Description

Buffering unit and labeling device using the same {Buffering unit and labeling device using the same}

The present invention relates to a buffering unit and a label attaching device using the same. More specifically, the present invention relates to a buffering unit and a label attaching device using the same. More specifically, it not only allows temporary storage of label sheets printed at high speed in a laser printer, etc., but also supplies the printed sheets in the previous process of attaching the sheets after storage. This relates to a buffering unit that can be supplied immediately when needed and a labeling device using the same.

A representative method of attaching a sheet in the form of a conventional label sheet is to attach a label using a label separation device and an attachment device at a predetermined location on the attachment object transported by conveyors and logistics movement between workers, etc. In the method, release paper is continuously supplied through a reel and fed by a driving roller, the label sheet is left to standby at the adsorption standby position, and the vacuum suction plate placed on top of the adsorption standby position is lowered to vacuum the label. After adsorption, it is transported and attached to the attachment target location through rotational and linear movements.

In this method, the label may be peeled off depending on the attachment standby position of the label, then aligned with the X and Y axes at the attach standby position, and then the label may be attached.

Another method is to adsorb and peel the label from the release paper at the same time, and then transfer the adsorbed and peeled label to the attachment location and attach it at a predetermined location.

As such, various label peeling and attaching technologies have been developed, but the current label peeling and attaching method is difficult to actively respond to the rapidly changing forms and characteristics of tablet batteries, such as laser printers. When printing labels at high speed, there is a limit to the high-speed peeling of the printed label, and if the release paper is peeled at too fast a speed when moving the release paper by the driving roller, the stopping position of the label may be distorted and the label may be bent. The incidence of defects such as sagging may increase.

This is closely related to the limit of productivity, and when reel-type labels wait for the attachment position after the label is peeled, a curl phenomenon may occur where the label curls due to the characteristics of the reel. When this phenomenon occurs, it is difficult to secure the exact position when aligning the labels, and accordingly, the accuracy of the attachment position cannot be secured, making the automated process difficult.

In addition, when paging a certain length depending on the memory capacity with a laser printer, labels must be attached to the product sequentially, but the label attachment speed and printing speed do not match, resulting in a backlog of printed labels. In order to prevent damage, the label had to be attached to the product in a separate process after storage in advance, which had the drawback of making the automated process difficult.

When (1450) moves to the rear of the upper and lower rollers (1420 and 1430), the label sheet supplied from the buffering unit 1300 is guided by the upper and lower rollers (1420 and 1430) so that the label is not separated. It can be wound to the rear sheet recovery unit 1460.

In addition, the sheet separation unit 1400 includes a label border color sensor 1470 that detects the boundary between label sheets supplied from the buffering unit 1300 to one of the two side wall members 1410, and a label border color sensor 1470 that detects the boundary between the label sheets supplied from the buffering unit 1300, and ), a label color print detection sensor that detects the label sheet supplied from the buffering unit 1300, recognizes unprinted labels, and sends a detection signal to the control unit 1700 to control the cylinder 1440. (1480) is further installed.

Therefore, the label border color sensor 1470 detects the border between label sheets, and the label color print detection sensor 1480 recognizes unprinted labels, indicating that the border between label sheets is not properly printed or is not printed. When a label sheet is detected, a detection signal is sent to the control unit 1700 to move the sheet separation blade 1450 backward by the cylinder 1440, and then the label sheet is moved backward by the upper and lower rollers 1420 and 1430. Since the sheet is guided and the label is not separated but wound to the rear sheet recovery unit 1460, it is possible to prevent defective labels from being attached to the product.
