Description

[0001] Apparatus for Attaching Label [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates generally to a label attaching apparatus for attaching to a cell phone battery or the like, and more particularly, to a new label attaching apparatus for supplying a label in an accurately aligned state and being easily peeled off from a release sheet.

In general, a product completed by the manufacturing process may be shipped as a product after labeling to indicate product specifications or other precautions, or to display identification information such as a unique number. Attaching the label to the product by hand requires a lot of labor, time and effort, and it is disadvantageous that the productivity is deteriorated due to the error of the operator, the damage of the adhesive portion, and the like. Therefore, there is a technical need to automate labeling.

In order to meet such a demand, conventionally registered patent publications of "Automatic label separating and attaching apparatus", for example, Registered Patent Registration No. 10-0291445 (registered on Mar. 12, 2001) Discloses an automatic label separating and attaching apparatus capable of automatically attaching a label having a specification or date of manufacture on a product. This device was able to attach the label automatically by sucking up only the label on the label sheet continuously fed on the roll next to the conveyor where the electronic product is being conveyed, and then rotating and pushing it to the labeling side of the product. However, according to this configuration, the labels on the label sheet are separated from the release sheet on the label plate fixed at a specific position. While the label separated from the release sheet is standing on the label plate for a predetermined time, Lt; RTI ID = 0.0 > release < / RTI > Therefore, the label sheet fed on the roll has to be repeatedly moved and stopped intermittently, and this movement and stop are made by the rotation of the rollers, and it is difficult to precisely control the movement length by one label length There was a problem. Further, the label must be transported from the label plate to the article by the adsorption head, and because the article is being transported on the conveyor line, precise control is required to align the adsorption head and the article in line.

On the other hand, as another example of the related art, in the registration publication of the "labeling device" of the Korean Patent Registration No. 10-1200783 (registered on Nov. 07, 2012), the label supplied from the labeling portion is sucked or unloaded from the sucking device, Discloses a label attaching apparatus that attaches a label by causing the suction device to rotate linearly on a product in a standby state after the rotary drive unit is rotated so that the label is brought into close contact with the product surface. By the way, according to this configuration, the label supplied from the label transfer section is directly adsorbed or dispensed using the suction device without any separate separation structure. However, in general, the label is supplied attached to the release paper. Although the adhesion between the release paper and the label is weak, it is nevertheless disadvantageous in that a strong adhesion force is required to adsorb and peel the label attached to the release paper there was.

Therefore, there is still a need in the art for an apparatus for attaching a label, which allows the label to be easily peeled off from the release paper and to simplify label transfer control.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above and to provide various additional advantages, and in particular, to provide a new label attaching device for supplying a label in an accurately aligned state using a simple structure, And to provide the above-mentioned objects.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A labeling apparatus or labeler 10 provided in accordance with an aspect of the present invention is a labeling apparatus or labeler provided on a label sheet LS on which a plurality of labels L are attached on a release sheet S in the form of a continuous sheet, And attaches the label L to the label attaching position P3 of the product A and is provided with a label feeder 14, a label attacher 12, and a product feeder 16.

The label feeder 14 supplies a label in the form of a label sheet LS, as illustrated in Figures 1, 2, 3, 5 and 6, wherein the label sheet LS is in the form of a long continuous sheet A plurality of predetermined types of labels L are successively attached to one surface of the release paper S of the recording medium. Such a label sheet LS can be fed while being rolled up in the form of a roll loaded on the label sheet feed roll 141 and loosened. The label sheet LS wound on the label sheet feed roll 141 can be continuously fed in a state where the label feed table 143 is advanced (in the -X direction in Fig. 1) when it is unwound and stopped when it is reversed. The label sheet LS released from the label sheet supply roll 141 is held in contact with the upper surface of the label supply table 143 while the tension is maintained via the direction switching roller 142, And is wound around the table roller 144 at the leading end to maintain a constant tension. The release paper S is conveyed to the table roller 144 by the driving roller 148 driven by the roller driving unit 149 via the direction switching roller 147 And can be discharged to the outside. It is sufficient that the power applied to the driving roller 148 by the roller driving unit 149 does not reach the degree that interferes with the movement of the feeding table 143 but only the force enough to cause the releasing paper S to be smoothly discharged.

Particularly, according to the present invention, the label L supplied from the label feeder 14 is fed by the advancing and reversing (X direction) of the label feeding table 143. The label feeding table 143 can repeat the advancing and reversing operations by the operation of the actuator 145.

The label feeding table 143 advances each label L on the label sheet LS to the predetermined label feeding position P1 and moves the label L in the label feeding position P1, Can be moved backward by or longer than the length of the label L so as to be peeled off from the releasing paper portion immediately below it.

The label applicator 12 may have a vacuum adsorber 120 that is vertically movable and horizontally movable, as shown in FIGS. 1 and 3 as a side view and as illustrated in a front view in FIG. The vacuum adsorber 120 is a means for adsorbing the label L and releasing it from the release paper and attaching it to the product.

The vacuum adsorber 120 is configured such that when one label L arrives at the label supply position P1 by the label supply table 143 the label L at the label supply position P1 from the standby position P2, So that the label L is adsorbed. The vacuum adsorber 120 adsorbs the label L and at the same time the label supply table 143 is moved backward. The label L is attracted to the lower end surface of the vacuum adsorber 120 while the portion just under the release paper is wound on the table roller 144 of the label supply table 143, 143, so that the label L can be released from the portion of the release paper just under the label L, and at the same time, be adsorbed on the vacuum adsorber 120. Thereafter, the vacuum adsorber 120 again rises to the original standby position P2, and sequentially moves to the product attaching position P3 and is brought into close contact with the product, so that the label can be attached to the product.

The label applicator 120 includes a vertical movement driver 121 and a vertical movement guide 122, a connection frame 123, a horizontal movement driver 124, a horizontal movement link 122, A horizontal movement guide 125, a horizontal movement guide 126, and a support frame 127.

The vacuum adsorber 120 can be moved up or down along the vertical movement guide 122 by the driving force applied by the vertical movement driving unit 121. The vertical movement of the vacuum adsorber 120 causes the lower end surface of the vacuum adsorber 120, The surface can reciprocate between the label feed position P1 and the standby position P2.

The vertical movement driving unit 121 and the vertical movement guide 122 are fixed to the horizontal movement driving unit 124 by the connection frame 123 together with the vacuum adsorption unit 120. The connection frame 123 is fixed to the support frame 127 so as to be horizontally movable. The fixed frame 127, on the other hand, is fixed to the base frame of the labeler 10 and provides a reference for the movement of the vacuum adsorber 120. The horizontal movement driver 124 may pull or push the horizontal movement link 125 to cause the vacuum adsorber 120 attached to the other end of the horizontal movement link 125 to move horizontally along the horizontal movement guide 126 .

In this way, the vertical movement drive unit 121 and the horizontal movement drive unit 124 operate simultaneously, so that the vacuum adsorber 120 can move in the plane along the vertical movement guide 122 and the horizontal movement guide 126, , And can reciprocate from the standby position P2 to the label attaching position P3.

The product feeder 16 is a device that feeds the product A to the label attaching position P3 and includes a fixed jig 164 and a driving device for moving the product A on the jig 164 A product supply unit 162 may be provided.

Two label position sensors 150 and 151 may be provided to ensure that the label L arrives precisely in the label feed position Pl, as illustrated in Figures 2 and 3. The two label position sensors 150 and 151 can detect that the two-dimensional label L arrives at the label feed position P1 in the correct posture and transmit the detection information to the actuator 145 or the like. Specifically, the label position sensors 150 and 151 may be sensors that sense that the label L has arrived at a predetermined and predetermined position in the longitudinal direction and the width direction.

Thus, according to the present invention, the label L moves via three different positions. That is, to the label feeding position P1, then sucked and moved to the standby position P2, and then to the label attaching position P3 to be attached onto the product A. The movement of the label L between the three different positions is performed by the label applicator 12. Therefore, it is preferable to configure the three positions to be on one plane, since the configuration of the label applicator 12 can be simplified.

According to the labeler 10 having the above-described configuration, the labeling step 700 shown in FIG. 7 can be performed. The label sheet LS is first unwound from the label sheet feed roll 141 by one label length and the label sheet LS is placed on the label supply table 143 (L) may be advanced to the label feed position P1 and aligned (720) to a predetermined position. Then, when the vacuum adsorber 120 is lowered 730 from the standby position P2 to adsorb the label L 740 and at the same time the label supply table 143 is moved backward, the label L is removed from the release paper S Peeled (740), and adsorbed to the vacuum adsorber (120) (760). When the product supply unit 162 supplies the product A to the label attaching position P3 in step 770, the vacuum adsorption apparatus 120 moves to the label attaching position P3 to move the label L to the product A (780).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art. Therefore, it should be pointed out that the scope of the present invention is not limited to the described embodiments, but should be construed according to the appended claims.
