Abstract

PURPOSE:To provide a label pasting apparatus highly reliable in label pasting which completely synchronizes feeding of a label tape to improve reliability of a mechanism by feeding a label on the label tape from a label tape carrier to a pasting base by one label pitch by a label tape driving mechanism. CONSTITUTION:A mount 12 is forced to be bent by a peeling edge 3 to peel a label 2 off the mount 12. A label tape carrier 4 and a pasting base 6 opposite to the label tape carrier 4 are provided. A label suction head 7 reciprocating between the label tape carrier 4 and the pasting base 6 is placed. A head feed mechanism 9 and the label suction head 7 are coupled via a buffer spring 10, wherein when there is difference between their speeds, the buffer spring 10 deflects to automatically realize synchronization. Thus synchronization between the label suction head and the label tape at the time of peeling can be securely obtained, thereby preventing a drop in reliability in pasting due to difference in moving speeds.

The label suction head 7 is connected to and driven by a head feeding mechanism 9 which is reciprocally driven between the peeling edge 3 and the sticking base 6, and The linking site head feed mechanism 9 and the label suction head 7, the buffer spring 10 is achieved by providing a labeling machine which is interposed.

[0012]

In the present invention, the label suction head 7 is connected to the head feeding mechanism 9 and is reciprocally driven between the sticking base 6 and the peeling edge 3 of the label tape carrier 4. The head feed mechanism 9 and the label suction head 7 are connected via a buffer spring 10, and when a difference occurs in the feed speed between the two, the buffer spring 10 is bent and automatically synchronized.

As a result, the label suction head 7 and the label tape 1 are reliably synchronized during the peeling operation, and it is possible to prevent deterioration of the sticking reliability due to the difference in the moving speed between the two.
