Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an automatic label sticking device for sticking a label onto an article conveyed by a conveyor or the like.

(Prior Art) Conventionally, as a technique of this kind, the applicant's prior application, Jitsukai Sho 63-
No. 64613 (Japanese Utility Model Publication No. 4-7055) can be mentioned. With reference to the publication, a stepping roller that moves up and down is arranged between the printer and the label peeling section to stock the surplus of the printed label group.

(Problems to be solved by the invention) In the present invention, although the label issuing speed in the printer and the label attaching speed to the article conveyed by the conveyor are different from each other, the stock amount is constant, It is an object of the present invention to provide an automatic label sticking device capable of surely sticking each label.

Generally, the label issuing speed in the printer is slower than the label attaching speed to the conveyed article. In other words, it is possible to automatically apply a label to a printer that is slow to issue a label, which can be continuously applied to an article that is conveyed by a certain amount but continuously without stopping the conveyor. Is the subject of.

Specifically, since the above-mentioned publicly known document which is similar to this problem is configured to stock the printed label continuous body by the vertical movement of the step roller, this setting direction is limited to the vertical movement direction. Therefore, the present invention provides an automatic label sticking device that can be applied in any setting direction.

(Means for Solving the Problems) In the present invention, the printed label 9 fed between the printer 1 and the label sticking roller 19 is attached to the tape-like mount 8 to the label continuum 7 and the fulcrum 12 to the fulcrum 12. 180 ° as the center
Suspended and displaced on a stock member 10 of a label consisting of two actuating rollers 14 and 15 which are relatively oscillated in a positional relationship with each other. The configuration is such that the continuum 7 is stocked.

Further, the stock member 10 is provided with a printed label continuum 7
In order to stock the label continuous body 7, a spring 17 that elastically biases the label continuous body 7 in the direction in which the transfer path length of the label continuous body 7 is extended (label feeding direction) is provided. A detector 16a, such as a limit switch, which detects the displacement of the transfer path length from the maximum expanded state to the contracted direction and outputs a label issuance control signal to the printer 1 is provided.

(Operation) The maximum amount of the label stock issued to the stock member 10 is detected by outputting a signal from the detector 16a to the printer 1 when the tip of the detector 16a comes into contact with the operating roller 14, and the label is printed. Issuance is suspended (see Figure 2).

Next, when the stock amount of this issued label reaches the specified amount,
This signal is transmitted to the movable conveyor 20, and the conveyor 20
When the sensor 3 detects the article 22 mounted on the label 22, the pulling roller 5 is rotated, and the pulling action of the tape-shaped mount 8 pulled by the pulling roller gradually peels the label 9 at the peeling portion 18. .

Thus, the label stock member 10 is successively swung so as to be displaced from the state shown in FIG. 2 to the state shown in FIG. That is, the stock member 10 including the stay 11, which is a support member on which the pair of actuating rollers 14 and 15 suspending the printed label continuum 7 is mounted, is pulled by the tension force of the tension spring 17 which is the urging member of FIG. The tape-shaped mount 8 is pulled by the rotation of the pulling roller 5 from the stock state of the excess label that is inclined in the label feeding direction, and the peeling portion 18 thereof is provided.
Then, the label 9 is peeled off and fed to the bottom surface of the sticking roller 19.

When a label is attached to the article 22, a part of the suspended label continuum 7 is unwound, so that the stock member 10 rotates counterclockwise about the fulcrum 12 against the tension spring 17. When the length of the transfer path of the label continuum 7 is minimized, that is, when the label stock is swept out, as shown in FIG.
14, 15 are almost displaced to the upright position, and the detector detects this displacement (when the tip of the detector 16a separates from the working roller 14)
Then, this signal is transmitted to the printer 1 for label issuance, and label issuance in the next stage is started.

Next, as the label is issued in the next stage, the stock member 10 is sequentially rotated clockwise by the tensioning action of the tension spring 17 to return to the stock state of the label of FIG. 1 as shown in FIG. Incidentally, it takes some time for the label stock to be completely restored, and at this time, the label sticking to the article 22 is temporarily stopped. Therefore, this device can continuously apply a certain amount of the issued label to the article.

As described above, the stock member 10 including the pair of actuating rollers 14 and 15 swings like a seesaw after the label is issued or the label is attached.

(Embodiment) The first embodiment shown as an embodiment of the automatic label sticking apparatus of the present invention.
Description will be made with reference to the overall schematic view of the drawing.

The printer 1 for issuing the label is supported by the frame 2,
A conveyor 20 suspended between a pair of rotating wheels 21, 21 is arranged below the frame 2. The data on the label issued from the printer 1 of the present apparatus is suitable for issuing a label of certain predetermined data on a certain article 22.

Various members are mounted on the frame 2 of the printer 1, and these various members can move up and down together with the frame 2. That is, the lifting and lowering of the entire frame 2 can be freely adjusted according to the height of the article placed and conveyed on the conveyor 20. It is roughly classified from these various members, the sensor 3 for article detection, the pulling roller 5 of the tape-shaped mount 8, the stock member 10 holding the excess label issued from the printer 1 and the tape-shaped mount 8 are turned over,
Peeling portion 1 for peeling the label 9 temporarily attached on the mount
8, a sticking roller 19 and the like for sticking the peeled label 9 to the article 22.

More specifically, the sensor 3 is connected to the motor 4 for driving the pulling roller 5 and is set so as to face the conveyor 20, and when the article 22 conveyed on this conveyor 20 is detected, the pulling roller 5 A signal for driving the tape-shaped mount 8 is output to pull the tape-shaped mount 8, and the pulling roller 5 is provided with a pressure contact roller 6 so as to sandwich the tape-shaped mount 8.

Next, the stock member 10 is a member for temporarily stocking the label issued from the printer 1. To be exact, the issued label is in the longitudinal direction on the tape-shaped mount 8.
It means a label continuum 7 in which predetermined data is printed on the labels 9 which are temporarily attached at equal intervals, and are issued labels.

As shown in FIGS. 2 to 4, the details of the stock member 10 include a pair of operating rollers 14 and 15 at both ends of a stay 11, which is a supporting member mounted on the frame 2 of the printer, and roller shafts 13a and 13b. The label continuum 7 which has been issued is suspended between the pair of actuating rollers 14 and 15 by
It is a seesaw system that can swing around 11 fulcrum shafts 12.

Further, a tension spring 17 as an urging member is attached to one end of the stay 11, and the stock member 10 is viewed from the printer 1 side as a whole to extend the transfer path length of the label continuum 7 to be issued. (Label feeding direction)
This is presented as an inclined state (see FIG. 2).

Further, a detector 16a such as a micro switch connected to the printer 1 facing the stay 11 is installed. That is, the detector 16a opposite to the roller shaft 13a is
ON, O depending on the stock status of the label on stock member 10
In the tilted state of the stay 11 shown in FIG. 2 in which the label is maximally stocked, the roller shaft 13 pushes it to turn it off and the printer 1 stops issuing the label (detected by the operating roller 14). (The tip of the container 16a comes into contact), while the label sticking operation that feeds out the label is performed and the stay 11 tilts gradually, the roller shaft 13a retracts to turn it on.
Then, the printer 1 is set to start label issuance (the tip of the detector 16a is separated from the operating roller 14).

Next, at the bottom of the stock member 10, there is a peeling portion 18 for the label 9.
And a sticking roller 19 for sticking a label to the article 22 is mounted on the frame 2.

Next, the operation of this device will be described with reference to FIGS.

First, when the sensor 3 detects the article 22 mounted on the conveyor 20 shown in FIG. 1, the motor 4 is driven to rotate the pulling roller 5. Therefore, since the tape-like mount 8 sandwiched between the pair of rollers 5 and 6 is pulled, the stock member 10 holding the label continuous body 7 printed by the printer 1 has a transfer speed from the state shown in FIG. Due to the rapid application of the label to the article 22, the label continuum 7 is displaced in the direction of the state shown in FIG.

As shown in FIG. 2, the stock member 10 which has already been printed, that is, the label continuum 7 is in an excessive holding state, the tension force of the tension spring 17 causes the pair of actuating rollers 14 and 15 to label the label. It is in a state of being inclined in the feeding direction.

Since the tape-shaped mount 8 is pulled by the rotation of the pulling roller 5 so as to be displaced from this state in the direction of the state shown in FIG. 3, the already-printed surplus holding label 9 is peeled off by the peeling section 18. And is fed to the bottom surface of the sticking roller 19.

That is, the stock member is pulled by pulling the tape mount 8.
The label continuum 7 suspended on 10 is inverted at the peeling section 18, and the label 9 temporarily attached on the tape-shaped mount 8 is peeled off, and the article 22 mounted on the conveyor 20 arrives there. The peeled label 9 is stuck to the article by the sticking roller 19 by the sprinkling action.

Next, when a label is attached to the article, a pair of rollers is attached.
Since a part of the label continuum 7 suspended between 14 and 15 is paid out, the stock member 10 sequentially rotates counterclockwise around the fulcrum 12 against the tension spring 17 to continuously advance the label continuation. When the length of the transfer path of the body 7 is minimized and the label stock is swept out, the state shown in FIG. 3 is obtained.

The limit switch, which is the detector 16a, is the stock member 10
Is turned on as the transfer path length of the label continuum 7 is expanded from the maximum expanded state to the contracted direction, the label issuance signal is output to the printer 1, and the label of the next stage is predetermined. To print. That is, when there is no surplus of the issued label on the stock member 10, the label issuing signal is output to the printer 1.

Then, the label of the next stage is issued, and the stock member 10 is sequentially rotated in the clockwise direction as shown in FIG. 4 by the action of the tension spring 17 to return to the state of FIG.
It takes some time to completely restore the stock of the issued label, and at this time, the label sticking to the article 22 is temporarily stopped.

The reason why the stock member 10 is displaced from the state shown in FIG. 2 to the state shown in FIG. 3 is that the convey speed of the article 22 by the conveyor 20 is faster than the label issuing speed by the printer 1. In the state shown in FIG. 3, the stock member 10 is turned counterclockwise to the maximum, the transfer path length of the label continuum 7 is shortened most, and the label stock is swept out. Therefore, the state is used as the displacement of the roller shaft 13b. A detector 16b for detecting correspondingly is provided,
When the state is detected, the conveyance of the article 22 by the conveyor 20 is temporarily stopped.

(Effects) According to the automatic label sticking apparatus of the present invention, the label continuum 7 is suspended between the printer 1 and the label sticking roller 19 and is oscillated around the fulcrum. A label stock member 10 comprising at least a pair of actuating rollers 14 and 15 for expanding and contracting the transfer path length, and the stock member 10 is elastically attached in a direction in which the transfer path length of the label continuum 7 is extended (label feeding direction). When the urging biasing member 17 and the stock member 10 are in a state where the transfer path length is extended to the maximum, the label issuance is stopped, and it is detected that the printer is displaced from the extended state in the contracting direction. Since the structure is provided with the detector 16a which outputs the label issuing instruction signal, the number of sheets is limited, but the excess label can be retained in the stock member. Therefore, it is possible to continuously attach the label to the article, although the number is limited.

Further, the stock member 10 provided with the swingable actuating rollers 14 and 15 is not limited to the vertical direction or the like as in the conventional stepped roller system, so that it has versatility and various automatic label sticking devices. It is applicable and practical.

In addition, since the label issuing speed is slower between the label issuing speed in the printer and the transfer speed of the goods on the conveyor, the issued label is forcibly pulled when the label is applied, and printing defects occur. Since the label is stocked in a certain amount, it is possible to prevent the pulling action of the label and prevent printing defects.
