Description

[Detailed Description of the Invention] [Purpose of the Invention] (Industrial Application Field) The present invention relates to a labeling device for a stack of flat packaging that applies labels to a plurality of mutually different sides of a stack of flat packaging.

(Prior art) Currently, labeling operations at paper mills involve collecting a pile of flat-packed items, gluing them together, and then manually pasting labels one by one.
There were problems in terms of labor saving and efficiency. Taking this interval into consideration, after the suction tool adsorbs the label in the supply section, the suction tool is reversed to apply glue etc. to the label and face the stack of flat packages, and then the cylinder is used to wrap the flat packages. Japanese Patent Application Laid-Open No. 13633/1983 proposes a label that can be pressed onto a pile and pasted thereon. This makes it possible to automate and save labor by automatically repeating label suction and pasting by reversing the suction device.

(Problem to be solved by the invention) As mentioned above, the device disclosed in the above publication is capable of automatically attaching labels to a pile of flat packages, but it is only possible to attach labels to one side of the pile of flat packages. If this is not possible and it is necessary to apply labels to three or four sides of a pile of flat packages, for example, the label must be applied while rotating the pile of flat packages using a turntable, which prevents the line-up of the labeling process. That was the reality.

Therefore, the present invention has been developed in consideration of this situation, and provides a labeling device for a pile of flat packaging that makes it possible to perform the labeling process on a plurality of mutually different sides of a pile of flat packaging in a line. The purpose is to

Since the label 14 can be pasted and the suction operation can be performed by one reversal of the 2A, an example has been shown in which the label can be pasted twice by one rotation of the suction tools 12 and 12A. The suction tool may be operated in reverse as in the above publication. Also, a cylinder or the like may be used instead of the electromagnetic drive device, and a rotary encoder and motor may be used instead of the servo motor.
Further, the actuating device may be appropriately selected, such as using an air motor for intermittent rotation. In addition, as a means for intermittently moving the receiving part, a comparator that can be adjusted by an appropriate means may be connected to the rotary encoder to measure and adjust the thickness of the pile of flat packages in advance, or an appropriate sensor may be used to adjust the labeling area of the package. It may be sensed or it may be controlled by a computer and may be selected as appropriate.
