Description

[0001] APPARATUS FOR INSPECTION OF LABEL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label inspecting apparatus, and more particularly, to an apparatus for inspecting a defect in a label attached to a product or a package so as to identify the product or display information on the product.

The label attached to the product or package indicates the name of the product, the manufacturer, the date of manufacture, the serial number, and the like. Such a label is printed on a label paper extending long and wound into a roll shape, and then supplied to a use place of the label.

Since these labels display important information about the product, the information should be displayed correctly, but the printing of the label may fail to print certain labels.

If these prints are supplied to the user with a roll wrapped with bad labels, bad labels may be attached to the product, so the label should be printed after printing.

Inspection of these labels is done by wrapping a roll-wound label between two shafts, then unfolding the labels from one shaft and rewinding them in the form of a roll again on the other shaft, visually confirming the label placed between the two shafts To find the defective label, remove the label from the roll of the label, or mark it on the label.

Printing and roll-up of the label are performed quickly through an automated printing process and a winding process. However, since the inspection of the printing state of the label is performed by the naked eye, a considerable amount of time and labor is required for such inspection process, It is the most costly and time-consuming process in the manufacturing process.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device for automatically inspecting a label supplied in a roll shape, identifying a badly printed label, and displaying a bad mark in consideration of the problems of the related art.

The above-described object of the present invention is achieved by a label inspection apparatus according to the present invention as follows.

The label inspection apparatus of the present invention comprises: A base mounted on the ground; A first shaft installed at one end of the base and configured to be rotated in one direction so that the label is wound and rolled so that the label is released; A second shaft installed on the base opposite to the first shaft for winding the label unwound from the first shaft into a roll shape; A servo motor for driving the second shaft; An illumination installed between the first shaft and the second shaft to illuminate the surface of the label released from the first shaft; A camera installed between the first shaft and the second shaft for photographing a surface of a label released from the first shaft; A standard image of the label is stored, and an image of the taken label is compared with the standard image to check whether the taken label is defective. If there is a defect in the taken label, a failure determination signal for the label ; And a defective display unit which receives a defective determination signal from the control unit and performs a defective display on the label determined to be defective.

According to the configuration of the label inspecting apparatus of the present invention, the roll wound and fed in a roll form is unwound from the first shaft and wound again in the form of a roller in the second shaft.

The label is thus unrolled and the printed state is inspected in the unfolded state, which is done by illumination and the camera. The illumination irradiates light to the label being released, and the reflected image of the irradiated light is photographed by the camera.

The standard image of the label to be inspected is stored in the control unit of the apparatus, so that if there is a difference between the image taken by the camera and the standard image, the label of the photographed image is judged to be defective.

The determined information is transmitted to the defective display unit, and a defect is displayed on the label before the label is rolled up on the second shaft.

The labels marked as bad in this manner are not recognized by the operator or the attaching device attached when the label is separated from the subsequent roll and attached to the product or package.

According to the structure and operation of the present invention, it is possible to reduce the cost and the time consumed by the visual inspection by automatically inspecting the printing defects of the label and automatically displaying the defective label.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a label inspection apparatus according to an embodiment of the present invention,
FIG. 2 is a flow chart showing a flow of label inspection in a label inspection apparatus according to an embodiment of the present invention.

Hereinafter, the configuration and operation of an embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a base 10 of a label inspection apparatus is provided.

The base 10 is provided with other elements constituting the label inspecting apparatus, and is placed on the inspection table or the ground. The base 10 is formed in such a form that the label 1 wound in a roll shape at one end is fed and the label is loosened at the other end and the label which has been inspected and defective is extended again to be wound again.

On one end of the upper surface of the base 10, there is provided a first shaft 20 on which a roll-wound label is mounted and released. And a second shaft 20 on which the label having the inspection and defective mark is rewound while being unrolled is provided on the opposite end. The second shaft 20 is integrally formed with a servo motor for driving the second shaft 20, and the outer case of the servo motor constitutes the second shaft 20.

The label 1 is unwound from the first shaft 20 and rewound on the second shaft 30 so that the movement of the label 1 and the image picking up between the first shaft 20 and the second shaft 30 The rollers 41 to 45 are provided.

The rollers 41 to 45 are all free to rotate so that the wrapped label is released so that the label is flattened for image display and defect display.

Two rollers 41 and 42 are provided on the side from which the label 1 is released from the first shaft 20 and three rollers 43 and 43 are provided on the side where the label 1 is wound again on the second shaft 30 To 45 are installed.

A vision zone 51 and a failure display area 52 are provided between the second roller 42 and the third roller 43. Although not shown in the figure, a camera and a light are provided above the label 1 laid out in the vision area 51 so that the light illuminates the label 1, and the image reflected from the label is reflected by the camera .

The data of the photographed image is input to the control unit 11 provided behind the base 10. The control unit 11 stores a standard image of the label being inspected so that the data of the image captured by the camera is converted into a standard image of the label If there is a difference between the data and the data, the label is determined to be badly printed.

On the other hand, the defective display area 52 is provided adjacent to the downstream side in the traveling direction of the label 1. A marker (not shown) is provided above the label 1 in the defective display area 52 for marking the defective label on the label judged by the control unit 11 to be defective.

The operation of the label inspecting apparatus according to the above configuration will be described with reference to a flowchart shown in Fig.

First, the label 1 held in a roll-like shape is attached to the first shaft 20, and the tip of the label is unlocked to move between the rollers 41 to 44, and then the label tip is mounted on the second shaft 30 (Step S1).

Next, the servomotor is operated to start winding the label on the second shaft 30. As a result, the label 1 is released from the first shaft 20 and transferred to the second shaft 30 (step S2).

As the label 1 is released, the camera installed in the vision area 51 takes an image of the label. The camera is a line scan camera, and photographs the label 1 on a predetermined length basis and transmits the photographed image to the control unit 11 (S3).

The control unit 11 compares the image from the camera with the stored standard image (step S4), and when a difference greater than the allowable difference is confirmed, the control unit 11 first sends a stop signal to the servo motor (step S5) The information of the display is generated and transmitted to the marker, and in a state where the feeding of the label 1 is stopped, the marker marks the indication of the defective on the defective label (step S6). When it is determined that the image from the camera is not different from the standard image, the transfer and shooting of the label continues.

When the marking time set in advance ends, the control unit 11 transmits the operation signal to the servo motor again, so that the servo motor is driven and the inspection is resumed (step S7).

When all the labels are wound on the second shaft 30 after the inspection is completed, the control unit 11 stops the servomotor and the work is completed by removing the label wound by the worker from the second shaft 30 (step S8 ).

On the other hand, the control unit 11 always monitors the load state of the servomotor. When the load is driven to a load less than the load value required for winding the roll to the servo motor, it is judged that the transported label is broken or the inspection is completed , And an alarm is issued to notify the end of work and the occurrence of an abnormal state.

A sensor for detecting the passage of the label 1 may be installed between the rollers 41 to 44. If the sensor can not detect the label, it may be recognized that the operation is terminated or the label is broken and an alarm is sounded.

As described above, one embodiment of the present invention has been described, and the present invention is not limited to these embodiments, and various changes and modifications may be made within the scope of the claims.
