , the price tag 2 is attached to the cloth 1 in exactly the same way as shown in FIG. The feeding device of the invention operates when the needle 4 is withdrawn. That is, in the state shown in FIG. 2, half of the price tag 2 still remains in the box 7, and when the cloth 1 is pulled, the attached price tag 2 is pulled out together with the flap 24 that was in contact with the price tag 2. It will be pulled toward you (downward in Figure 8). Therefore, the feeding device operates as the flapper 24 rotates, and the interlocking relationship of each part will be explained below with reference to FIG. This figure is similar to FIG. 7, but is shown in a simplified manner for ease of understanding.

First, when the flapper 24 turns upward, the pin 25 in contact with it also moves upward together with the rod 45. At this time, the flag 51 at the lower end of the rod causes the latch lever 44 to pivot clockwise, so that the stopper 38 moves downward and releases the blocking action of the cam 33. Since the cam 33 is constantly applied with a counterclockwise rotational force by the drive member 9, it rotates in this direction when the stopper 38 is released. As the cam 33 rotates, the roller 34 and the box 7 move upward against the spring 43 and are pushed up to the position indicated by the imaginary line. At this time, L-shaped link rod 3
Since one end of 5 is pivotally connected to the pin 42 through the elongated hole 35a, it can be rotated by θ using this as a fulcrum.
The slider 8 (more precisely, the push piece 16) connected to the other end of the link rod 35 pushes out the price tag 2 by a predetermined distance as shown by the imaginary line. When the cam 33 passes the imaginary line position, the roller 34' comes off the cam surface, and the box 7, link rod 35 and slider 8 are pulled by the spring 43 and return to their original positions. Since the stopper 38 immediately returns to its original position simply by momentarily releasing its blocking action using the latch lever 44, the cam 33 that has rotated 180 degrees is stopped by the stopper 38 in the same way as at the beginning. price tag 2
The needle returns downward together with the box 7 while protruding from the opening 19 of the box, so that the hole 2a of the price tag fits into the needle 4 and the condition shown in FIG. 3 is again achieved.

〔Effect of the invention〕

As described above, according to the present invention, when the flapper is pivoted forward, the force is transmitted from the pin to the rod to the latch lever to the stopper, and the engagement between the stopper and the cam is temporarily removed by the cam. As the box moves forward, the link rod rotates and the slider pushes out the price tag from the opening on the side of the box.

Therefore, according to the present invention, only price tags can be sent out without pulling the trigger of the price tag attaching machine, and there is no need to waste binding pieces.
