Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a price tag transport mechanism in a printing machine that prints one by one on a plurality of price tags held in a stacked manner.

Generally, the price tag transfer mechanism in this type of printing machine transports a plurality of price tags 51 stored in a stacked manner in a price tag box 50 to a feedout opening 50 of the price tag box 50 as shown in FIG.
The price tag 51 is pressed by the extrusion member 52 so as to be extruded from the outlet 50a, and the price tag 51 extruded from the outlet 50a is regulated by the regulating member 53 so that it is always one piece. The printed price tags 51 are engaged with a reciprocating feeding member 54 and transported one by one to a printing position 55.

However, according to this configuration, it can function normally when transferring an undeformed flat price tag 51, but for example, as shown in FIG. When printing is to be performed on a price tag 51, the sending member 54 does not engage with the edge of the price tag 51, so it cannot be transported.

Furthermore, if the price tag 51 is configured to be strongly pressed by the extrusion member 52 so that the feeding member 54 can engage with it to correct its curvature, the price tag 51 can be strongly held between the extrusion member 52 and the regulating member 53. However, the price tag 51 had the disadvantage that it was torn by the feeding member during transportation.

Among these deformations of price tags, the main reason for the deformation of price tags with hanging straps etc. It becomes thick and curved.

The present invention has been improved in view of the above-mentioned conventional drawbacks, and the object is to provide a price tag transfer mechanism in a printing press that has an extremely simple structure and is capable of transferring price tags no matter how deformed. .

The price tags 8 stacked and stored in the price tag box 9 are pressed from below by the pushing member 10 so as to be fed out from the feeding opening 9b.

That is, this extrusion member 10 is a substantially cylindrical member that passes through a sliding hole 9C formed below the price tag box 9 and is slidably supported by the base 4, and has a price tag attached to one end thereof. 8, and a coil spring 11 interposed elastically between it and the base 1 is in pressure contact with the other end.

Furthermore, a knob 10b is integrally provided on one side of the extrusion member 10, and this knob 10b projects outward from a long hole 12 formed in the base body 4.

Therefore, the pushing member 10 is urged upward by the coil spring 11 to push the price tag 8 out of the outlet 9b, and when the knob 10b is pressed down to compress the coil spring 11, the pushing member 10 The price tag 8 can be easily attached and detached because the price tag 8 also comes down.

Further, a guide member 13 is fixedly provided above the base body 4, and this guide member 13 slidably supports a sliding member 14 so as to guide it by two parallel rail portions 13a.

The sliding member 14 is connected to the cam wheel 3 via a transmission mechanism (not shown).
It is designed to reciprocate in the directions of arrows A and B in FIG. 1 in conjunction with the rotation of .

A mounting shaft 15 is vertically fixed to one side of the sliding member 14 with a screw.

Further, the mounting shaft 15 is provided with a substantially U-shaped frame 16 fixed with both side portions 16 a and 16 b.
Mounting shaft 1 between both sides 16a and 16b of this frame 16
5, there are three feeding members 18 each holding a spacer 17 between them.
One end of each is rotatably supported.

Each of these feeding members 18 has an abbreviated shape as clearly shown in FIG. The protrusion 18b is a stepped retaining portion 18 that engages with the price tag 8.
It has C.

Further, a pin 19 is fixed to pass through the intermediate portion of each sending member 18, so that each sending member 18 is in a state of being integrated with each other.

A hairspring 20 is wound around the outer periphery of each spacer 17, and one end of each hairspring 20 engages with the pin 19, and the other ends are connected to each other and engage with the frame 16.

Therefore, each sending member 18 includes the frame 16 and the spacer 17.
It is restricted from moving in the axial direction of the mounting shaft 15, and it reciprocates in the directions of arrows A and B together with the sliding member 14 while being biased counterclockwise in FIG. 1 by the mustache spring 20. .

Furthermore, an ink pad 22 is attached to an ink pad support member 21 that is fixed to the sliding member 14 by screws, and this ink pad 22 also moves back and forth along with the sliding member 14.

As shown in FIG. 2, a feeding member 18 is placed on the base body 4.
A plate-shaped regulating member 23 extending from below over the price tag box 9 to a part of the platen 5 is fixed with screws.

This regulating member 23 has three guide grooves 23a and 23b that penetrate in the vertical direction from the position where the feed member 18 is most retracted, that is, the position moved in the direction of arrow A in FIG. , 23C1, and the engaging portion 18C of each sending member 18 is connected to these guide grooves 23a, 23C1.
3 b , reciprocates through 23C.

Further, a regulating piece 23d is divided and formed by guide grooves 23a, 23b, and 23C.

The portions 23e and 23f located above the platen are thin, and there is a sufficient gap between the platen 5 and the outlet 9b of the price tag box 9 for one price tag 8 to pass through. .

Furthermore, in the portions of the regulating pieces 23d, 23e, and 23f that face the price tag box 9, the middle portions of the regulating pieces 23d, 23e, and 23f are
3 d , 23 e , 23 f curved surfaces 23 g , 23 h curved in the direction of reciprocating movement of the feeding member 18 so as to obtain the curved portions of the price tag 8 that are curved toward the sides 3 d , 23 e , 23 f .
, 23 i are formed.

Therefore, the pushing member 10 acts to push out a plurality of price tags 8 stacked and stored in the price tag box 9 from the feeding opening 9b. 23 e and 23 f, so that the feed member is always in contact with the feed member, regardless of whether it is a flat price tag 8 as shown in FIG. 3 or a curved price tag 8 as shown in FIG. 4. The 18 engaging portions 18a can engage only the highest price tag 8 and feed the price tags 8 onto the platen 5 one by one.

Furthermore, when attaching small price tags 8, in order to facilitate the transfer of the price tags 8, it is preferable to align each price tag 8 so as to touch the side wall of the price tag box 9 on the side wall of the platen 5. In this case, as shown in FIG. As shown, the edges of the price tag 8 that engage with the engaging portion 18a of the sending member 18 have curved surfaces 23g,
23h, 23i, so the engaging portion 18a
is also engaged with price tags 8 other than the highest price tag 8.

Therefore, two of the regulating pieces 23d, 23e, and 23f
Screw holes 23 are provided in each of the regulating pieces 23 e and 23 f.
j, 23k are formed, and these screw holes 23j, 23k are formed.
3 are provided with adjustment screws 24 and 25 that can move forward and backward from the curved surfaces 23h and 23i in the direction of the price tag box 9.

Therefore, as shown in FIG. 6, by making the tips of the adjustment screws 24 and 25 protrude by a predetermined length from the curved surfaces 23h and 23i, the engaging portion 18a of the feed member 18 is engaged only with the highest price tag 8. The position of the price tag 8 can be adjusted so as to

The reference number 26 is a pressing member that presses the price tag 8 to prevent it from falling off the price tag box 9 during printing.
27 is a counter that counts the number of printed price tags 8 in conjunction with the reciprocating movement of the print head 7. is a wire-like presser spring pressed onto the platen 5, and is adapted to temporarily hold down the price tag 8 that is sent onto the platen 5 and printed.

Next, the operation of the above configuration will be explained.

In FIG. 1, the print head 7 is in the raised position, the feeding member 18 is in the most retracted position, and the sliding member 14 first slides in the direction of arrow B in conjunction with the rotation of the cam wheel 3.

Along with this, the feeding member 18 and the ink pad 22 move forward, and as shown in FIG. 3, the engaging portion 18a of the feeding member 18 engages with the regulating piece 23d.

23 e and 23 f are in contact with the edge of the highest price tag 8.

Then, when the sliding member 14 further slides in the direction of arrow B, the ink pad 22 advances to below the print head 7.
Further, the feeding member 18 has one price tag 8 at each engaging portion 18C.
is sent to the printing position on the platen 5.

In this state, the price tag 8 on the platen 5 is pressed and held by the presser spring 28, and the print head 7 is lowered until its printing surface is pressed against the ink pad 22, and then returned to the upper position.

Next, the sliding member 14 slides in the direction of arrow A, and the feeding member 1
8 and ink pad 22 are returned to the most retracted position, and the print head 7 is lowered to print on the price tag on the platen 5 and then returned to the raised position.

This completes the transfer and printing of one price tag 8, but when the next price tag 8 is sent onto the platen 5 by the feeding member 18, the printed price tag 8 is pushed by the price tag 8 and pushed from above the platen 5. Fall.

By repeating the above operations, a plurality of price tags 8 are sequentially printed.

In addition, the middle part is the regulating piece 23 d , 23 e , 2
3. When the price tag 8 curved toward the f side is attached to the price tag box 9, the curved portion of the price tag 8 is connected to each curved surface 23 of the regulating pieces 23d, 23e, and 23f, as shown in FIG. g, 23h, and 23i, the engaging portion 18C of the sending member 18 reliably engages each price tag 8 and feeds the price tag 8 onto the platen 5.

On the other hand, when small price tags 8 are to be attached to the price tag box 9, the price tags 8 are aligned and attached so as to abut against the side wall of the price tag box 9 on the platen 5 side, as shown in FIG.

Then, tighten each adjustment screw 24.25 on the curved surfaces 23h, 23i.
If the engaging part 18C of the sending member 18 is adjusted so as to protrude more and engages only with the highest price tag 8, the retaining part 18 can be adjusted even if it is a flat price tag 8 or a deformed price tag 8. C
can be fed onto the platen 5 one by one.

In addition, in the above embodiment, in order to ensure that price tags 8 of any size are sent one by one, the regulation piece 23 is
Adjustment screws 24.25 are provided at e and 23f, respectively, and the position of the price tag 8 is adjusted using these adjustment screws 24.25.

However, the position of the price tag 8 may be adjusted as follows.

That is, as shown in FIG. 7, the regulating pieces 23'e, 23'
f, and on top there are protrusions 23'm and 23'n, respectively.
are integrally formed, and these protrusions 23'm, 23'n
A support shaft 29' extends therethrough and is rotatably provided.

Further, the support shaft 29' integrally has eccentric plates 30', 31' and a rotation knob 31', and the eccentric plate 30'
', are inserted into elongated through holes 23'p, 23'q formed in the regulating pieces 23'e, 23'f.

By rotating this rotary knob 32', the lower ends of the eccentric plates 30', 31' are adjusted to the respective curved surfaces 23'h, 2'.
The eccentric plates 30' and 31' act as members for adjusting the price tag 8 in the same way as the adjusting screws 24 and 25.

Note that the other configurations are the same as those of the above-described embodiments, so reference numbers indicating each part in the drawings will be appended with a dash (') and a description thereof will be omitted.

As described above, in the price tag transfer mechanism according to the present invention, since a curved surface is formed in the part of the regulating member that the price tag comes into contact with, the feeding member can reliably handle not only flat price tags but also deformed price tags. It is possible to transport one sheet at a time to the printing position.

Furthermore, since the adjustment member is configured to adjust the position of the price tags that engage with the feeding member, no matter what size of price tags are attached, the price tags will engage with the feeding member one by one. and can be transported to a printing position.
