Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for applying labels to the surface of bottles.

Prior Art and Problems to be Solved by the Invention Conventionally, a take-out device in which a plurality of take-out plates are attached at equal angular intervals is installed on a rotary table, and a gluing roller and a large number of labels are stacked around the take-out device. By rotating the rotary table in one direction, the gluing roller is brought into contact with the adhesive surface formed on the outer surface of the take-out plate to form a glue film, and the labels in the magazine are attached. The structure is such that the adhesive is pasted on the adhesive surface and taken out, and a pasting device in which a plurality of delivery plates are attached to a rotary table at equal angular intervals is disposed between the take-out device and the bottle conveyance line, and The label for the bottle is peeled off from the label affixed to the take-out plate of the take-out device by rotating in one direction, is delivered to the receiving surface of the delivery plate, and is affixed to the surface of the bottle on the conveyance line. Pasting devices are well known, but conventional label pasting devices of this type rotate the rotary tables of the take-out device and the pasting device in opposite directions at the same circumferential speed to prevent the take-out plate and delivery plate from slipping. Previously, labels were transferred by rolling the gripper while it was rotating, but in order to transfer the label while it was rotating, it was necessary to control the timing of the operation of the gripping tool extremely tightly, and the timing was slightly off. In some cases, it may not be possible to transfer labels by just using the printer, which has the drawback of unstable operation.

Means for Solving the Problems The present invention, as a means for solving such problems, sets the rotary tables of the take-out device and the pasting device so that the take-out plate and the delivery plate are at angles corresponding to each other. an index table that is temporarily stopped and rotates intermittently;
At the same time as attaching the gear, a second gear having a pitch circle having the same curvature as the adhesive surface of the extraction plate is aligned with the adhesive surface and formed integrally with the extraction plate, and the extraction plate is made to correspond to the delivery plate. and a swing device that swings the take-out plate in a state where the second gear is meshed with the first gear.

Effects and Effects of the Invention The present invention has the above configuration, and the label is transferred from the take-out plate to the transfer plate when both the index tables of the take-out device and the pasting device are stopped.
Since the extraction plate is oscillated relative to the delivery plate under exactly the same conditions as the meshing of the first and second gears, the adhesive surface of the extraction plate does not slip at all against the receiving surface of the delivery plate. Therefore, the label is transferred reliably to the transfer plate without wrinkles or tears.
