Description

DETAILED DESCRIPTION OF THE INVENTION The present invention primarily relates to a labeler that thermally transfers drawing lines such as numbers, letters, and figures onto a label and affixes the thermally transferred label to an object.

Conventionally, this type of labeler peels off the label (109) temporarily attached to the release mount (110) at the tip of the release plate (106), as shown in FIG. is configured to be affixed to an object to be affixed (131).

However, in such conventional devices, since the thermal head (10) thermally prints lines of numbers, letters, figures, etc. on the label (10), the label (109)
) requires the use of a specially processed product such as a thermosensitive coloring type that develops color when heated, and has the disadvantage that it cannot be printed on labels made only of plain paper.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to perform thermal transfer onto a label made only of plain paper using a thermal head, etc., quietly and without vibration, and the printed label has good weather resistance. , it takes a relatively long time to print by thermal transfer, and even if the speed at which the label is peeled off and transported is different from the speed at which the object is conveyed by the conveyance means, the label can be correctly affixed to the affixing position of the object. The purpose of this product is to provide a heat-sensitive transfer printing labeler that can perform heat-sensitive transfer printing. This labeler consists of a thermal transfer device, a peeler that peels off the label, a label feed roller that feeds the label in an appropriate direction, and a take-up reel. The label is sent to the transfer position of the thermal transfer device through the rotation of the label feed roller,
The label is reversed at the tip of the peeler, the label is peeled off from the release paper, and the label is fed forward.The release paper from which the label has been removed is then conveyed while being held between a label feed roller and a roller, and then wound on a take-up reel. At the same time, the thermal transfer ribbon is conveyed opposite to the label that has reached the transfer position of the thermal transfer device, and is brought into contact with the label. The thermal transfer ribbon is brought into contact with the label, and only the portion of the thermal transfer ribbon to be printed is heated to heat and melt a portion of the thermal transfer ribbon and transfer it to the label.

Next, the operating status of this embodiment will be explained.

First, as shown in FIG. 1, the roll of the label continuous body (2) is attached to the winding reel (3), and the label continuous body (2) is transferred to the roller (40a) in the label issuing device (1).
), a roller (40b), a label detector (4) and a thermal transfer device (5) before reaching a peeler (6), and the release paper (10) is folded back at the tip of the peeler (6). ,
It is wound up by a take-up reel (8) via a roller (40c') and a label feed roller (7).

The label (9) in the label continuum (2) is detected by the label detector (4) by feeding the release paper (10) with the label feed roller (7), and then the label (9) is detected by the label detector (4). The part where characters, numbers, figures, etc. are thermally transferred is the thermal head (11) of the thermal transfer device (5).
It will be transported to the vicinity.

Then, the transferred label (9) is transferred to the thermal transfer ribbon (1) by the thermal transfer device (5).
2) and the thermal head (1) is placed in the area where the label (9) and the thermal transfer ribbon (12) come into contact.
The thermal head (11) is operated so that the head portion 1) comes into contact with the image, and the thermal transfer is performed by the thermal head (11).

In this case, the speed at which the label (9) is transported at the time of thermal transfer is such that the label (9) is thermally transferred by the thermal head (11).
The speed is slower than the speed at which 1) is transported.

The label (9) that has been transported at the above speed is removed by a peeler (
6), the label is peeled off from the release paper (lO) and fed out to the label transport speed adjusting device (16).

The fed-out label (9) is vacuum-suctioned by the suction conveyance belt (19) of the label conveyance speed adjusting device (16).

In the above vacuum suction, the suction device (22) is connected to the suction box (23).
), the shielding means (20), and the adsorption/feeding belt (19) to exhaust the air from the approximately airtight area formed by the suction opening (
This is done by creating a suction force in 19a).

The suction opening (19a) of this embodiment is a gap provided between a plurality of suction and feeding belts (19) as shown in FIG. 2(I), but the suction opening (19a) as shown in FIG. Adsorption feeding belt (19
) may be a suction hole (19b) provided in the hole (19b).

The label (9) attracted to the suction conveyance belt (19) is transferred together with the suction conveyance belt (19) because the drive roller (25) rotates the suction conveyance belt (19).

The speed at which the drive roller (25) transfers the suction conveyor (19) can be freely set by the rotation speed of the control motor (24) of the drive device (17).
Label (9) is attached to the object to be affixed (31) conveyed at 0).
The speed is set to be suitable for pasting the object (31), and a speed that is the same as or slightly slower than the speed at which the object to be pasted (31) is conveyed is suitable.

Thus, the label (9) is transported by the suction transport belt (19) in the direction of the driven roller (18) and is affixed to the transported object (31).

In addition, since the driven roller (I8) swings up and down with the driving roller (25) as a pivot point, the self-weight of the driven roller (18) can be applied to objects (31) of different heights and uneven surfaces. The label (9) can also be closely affixed to a shaped object (31).

Note that the conveying means (30) is provided with an encoder that generates a number of pulses corresponding to the distance that the conveying means (30) conveys the object (31), and the number of pulses generated by the encoder and the time between them are determined. Compare the amount with the elapsed time and compare it with the amount of time elapsed.
The control motor (24) of the drive device (17) determines the speed at which the label (30) is transporting the object (31) and transports the peeled label (9) at a speed that matches the determined speed.
may be controlled by the above determined speed, or the speed may be controlled by a speed regulator.

The present invention is not limited to the above, and for example, instead of the label transport speed adjusting device (16), as shown in FIGS. 3 and 4, a suction device (32) is used. After sucking the label (9) through the depressurized hole (19c), the air is pressurized with the air compressor (34) and the tube (3
3) blows out air to attach the label (9) to the object (31).
) may be used, and as shown in Figures 5 and 6, a pressure reducing device such as a vacuum pump (3) may be used.
After sucking the label (9) through the hole (19d) of the suction device (32), which has been depressurized in step 7), the actuator (35
) to move the label (9) downward with the piston (
36) may be used to apply pressure to the object (31);
The label (9) sucked through the hole (19e) of 2) may be attached to the object (31).

Since the present invention is configured as described above, the label includes:
Lines such as letters, numbers, and figures can be printed quietly and without vibration, and the printed area of the finished label is clear and does not smudge, has excellent weather resistance, and has a label transfer speed adjustment device. If used together, even if it takes a relatively long time to display letters, numbers, figures, etc. on the label by thermal transfer, etc., and the speed at which the label is transported is slow, the speed of the single speed means can be reduced to the normal speed. Convey the object to be affixed while maintaining the speed,
Labels can be affixed to objects under optimal conditions.
