Description

[Detailed Description of the Invention] The present invention relates to a hand labeler with an improved label presser of a label tape mechanism.

Generally, as shown in FIG. 1, a hand labeler is equipped with a rotating drum 2 in a casing 3 with a large number of protrusions 1 protruding from its outer periphery. Label tape 4 is attached to the front edge of the label tape 4.
It is known that the material is peeled off from the surface and fed out under the compaction roller 6.

This type of hand labeler stamps the label a on the label tape 4 on the stamping stand 5, and prevents the label tape 4 from rising on the stamping stand 5 and peels off the label a accurately. In addition to the need for feeding, it is necessary to maintain the label tape 4 in a tensioned state before and after the stamp stand 5.

Conventionally, tape pressers 7 and 8 are provided above and below the rotating drum 2, and springs 9 and 10 are used to press the tape against the outer periphery of the rotating drum 2.

In such conventional hand labelers, multiple tape holders are installed in a narrow casing in a constantly energized state, so they have a large number of parts and require a lot of effort to install, resulting in high costs. Furthermore, during tape loading work, it is necessary to maintain the tape presser in the open state with one hand, or a special complicated mechanism is required to maintain the open state, which is uneconomical.

The present invention was devised to solve the above-mentioned drawbacks, and its gist is that it uses a rotating drum that sequentially attaches labels to the surface and transports the label tape passed over the stamping stand for each stamp. and a printing machine that reciprocates toward the stamping table, and an ink coating material support frame that protrudes between the stamping surface of the printing machine and the stamping table, and that extends toward the stamping table side of the printing machine. The ink applicator is provided with an ink applicator that swings in contact with the stamp surface during operation, and a spring that biases the ink applicator support frame in a direction in which the ink applicator is projected below the stamp surface. In a hand labeler in which a rotating drum is rotated in the label feeding direction, a sharp tape engaging protrusion is protruded from the outer periphery of the rotating drum, and a tape engaging protrusion is provided at the base of the tape engaging protrusion on the advancing direction side. The label tape is provided with a notch in which the label tape is engaged when the tape engaging protrusion is penetrated, and the label is pressed against the outer periphery of the rotating drum by the spring when the printing machine is retracted to the ink coating material support frame. The hand labeler is characterized by being equipped with a label holding piece for forcing the tape along the rotating drum.

Next, an example of the implementation of the present invention will be explained with reference to the drawings from FIG. 2 onwards.

In the figure, 10 is a casing.

A grip 11 is integrally provided on the rear end of the casing 10, and a grip lever 12 is provided below the grip 11 so as to be rotatable about a shaft 13 from within the casing 10.

A pair of rotating frames 14 are fixed to both sides of the grip lever 12 so as to be rotatable about a shaft 13, and a printing machine 15 is fixed downward between the tips of both rotating frames 14.

On the other hand, a stamp stand 16 is disposed inside the casing 10 at a position facing the printing machine 15, and the printing machine 15 is pressed against the surface of the stamp stand 16 by gripping the grip lever 12.

A tape feeding mechanism is provided on the rear side of the stamp stand 16.

This tape feeding mechanism consists of a rotating drum 17 that is rotated intermittently at a constant angle, ratchet teeth 18 formed on the end surface of the rotating drum 17, a ratchet pawl 19 that is pressed into contact with the ratchet teeth 18, and a ratchet pawl 19 that is fixed to the ratchet pawl 19. The grip lever 12 is connected to the sector gear 20 through a rack 21 that is meshed with the sector gear 20 and is fixed to the rotation frame 14 described above.
During the return operation, the rotating drum 17 is rotated by a certain angle.

In addition, tape engaging protrusions 22 are protruded at regular intervals on the outer circumferential surface of the rotating drum 17, and an annular groove 23 is formed on the outer circumferential surface.
The tip of a tape scraper 24 fixed to is inserted.

On the other hand, an ink application mechanism 25 is provided at an intermediate position between the printing machine 15 and the rotating drum 17.

The ink application mechanism 25 includes a roll-shaped ink application material 26 made of a sponge-like material impregnated with ink, and an ink application material support frame 27 that supports the ink application material 26. It is rotatably supported by a shaft 29 on a rising piece 28a of a frame 28 that supports the rotating drum 17.

Further, a spring engaging piece 30 is integrally molded at the center of the rear end of the support frame 27, and a spring 32 is tensioned between it and a spring engaging portion 31 provided on the frame 28, so that the tip of the support frame 27 is connected to the printing machine. Waist ink coating material 26 attached to the 15 side
is made to protrude below the print 15a.

Then, by lowering the printing machine 15, the printing 15a
contacts the ink coating material 26, and the ink coating material 25 is pushed by the printing machine 15 and rotated rearward.

Further, a label presser piece 33 is integrally molded at the rear end of the support frame 27.

The label presser piece 33 has its tip side folded back into an arc shape, and its back surface is brought into contact with the outer periphery of the front surface of the rotating drum 17 when the printing machine 15 is in the raised state.

In the figure, 34 is a grip lever return spring, 35 is a tape holder, 36 is a pressure roller for label pasting, 3
7 is a stopper for preventing the rotating drum from reversing, and 38 is a tape guide.

In addition, as shown in FIG. 3, the protrusion 22 on the outer periphery of the rotating drum 17 has a notch 22a formed at its base on the traveling direction side, and by engaging the label tape A with the notch 22a, it is prevented from lifting off from the rotating drum. I'm trying to make it happen.

The hand labeler configured in this manner stores the label tape A pulled out from the tape holder 35 between the rotating drum 17 and the label holding piece 33, under the tape guide 38, and on the stamping stand 16.
, and then folded back at the lower rear at the leading edge of the stamping base 16 so that the leading end is aligned with the lower rear of the rotary drum 17 .

In this state, by gripping the grip lever 12, a stamp is stamped on the label a on the stamp stand 16, and by releasing the grip lever 12, the rotary drum 17 is rotated during its return operation, and the front edge of the stamp stand 16 stamps the label a. A is peeled off and fed out under the rolling pressure roller 36, and the label tape A after peeling is
is separated from the rotating drum 17 at the tape scraper 24 position and sent out backward.

During this operation, the printer 15 is lowered by gripping the lever 12 and the ink coating material 26 is pushed down, thereby rotating the support frame 27 and moving the label presser piece 33 away from the rotating drum 17. Ru.

After the printing machine 15 completes stamping, when the printing machine 15 moves to a rising operation, the rotary drum 17 is rotated in conjunction with this.

At this time, the label presser piece 33 is separated from the rotating drum 17, but the tape engaging protrusion 22 on the outer circumferential surface penetrates the label tape A and engages with the notch 22a at its base.
The label tape A is operated with the label tape A engaged with the outer periphery of the rotating drum 17, and the label tape A is fed.

While the rotary drum 17 is being rotated in this way, the printing machine 1
5 is lifted, the ink coating material 26 is moved upward by the tension of the spring 32 as the stamp surface rises, and at the same time, the label presser piece 33 is rotated toward the outer periphery of the rotating drum 17, and the printing machine 15 is lifted. The label tape A is pressed against the outer periphery of the rotating drum 17 at the position in front of the other end, and the label tape A is pressed against the outer periphery of the rotating drum 17 and engaged with the protrusion 22 .

The hand labeler of the present invention is constructed as described above, and has a sharp tape engaging protrusion protruding from the outer periphery of the rotating drum, and the tape engaging protrusion penetrates the base portion of the tape engaging protrusion in the traveling direction. An ink application material that is provided with a notch with which a label tape is engaged, so that the label tape can be fed even when the label presser piece is not pressed against the rotating drum, and that is operated together with a printing machine. A label holding piece is provided on the support frame, and when the printing machine retreats, this label holding piece is pressed against the outer periphery of the rotating drum by a spring, forcing the label tape to follow the rotating drum and engaging the label engaging protrusion. By doing so, the label tape can be accurately aligned along the rotating drum when the rotating drum operates, that is, when transporting the label tape, as in the past, and the label tape presser can be moved independently as in the past. Compared to separate parts, the structure is significantly simplified, the device itself is simple, the number of parts is small, the manufacturing and assembly process is significantly simplified, and it can be provided at a low price.
