The present invention relates to a label applicator using a release paper, and more particularly, to a label applicator using a release paper that can attach a label to the fruit conveyed by the conveying means.

In general, a variety of devices and methods for labeling an article are disclosed, including one that includes an air spray between the labeling means and the article to attach the label.

As a technology incorporating such an air injector, New Zealand Patent No. 206,735 discloses a labeling device having a rotating head. Here, the release paper to which the label is peeled off is wound on the drum, and the release paper is peeled off and wound up by the vacuum of the blower at the end of the label while moving along the end of the flat plate. When the blower is in close proximity to the article to be labeled, the vacuum is shut off, the air blowing is blown to attach the label to the article, and retracted and rotated to receive another label.

On the other hand, New Zealand Patent No. 129,825, which attaches a label by an air spraying device, includes a flat knife for peeling off the release paper of the label, and a spatula box for winding the release paper by suction by vacuum force. The article must then be placed under the spatula box and includes control of the microswitch to sequentially supply high pressure with sufficient force to attach the label to the article.

There is also a portable labeling machine that can be sprayed or held. This labeling machine uses one or more spatula suction pads to remove the release paper attached to the label.

New Zealand patent 241,050 discloses means for labeling articles in more various ways. A device for attaching labels at high speeds, which includes a vacuum drum for cutting and unwinding labels wrapped in a cylindrical body. The vacuum drum includes a vacuum port for wrapping the label on the drum, and an air jet is used to attach the label. The airjet effectively moves the label and effectively dries the label attached to the article.

However, these prior arts have many problems for continuously attaching labels to articles. For example, New Zealand Patent No. 206,735 requires a blower that produces a particular vacuum force. In other words, the vacuum generator and the blower should be moved to a close position so as to wind up the label at the proper position and attach the label to the object.

In addition, the vibration of the blower to generate the vacuum force is a problem that may affect the operation of the peripheral device as described above.

On the other hand, the article for labeling is a fruit that can be easily broken and can damage unwanted fruit between the surface of this fruit and the label attached by the whirling.

In addition, the blower must be operated continuously on the fruit passing under the blower, and passed under the fruit to continuously label. That is, only one label can be attached to one article in one operation.

In addition, an apparatus used for a label applicator instead of an air spray apparatus requires a separate vacuum apparatus, and a separate airjet for attaching a label in vacuum over an object passed under the vacuum apparatus is required. Thus, a separate vacuum must be formed in order for such a device to be driven, and the creation of a separate vacuum for this device to be driven is similar to the above design.

A device for generating a vacuum force by an independent vacuum device or a device for attaching a label at a high speed. A label is used to transport a label instead of a vacuum port, to cut a label to be released from a drum, and to separate a label end from a container. You need strength. This device also has a similar problem.

On the other hand, a portable labeling machine also has a problem. In other words, the speed of labeling varies depending on the individual user. In addition, the number of labels that can be attached at one time is limited depending on the article.

The present invention is to solve the above problems, an object of the present invention is to provide a labeling device using a release paper that meets the following performance of the device for attaching a label to one or a plurality of articles.

a) Be able to attach the label at high speed. b) be able to label one or more objects in succession. c) There should be no cutting device, vacuum device, air jet device, attachment device, etc. and simple. d) Label the object at the same time as its speed of movement, its complexity, and its structure. e) The object must be detected and operated regardless of the location of the gathered items.

The present invention is a label attaching machine for separating a label from a label paper attached to a release paper at regular intervals and attaching it to an article, wherein the label drum (4) is wound on the label drum (5), and the label drum (5) A drive wheel 10 and a pressure wheel 11 for withdrawing the wound label paper 4, and a start portion of the label 2 on the label paper 4 through the drive wheel 10 and the pressure wheel 11; An optical sensor 12 for detecting an end portion, and a separator 13 for separating the label 2 adhered to the label paper 4 by bending the label paper 4 passing through the optical sensor 12 at an acute angle; A detection signal at the beginning of the label 2 by the optical sensor 12 between the label 2 and the article 3 located at the bottom of the label 2, which begins to separate through the separator 13. The injection nozzle 15 operative to form the air curtain 18 by means of a detection signal at the end of the label 2 by the optical sensor 12; The label 2 by the optical sensor 12 is operated to stop the operation of the bla 15 and to attach the label 2 separated through the separator 13 to the article 3 with a constant blowing force. It characterized in that it comprises a blower 19 which is stopped by the start detection signal of the.

In addition, the present invention is characterized in that the label (2) is further configured to comprise a release paper drum (14) wound to recycle the release paper (6) separated.

Hereinafter, with reference to the accompanying drawings will be described in detail a label attaching machine using a label with a release paper according to an embodiment of the present invention for applying a label to the article. In adding the reference numerals to the components of the drawings, the same components are to have the same reference numerals as much as possible even if displayed on different drawings, it is known that it may unnecessarily obscure the subject matter of the present invention Detailed description of functions and configurations will be omitted.

1 is a perspective view of a label attaching machine using a release paper according to an embodiment of the present invention, Figure 2 is a schematic configuration diagram of a label applying machine using a release paper according to an embodiment of the present invention, Figure 3 is one of the present invention 4 is a plan view of the blower in the labeling machine using a release paper according to the embodiment, Figure 4 is a side view of the injection nozzle in the labeling machine using a release paper according to an embodiment of the present invention, Figure 5 is a release paper according to an embodiment of the present invention An explanatory view of the label is separated from the labeling machine using.

The process for supplying the label 2 to the article 3 can be carried out in two ways. That is, the article 3 is detected by an optoelectronic sensor (not shown) or a signal is received from a host computer (not shown). The labeling machine 1 of the present invention is operated by a separate sensor device which is interlocked with the host computer, the host computer, or equipped with an optoelectronic sensor for detecting the article 3.

An article detector for detecting the article 3 is mounted on the bottom of the labeling machine 1 and synchronized by a counter on the electronic control circuit to determine the location of the article 3 and the presence or absence of the article 3, Among the articles of, the label 2 detects a particular article 3 around the attachment point 7 to attach to the particular article 3.

The label applicator 1 of the present invention includes a label feeder, and the label feeder is supplied by a label drum 5 on which the label paper 4 is wound, and the label paper 4 is attached to the release paper 6 and adhesive. However, the label paper 4 is attached to the release paper 6 so that it can be easily separated. In other words, the label applicator 1 of the present invention operates to move the label paper 4 from the label drum 5 to the article 3 and to supply it to the attachment point 7 to which the label 2 is attached.

The sensor means may be an optical sensor 12 mounted on the movement path of the label paper 4 moving toward the attachment point 7 and capable of monitoring the position of the article 3 to which the label 2 is to be attached, Stepping motors not shown in Figs. 1 and 2 can be used. In the case of the stepping motor, there is an advantage that the error of the label attachment position can be greatly reduced, and there are many known techniques for such means. For example, it may be composed of a stepping motor, a driving wheel, a pneumatic device, a hydraulic device, a reduction device.

The label 4 is precisely moved to the attachment point 7 by the drive mechanism 8. The drive mechanism 8 includes a plurality of pulleys or idlers 9 to move the label 4 and is attached by a pressure wheel 11 that compresses the label 4 to an appropriate pressure. It is fed to the point (7), and through the separator 13 to be described later to allow the label (2) from the release paper 6 to be more easily separated. In addition, the driving wheel 10 is preferably configured to withdraw the label 4 from the label drum 5 while pressing the label 4 together with at least two pressure wheels (11). The pulley or idler 9 may be in the form of a wheel or cylinder.

The drive wheel 10 is driven by a stepping motor, not shown, and supplies the label paper 4 to the attachment point 7. The drive wheel 10 is also driven until one label 2 passes through the optical sensor 12. In other words, the label 2 is wound on the label drum 5 in a state where the label 2 is attached to the release paper 6 with an adhesive, and the driving wheel 10 and the pressure wheel 11 through the plurality of idlers 9. The label 2 of the release paper 6 to be supplied therebetween is supplied to the attachment point 7 while detecting by the optical sensor 12.

The attachment point 7 is configured to include a separator (13). The label paper 4 causes the label 2 to be gradually separated from the release paper 6 at the end of the separator 13 by the separator 13. That is, as shown in FIG. 5, the release paper 6 to which the supplied label 2 is adhered is shifted by 180 degrees from the separator 13 in which the tip portion is sharply formed, so that the label 2 is release paper ( Gradually separate from 6).

The label 2 separated from the release paper 6 at the attachment point 7 is firmly attached to the article 3 by the blower 19. In other words, the label 2 separated through the separator 13 attaches the label 2 to the article 3 by the blowing force of the blower 19.

4 is a side view of the injection nozzle 15, with a plurality of injection holes 16 arranged in a line along the injection nozzle side 17. At this time, the number and position of the injection holes 16 can be appropriately formed according to the case as known in the art. The injection nozzle 15 injects air between the label 2 and the article 3 that begin to separate from the label 4 to form an air curtain as shown at 18 in FIG. 2. In other words, the label 2 separated from the release paper 6 forms an air curtain at the bottom of the label 2 so as to be in equilibrium with the label 4.

The air curtain 18 formed by the injection nozzle 15 prevents the label separated from the release paper 6 from re-adhesive, like air across the label 2, like a flute.

The blower 19 is an end portion of the separator 13 which is easily separated from the release paper 6 by the tension force of the label 2 generated when the label paper 4 forms a curved surface while passing through the tip of the separator 13. Located in

When the end portion of the moving label is detected by the optical sensor 12, the air curtain 18 by the injection nozzle 15 is stopped, the blower 19 is operated.

As shown in FIG. 3, the bottom surface of the blower 19 is provided with a plurality of injection holes 16 so that air is directly directed downward, as in a miniaturized sour nipple. Accordingly, the air passing through the blower 19 forms a flow as shown by reference numeral 20 of FIG. 2. The air formed from this blower 19 causes the label 2 to adhere onto the article 3. In other words, when the blower 19 is driven by the blower 19 to attach the label 2 to the article 3, the start of another label 2 is detected by the optical sensor 12. The injection nozzle 15 is operated again, and at the same time the blower 19 stops its operation.

The blower and air nozzle are operated by five port valves, and the meshed air injector can be operated by a separate air compressor, as is known in the art.

The label paper 4 is separated through the separator 13, and the release paper 6 passing through the attachment point 7 is wound on the release paper drum 14 and reused. That is, the used release paper is wound on the release paper drum 14 by a low power, low speed motor (not shown) and recycled.

In addition, the tensile force for the release paper 6 to be wound on the release drum 14 is generated by a plurality of pulleys or idlers 9 and the pressure wheel (11). The pressure of the pressure wheel 11 is generated between the pressure wheel 11 and the drive wheel 10.

As described above, a large number of repetitive operations are performed to supply the label 2 to a large number of articles 3 for labeling. The labeling device of the present invention can easily attach a label to the irregular article 3, and can easily improve the speed of attaching the label. In addition, the present invention can attach a label to an article to be fed continuously, or can easily attach several labels to an article.

The present invention may use a soft steel frame or pulley, but may use various materials such as aluminum or plastic that can form a sufficient tensile force by the pressure wheel or the driving wheel.

According to the present invention, it is possible to attach a label at high speed, and to label one or more articles in succession.

On the other hand, the present invention is simple, there is no cutting device, vacuum device, air injection device, attachment device, etc., there is an advantage that can be attached to the label at the same time, the complexity of the structure, the object.
