The present invention relates to a technique for attaching a label to an adherend covered with various materials such as paper, resin, glass, and metal, and more particularly, to remove a defective label, which can be a labeling machine that accurately extracts only a defective label immediately before attachment. It is about a device.

In a labeling machine equipped with a roll label, a label produced by removing the tape from the roll label and cutting the tape to a predetermined length with a cutter device is attached to various adherends.

In either the roll label method or the sub label method, a date, a product code, a load number, etc. may be printed on the label immediately before the label is attached to the adherend.

By the way, there is a seam of a tape in a roll label, and since the label of a joint part is a bad label, it is not possible to put it on the market attached to a to-be-adhered thing.

At present, the above-mentioned defective label processing method includes arranging detection means for detecting the presence or absence of a defective label in the transport path of the adherend to which the label is adhered, and pickup means for selectively removing the deposit from the transport path.

(4) On the back side of the seam of the tape, a colored tape for identification is applied in advance, and the pick-up means collects and extracts a specific adherend by receiving a read signal of the colored tape from the detecting means of the labeling machine.

When collecting and extracting the adherend to which the above-mentioned bad label was attached, the operation speed of a labeling machine is decelerated.

In order to keep up with changes in the operating speed of the machine, the conveying line on the side supplying the adherend must be designed with a long length with a margin, and a large installation space is required.

(5) In the market, there is a request for high speed operation of a labeling machine, but when the operating speed of the labeling machine becomes high, it is technically difficult to collect and extract the adhered material with a bad label.

Therefore, the current bad label processing technology is one of the major obstacles in promoting the high speed running of the labeling machine.

This invention is made | formed in view of the above point, and the objective is to provide the following defective label removal apparatus.

The following describes how to remove a defective label.

(1) Labeling

In FIG. 1, the label supplied from the label supply means 10 can be exchanged on the outer circumferential surface of the transfer drum 20, and the label adsorbed by the negative pressure on the outer circumferential surface is transferred toward the attachment drum 30.

During the transfer, when the label passes through the printing device 60, date information, product number, load number, and the like are attached to the label surface.

The printed label can be exchanged from the transfer drum 20 to the outer circumferential surface of the attachment drum 30, and the label adsorbed by the negative pressure on the outer circumferential surface is transferred toward the adherend 40 supplied by the conveying means 50. do.

During the transfer, after the label passes through the adhesive supply means 61, the adhesiveness is imparted to the back surface of the label, the label meets the adherend 40 and the label is attached to the adherend 40.

(2) monitoring of labels

The detection sensor 71 is adsorbed on the outer circumferential surface of the transfer drum 20 to monitor the presence of colored tape indicating the seam of the tape, such as date information, product number, rod number, etc., on the label surface on which the factor is completed.

The detection sensor 71 'provided around the attachment drum 30 monitors the presence of colored tape, which means a seam of the tape attached to the back of the label.

(3) Detection of bad label

The control part 80 monitors the part displayed by each label unit through each detection sensor 71, 71 ', and when it detects the passage of a defective label, the clutch which comprises the label extraction device 70 shown in FIG. A transmission control command for rotation is generated at 77 and a expansion / contraction control command is generated at the cylinder 79 at the same time.

At this time, the control unit 80 corresponds to the operating speed of the labeling machine, calculates a transfer time until the defective label reaches the label extraction device 70, and generates a control command.

(4) extraction of defective label

With the cylinder 79 being contracted under the control of the control unit 80, the advancing roller 76 is advanced until it comes into contact with the outer circumferential surface of the attachment drum 30 about the branch axis 76a, and the advancing roller When 76 is in contact with the outer circumferential surface of the attachment drum 30 about the branch support shaft 76a, the retraction roller 76 is retracted by the cylinder 79 extending operation.

When the retraction roller 76 is retracted once, the clutch 77 receives a control command from the control unit 80 to transmit the rotational force to the retraction roller 76, and the retraction roller 76 is at least as long as the label every minute. Rotate and stop

As a result, the land of the land roller 73 wound on the retraction roller 76 comes into contact with the back surface of the beginning of the defective label, and the defective label is forcibly detached from the outer circumferential surface of the drum 30. The defective label adhered to and adhered to is recovered to the winding table 75.

By the forward and backward movement of the advance roller 76 and the interruption of the clutch 77 provided in addition to the winding table 75, the rotational drive of the winding table 75 can be made at high speed and with good timing.

Therefore, even if the label feeding speed is high, the defective label can be extracted reliably and accurately.

In this way, when the defective label passes immediately before the retraction roller 76, the retraction roller 76 retreats and presses the site to the back of the defective label, and the winding table 75 winds the site by a predetermined length. In this process, the defective label taken out before attachment can be transferred to the site and recorded.

That is, when the bad label passes, the bad label can be extracted before attaching to the adherend 40, so that it is not necessary to lower the operating speed of the labeling machine at a low speed to extract the bad label, It is possible to reliably take out the defective label while operating the controller.

Thus, high speed running of the labeling machine can be promoted.

In addition, since the defective label can be extracted without changing the operating speed of the labeling machine, the line length of the supply path 51 constituting the conveying means 50 of the adherend can be shortened, and the overall size of the machine can be reduced. ， Lower cost can be realized.

By removing the defective label before attaching, the sticking drum 30 shown in FIG. 1 attaches only the normal label to the adherend 40.

In addition, since a defective label is selected, a label is not attached to the adherend 40 to be attached.

Since the adherend 40 to which the label is attached can be recovered and used as is to attach the label, the loss of the adherend 40 is eliminated.
