Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label pasting machine that intermittently peels labels that have been temporarily pasted onto a release mount from the mount and automatically affixes them to articles that are continuously transported. It is.

A label pasting machine that peels off labels that have been temporarily pasted onto a mount in a continuous manner from the mount, holds the peeled labels once, and affixes the labels onto articles to be transported using air or other means. However, there are various problems in accurately attaching a label to a predetermined position on an article transported by a conveyor device.

That is, when a peeled label is blown up from below and held by air, the holding position on the surface of the label holder may vary depending on the flow rate of air from the injection port of the high-pressure air blowing means.

In order to eliminate such problems, the present invention relates to a label pasting machine in which the label holder is provided with a stopper device for positioning the label tip at the end of the surface.

Hereinafter, the present invention will be explained in further detail based on the drawings showing an example of the present invention.

1 is a conveyor device for transporting article A; 2 is a label feeding device that temporarily attaches label a and feeds out a predetermined amount of backing paper 3 intermittently to a peeling position 4;
and a winding roller γ that winds up only the peeled mount.

8 is a printer that prints on the label a, and 9 is a peeling device, by which the mount 3 is turned over at the acute-angled end, so that only the label a is fed out horizontally.

10 is a high-pressure air source connected to two communication pipes 12 and 13 via a two-way switching valve 11, one communication pipe 12 communicates with a high pressure chamber 15 in the main body 14, and the tip of the other communication pipe 13. A high-pressure air blower located below the stripping device 9 communicates with the device 13a.

The main body 14 has a high pressure chamber 15 in the upper part and a label receiver surface 16 on the lower end surface, and a plurality of nozzle pipes 1γ opening from the high pressure chamber 15 to the label receiver surface 16 on the lower end surface are provided.

On the other hand, the label receiver has a stepped portion 18 formed at the end of the surface 16 opposite to the peeling device side, and a stopper piece 19 is fixed to the stepped portion by a screw 21 inserted into an elongated hole 20 so as to be movable back and forth. ing.

That is, the lower end of the stopper piece 19 protrudes below the label receiver surface so that the end comes into contact with the stopper piece 19 when the label slides on the label receiver surface.

The label receiver of the high-pressure air blowing device 13a is located approximately midway down between the surface 16 and the label peeling position 4, and the label receiver is provided with a large number of injection ports 22 that spray air toward the surface.

In the label pasting machine of the present invention having the above-described structure, when the printed label a is peeled off from the mount 3 and fed out from the peeling position, the two-way switching valve 11 is operated to close the communication pipe 12 and close the communication pipe 13. is opened to the high-pressure air source 10, and the label holder holds the label a on the surface 16 by the air blowing device 18a.

The label a is held at an accurate position with its end abutting against the stopper piece 19, and waits for the article A to be moved.

Next, when the communication pipe 13 is shut off by the two-way switching valve 11, and the communication pipe 12 is opened to feed the high pressure element A1 into the high pressure chamber 15, high pressure air from the nozzle pipe 17 is blown onto the back side, and the label a is It is affixed by flying onto article A.

In the label pasting machine of the present invention having the above configuration, the stopper piece 19 is provided with the elongated hole 20 for adjusting the position according to the air flow rate, the size of the label, etc., so the adjustment is easy. Since the stopper piece 19 always reliably holds the label in an accurate position, there is an effect that the label will not shift when attached to the article.
