The objects, features and advantages of the present invention described above will become more apparent through the following detailed description. Hereinafter, a preferred embodiment of the present invention will be described based on the accompanying drawings.

1 to 6 show a preferred embodiment of the present invention. As shown in Figure 1, the labeling system 10 of the present invention is to automatically attach the label 12 to the correct position in the process of continuously supplying the box-shaped skin attachment 11, in a straight line. An extended conveyor 20 is provided, and the height sensor 28, the under camera 30, and the conveyor 20 for acquiring information about the skin adhesion 11 along the longitudinal direction of the conveyor 20 are progressed. Alternatively, an encoder 33 for measuring length or displacement by counting pulses according to rotation is positioned, and a label feeder 50 that continuously provides labels 12 to the rear end of the under camera 30 and this label A pickup means 40 for adsorbing the label 12 from the feeder 50 and attaching it to the skin complex 11 is provided.

In addition, a pressure roll 60 is provided at the rear end of the pickup means 40 to completely press and closely adhere the label 12 attached to the skin adherend 11 in the previous step, and on one side of the conveyor 20 A controller 15 is provided to control the operation of the device including the pickup means 40 according to the information of the skin attachment 11 by the height sensor 28 and the under camera 30, which is shown in FIGS. It will be described in detail with reference to FIG. 6 as follows.

As shown in FIG. 2 , the conveyor 20 includes a screen belt 21 that is transported in a state in which the skin attachment 11 is seated, and guide walls 22 that are raised on both sides of the screen belt 21 , etc. The screen belt 21 is provided with a light-transmitting mesh, etc., so that the shadow for the skin complex 11 placed on the upper surface can be confirmed from the bottom.

In addition, the height sensor 28 is installed on the gate frame 27 extended to the upper part of the conveyor 20 to detect the height of the skin complex 11 progressing downward, and the under camera 30 is located in the lower part of one side of the conveyor 20 to photograph the skin complex 11 on the screen belt 21 from directly below to the upper side, and the screen belt 21 has a shadow of the skin complex 11 at the bottom By the under camera 30 according to the reflection on the skin complex 11 is possible to take a bottom surface.

In photographing the bottom of the skin attachment 11 by the under camera 30, a photographing booth 31 is formed on the conveyor 20, and the photographing booth 31 is a casing to form a photo zone of a certain area. and a backlight 32 to illuminate the light corresponding to the photographing position of the under camera 30 is built-in, and this photographing booth 31 has a dome to minimize reflection efficiency of lighting or unnecessary shadow generation. that can take shape.

In addition, when the under camera 30 is installed under the conveyor 20, the screen belt 21 is provided to prevent shooting in a double-layered state to increase the accuracy of shooting. 21 is configured such that the loading part 23 on which the skin attachment 11 is seated and the return part 24 operated in a no-load state are continuously circulated, and the return part 24 includes a plurality of tension rollers 26a~ 26d) is formed so as to be diverted to the lower part of the under camera 30 .

As shown in (a) of Figure 3, as the screen belt 21 is provided to be light-transmitting as described above, the shadow for the skin complex 11 placed on its upper surface can be confirmed from the bottom. , this makes it possible to photograph the bottom of the skin complex 11 attached to the screen belt 21 by the under camera 30 located under the skin complex 11 .

In this way, when information on the size and shape is acquired using the shaded area 16 of the skin complex 11, the distortion of the subject by the camera or the lens itself or the shadow generated by external lighting are excluded during the photographing process. It is possible to accurately capture the actual area of the complex 11 .

Also, as shown in (b) of FIG. 3 , in reality, each skin complex 11 on the conveyor 20 has various postures and behaviors when the width of the screen belt 21 is relatively larger than that of the skin complex 11 . It can be randomly transferred to the location, and even in this case, the present invention can accurately acquire information about the skin complex 11 of various standards by the height sensor 28, the under camera 30, and the encoder 33. there will be

Specifically, by the height sensor 28 and the camera 30, the height and planar area of the skin complex 11 are measured and at the same time the seating posture or position of the skin complex 11 is measured, and the encoder ( 33) confirms the moving position for the skin complex 12, and the height sensor 28, the camera 30, and the encoder 33 by the controller 15 determine the pickup to be described later according to information. The label 12 is attached on the upper surface of the skin complex 11 by controlling the vertical position, the planar position, the posture or the angle of the means 40, which will be described with reference to FIGS. 4 and 5 as follows.

As shown in FIG. 4 , the pickup means 40 is a pickup arm in the form of a multi-joint on the support frame 41 extended to the upper portion of the conveyor 20 so as to be positioned on the path of the skin complex 11 . (42) and a rotator (46) capable of rotating the pickup arm (42) at a predetermined angle are coupled, and a suction head (43) capable of adsorbing the label (12) to the lower end of the pickup arm (42) ) is installed. Here, the pickup arm 42 connects a plurality of links 44 and 45 so that it can be moved up and down and left and right and rotatably operated by the rotator 46 at the same time, so that the conveyor 20 ) adsorbs the label 12 from the label feeder 50 disposed on the side of the label 12 to accurately attach the label 12 to the upper surface of the skin complex 11 that is randomly transferred to various postures and positions as described above. do.

On the other hand, on one side of the pickup means 40, a label confirmation camera 54 that can confirm whether the label 12 is accurately picked up may be installed, and the label confirmation camera 54 is a label feeder to be described later. It is located close to (50), which will be described with reference to FIG.

As shown in FIG. 5, label feeders 50 may be provided on the left and right of the pickup means 40 as described above, and the label feeders 50 are continuously supplied from the feed roll 51. (12) is detached from the rear film by the separator (52) and can be individually seated on the standby bed (53). A plurality of these label feeders 50 are arranged in the left and right and front and rear within the operating radius of the pickup means 40 to increase the supply or adhesion speed of the label 12 to increase productivity, and the pickup means 40 is The label 12 is adsorbed on the pickup head 43 and the position is confirmed by the label confirmation camera 54 .

On the other hand, although the label 12 is attached to the correct position on the upper surface of the skin attachment by the pickup means 40 as described above, in this case, the pickup means 40 is labeled by a sufficient pressing force due to the nature of its operation. Since there may be a limit in adhering the entire surface of the 12 to the skin attachment 11, for this purpose, the rear end of the pickup means 40 has a pressure roll ( 60) is provided, which will be described with reference to FIG. 6 as follows.

As shown in FIG. 6 , the pressure roll 60 is positioned above the progress path of the adherend 11 and is operably provided up and down by a cylinder 61 , etc., by such a pressure roll 60 During the continuous process of the skin complex 11, the label 12 is pressed into close contact to enable complete attachment, and it is repeatedly lifted and lowered according to the interval of the skin complex 11, such as the speed of the skin complex 11, etc. Pressurization operation is possible without interference as much as possible.

Reference numerals not described above indicate the main roller 25 of the main frame 13 and the conveyor 20 in which the device is installed.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and it is common in the technical field to which the present invention pertains that various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention.
