Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically attaches a label strip peeled off from a tape strip of a label continuum composed of label strips temporarily attached to a tape strip and fed out to an article. The present invention relates to an apparatus for controlling the position of the leading end of a label piece fed out in a label sticking machine capable of sticking a label.

[0002]

2. Description of the Related Art Conventionally, in this type of automatic label sticking machine, the peeled label piece is stuck to an article transferred by a transfer means such as a conveyor by the reversal and pulling action of a tape-shaped mount. There are various kinds of label pieces to be put on, and their lengths (label pitches) are different. Thus, the standby position of the feeding label of the next stage is displaced depending on the size of the label pitch. If the label sticking operation is continued in such a displaced state (the leading end of the label piece in the next stage is not uniform), not only the position of sticking the label on the article becomes uneven, but also the sticking of the label becomes incomplete.

[0003]

As a countermeasure against this, when sticking label pieces having different label pitches, manual adjustment is performed by moving the set position of the sensor to align the leading end of the feeding label of the next stage with the leading end of the peeling member. Need.

Thus, according to the present invention, even if the label pieces having different label pitches are different from each other, the tip of the feeding label piece in the next stage can be automatically aligned with the tip of the peeling member without performing the manual adjustment. An object of the present invention is to provide a possible label feeding control device.

[0005]

In order to achieve the above-mentioned object, the label feeding control apparatus of the present invention sets a transmission type sensor S near the tip of the label passage of the peeling member 10 provided in the main body 5. When this sensor detects the advancing front end 4 of the feeding label piece 3 of the next stage, this detection signal is output to the control unit 13, and this output is transmitted to the motor M, and the tape-shaped backing sheet 2 after the label is peeled off. Is pulled by the pulling action of the pulling means (pulling roller 15, pressing roller 16) to advance the label piece 3 by the set transfer distance L, and the forward end 4 of the label piece 3 is aligned with the leading end 11 of the peeling member 10 and stopped. The control unit 13 provided with such a timer circuit is configured to control the transfer of the transfer distance L set for the label piece 3 in the next stage.

[0006]

In FIG. 1, the roll-shaped label continuous body 30 becomes the label continuous body 1 and passes through a plurality of guide rollers 8, 8 and 9 and then the tape-shaped backing sheet 2 is reversed at the tip 11 of the peeling member 10. At least, the tape-shaped mount 2 is pulled by the pulling means of the pulling roller 15 and the pressure bonding roller 16.
The label piece 3 that is temporarily attached to is peeled off. Figure 2 here
As shown in detail in (a), the transferred label continuum 1
Is detected by the transmissive sensor S. That is, since the sensor is a transmissive sensor, the portion of the tape mount 2 (the gap G between the label pieces 3 and 3) or the portion of the label piece 3 temporarily attached to the tape mount 2 (both members). ) Is detected by the potential difference.

Thus, when the sensor S detects the leading end 4 of the feeding label piece 3 in the next stage (corresponding to both parts of the tape-shaped backing sheet 2 and the label piece 3), this detection signal is output to the control section 13, The motor M is passed through a timer circuit that sets a predetermined t seconds.
To transmit and rotate. This rotation is transmitted to the pulling roller 15 via the timing belt 14 to transfer the tape-shaped mount 2 for t seconds.

Next, the label continuum 1 on the peeling member 10
Moves forward a specified transfer distance L, and as shown in FIG. 2B, the leading end 4 of the feeding label piece 3 in the next stage stops at a position matching the leading end 11 of the peeling member 10. Therefore, since the tip 4 of the feeding label piece 3 of the next stage always stands by in such a state as to coincide with the tip 11 of the peeling member 10, the label piece 3
Is accurately and stably attached to a prescribed position of the article 40 conveyed by the conveyor 50.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A label feeding control device of the present invention will be described with reference to the accompanying drawings. In the overall side view of FIG. 1, a label continuous body 3 in a roll shape is provided above the frame 6 of the main body 5.
A supply unit 7 of 0 is provided, and a label peeling member 10 is arranged below the supply unit 7. A transmissive sensor S is set on the peeling member 10 so as to face the label passage. Specifically, as shown in FIG. 2A, the light emitting element S ₁ embedded in the peeling member 10 and the label sensor are installed above the label passage. consists Jukoko S ₂ Metropolitan was, the light emitting member S ₁ is wired into the control unit 13. A timer circuit is additionally provided in the control unit 13 and is connected to the motor M so that the motor M can be operated for a certain time (second) regardless of the label pitch. In this embodiment, the motor M is explained as time setting, but the present invention is not limited to this. That is, a stepping motor may be adopted to regulate the feed angle and feed amount of the motor.

Next, on the one hand, the rotation of the motor M is transmitted to the pulling roller 15 for pulling the tape-shaped mount 2 after the label is peeled off with the timing belt 14 and the winding part 18 for winding the tape-shaped mount 2 on the other side. It is transmitted to the (winding roller member) via the round belt 19. Next, FIG. 1 showing the entire front surface, and FIG. 2 showing the detection state of the label piece.
The operation of the present apparatus will be described with reference to FIGS. 4A and 4B showing (a) and (b) and its operating state as a flowchart. First, as shown in FIG. 1, the label continuum 1 is set in the main body 5 of the label sticking machine. This set means that the tape-shaped mount 2 from which a predetermined number of label pieces 3 have been peeled off from the tape-shaped mount 2 is reversed at the tip 11 of the peeling member 10 via a plurality of guide rollers 8, 8, 9. , Towing roller 1
5 and the pressure roller 16 are sandwiched between the ends of the winding unit 18
At the winding state.

Thus, after this label setting is completed, the power source is turned on, and after the interval of 3 seconds, the feed of the label continuum 1 is completed, the motor M is rotated. The rotation of the motor M causes the pulling roller 15 to rotate, pulls the tape-shaped mount 2, and the winding unit 18 also rotates to wind up the tape-shaped mount 2 to reach the state of FIG. 2A. That is, the transmissive sensor S is the next label piece 3
Is the detection state. Specifically, the transmissive sensor S has a voltage of 0.5 V when only the tape-shaped mount 2 (the gap G between the label pieces 3 and 3) is used, but when the tip 4 of the label piece 3 is detected, the voltage is changed to 2 V. .

Thus, when this potential difference is output to the control unit 13, a signal is sent to the timer circuit set for t seconds to rotate the motor M. This rotation of the motor is transmitted to the pulling roller 15 via the timing belt 14 to transfer the tape-shaped mount 2 for t seconds. The transfer of the tape-shaped mount 2 for t seconds is the specified transfer distance L (12 m / m). As shown in FIG. 2B, the state after the movement of the label piece 3 at the next stage is the position where the label piece 3 reaches this position at the position where the forward end 4 of the label piece 3 matches the tip 11 of the peeling member 10. , The motor M stops. Therefore, the pulling roller 15 is stopped, so that the label piece 3 is stopped. In this state, the completion signal is output and the completion is stopped.

Next, the article detection sensor S set on the conveyor frame 51 facing the article transfer path of the conveyor 50.
When A (see FIG. 3) detects the arrival of the article 40, it outputs this detection signal to the control unit 13. Then again the motor M
Rotates for the label pitch t ′ seconds, the expected label piece is fed out, and the label pressing roller 20 attaches the label to the article.

In this way, the cycle of stopping the label at the specified transfer distance L, feeding the label, and sticking the label is repeated. Note that, in FIG. 4, a completion signal is output if "NO in operation at feed", but YES means that the label is manually attached, and in this case, key operation is required.

[0015]

As described above, according to the present invention, the tape-shaped mount 2 on which the label piece 3 is temporarily attached is turned over by the peeling member 10 provided on the main body 5 of the label sticking machine to move the label piece 3 onto the tape-shaped mount 2. In a label feeding control device in a label sticking machine that peels off more and labels the article 40, a transmissive sensor S is set in the vicinity of the tip 11 of the label passage of the peeling member 10, and the sensor S of the feeding label piece 3 is set. When the leading edge of the movement is detected, this detection signal is output to the control unit 13, and this output is transmitted to the motor M to move the label piece 3 forward by the set transfer distance L by the pulling action of the tape-shaped backing sheet 2, and the progress thereof. Since the tip 4 is configured to be controlled by the control unit 13 provided with a timer circuit set so as to stop when the tip 4 coincides with the tip of the peeling member 10, the labels of label pieces having different label pitches are different. The tip of the next stage of the feeding label can be matched to the tip of the peeling member at the time of feeding. Therefore, it is not necessary to move the setting position of the sensor each time the label pitch is different as in the conventional case, and the delivery label has an advantage that it can be reliably attached to a desired position of the article.
