Regarding

[0002]

2. Description of the Related Art In the manufacturing industry and the like, labels each having a back surface coated with an adhesive are peeled one by one from a mount and attached to a product or the like. Hereinafter, in this specification,
The function of peeling the label, which has been coated with the adhesive on the back surface and printed on the front surface immediately before, from the backing sheet and delivering it to the label sticking device is called "label delivery".

An example of the conventional equipment configuration around a label transfer device including an accessory device will be described with reference to FIG.
1 is a label / backing paper supply reel, 2 is a backing paper take-up reel that winds only the backing paper after stripping the label, 3 is a label, 4 is a backing paper, 5 is a carbon paper supply reel, 6 is carbon paper, 7 is carbon A paper take-up reel, 8 is a platen of the printer, 9 is a peeling edge, and 10 is a suction pad.

The label 3 having an adhesive applied to the back surface is 1
The labels are attached one by one to a belt-shaped mount 4, and are rewound and supplied from the label / mount supply reel 1. Mount 4
Is a strip of so-called release paper that has been subjected to a treatment such as applying silicone oil so that the label 3 can be easily peeled off. On the other hand, the carbon paper supply reel 5 is on the upper surface of the label.
The carbon paper 6 is supplied from the platen, the platen 8 prints the required items on the label 3 immediately before the peeling, and the used carbon paper 6 is wound on the carbon paper take-up reel 7. The label 3 and the backing sheet 4 proceed as they are, and when they reach the peeling edge 9, the backing sheet 4 is squeezed at an acute angle and the label 3 peels off, and an adhesive is applied to the vacuum suction pad 10 of the label sticking apparatus standing by above. The surface not coated with is adsorbed, and is moved to the surface of the product or the like by a moving means (not shown), pressed and adhered.

FIG. 8 is an explanatory view showing the main part of the label delivery device for explaining this transition. In FIG. 8A, the first label is shown.
3a is being printed, and in (b), the first label 3a is peeled from the backing sheet by the peeling edge 9, and the leading end is a suction pad.
It has been sucked to 10, and the subsequent second label 3b has not been printed yet. In (c), the first label 3a is completely sucked by the label applying head 10, and the backing sheet 4 is back-fed until the second label 3b comes to a position before the platen 8, and the second label 3a is fed. Printing of 3b has started.

[0006] The order of the products sent may be out of order for some reason, and if the contents of the label are printed in advance, the correspondence between the product and the label may be broken. Therefore, printing is performed at the timing immediately before sticking, and the finished label is immediately delivered to the label sticking device. However, at this point, the next label generally passes the print position. When the delivery of the first label is completed,
It is necessary to back feed the mount once to the print position and print the next label.

In recent years, industrial robots have become widespread, and by attaching a label attaching device to a robot hand, it is possible to freely attach a plurality of positions and a plurality of types of labels by utilizing the memory capacity of the robot. It has become possible. However, the apparatus configuration shown in FIG. 7 is slow in processing time, and cannot be applied to the case of attaching with high efficiency or attaching a plurality of different types of labels. Therefore, an attempt has been made to improve efficiency by installing a plurality of suction pads for receiving the label peeled from the mount on one label producing apparatus. An example of the device configuration is shown in FIG.

The configuration of FIG. 9 is the same as that of FIG. 7 up to the peeling edge 9. A label receiving table 11 is arranged in connection with the peeling edge 9. The label receiving table 11 moves away from the peeling edge 9 every time a label is received, moves to a plurality of suction pads 10a or 10b for label attachment, and delivers the label.

[0009]

By the way, in the conventional label transfer device as described above, when the label is peeled from the mount, the label once peeled may come into contact with the surface of the mount and adhere. If they come into contact with each other, they may be pulled back along with the movement of the back feed of the mount, the label cannot be adsorbed to the adsorption pad 10, and the automatic operation stops. It is an object of the present invention to eliminate such a delivery error due to contact adhesion of a once peeled label and to realize a label delivery device capable of automatic operation.
