Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut tape sticking device used for continuously sticking a cut tape to a continuous sheet material such as corrugated cardboard.

Conventional technologyIn order to make it easier to open a box made of sheet material such as corrugated cardboard, the side of the box can be divided into two parts by tearing the side of the box in advance inside the box along the tearing position. The cutting tape that goes around is attached and placed.

This cut tape is stuck on one surface of a corrugated board or the like by using a cut tape sticking device when continuously producing a sheet material for a box which is later folded into a box from a corrugated board or the like.

A conventional cutting tape sticking device includes a reel for feeding the cutting tape, a holding unit for temporarily holding the free end portion of the cutting tape at the standby position, and a touch roll capable of moving from the raised position to the sticking position. It was a simple one that was equipped and used by mounting it on a fixed beam.

In the conventional cutting tape sticking device, before starting the operation of cutting tape sticking, the worker first
Take the free end of the cutting tape hanging from the reel, guide it to the holding unit by passing it between the corrugated cardboard etc. and the touch roll in progress, and temporarily fix the free end of the cutting tape to the holding unit. I had to do it. It goes without saying that the work of passing the free end portion of the cutting tape between the corrugated cardboard and the like and the touch roll in progress is a dangerous work.

In addition, since the free end portion of the cut tape held in the holding unit is located upstream of the cut tape that is attached to the corrugated cardboard or the like by the touch roll at the start of operation, the length of the cut tape is relatively long. In this case, there was a risk that the free end would get wrapped around and cause trouble.

Further, as in the device described in JP-A-56-28847, the holding unit is made of a single-sided adhesive tape, and at the start of the operation, the free end portion of the cutting tape is connected to the holding unit to form the holding unit. , If the tape is attached to the corrugated cardboard along with the free end of the cutting tape, in addition to the dangerous work of passing the free end of the cutting tape between the corrugated cardboard and the touch roll in progress, It was necessary to make the holding unit necessary for starting the operation each time and to attach it to the device.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention An object of the present invention is to provide a cutting tape attaching apparatus which does not require the above-mentioned dangerous work and troublesome work of the worker.
